  The posture when the surgeon operates the foot switch is assumed to be used in various postures such as standing or sitting depending on the content of treatment. However, the same type of foot switch is used regardless of the posture of the surgeon.

  In general, a foot switch that is assumed to be used in a standing position can be output by placing the pedal at a shallow (small) elevation angle and intentionally shifting the weight of the operated foot. It is considered that it is desirable from an ergonomic point of view. On the other hand, in the case of a foot switch used in the sitting position, take a deep (large) elevation angle of the pedal so that it fits the natural posture at the time of sitting and apply some force in addition to the weight of the foot. It is considered desirable to be configured to output at

  As shown in FIG. 1, for example, a treatment system (control system) 10 used for medical purposes according to this embodiment is, for example, an ultrasonic device or an electric scalpel device (described here using an ultrasonic device). An apparatus main body (control apparatus) 12 which is a main apparatus is provided. Inside the apparatus main body 12, when a signal is input through the cables 37a and 37b from foot switches 36a and 36b, which will be described later, a control unit 14 that determines the signal and an output from the control unit 14 will be described later. An oscillation driving circuit 16 that oscillates a signal so that ultrasonic vibration is output by the handpiece 32 is disposed in a state of being electrically connected to each other. The apparatus main body 12 includes an operation display panel 22, a pinch valve 24, a water pump 26, and first and second connector sockets 28a and 28b on its outer surface. The operation display panel 22 is integrally provided with a display member such as an LCD and operation buttons (not shown), for example. The operation display panel 22 displays various settings, the type of operation selected, the operation state, and the like, and various operations are performed on the operation display panel 22.

  A plug 32b can be attached to and detached from the first connector socket 28a through a cable 32a of a handpiece (control instrument) 32 of the ultrasonic apparatus. Therefore, the drive signal from the oscillation drive circuit 16 is transmitted to the handpiece 32 through the first connector socket 28a, the plug 32b, and the cable 32a. In this case, the operation control of the drive signal is detachable from the second connector socket 28b, and is switched by turning on / off the treatment foot switches 36a and 36b used for switching the operation of various instruments. The foot switches 36a and 36b can be connected to a plurality of foot switches 36a and 36b according to the use situation of the operator by passing through the relay connector 38 that branches the wiring. For this reason, foot switches (foot switch systems) 36a and 36b (hereinafter, mainly denoted by reference numeral 36) can be disposed at the operator's standing position.

  Next, the structure of such a treatment foot switch 36 will be described with reference to FIGS.

  FIG. 2 shows an example of the configuration of the foot switch 36. As shown in FIG. 2, the foot switch 36 includes a frame base (casing portion) 42 that constitutes an exterior frame, and a plurality of (for example, two) small pedals (second) arranged side by side on the upper surface of the frame base 42. Pedals) 44 and 46, and a partition plate 48 disposed between the small pedals 44 and 46 on the upper surface of the frame base 42. The small pedals 44 and 46 and the partition plate 48 can be attached to and detached from the frame base 42.

  As shown in FIG. 3, the frame base 42 is formed such that the proximal portion is low with respect to the operator and the distal portion is gently high with respect to the proximal portion in order to facilitate the stepping operation with the foot. A slope portion (pedal placement portion) 52 is provided. An electrical connection portion 54 having a step with respect to the slope portion 52 is disposed at the distal portion of the slope portion 52. An electrical cable 37 a shown in FIG. 1 is extended from the electrical connection portion 54. When the small pedals 44 and 46 are attached to the electrical connection portion 54, the small pedals 44 and 46 are fitted and fixed to the electrical connection portion 54.

  A pair of side frames 56 a and 56 b parallel to each other are disposed on the sides of the slope portion 52 and the electrical connection portion 54. The partition plate 48 is disposed at a substantially central portion between the side frames 56a and 56b. As shown in FIG. 2, the partition plate 48 protrudes upward from the slope portion 52 more than the small pedals 44 and 46 so as to prevent the two small pedals 44 and 46 from being pressed simultaneously. .

  The electrical connection portion 54 includes two pairs of connection ports (connection sockets, first electrical connection portions) 62 (62a, 62b) and 64 (64a, 64b) opened on the slope portion 52 side. Connection plugs (second electrical connection portions) 82a and 82b described later of the small pedals 44 and 46 are attached to the connection ports 62a, 62b, 64a, and 64b.

  In the slope portion 52, a pair of concave portions 66a and 66b are formed at substantially the center of the side frames 56a and 56b. On the lower surface of the partition plate 48, a pair of convex portions 68a and 68b that can be fitted into the concave portions 66a and 66b are formed. For this reason, the partition plate 48 can be attached to the inclined surface portion 52 by fitting the convex portions 68a and 68b to the concave portions 66a and 66b. Further, the partition plate 48 can be removed from the inclined surface portion 52 by pulling out the convex portions 68a and 68b from the concave portions 66a and 66b. That is, as shown in FIG. 3, the partition plate 48 can be attached to and detached from the frame base 42.

  The small pedals 44 and 46 can be attached to and detached from the frame base 42, respectively. Furthermore, one large pedal 50 larger than the small pedals 44 and 46 can be attached to and detached from the frame base 42.

  As shown in FIG. 4, the small pedals 44 and 46 are a pedal base 72, an operation plate (pedal upper surface cover) 74 that can be opened and closed with respect to the pedal base 72, and an operation plate 74 that is opened and closed with respect to the pedal base 72. And a pivot to make it.

  The pedal base 72 and the operation plate 74 are each formed in a substantially rectangular parallelepiped box shape. Pedal support holes 72a and 74a are formed in the pedal base 72 and the operation plate 74 at positions facing each other on the distal side with respect to the operator. The pedal base 72 and the operation plate 74 are pivotally supported by a pivot pin 82 so as to be openable and closable with respect to each other with the pivot holes 72a and 74a being combined. That is, the pivotal support portion includes pivotal support holes 72 a and 74 a and a pivotal support pin 82.

  The operation plate 74 is formed to be slightly larger than the pedal base 72 and can cover the pedal base 72. As shown in FIG. 3, the outer surface (tread surface) of the operation plate 74 is formed with a non-slip uneven 51 for preventing the operator from slipping on the back of the shoe.

  The small pedals 44 and 46 are further arranged between the detection mechanism 76 for outputting an on / off signal and the pedal base 72 and the operation plate 74, so that the position of the operation plate 74 is restored. Springs 78a and 78b disposed at two locations, and connection plugs 82a and 82b for mounting the pedal base 72 to the frame base 42.

  The pedal base 72 is formed with a pair of connection plugs 82a and 82b on the distal side with respect to the operator so that cables 77a and 77b described later are inserted therethrough. These connection plugs 82a and 82b are formed in a substantially cylindrical shape. On the bottom surface of the pedal base 72, a detection mechanism 76 that detects the pressing of the operation plate 74 and one end portions (lower end portions) of a pair of springs 78a and 78b that bias the operation plate 74 away from the pedal base 72. Spring support portions 84a and 84b are disposed. The other ends (upper end portions) of the springs 78a and 78b are received by spring receiving portions 86a and 86b arranged on the back surface of the operation plate 74. These springs 78a and 78b can be selected from a plurality of types in order to change the magnitude of the urging force and adjust the mounting angle of the operation plate 74 with respect to the pedal base 72. Note that the springs 78a and 78b normally have the operation plate 74 pulled away from the pedal base 72, and the detection mechanism 76 exerts a force in a direction indicating an off signal to be described later.

  The detection mechanism 76 includes a detection mechanism main body 76a, a push button 76b provided on the detection mechanism main body 76a, and a detection mechanism 76 for transmitting a pressing signal of the push button 76b to the outside of the small pedals 44 and 46. A pair of cables 77a and 77b extended from the cable. These cables 77a and 77b are electrically connected to connection plugs 82a and 82b, respectively. The push button 76 b is pressed by a pressing protrusion 88 disposed on the back surface of the operation plate 74 when the operation plate 74 is closed with respect to the pedal base 72. When the push button 76 b is pressed by the pressing protrusion 88, an on signal is output from the detection mechanism 76. When the pressing protrusion 88 is separated from the push button 76 b, an off signal is output from the detection mechanism 76. Therefore, the output of the on signal / off signal is selected by pressing / releasing the operation plate 74 with respect to the pedal base 72.

  Next, the operation of the treatment system 10 according to this embodiment will be described.

  As shown in FIG. 1, the plug 32 b of the hand piece 32 is attached to the first connector socket 28 a of the apparatus body 12. For this reason, the drive signal from the oscillation drive circuit 16 can be transmitted to the handpiece 32 through the plug 32b connected to the first connector socket 28a. The drive signal is turned on / off by a foot switch 36 connected to the second connector socket 28b and the relay connector 38.

  When the foot switch 36 is used, as shown in FIG. 3, the small pedals 44 and 46 and the large pedal 50 are selectively attached to the pedal base 72 according to usage. Hereinafter, the case where the small pedals 44 and 46 are used will be described.

  A partition plate 48 is attached to the pedal base 72. Specifically, the convex portions 68 a and 68 b of the partition plate 48 are attached to the concave portions 66 a and 66 b of the pedal base 72. The small pedals 44 and 46 are connected to the electrical connection portion 54 of the pedal base 72. Specifically, the connection plugs 82a and 82b of the small pedals 44 and 46 are connected to the connection ports 62a, 62b, 64a and 64b of the electrical connection portion 54, respectively. If it does so, the detection mechanism 76 of each small pedal 44 and 46 and the electrical connection part 54 will be electrically connected. The foot switch 36 in this state is connected to the apparatus main body 12 by the second connector socket 28b and the relay connector 38. Therefore, an operation signal of the operation plate 74 for the pedal base 72 is transmitted to the apparatus main body 12.

  When the foot switch 36 is used in a standing position, as shown in FIG. 5 (A), the foot switch 36 is adjusted using a height adjustment portion 90 that places the distal portion of the pedal base 72 at a higher position than the proximal portion. To do. At this time, the angle α of the pedal base 72 with respect to the floor surface is preferably set to, for example, 5 degrees to 20 degrees when the height adjustment unit 90 is used. Then, when standing, the angle of the operation plate 74 with respect to the floor surface is less likely to place a burden on the operator's legs and is easy to operate. For this reason, when an operator puts his / her foot on the small pedals 44 and 46 while standing, an excessive force is not required.

  When the foot switch 36 is used in the sitting position, as shown in FIG. 5 (B), the foot switch 36 is adjusted using a height adjustment portion 90 that places the distal portion of the pedal base 72 at a higher position than the proximal portion. To do. In this case, the angle β of the pedal base 72 with respect to the floor surface is preferably set to 40 degrees to 70 degrees, for example, when the height adjustment unit 90 is used. Then, in the sitting position, the angle of the operation plate 74 with respect to the floor surface is less likely to place a burden on the operator's legs and is easy to operate. For this reason, when an operator places a foot on the small pedals 44 and 46 in the sitting position and performs an operation, an excessive force is not required.

  When the operation plate 74 is stepped on the pedal base 72 in such a state, the push button 76b of the detection mechanism 76 is pressed by the pressing protrusion 74a on the back surface of the operation plate 74, so that the detection mechanism 76 is turned on. At this time, the detection mechanism 76 transmits the signal to the apparatus main body 12 through the electrical connection portion 54 (see FIG. 3) of the frame base 42 by the cables 77a and 77b. Various treatments can be performed by the handpiece 32 of the ultrasonic treatment instrument connected to the apparatus main body 12 by the control unit 14 and the oscillation drive circuit 16 of the apparatus main body 12.

  At this time, since the partition plate 48 protruding above the operation plate 74 of the small pedals 44, 46 is disposed between the two small pedals 44, 46, a plurality of pedals are accidentally stepped on simultaneously. Is prevented.

  In addition, when changing the use of the foot switch 36, the small pedals 44 and 46 are replaced with the large pedal 50, for example. In this case, the small pedals 44 and 46 and the partition plate 48 are removed, and the large pedal 50 is attached.

  Connection plugs (second electrical connection portions) 82a and 82b of the large pedal 50 shown in FIG. 3 are connected to the connection ports (first electrical connection portions) 62a, 62b, 64a and 64b of the electrical connection portion 54 of the frame base 42. Can be installed. That is, the small pedals 44 and 46 and the large pedal 50 are compatible. In this case, the cables 77a and 77b of the detection mechanism 76 are disposed in at least one pair of the connection ports 62a and 62b among the two pairs of connection ports 62a, 62b, 64a and 64b. For this reason, it can be used similarly to the case where the small pedals 44 and 46 are used.

  The surgeon performs an operation of appropriately depressing each of the pedals 44 and 46, thereby transmitting the information to the apparatus main body 12 by controlling the push button 76b provided inside the pedals 44 and 46 from off to on or vice versa. It is possible to control the output.

  As described above, according to this embodiment, the following can be said.

  When the operator does not need a part of the plurality of pedals 44 and 46 when using the foot switch 36, the unnecessary pedal can be easily removed. Therefore, it is possible to prevent a signal from being input to the apparatus main body 12 by inadvertently stepping on the operation plate 74 of the pedal, and to prevent unnecessary output from the apparatus main body 12. In addition, it is possible to effectively use such that the surface area of the operation plate 74, which is originally defined, can be made larger by using an enlarged area for pressing the operation plate 74 of the pedal that is frequently used. .

  As described above, since the foot switch pedal can be exchanged according to the operator's request, the output operation can be performed in the form most desired by the operator.

  Next, a second embodiment will be described with reference to FIG. This embodiment is a modification of the first embodiment. The same members as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 6A, the foot switch 36 is attached to a chair (seat) 112 on which an operator sits. The chair 112 includes, for example, a pair of support portions 114 placed on the floor surface, and a seat surface 116 disposed on the support portion 114.

  For example, one of the two support portions 114 is provided with a holding portion 118 that holds the foot switch 36. The holding portion 118 is provided with a hollow position adjustment member 120 to which the foot switch 36 is attached. The position adjusting member 120 is located between the position where the foot switch 36 is disposed below the seat surface 116 of the chair 112 and the position where the foot switch 36 protrudes outward from the lower side of the seat surface 116 with respect to the holding unit 118. It can move within a predetermined range. Further, the foot switch 36 can be rotated around the axis of the holding portion 118 by the position adjusting member 120. Therefore, the treatment system 10 has a structure in which the chair 112 on which the operator is seated and the foot switch 36 are integrated, and the foot switch 36 is uniquely disposed at the most appropriate position when the operator is seated. Is done.

  Originally, a cable 124 that communicates from the foot switch 36 to the apparatus main body 12 exists outside the holding portion 118 and the position adjusting member 120. This cable 124 also communicates with the inside of the holding portion 118 through the position adjusting member 120 from the foot switch 36. In addition, it is connected to a device such as the apparatus main body 12 of the ultrasonic apparatus through an arbitrary path in the support part 114 and the seating surface 116.

  Next, the operation of the treatment system 10 according to this embodiment will be described.

  As shown in FIG. 6A, when the surgeon performs an operation in the sitting position, first, the operator sits on the seat surface 116 of the chair 112, determines the seating position, and then moves the foot switch 36 to the holding portion 118 of the chair 112. The position of the foot switch 36 is defined by moving the foot switch 36 relatively. At this time, the relative position between the seating surface 116 and the foot switch 36 is defined by translating the position adjusting member 120 in the direction along the axial direction of the holding portion 118 and rotating it around the same direction. The

  As described above, according to this embodiment, the following can be said.

  The foot switch 36 arranged at the foot is taken out only when necessary, and is stored in a position where it does not interfere with the operator when the foot switch 36 is not used. For example, the foot switch 36 is housed by combining the movement of moving the position adjustment member 120 around the holding unit 118 by translating the position adjustment member 120 along the holding unit 118 of the support unit 114 of the chair 112. Then, a space for the operator's feet is secured.

  Thus, in order to ensure the space of the operator's feet, the foot switch 36 is not limited to one. As shown in FIG. 6B, even when the plurality of foot switches 36 are arranged at a predetermined position with respect to the chair 112, the respective selection and use are facilitated. In addition, the cable 124 that is in the way communicates from the support 114 to the interior of the chair 112, or a branch wiring is provided in the middle, so that the operator can easily use the position or change the posture. A foot switch 36 can be provided as appropriate. For this reason, the complexity by arrangement | positioning of the foot switch 36 can be improved.

  It is possible to improve the convenience for the user by always securing the space for the operator's feet, and eliminate the need to blindly confirm the location of the foot switch, which was necessary in the past. be able to.

  Next, a third embodiment will be described with reference to FIGS. This embodiment is a modification of the first embodiment. The same members as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  About 3rd Embodiment, in addition to the foot switch 36 demonstrated in 1st Embodiment, the small pedal which an operator operates is reliably among several small pedals 44 and 46 which an operator operates. Focus on making it recognizable. Specifically, the foot switch 36 displays information specific to the small pedals 44 and 46 to be operated so that the operator can easily recognize that the small pedals 44 and 46 are being operated. It has a structure that can. Hereinafter, a specific configuration will be described.

  As shown in FIG. 7, the base current of the transistor 132 is linked to the ON / OFF operation of the foot switch 36 in, for example, the inside of the apparatus main body 12 or the electrical connection portion 54 (see FIG. 3) of the frame base 42. A changing circuit 130 is provided. When a base current flows through the circuit 130, the LED 134 in the circuit 130 is turned on.

  As shown in FIG. 8A, the operation plate 74 is formed of a transparent member such as a polycarbonate material. Between the operation plate 74 and the LED 134, a light guide plate 142 made of, for example, polyester and formed of a plurality of layers of sheets having minute unevenness on the entire surface is disposed. A concave portion 142 a in which the LED 134 is disposed is formed at the end of the light guide plate 142. A light reflecting sheet made of a material such as an aluminum sheet is disposed inside the light guide plate 142 excluding the vicinity of the recess 142a where the LEDs 134 are disposed.

  In this embodiment, the time until the power or the like is supplied (output) from the apparatus main body 12 to the handpiece 32 (see FIG. 1) by the operation of the foot switch 36 is an appropriate time such as several seconds. It is preferable to set the operation to be started later. Such a time setting can be set by the surgeon according to his / her preference.

  Next, the operation of such a treatment system 10 will be described.

  When the surgeon performs an operation, the operation plate 74 is pressed to operate the foot switch 36. The push button 76b of the detection mechanism 76 is pressed, and an ON signal is transmitted from the detection mechanism main body 76a to the electrical connection portion 54 through the cables 77a and 77b (see FIG. 4). Then, a base current flows through the circuit 130 (see FIG. 7), and the LED 134 is lit. As shown in FIG. 8B, the display light from the LED 134 is guided to each sheet in the light guide plate 142. At that time, light is scattered in the surface direction by the minute unevenness of each sheet. Scattering generated by each of the multiple layers of sheets is randomly repeated and displayed as if the entire surface of the operation panel 74 is emitting light. Here, the light reflecting sheet 144 reflects light that should be scattered from the opposite surface, and has a function of improving the luminous intensity of the operation surface of the operation plate 74. Since the operation surface emits light in this way, the surgeon can easily grasp whether or not light is generated without observing which pedal of the plurality of pedals 44 and 46 is being pressed. Can do. For this reason, it is possible to easily recognize which pedal is being operated.

  Instead of the configuration for turning on the LED 134, a general vibrator such as a vibration component obtained by providing a weight eccentric to the shaft of the motor and rotating it may be provided. In that case, the difference in vibration is perceived sensuously and the small pedal that the operator steps on is recognized. As a vibration generation method, vibrators having different vibration modes may be provided on the operation plates 74 of the pedals 44 and 46, or a vibration pattern of a common vibrator may be controlled by the control unit 14. In any case, it is possible to easily recognize which small pedals 44 and 46 are operated by the operator by transmitting a unique vibration pattern to the operator's feet in response to pressing of the pedals 44 and 46. Can do.

  As described above, according to this embodiment, the following can be said.

  Even in a state where it is difficult to accurately confirm the position of the small pedals 44 and 46 to be operated by the foot switch 36, the small pedals 44 and 46 being operated can be recognized by a change in light or vibration. For this reason, it is possible to prevent as much as possible the operator's unintentional output.

  Although several embodiments have been specifically described so far with reference to the drawings, the present invention is not limited to the above-described embodiments, and all the embodiments performed without departing from the scope of the invention are described.
