COMPACT HAND HELD SWITCHING DEVICE WITH INSERTABLE SWITCHING MEANS

摘要

A surgical tool of the type in which cutting or cauterizing current is selectively introduced to a blade by means of a finger-operated switch actuating member, the tool comprised of an outer case and a correspondingly structured removable insert carrying the switching mechanism, the switch actuating arm between the switch actuating member and the switch mounted to reciprocate in a plane normal to the axis about which the switch actuating member oscillates to provide a compact pencil-type device, the combination case and insert being adaptable to provide switching means for applications other than surgical tools. The switches have threaded extensions which are inserted through trunnions in the casing and held there by clamping units.
