Abstract

A surgical operating apparatus which includes a sheath with a distal end and a proximal end, an apparatus main body to be coupled to the proximal end of the sheath, a probe which is inserted through the sheath and which transmits ultrasonic waves, a probe distal end provided at the distal end of the probe, a jaw which is pivotally supported at the distal end of the sheath and which is geared with the distal end of the probe, a fixed handle provided in the apparatus main body, and a movable handle which is swingable with respect to the fixed handle and which operates the jaw in a direction to be in and out of contact with the distal end of the probe by a swing operation, the surgical operating apparatus includes a switch portion which is provided in the fixed handle and which controls a treatment of a living tissue, a switch holding portion which is provided in the fixed handle and which holds the switch, and a pressing member which fixes the switch portion in a state pressed against the switch holding portion.

Claims

1. A surgical operating apparatus which includes:

a sheath with a distal end and a proximal end;

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

a probe which is inserted through the sheath and which transmits ultrasonic waves;

a probe distal end provided at the distal end of the probe;

a jaw which is pivotally supported at the distal end of the sheath and which is geared with the distal end of the probe;

a fixed handle provided in the apparatus main body; and

a movable handle which is swingable with respect to the fixed handle and which operates the jaw in a direction to be in and out of contact with the distal end of the probe by a swing operation,

the surgical operating apparatus comprising;

a switch portion which is provided in the fixed handle and which controls a treatment of a living tissue;

a switch holding portion which is provided in the fixed handle and which holds the switch; and

a pressing member which fixes the switch portion in a state pressed against the switch holding portion.

2. The apparatus according to claim 1, wherein

the switch holding portion has a switch mounting hole portion provided in the fixed handle, and a switch receiving portion provided in the peripheral edge part of an opening of the switch mounting hole portion,

the switch portion has a flat-plate-shaped switch support formed of an elastic body, and a switch main body mounted on the switch support, and

the pressing member has a pressing portion which presses the switch support from the inner side of the switch mounting hole portion so that the switch support is in pressure contact with the switch receiving portion.
