Abstract

A surgical operating apparatus comprises an insertion portion which has a distal end and a proximal end and which has a long axis and which is inserted into a body, a treatment portion which is disposed at the distal end of the insertion portion and which has a plurality of selectable surgical functions, an operation portion disposed at the proximal end of the insertion portion, a plurality of switches which are provided in the operation portion and which select the surgical functions, and a bulging portion which is disposed between the switches and which divides the switches and which doubles as a finger receiving portion.

Claims

1. A surgical operating apparatus comprising:

an insertion portion which has a distal end and a proximal end and which has a long axis and which is inserted into a body;

a treatment portion which is disposed at the distal end of the insertion portion and which has a plurality of selectable surgical functions;

an operation portion disposed at the proximal end of the insertion portion;

a plurality of switches which are provided in the operation portion and which select the surgical functions; and

a bulging portion which is disposed between the switches and which divides the switches and which doubles as a finger receiving portion.

2. The apparatus according to claim 1, wherein

the operation portion has, on a front side thereof, a switch attachment surface onto which the plurality of switches are attached,

the plurality of switches are arranged in a vertical direction of the switch attachment surface, and

the bulging portion has an extension which continuously extends from the switch attachment surface of the operation portion to both sides thereof.

3. The apparatus according to claim 1, wherein

the bulging portion is set so that the height of projection of this bulging portion from the switch attachment surface is larger than the height of projection of the plurality of switches from the attachment surface.

4. The apparatus according to claim 2, wherein

the operation portion has a main body of this operation portion and two handle elements to operate the treatment portion,

the two handle elements has a fixed handle element fixed to the main body of the operation portion and extending on a lateral side of the long axis, and a movable handle element supported to be openable/closable with respect to the fixed handle element, and

the attachment surface is provided at a junction between the main body of the operation portion and the fixed handle element.

5. The apparatus according to claim 4, wherein

the movable handle element has a thumb insertion ring portion into which a thumb is inserted,

the fixed handle element has a multiple finger insertion ring portion into which a plurality of fingers except for the thumb and index finger are inserted,

the switch attachment surface has a curving surface curving along a flow line on which the index finger moves in a condition where the thumb is inserted into the thumb insertion ring portion and the plurality of fingers except for the thumb and index finger are inserted into the multiple finger insertion ring portion.

6. The apparatus according to claim 5, wherein

the operation portion is set so that an angle α

between a tangent line of a front surface of the multiple finger insertion ring portion of the fixed handle element and a tangent line of a front surface of the switch attachment surface is larger than 90°

.

7. The apparatus according to claim 2, wherein

the main body of the operation portion has a switch unit in which two switches are integrated into one unit, and a concave unit receiver to which the switch unit is attached,

the switch unit has push buttons for the two switches, a flexible wiring line circuit board for the two switches, and a flexible base member in which the wiring line circuit board is embedded in insulating elastic members, and

the base member is attached to the unit receiver so that this base member curves along the curving surface.

8. The apparatus according to claim 7, wherein

the unit receiver has, in parts corresponding to the push buttons for the two switches, boss portions which receive force to push the push buttons for the two switches.

9. The apparatus according to claim 7, wherein

the two switches have a first switch which is disposed on the upper side of the switch attachment surface and which selects a frequently used first surgical function of the plurality of surgical functions, and a second switch which is disposed on the lower side of the switch attachment surface and which selects another second surgical function of the plurality of surgical functions.

10. The apparatus according to claim 9, wherein

the first surgical function is a function to simultaneously output an ultrasonic treatment output and a high-frequency treatment output, and

the second surgical function is a function to independently output the high-frequency treatment output alone.

11. The apparatus according to claim 9, wherein

the first surgical function is a function to output an ultrasonic treatment output in a maximum output state, and

the second surgical function is a function to output an ultrasonic treatment output in a preset arbitrary set output state lower than the maximum output state.

12. The apparatus according to claim 5, wherein

a finger pad portion formed of an elastic material is detachably attached to at least one of the thumb insertion ring portion and the multiple finger insertion ring portion.

13. The apparatus according to claim 5, wherein

the movable handle element has a finger hook in an upper portion of the thumb insertion ring portion.
