Electro-surgical unit pencil apparatus and method therefor

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