Electro-surgical unit pencil apparatus and method therefor
First Claim
1. A combined electro-surgical unit (ESU) pencil apparatus comprising, in combination:
- a removable elongated shroud, adaptably fitted over an external surface of an electro-surgical unit pencil, said pencil having electro-surgical means located within a portion of said shroud and electro-surgical tip means that can extend beyond an opening located at a distal end of said shroud for use in surgery, wherein said shroud comprises a conduit having an open proximal end, said open distal end, and a generally semi-circular shaped hollow interior and a receiving surface located on an external top surface of said conduit for receiving the electro-surgical unit pencil;
external conduit means coupled to said open proximal end of said elongated shroud for exhausting smoke located within said shroud; and
smoke evacuation means coupled to said external conduit means for exhausting smoke passing from said shroud into said external conduit means.

Abstract
An electro-surgical unit (ESU) pencil apparatus is disclosed in which an improved handpiece enables the surgeon to vary the length of working electrode without having to use cutting electrodes of varying lengths. This is achieved by installing the electrode in an assembly that may, as desired by the surgeon, be extended from, or retracted into, the body of the ESU pencil apparatus. Means are provided for supplying uninterrupted RF supply to the electrode tip and uninterrupted smoke evacuation for the ESU pencil apparatus as the electrode assembly is expanded or retracted. Additionally, means are provided for locking the electrode assembly at the desired length, so that it does not move during the operation. The ESU pencil apparatus is also adapted for use with an ESU-argon beam coagulator pencil.
