In the apparatus of No. 6,943, the ultrasonic vibration is transmitted to the distal end of the ultrasonic probe. Therefore, during the ultrasonic treatment, an ultrasonic wave is applied to the substantially L-shaped hook-shaped receiving member at the distal end of the sheath. It is held in a stationary state where vibration is not transmitted. Therefore, when performing an operation such as peeling off a membrane-like living tissue using the substantially L-shaped hook-shaped receiving member at the distal end portion of the sheath, the living tissue is easily slipped from the hook-shaped receiving member. In fact, it has been difficult to perform these operations using a treatment tool.

用できる効果がある。Therefore, the ultrasonic incision coagulation apparatus of the present embodiment having the above configuration has the following effects. That is,
The distal end of the probe 52 is provided with the hook-shaped treatment section 41 bent and formed in a direction substantially perpendicular to the axial direction of the sheath 11, so that one ultrasonic incision coagulation device can be used as described above. In a state where the living tissue is sandwiched between the hook portion 54 of the hook-shaped treatment portion 41 of the probe 52 and the receiving member 56 at the distal end portion of the sheath 11, the hook-shaped treatment portion 41 of the probe 52 By transmitting the ultrasonic vibration, ultrasonic treatment such as ligation of a living tissue, for example, a blood vessel, between the hook-shaped treatment portion 41 of the probe 52 and the receiving member 56 at the distal end portion of the sheath 11, and the hook-shaped treatment of the probe 52 In a state where the ultrasonic vibration is transmitted to the portion 41, the distal end of the hook portion 54 of the hook-shaped treatment portion 41 is applied to, for example, a film-like living tissue, thereby separating the film-like living tissue. By applying a high-frequency current to the probe 52 or performing a high-frequency treatment such as an electric scalpel on living tissue by the hook-shaped treatment section 41 at the tip of the probe 52, the operation can be performed. it can. Therefore, since one ultrasonic incision coagulation apparatus of the present embodiment can be used for multiple functions, the usability of the ultrasonic incision coagulation apparatus is greatly improved as compared with the related art, and there is an effect that it can be used conveniently.

Since the high-frequency current is supplied to the probe 52 while transmitting the ultrasonic vibration to the probe 52, it is possible to prevent the living tissue ablated by the high-frequency treatment from sticking to the probe 52 during the high-frequency treatment. Therefore, after the high frequency treatment, a troublesome operation of dropping the living tissue stuck to the probe 52 using a tool such as a file can be omitted.

で、有利となる。Since the sheath 11 is made of a heat-resistant and slippery material, for example, a tube made of a fluororesin such as Teflon, the inner peripheral surface of the sheath 11 comes into contact with the probe 52 which is ultrasonically vibrated, and Even when frictional heat with the probe 52 is generated in the
There is no risk of melting. Therefore, the gap between the inner peripheral surface of the sheath 11 and the probe 52 that vibrates ultrasonically does not need to be set particularly large, so that the gap between the inner peripheral surface of the sheath 11 and the probe 52 is set relatively small. can do. As a result, the entire outer diameter of the sheath 11 can be reduced, which is advantageous in manufacturing a thin ultrasonic incision coagulation device.

Since the gap 60 having the predetermined constant interval L is formed, when the movable operation handle 32 is operated in the direction to close the fixed handle 31 side, the treatment section 41 of the probe 52 and the sheath 11
The living tissue is sandwiched between the peripheral portion of the distal end opening 59 of the narrowed portion 57 in the receiving member 56 at the distal end of the narrowed portion, and a part of the living tissue is part of the inner peripheral edge of the distal end opening 59 of the narrowed portion 58 and The rubbing can be performed in a state of being inserted into the gap 60 between the rubbing surface 54a of the side portion. Therefore, a gap 60 between the inner peripheral edge of the distal end opening 59 of the narrowed portion 58 and the rubbing surface 54 a on one side of the hook 54 is provided.
The living tissue inserted therein can be reliably coagulated.
