On the other hand, with the large-diameter hook probe 51 and the large-diameter straight scissors cover sheath 6A, the ultrasonic coagulation and incision device 11 is provided.
If it is configured, the discrimination circuit 32 discriminates that the combination is incorrect based on the combination of the read signals, and causes, for example, a warning sound to be emitted via the notification circuit 33 and the sonosurge 2B to drive the combination. No signal is supplied. In other words, the user is prevented from performing treatment using the wrong combination of ultrasonic devices. Instead of the warning sound, an LED or the like may be used to display the correctness of the combination.

Here, the procedure for assembling the ultrasonic apparatus and the confirmation of the assembled state will be described with reference to FIG.

Are read by the antenna unit 31 of the control unit 30. Next, as shown in step S5, it is determined whether or not the read combination of members is correct. When the combination is correct, as described above, the drive signal can be supplied from the sonosurge 2B to the ultrasonic coagulation / cutting apparatus 11 as shown in step S6.

On the other hand, if it is determined that the combination of the ultrasonic devices is incorrect, as described above, the process proceeds to step S7, a warning sound is emitted to notify the user, and the sonosurge 2B is used. The drive signal is not supplied to the ultrasonic coagulation / cutting device 11 in the wrong assembled state.

Thereafter, the user changes the combination as shown in step S8 and shifts to step S2. Here, if it is determined that the combination is correct, the ultrasonic coagulation / incision device 11 of the appropriate combination is acquired from the sonosurge 2B.
The drive signal can be supplied to the device.

As described above, by providing the non-contact type ID in which specific information is stored in the transducer cover, the probe and the cover sheath in which the ultrasonic transducer is integrally built, each ultrasonic apparatus is constructed. By turning on the power of the sonosurge without color-coding or marking the members, it is possible to automatically and reliably determine whether or not the assembled state of the ultrasonic device is erroneous assembly.

Further, the drive signal can be supplied from the sonosurge only in the correct combination state, and it is possible to surely prevent the treatment from being performed by using the ultrasonic device in the incorrect combination state. can do.

The non-contact IDs 7a, 7b, ... Are very vulnerable to disturbance noise. Therefore, reading is interrupted during ultrasonic oscillation.

In the first embodiment, the prevention of misassembly of the ultrasonic device has been described, but in the present embodiment, a combination of the ultrasonic probe, the transducer cover and the cover sheath will be described.

As shown in the figure, in the ultrasonic coagulation / cutting apparatus 1A, the length relationship between the probe 5 and the transducer cover 4 is important. That is, if the length relationship is not an appropriate value, there is a possibility that a sufficient function cannot be obtained.

Therefore, conventionally, the probe 5 and the transducer cover 4 are sold in combination. Therefore, when a failure occurs in either the probe 5 or the transducer cover 4, it is necessary to discard both the probe 5 and the transducer cover 4 and purchase a new combination device.

In the present invention, the length dimension (L1) of the probe 5 and the length dimension (L2) when the probe 5 and the transducer cover 4 are integrated are previously set as the non-contact IDs 7m and 7m.
It is stored in n.

Therefore, when a failure occurs in either the probe 5 or the transducer cover 4, the salesman brings the reader to the non-contact type ID 7
The length information stored in m and 7n is read, and a replacement product having exactly the same length dimension is arranged and provided to the user.
