Abstract

A surgical operating apparatus includes a sheath provided with a distal end part and a proximal end part, an apparatus main body to be coupled to the proximal end part of the sheath, a probe which is provided with a distal end part and a proximal end part, is inserted into the sheath, and transmits ultrasonic vibration from the proximal end part side to the distal end part side, a jaw which is turnably supported at the distal end part of the sheath, and is operated to be opened or closed between a closed position at which the jaw is engaged with the distal end part of the probe, and an opened position at which the jaw is separated from the distal end part of the probe, a handle which is provided in the apparatus main body, and operates the opening/closing operation of the jaw, a slider section which is provided in the apparatus main body, and is advanced/retreated to be moved in a central axis direction of the probe between a first movement position corresponding to the opened position of the jaw and a second movement position corresponding to the closed position of the jaw in accordance with the operation of the handle, and a notification mechanism for notifying of a state where the slider section has moved by an amount equal to or larger than a predetermined amount on the way thereof from the first movement position to the second movement position.

Claims

1. A surgical operating apparatus comprising:

a sheath provided with a distal end part and a proximal end part;

an apparatus main body to be coupled to the proximal end part of the sheath;

a probe which is provided with a distal end part and a proximal end part, is inserted into the sheath, and transmits ultrasonic vibration from the proximal end part side to the distal end part side;

a jaw which is turnably supported at the distal end part of the sheath, and is operated to be opened or closed between a closed position at which the jaw is engaged with the distal end part of the probe, and an opened position at which the jaw is separated from the distal end part of the probe;

a handle which is provided on the apparatus main body, and operates the opening/closing operation of the jaw;

a slider section which is provided in the apparatus main body, and is advanced/retreated to be moved in a central axis direction of the probe between a first movement position corresponding to the opened position of the jaw and a second movement position corresponding to the closed position of the jaw in accordance with the operation of the handle; and

a notification mechanism for notifying of a state where the slider section has moved by an amount equal to or larger than a predetermined amount on the way thereof from the first movement position to the second movement position.

2. The surgical operating apparatus according to claim 1, wherein

the notification mechanism includes a notification section which performs notification by means of at least one of a sound and a feeling of a click.

3. The surgical operating apparatus according to claim 2, wherein

the notification section includes

a cylindrical body that is fixed to the side of a guide member for guiding the movement of the slider section, and is provided with a step section on an outer circumferential surface at which a diameter thereof is changed at a position corresponding to the predetermined amount in a movement direction of the slider section, and

a leaf spring member that is provided with two end parts, one end part of which is fixed to the slider section, and the other end part of which is held on the outer circumferential surface of the cylindrical body in a state where the other end part is in sliding contact with the outer circumferential surface of the cylindrical body, and

at the time of the movement of the slider section, when the leaf spring member passes the step section, the other end part of the leaf spring member falls over the step section, and generates a knocking sound by knocking the circumferential wall surface on the lower side of the step section.

4. The surgical operating apparatus according to claim 2, wherein

the notification section includes a sound generation member which is provided on a guide surface for guiding the movement of the slider section when the slider section is moved, and generates a sound by being brought into contact with the slider section.

5. The surgical operating apparatus according to claim 1, wherein

the predetermined amount is set at a position corresponding to a operation amount of the handle, the operation amount enabling the appropriate ultrasonic treating capability to be exerted when the living tissue is grasped between the jaw and the distal end part of the probe.

6. The surgical operating apparatus according to claim 5, wherein

the ultrasonic treating capability is at least one of coagulation and incision.

7. A surgical operating apparatus comprising:

a sheath provided with a distal end part and a proximal end part;

an apparatus main body to be coupled to the proximal end part of the sheath;

a probe which is provided with a distal end part and a proximal end part, is inserted into the sheath, and transmits ultrasonic vibration from the proximal end part side to the distal end part side;

a jaw which is turnably supported at the distal end part of the sheath, and is operated to be opened or closed between a closed position at which the jaw is engaged with the distal end part of the probe, and an opened position at which the jaw is separated from the distal end part of the probe;

a handle which is provided on the apparatus main body, and operates the opening/closing operation of the jaw;

a slider section which is provided in the apparatus main body, and is advanced/retreated to be moved in a central axis direction of the probe between a first movement position corresponding to the opened position of the jaw and a second movement position corresponding to the closed position of the jaw in accordance with the operation of the handle; and

notification means for notifying of a state where the slider section has moved by an amount equal to or larger than a predetermined amount on the way thereof from the first movement position to the second movement position.
