ABSTRACT:
A generally flat insulator chuck is arranged to retain surgical electrodes so that the working area of the electrodes extends externally on one end and an electrical circuit accomodating prong is contained within a recessed chamber at the other end. The recessed chamber is dimensioned so as to effect continuous contouring relative to a receiving control handle apparatus in such a manner that the physical stress is translated between the insulator sidewalls of the chuck and the insulator of an extended plug on the handle. The electrical connection extension prong within the recess slidingly engages an electrical connector embedded within the handle extension so as to provide electrical contact free of physical stress from usage. Locking and guiding arrangements cooperate between the handle and the chuck to further insure firm attachment.
