PURPOSE:To decrease the number of parts and to reduce the cost of production by providing an electrode pin for supplying a high-frequency current to a pair of gripping parts via a sheath integrally with a lock screw for fixing a stationary operating handle to the base end of this sheath. CONSTITUTION:A gripper is formed of an insertion part to be inserted into the coelon and a gripping part and operating part 4 disposed respectively in the front end and base end of this insertion part. The operating part 4 is adapted to open and close a pair of the gripping members in the gripping part and is constituted of the stationary operating handle 10 fixed by the lock screw 9 to the base end of the sheath 5 in the insertion part and a movable operating handle 12 mounted freely fixably by means of a screw 11 to this handle. The electrode pin 23 for supplying the high-frequency current to the respective gripping members is provided integrally with the lock screw 9. As a result, the number of parts is decreased and the cost of production is reduced. |
