REMOTE OPERATIONS DEVICE
FIELD OF INVENTION
The present invention relates to devices for performing actions and operations remotely from a user. Optionally but not essentially, the device may be a surgical device such as an endoscope and associated devices and methods for operating an endoscope.
BACKGROUND OF INVENTION
Devices for performing examinations and actions in spaces where physical access and/or line of sight is difficult to obtain endoscopes and borescopes.
Applications for such devices include endoscopes for medical and surgical use and borescopes for accessing enclosed spaces in complex machinery.
Such devices typically consist of a proximate end that includes operating controls and image viewing apparatus, an intermediate portion that typically include a rigid or flexible shaft or tube and a distal end that typically includes image collection system and often one or more devices such as scissors, manipulators, cauterisers, gas/liquid injectors, suction equipment, lighting apparatus and/or the like.
An example of image collection arrangement has the image collection system comprising a lens system, connected to fibre optic cabling for relaying the image collected by the lens system through the shaft or tube to the image viewing apparatus (e.g. a CCD or CMOS imaging system, in turn collected to a processing device and screen, or an eyepiece) at the proximate end. Another example of an image collection arrangement has the imaging system at the distal end, and the signal transmitted back to the proximate end for viewing on a screen.
Movement of the endoscope and operation of any devices at the distal end is typically carried out using cables that extend from the proximate end to the distal end and can be retracted and extended by operating a suitable controller at the proximate end, in order to pull or release the cables to operate the endoscope and/or any devices at the distal end.
It may be at least one object of at least one embodiment of the present invention to obviate or mitigate at least one problem with the prior art.
It may be at least one object of at least one embodiment of the present invention to improve the precision and/or dexterity of use of a remote operations device such as an endoscope or borescope.

DETAILED DESCRIPTION OF DRAWINGS
Figure 1 shows an endoscope 5 or borescope apparatus according to an embodiment of the present invention. Although the embodiment will be described hereafter with reference to an endoscope 5, it will be appreciated that the description is equally applicable to a borescope. The endoscope 5 or borescope allows a user to carry out imaging or operations using tools at a location that is remote from the user.
In particular, in use, a tip end 10 of the endoscope 5 is generally located at the remote location, such as within a body, apparatus, or other environment where clear line of sight is difficult to obtain, whilst the other/opposite end 15 of the endoscope 5 is located at a different location, e.g. outwith the body, apparatus, or other environment.
The endoscope 5 comprises a user end unit 20 provided at a back or proximal end 15 of the endoscope, an intermediate portion 25 and a tip end unit 30 located at a front or distal end 10 of the endoscope 5, as shown in Figure 2. It will be appreciated that these may be selectively connectable together in a modular system or one or more or each of these units or portions may be integral.
The user end unit 20 comprises a handle portion 35 that is provided toward the user. The user end unit 20 also comprises any controls required to operate the endoscope 5 and connections to a controller 40 (see Figure 20) for controlling the endoscope 5 and processing data and displays for displaying images to the user.
The intermediate portion 25 comprises a hollow tube comprising rigid 45 and flexible 50 portions and extends from the user end unit 20 to the tip end unit 30. The flexible portions 50 of the intermediate portion 25 allow the endoscope 5 to extend along a tortuous or non-linear path between the user end unit 20 and the tip end unit 30. Cables, wires, fibre-optics and/or other services (not shown) that extend between the user end unit 20 and tip end unit 30 are located within the hollow intermediate portion 25.
As shown in Figures 1 to 8, the tip end unit 30 comprises a sealed digital camera 55 for capturing images and a light emitter 60. Examples of suitable light emitters 60 include a light source, e.g. an LED light source, or a lens that is connected to a fibre optic cable arrangement for emitting light transmitted from a light source at the user end 15 through a fibre optic cable arrangement running through the intermediate portion 25 to the lens. In this way, in use, the environment around the tip end 10 of the endoscope 5 can be illuminated using the light emitter 60 and images of the environment around the tip end 10 of the endoscope 5 can be captured using the camera 55. Optionally, the tip end 10 of the endoscope 5 can comprise one or more other systems conventionally found in or usable with endoscopes such as gas or liquid supply or injection apparatus, suction apparatus and/or sample or fluid collection apparatus, which may communicate gas and/or liquid between the user end 15 and the tip end 10 via suitable conduits located within the hollow intermediate portion 25.
The tip end unit 30 is also provided with one or more (in this example two) tool handling systems 65a, 65b mounted onto a support structure 70. In this way tools (not shown) can be mounted onto the endoscope 5 and each tool can be manipulated using a respective tool handling system 65a, 65b provided in the tip end unit 30 of the endoscope 5.
As shown in Figure 9, the support structure 70 comprises a rigid member that may be metallic or polymeric, for example, that has been formed with a pair of mounting portions for rotatably mounting the tool handling systems 65a, 65b, a mount for mounting the camera 55 and light emitter 60 on an underside of the support structure 70, and a plurality of chambers 80a-d, 85a-d for housing a plurality of micromotors 90a-90d for operating the tool handling systems 65a, 65b and a plurality of linear displacement sensors 95a-95d in the form of microstrain sensors, for example, for measuring an actual configuration or position of the tool handling systems 65a, 65b.
The support structure 70, camera 55, micromotors 90a-90d, tool handling systems 65a, 65b, linear displacement sensors 95a-95d and light emitter 60 are all provided within a housing 97, as shown in Figures 3 to 6.
In this particular example, each tool mounting system 65a, 65b comprises four pads, that are operable together to provide the necessary articulation of the tool.
As shown in Figures 10 to 16, each tool handling system 65a, 65b comprises a mount support part 100 (see particularly Figure 14) that is rotatably mounted to the support structure 70 of the tip end unit 30. The mount support part 100 comprises a generally (-shaped piece having a shaft 105 that is rotatably mounted to the support structure 70, a flange 110 extending laterally from the shaft 105 for coupling to an associated linear actuation member 115b, 115d, and a U-shaped support 120 that extends from an end of the shaft 105 that is opposite to the end of the shaft 105 that is rotatably mounted to the support structure 70. The U-shaped support 120 comprises a pair of facing arms 1 25a, 1 25b that are provided with holes 1 30a, 1 30b or other means for allowing a tool mount 140 to be pivotably mounted to the U-shaped support 120.
As shown in Figure 13, the tool mount 140 comprises a hollow cylindrical portion 145, having spherical or curved outer wall portions 150, a pair of pivot members 155a,b extending from opposite sides of the curved outer wall surface 150 and a flange extending from the outer wall surface 150 perpendicularly to the pivot members 155a,b. The flange 160 is arranged to couple to a corresponding linear actuation member liSa, 115c via a rotatable cap 165 (see Figure 16) and a link member 170 (see Figure 15). In particular, the hollow cylindrical portion 145 defines a guide channel 175 for receiving part of a flexible tool. The flexible tool may comprise, by way of example only, a pair of scissors, snips, grabbers, manipulators, a cauterizer, an injection system, a gas or fluid supply system, and/or the like. However, it will be appreciated that any suitable endoscope tool known in the art could be used.
Optionally, the cylindrical portion 145 is arranged to grip the part of the tool located in the guide channel 175 in a press fit manner to ensure precise movement of the tool.
Alternatively, the cylindrical portion 145 may be configured to loosely or slidably grip the part of the tool, to allow the tool to be rotated around its longitudinal axis and/or moved or translated, e.g. in the forwards/backwards directions, e.g. under the action of an external unit, as described below.
As shown in figures 10 to 12 and 16, the cap 165 is rotatably fitted to the flange and the link member 170 is fitted to the cap 165 by way of an arcuate extending part 180 of the link member 170 that extends through a corresponding passage 185 in the cap 165 such that the cap 165 moves with the link member 170 but has a degree of lateral sliding motion along the extending part 180. The link member 170 extends round from the cap 160 to a position laterally of the tool mount 140 and U-shaped support 120 and is rotatably mounted on the support structure 70 by a pivot member 190. A slotted flange 195 extends from the link member 170 which is in turn coupled with the corresponding linear actuation member 1 iSa, 1 15c. For example, a bar 200 or other part (see Figure 5) provided at an end of the relevant linear actuation member liSa, uSc extends through the slot 205 in the slotted flange 195. In this way, even though movement of the linear actuation member liSa, uSc pivots the link member around a rotational axis 210 extending through the pivot member 190, the slot 205 and bar 200 arrangement allows a degree of relative motion between the slotted flange 195 and the bar 200 of the linear actuator liSa, uSc to accommodate the rotation of the slotted flange 195 of the link member 170.
It will be appreciated that, in this arrangement, the tool mount 140 pivots with the link member 170 via the cap 165. As such, movement of the linear actuation member 1 iSa, ii Sc attached to the slotted flange 195 of the link member 170, e.g. in a forward or backward direction, pivots the link member 170 around the rotational axis 210 through the pivot member 190 of the link member 170 with respect to the support structure 70. This pivoting motion of the link member 170 is transferred to the cap 165 via the extending part 180 of the link member 170 extending through the passage 185 in the cap 165 so as to cause the cap 165 to move/rotate with the link member 170.
Since the cap 165 is mounted on the flange 160 of the tool mount 140, then the motion / rotation of the cap 165 with the link member 170 is transferred to the tool mount 140 so as to rotate the tool mount 140 around a rotation axis 215 that extends through the pivot members 155a, 155b of the tool mount 140 and the corresponding holes 130a, l3Ob or recesses in the U-shaped support 120.
In addition, another of the linear actuation members llSb, 115d is rotatably coupled to the flange 110 on the shaft 105 of the mount support part 100 (e.g. via a linkage of the linear actuation member 115b, 115d loosely extending through a hole in the flange 110 of the mount support part 100). As such, when the linear actuation member 115b, 115d is actuated, e.g. in a forward or backward direction, the mount support part 100 (and thereby the tool mount 140, which is supported upon it) is rotated around a rotational axis 220 extending through the shaft 105 of the mount support part 100. Since the cap 165 is rotatably mounted to the flange 160 on the tool mount 140, then the rotation of the tool mount 140 via rotation of the mount support part 100 can be accommodated without interfering with the pivoting action of the link member 170, since the rotational motion of the tool mount 140 around the rotation axis 220 through the shaft 105 of the mount support part 100 is not transferred to the cap 165.
It will be appreciated that the rotation axis 220 about which the mount support part 100 is rotated (i.e. a longitudinal axis of the shaft 105 of the mount support part 100) is perpendicular to the rotation axis 215 through which the tool mount 140 is rotated by the other linear actuation member liSa, uSc (i.e. an axis 215 through the pivot members 155a, 155b of the tool mount 140). In this way, motion with two degrees of freedom may be provided in a smooth manner with a compact mechanism.
As shown particularly in Figures 8 and 9, the support structure 70 comprises four sensor chambers 85a-d for housing respective linear displacement sensors 95a-d a pair of passages 225 for routing flexible portions 230 or cables of the tools, and four motor chambers 80a-d, each motor chamber 80a-d housing one of the micromotors 90a-d.
In particular, each side (e.g. left and right) of the support structure 70 houses an upper micromotor 90a, 90c for moving the tool mount 140 of a respective tool handling system 65a, 65b and a lower micromotor 90b, 90d for moving the mount support part of a respective tool handling system 65a, 65b. In particular, each micromotor 90a- d is configured to linearly displace a corresponding rigid linear actuation member liSa-d. Various linear actuation mechanisms are known in the art and include a dry friction motor, a worm drive, a piezoelectric motor or actuator, a screw drive and/or the like.
The micromotor 90a-d may comprise an electrically or ultrasonically driven micromotor, such as a piezoelectric, electrostatic or ultrasonic motor, for example. However, it will be appreciated that other suitable micromotor or linear drive or actuation mechanisms, as would be apparent to a skilled person, could be used.
For example, each micromotor 90a-d may be a Faulhaber 03A S3 linear actuator. The micromotors 90a-d have, for example, a diameter of 3.4mm, a length of 22.85mm and a reduction ratio of 125:1. For example, the micromotor 90a-d can generate 2.8 N of continuous push force and 4.2 N of intermittent push force at a maximum speed of 24mm/mm.
Each linear actuation member 115a-115d is coupled between a corresponding micromotor 90a-90d and pivotably attached to the slotted flange 195 of the link member 170 (in the case of the upper linear actuation members 1 15a, 1 15c I micromotors 90a, 90c) or the flange 110 of the mount support pad 100 (in the case of the lower linear actuation members 115b, 115d I micromotors 9Db, 90d). In this way, the mount support part 100 can be selectively rotated on the support structure 70 around a rotation axis 220 in opposing rotational directions by linear motion of the associated lower rigid linear actuation member 115b, 115d by the corresponding micromotor 9Db, 90d toward or away from the tool handling system 65a, 65b. Similarly, the tool mount 140 can be selectively rotated in opposing directions around a rotation axis 215 that is perpendicular to the rotation axis 220 of the mount support part 100 by the associated linear actuation member liSa, uSc and micromotor 90a, 90c. In this way, the tool, which extends through the guide channel 175 in use, can be rotated through two perpendicular degrees of freedom using the tool handling system 65a, 65b.
Since two tool handling systems 65a, 65b are provided, then two tools can be independently operated in this manner.
By providing the above arrangement of micromotors 90a-d located in the front or distal end tip unit 30 of the endoscope 5 to operate tip end tool handling systems 65a, 65b, the tools can be manoeuvred more precisely but at the same time, the tip end unit 30 can be substantially kept within the dimensions of a conventional endoscope tip.
As described above in relation to Figures 8 and 9, the support structure 70 houses four linear micro strain displacement sensors 95a-d that enable calculation of an actual orientation / position of an associated guide channel 175 of the corresponding tool handling system 65a, 65b. This is important as the information obtained by comparing an expected orientation/position change of the guide channel and the actual orientation position change of the guide channel 175 allows tissue resistance to be inferred. This in turn can be used to determine an appropriate haptic feedback to the user.
As shown particularly in Figures 2 and 17, the tip end unit 30 is connected to a user end unit 20 by the hollow intermediate portion 25 that comprises both rigid 45 and flexible 50 portions. In this way, electrical and/or fibre optic cables for carrying data, power and/or light can be routed within the intermediate portion 25 between the tip end unit 30 and the user end unit 20. The cables carry, for example, control commands to the micromotors 90a-d in the tip end unit 30 from a controller 40 (see Figure 20), power for the micromotors 90a-d, camera 55 and/or light emitter 60, light for the light emitter 60, image data from the camera 55, and data from the sensors 95a-d. The hollow intermediate portion 25 also carries flexible portions 230 of the tools between the tip end unit 30 and the user end unit 20. These flexible portions 230 of the tools allow some manipulation or control of the tools from the back or proximal end 15 by manipulating the flexible portions 230. This may provide operation of the tools and/or motion of the tools with additional degrees of freedom, for example.
As shown in Figures 17 and 18, the user end unit 20 includes the handle portion that comprises an instrument channel 235 in communication with the hollow interior of the intermediate portion 25, instrument insertion ports 240 for inserting instruments into the instrument channel 235 and a plurality of (in this case two) tool manipulation systems 245. Each tool manipulation system 245 comprises a tool engager 250 and linear actuator 255 for linearly moving the tool engager 250 within the instrument channel 235. The tool engager 250 is configured to engage with part of the tool, such as the flexible portions 230.
In optional embodiments, the tool and tool engager 250 may be configured to permit automatic engagement of part of the tool with the tool engager 250. For example, the tool engager 250 may be configured to automatically engage and couple with part of the tool when the tool engager 250 is actuated in a forward direction or toward the distal end 10 and may be configured to automatically disengage and decouple with the tool when the tool engager 250 is moved past a starting or threshold position whilst being moved rearwardly / toward the proximal end 15.
In this way, the linear actuators 255 are operable to automatically engage and disengage the tool and execute linear movement of the tool. In this case, the linear movement of the tool effected by the linear actuators 255 is co-linear with a central axis of the guide channel 175 of an associated tool handling system 65a, 65b of the tip end unit 30. Since the handle 35 of the endoscope 5 does not have to be inserted into the human body, integrated servo linear actuators 255 that are larger than the micromotors 90a-d used in the tip end unit 30 are used.
An external unit 260 containing servo actuators 262, 263 can be used to engage operating handles 265 of the tools. Through the use of the servo actuators 262, 263, the external unit 260 can control the operating handle 265 of the flexible tool to operate the tool, e.g. by effecting opening and closure of the tool, and deliver rotation movement of the tool. In essence, this external unit 260 performs the task of an endoscopic nurse who controls the endoscope 5 upon request by the endoscopist.
In particular, the external unit 260 comprises a housing 270 containing an instrument engager 275 rotatably mounted relative to the housing and a rotatable actuator 262 for rotating the instrument engager 275. The instrument engager 275 comprises a first engaging member 280 for coupling to a first part 285 of a tool operating handle 265 and at least a second engaging member 290 for engaging a second part 295 of the tool operating handle 265. At least one of the engaging members 280, 290 (e.g. the first engaging member 280) comprises an engagement sensor 300 for determining if the associated engaging member 280 is engaged with the appropriate part 285 of the tool operating handle 265. If it is determined that the first and/or second engaging members 280, 290 are engaged with the respective parts 285, 295 of the tool operating handle 265 then the second engaging member 290 is movable (e.g. linearly movable) relative to the first engaging member 280 under the action of the linear actuator 263. In this way, the external unit provides an automated mechanism for rotating the tool by operating the rotatable actuator 262, which in turn rotates the flexible part 230 of the tool by virtue of at last the first part 280 of the tool being coupled to the first engaging member 280. The external unit 260 also provides an automated mechanism for operating (e.g. opening and closing) the tool by relative movement of the first and second engaging members 280, 290, engage different parts 285, 295 of the tool operating handle 265 to thereby perform relative motion of the parts 285, 295 of the tool handle 265 that result in operation (e.g. opening/closing) of the tool. Optionally, control of the external unit 260 is by wireless communication from the controller 40 (see Figure 20).
Through the combined effect of the actuators 255, 262, 263 and micromotors 90a-d of the tip end unit 30, the user end (handle) unit 20 and the external unit 260, each endoscope 5 will have up to five degree of instrument movement, namely rotation around the two axes provided by the tool handling system(s) 65a, 65b in the tip end unit 30, linear displacement (e.g. into or out from the tip end) using the linear actuators 255 in the handle 35 and rotation of the tool around its longitudinal axis and operation of the tool provided by the external unit 260 acting on the tool operating handle 265.
The operation and coordination of these three units is performed by the controller 40 responsive to a manually operated control device 305, as shown in Figure 20.
The controller 40 comprises a processing unit 310 coupled to a communications system 315. The controller 310 is also coupled to a display 320 for displaying images collected by the camera 55 in the tip end unit 30 of the endoscope 5. The communications system 315 is configured to communicate with the control device 305 for receiving input from the user or operator and for providing haptic feedback to the user or operator under the control of the controller 40. The communications system 315 is also configured to communicate with the external unit 260 for providing control commands from the controller 40 to the external unit 260 for performing rotation and/or operation (e.g. opening and/or closing) of the tools. The communication system 315 communicates with the user end unit 20 (e.g. the handle 35) of the endoscope 5 in order to provide operational commands such as commands for operating the actuators 255 in the user end unit 20, e.g. in order to engage and/or disengage the tools and to move the tools, e.g. in a forward or distal direction and/or in a backwards or proximal direction. The communications system 315 is also configured to communicate with the tip end unit 30. The communications to the tip end unit 30 can comprise indirect communications, i.e. via the communications link to the user end unit 20 and thereby via an electrical, optical or wireless data cable or link through the intermediate part 25 of the endoscope 5 to the tip end unit 30. Alternatively or additionally, the communications with the tip end unit 30 comprise direct communications, e.g. via a wireless link directly to the tip end unit 30. In this way, control commands for operating the micromotors 90a-d to move the tools and/or commands for operating other components such as the camera 55, light emitters 60, gas or liquid supply, suction system and/or the like may be transmitted from the controller 40 and/or data, signals or images from the sensors 95a-d and camera 55 may be received by the controller 40.
Control of the endoscope 5 is through a five degree of freedom haptic control device 305 that is in communication with the controller 40 via the communications system 315. The user can input control commands or actions using the control device 305, which are then interpreted by the controller 40 using pre-programmed control algorithms that allow the controller 40 to output suitable commands to the endoscope 5 and/or external unit 260 in order to operate the external unit 260 and/or endoscope 5 to give effect to the user's intentions.
In addition, the controller 40 is configured to determine appropriate haptic feedback to provide to the user or operator using the haptic control device 305. In particular, the actual orientations / positions of the guide channels 175 of each of the tool handling systems 65a, 65b are received by the controller 40 from the linear displacement strain sensors 95a-d in the tip end unit 30. This allows the controller 40 to make a comparison of an expected orientation/position change of each guide channel 175 as transmitted to the niicromotors 90a-d via corresponding control commands from the controller 40 and the actual orientation position change of the guide channels 175 as measured by the corresponding linear displacement strain sensor 90a-d. This comparison can be used to infer tissue resistance experienced by the appropriate tool. The controller 40 is then arranged to determine an appropriate haptic feedback to the user based on this determination of tissue resistance. For example, the haptic feedback may be provided by one or more haptic feedback units 325, such as for example pressure application or vibration units on the control device, varying the stiffness or resistance of one or more controls on the control device, and/or the like.
In this way, the above system is operable to automate or robotise operation of the endoscope 5 with a high degree of precision and dexterity whilst at the same time providing a high degree of feedback to the user or operator.
Although one embodiment of the invention is described above, one skilled in the art will understand that various other arrangements are possible without departing from the scope of the present invention.
For example, although the above example provides automation of the endoscope 5 and/or associated tools via the external unit 260, the back or proximal (handle) end unit 20 and the front or distal (tip) end unit 30, it will be appreciated that it is not necessary to provide all of these automation options and that each may be used separately and/or in various combinations.
In addition, although the external unit 260 is external to the endoscope 5, the functionality and/or components provided by the external unit 260 may optionally be integrated into the endoscope 5.
Furthermore, although various examples of tools have been described above, it will be appreciated that other suitable tools for use with endoscopes or borescopes would be apparent to a person skilled in the art.
Although the above example is described in relation to an endoscope 5, it will be appreciated that the features and concepts described above are equally applicable to other remotely operated devices such as borescopes and the like.
Although the endoscope 5 described above could be used in a medical or surgical environment, it will be appreciated that it is in no way limited to that application and is equally suitable for other applications such as the inspection of, and carrying out operations on, machinery, performing investigations and operations in hazardous environments, viewing or performing operations in environments with restricted line of sight, and/or the like.
As such, the above specific examples are given for illustration only and the scope of the invention is limited only by the claims.
