ABSTRACT:
A novel handpiece for use with electrosurgical equipment and adapted to receive a disposable scalpel blade having an elongated insulated handle having first and second ends with its second end having an opening to the handle interior, an insulated electrical wire coupled to the first end of the handle, an electrically conductive structure mounted within the handle at its second end and electrically connected to the wire, the structure including within the handle an elongated metal part having adjacent the handle second end a collet and having further removed from the second end an externally-threaded portion, the handle at its second end having a separable portion having on its interior an internally-threaded portion and configured such that the latter threadingly engages the externally threaded portion and when so engaged and rotated in one direction engages and tightens up on the collet, and when rotated in the opposite direction loosens up on the collet, the collet being constructed to receive and firmly hold a scalpel blade inserted therein by its flat side when the separable handle portion is rotated in one direction, the separable handle portion being configured to receive and surround the non-sharpened end of the scalpel blade so that the latter may be inserted into the collet on its interior through the opening at the handle second end.
