ABSTRACT:
A bipolar coagulation forceps wherein the switch at the inner side of one of its legs can be closed by an actuator at the inner side of the other leg. The switch and the actuator have cooperating centering and guide elements which engage one another to prevent any shifting of the jaws at the working ends of the legs during that stage of pivoting of the legs when the jaws already engage each other but the pivoting of the legs relative to each other must continue in order to close the switch. The latter is connected with a terminal at the rear ends of the legs by a conductor which is confined in a tube at the inner side of the leg carrying the switch. The outer side of the leg which carries the actuator has a finger-receiving flute which enhances the flexibility of the respective leg and renders it possible to pivot the legs relative to each other subsequent to engagement of the jaws with one another.
