Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic surgical system for generating an ultrasonic vibration, transmitting the vibration to a subject, and performing a treatment.

[0002]

2. Description of the Related Art An ultrasonic scalpel device which is capable of performing treatments such as coagulation, incision and puncture on living tissue using ultrasonic vibrations and other energies as an alternative to an electric scalpel. Ultrasound surgical systems such as a trocar and an ultrasonic trocar device have been developed, put into practical use, and widely used.

[0003] As such a surgical operation apparatus using ultrasonic waves, for example, Japanese Patent Application Laid-Open No. 9-38098 discloses a handpiece having a built-in ultrasonic vibrator attached to an apparatus main body, and a drive output from the apparatus main body. Ultrasonic vibration is generated in the ultrasonic vibrator by a signal, and the generated ultrasonic vibration is transmitted to a treatment section provided on the distal end side of the handpiece, and the treatment section is pressed against a treatment target site, thereby obtaining a living tissue. There is described a surgical device for treating sclerosis.

In such an ultrasonic surgical system, the types of handpieces that can be used are increasing as the range of application is expanded. Therefore, in order to respond to a desire to use various handpieces in one surgical operation, a configuration has been proposed in which a plurality of handpieces can be connected to the apparatus main body.

When using a plurality of types of handpieces, it is necessary to replace the connector provided at the end of the cord extending from the handpiece in the apparatus body.

Also, assuming that a plurality of handpieces are used in one surgical operation, a plurality of handpieces can be attached to the apparatus main body and these handpieces can be switched and used. Extension units have been proposed.

For example, Japanese Patent Application Laid-Open
Japanese Patent Application Publication No. 0-271135 discloses three connector ports, and a connector port to be used can be selected by operating a selection switch provided on the front panel of the extension unit. A technique has been described in which a handpiece connected to a computer can be selected. Further, the publication discloses that a hand switch for operating on / off of an output can be attached to a handpiece, and when the hand switch is operated, the operated hand switch is attached. A technique is described in which a handpiece is selected.

[0008]

However, in the apparatus described in Japanese Patent Application Laid-Open No. 2000-271135, it is necessary to operate a switch on the front panel to select a handpiece to be used. Is a non-clean area, and cannot be operated by an operator who is actually performing an operation, and is required to be operated by a nurse or the like as an assistant, which is complicated.

Further, the operator confirms the switching result by the extension unit by looking at the panel display on the main body of the apparatus. However, the operator may be in a position where it is difficult to see the panel display. In order to confirm which port was selected, it was necessary to move the position or to ask an assistant to confirm, which was troublesome.

On the other hand, a detachable connector is provided on the handpiece side so that the cord is connected to the main unit side, and one hand is selected from a plurality of types in a clean area where the operator is performing an operation. There is a technology that enables use by selecting and connecting pieces. However, with this technique, it is troublesome for a nurse who is taking in and out of the device to check which hand piece the surgeon has selected and connected to the cord.

[0011] Thus, with the techniques proposed in the past, it has not been possible to construct an ultrasonic surgical system with sufficiently good operability, and it can be said that there is room for further improvement.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an ultrasonic surgical system with good operability, which can easily replace and use a plurality of ultrasonic treatment means. .

Next, with reference to FIG. 2, the flow of the operation using the above-described ultrasonic operation system will be described.

When the operation using this ultrasonic operation system is started, first, the connector 13 of the transmission cable 10 is connected to the connector receiver 8 of the apparatus main body 2 (step S).
1). Since this connection operation is performed in an unclean area, it is performed by a nurse or the like who assists the operator.

Next, in endoscopic surgery, it is necessary to secure a port for guiding a treatment tool into the body by inserting a trocar. First, for example, the transducer used in combination with the trocar 24 having a small diameter is used. 23 to the connector 14 of the transmission cable 10 (step S

With this connection, the transducer 2

In response to the result of the determination, the control circuit 7 sets various parameters and the like so that the drive signal generated from the drive signal generator 5 is a drive signal suitable for the determined device. At this time, the control circuit 7 further
The operation / display unit 4 displays that the connected transducer 23 is used for a small-diameter trocar type handpiece (step S4).

Thereafter, when the surgeon operates the foot switch 3, a drive signal is generated from the drive signal generator 5, the ultrasonic transducer 36 is driven, and the ultrasonic trocar treatment is started. Step S5).

When the insertion of the trocar 24 is completed, the transducer 23 is connected to the connector 14 of the transmission cable 10.
Is removed (step S6).

Thereafter, the processing is divided depending on whether or not another transducer is used (step S).

That is, when using another transducer, for example, when using a scissors-type handpiece obtained by combining the transducer 15 and the scissors-type treatment tool 16, the transducer 1
For No. 5, the processing from step S2 to step S5 as described above is performed.

At this time, it is determined that the connected device is the transducer 15 by the processing in step S3, and parameters suitable for the transducer 15 are automatically set. There is no need to have the assistant nurse or the like separately operate the apparatus body 2, and the transducer can be replaced and used extremely easily. On the other hand, on the assistant side such as a nurse, the type of the replaced transducer is displayed on the operation / display section 4, so that it can be easily grasped.

When the ultrasonic scissors treatment using the scissors-type handpiece is completed, the transducer 15 is detached from the connector 14 of the transmission cable 10 in step S6.

Thereafter, even when another transducer is used, the above-described steps S2 to S6 are similarly performed.

On the other hand, if it is determined in step S7 that the transducer is no longer used, the transmission cable 10 is disconnected from the apparatus main body 2 (step S7).
8), end.

Next, a configuration example of another handpiece will be described with reference to FIG. In FIG. 3, the same parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.

The configuration shown in FIG. 3 is different from the case where the connector switching device 65 is attached to the connector receiver 8 of the device main body 2 and the transducer 15 and the scissors-type treatment tool 16 are used via the transmission cable 10. And a case in which a handpiece having another configuration described below is used.

The connector switching device 65 is selected by an input / output point 65a and an input / output point 65b that can be selectively switched, a switch 65c for switching between the input / output points 65a and 65b, and the switch 65c. And an input / output point 65d for connecting one of the input / output points 65a and 65b to the connector receiver 8 of the apparatus main body.

In the example shown in FIG. 3, the transducer 15 and the scissors-type treatment tool 16 are connected to one input / output point 65a of the connector switching device 65 via the transmission cable 10. Note that this is an example, and other handpieces as shown in FIG. 1 may be connected.

On the other hand, to the other input / output point 65b of the connector switching device 65, a handpiece of a type provided with a hollow pipe-shaped probe and emulsifying tissue by ultrasonic vibration to remove by suction is connected.

More specifically, the handpiece includes a transducer 41 as a transducer means, a transmission cable 42 integrally formed with the transducer 41, and an ultra And an ultrasonic emulsification / suction treatment tool 43 as a sonic treatment means.

The transmission cable 42 has substantially the same construction as the transmission cable 10, and includes a signal terminal 45a serving as a drive signal input terminal and a signal terminal 45b serving as an identification signal output terminal.
A connector 45 as connector means provided with
A drive signal line 46 which is connected to the signal terminal 45a and transmits a drive signal generated from the drive signal generator 5 as a drive signal transmission cable, and a discriminating element which is connected to the connection terminal 45b and described later. And a discrimination signal line 47 that is a discrimination signal transmission cable for transmitting the discrimination signal from the discrimination signal 49 to the discrimination circuit 6. However, since the discrimination signal line 47 is provided integrally with the transducer 41, No connector is provided at the end.

The transducer 41 receives the driving signal from the driving signal line 46 and generates an ultrasonic vibration, and the ultrasonic transducer 48 generates discrimination information indicating the type of the transducer 41 to generate the ultrasonic vibration. It comprises a discriminating element 49 serving as a discrimination signal generating means for transmitting the discrimination signal via the discrimination signal line 47, and a suction base 50.

On the other hand, the ultrasonic emulsification suction treatment tool 43
As described above, the hollow pipe-shaped probe 43a
It is a short type used in open surgery, which emulsifies and aspirates the tissue by ultrasonic vibration and removes it by suction, and has a water supply mouthpiece 51 for supplying physiological saline for cooling and washing. It extends from the tapered side surface on the end side.

The suction tube 50 is connected to the suction base 50.
However, a water supply tube 62 is connected to the water supply mouthpiece 51, and the suction tube 61 and the water supply tube 62 are connected to a water supply / reception tube required for performing ultrasonic emulsification suction.
The suction unit 60 is connected to the suction unit 60 to perform suction and water supply. In addition, the water supply / suction unit 60
Is controlled by the apparatus main body 2.

The transducer 41 is replaced with the ultrasonic emulsifying and aspirating instrument 43, and is a procedure for endoscopic surgery, which is an ultrasonic procedure having a length of about 20 to 30 cm used in endoscopic surgery. The tool 44 can also be connected. This endoscopic surgery treatment tool 44 also includes a probe 44a in the form of a hollow pipe.
The water supply mouthpiece 52 for supplying the physiological saline for washing is extended from the tapered side surface on the base end side, and when the endoscopic surgical treatment tool 44 is used. The water supply tube 62 is connected to the water supply base 52.

Thus, the ultrasonic suction system can be configured by adding the water supply / suction unit 60 while using the apparatus main body 2 in common.

When performing an operation using the ultrasonic operation system as shown in FIG. 3, the operation follows the flow as shown in FIG. 2, but the following points are different.

First, the connector switching device 65 is connected to the connector receiver 8 of the device main body 2. The connector 13 of the transmission cable 10 is connected to the input / output point 65 a of the connector switching device 65, and is connected to the input / output point 65 b. The connector 45 of the transmission cable 42 is connected.

The connection of the connector receiver 25 of the transducer 15 to the connector 14 of the transmission cable 10 and the attachment of, for example, a scissors-type treatment tool 16 to the transducer 15 are the same as described above.

On the other hand, for example, the ultrasonic emulsification suction treatment tool 43 is attached to the transducer 41, the suction tube 61 is attached to the suction mouth 50, and the water supply tube 62 is attached to the water supply mouth 51.

At this time, the water supply / suction unit 6
By connecting 0 to the apparatus main body 2, it becomes possible to control suction and water supply by the control circuit 7 of the apparatus main body 2.

After the above connection is made, the switch 65c of the connector switching device 65 is set to the input / output point 65.
a or the input / output point 65b, for example, by switching to the input / output point 65b side, the determination information is output from the determination element 49 in the transducer 41, and the determination information is output via the determination signal line 47 of the transmission cable 42. The signal is input to the determination circuit 6.

Thus, the discrimination circuit 6 discriminates the connected device, outputs the discrimination result to the control circuit 7, and in response to the discrimination result, the control circuit 7 causes the drive signal generator 5 to Equipment whose drive signal generated from
That is, here, various parameters and the like are set so as to be a drive signal suitable for the transducer 41 having the ultrasonic transducer 48, and information on the connected device is displayed on the operation / display unit 4.

Further, the control circuit 7 communicates with the suction / water supply unit 60 according to the discrimination result, sets the optimal parameters, and sends out a drive signal for ultrasonic oscillation by the drive signal generator 5. The water supply / suction operation by the suction / water supply unit 60 is performed in synchronization with the control.

When the switch 65c of the connector switching device 65 is switched to the input / output point 65a, the discrimination information output from the discrimination element 27 is transmitted to the discrimination circuit 6.
And the control circuit 7 receiving the result of the determination sets the optimal parameters for the transducer 15 having the ultrasonic transducer 26 and causes the operation / display unit 4 to display the information of the connected device. This is the same as described above.

The reason why the transducer 41 and the transmission cable 42 are integrally formed is to reduce the size of the handpiece and to improve operability such as handling. That is, the handpiece shown in FIG.
Since it is necessary to attach the suction tube 61 and the water supply tube 62, the provision of a connector or a connector receiver leads to a further increase in size. In addition, there is a situation in which the treatment of ultrasonic suction particularly in brain surgery is often performed alone. In view of these circumstances, the connector and the connector receiver are omitted, and the transducer 41 and the transmission cable 42 are integrated.

However, also in such a transducer 41, it is possible to adopt a connector attaching / detaching method as in the other transducers as described above.

Conversely, the transmission cable 10 may be provided integrally with the transducers 15, 18, 21, 23 as shown in FIG. 1, and the connector and the connector receiver may be omitted.

In the example shown in FIG. 3, the scissors type handpiece and the ultrasonic suction handpiece can be switched and used in one operation by the connector switching device 65. However, as a matter of course, as shown in FIG. 1, it may be used by directly connecting to the connector receiver 8 of the apparatus main body 2.

Further, the connector switching device 65 can be configured to be integrated into the suction / water supply unit 60.

According to the first embodiment, a transducer of a type in which a treatment tool having an ultrasonic vibration transmitting section is attached and detached, and a transducer integrally provided with an ultrasonic vibration transmitting section, The operator can easily use various types of handpieces at his own will within one operation. In addition, at this time, the operator only needs to connect the handpiece to the transmission cable at the operation site, and since the optimal driving parameters are set for the handpiece, complicated operations are not required. The performance is improved. Further, since the type of the connected handpiece is displayed on the operation / display unit, it can be easily confirmed.

In addition, an ultrasonic suction device which conventionally required an expensive and large system can be easily realized by adding a dedicated handpiece and a water supply / suction unit to an existing ultrasonic surgical system. It becomes possible. At this time, by further using the connector switching device, it is possible to use the ultrasonic suction device properly with an existing ultrasonic surgical system, for example, a scissors type handpiece in one operation. .

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications and applications are possible without departing from the gist of the invention.
