Operation handles for electrocautery

摘要

An operation handle for electrocautery includes: a grip, an operation rod, a stopping part, a positioning bar, and a driven member. One end of the operation rod is jointly connected to the grip, and the other end has a pressing portion. The operation rod moves selectively from an initial position to at least one work position. The stopping part is disposed on the operation rod and adjacent to the pressing portion. The positioning bar is disposed on the grip and comprises at least one positioning groove. When the pressing portion of the operation rod is forced, the operation rod moves from the initial position to the at least one work position, and one end of the driven member is lodged in the at least one positioning groove.
