Electrocoagulation cutter

Abstract

The invention discloses an electrocoagulation cutter. The electrocoagulation cutter comprises a handle, a metal pipe, a functional pipe, a washing pipe, a transition pipe, a power line and a pipe switch; a cavity is formed in the handle; the metal pipe is used for providing a channel for fluid; a cutter head mounting position is arranged at the front end of the metal pipe; the functional pipe covers the exterior of the metal pipe in a sleeving mode; the functional pipe can conduct reciprocating motion in the axial direction relative to the metal pipe, and when the functional pipe moves towardthe front end of the metal pipe, the cutter head mounting position can be covered; the washing pipe is communicated with the metal pipe; the transition pipe is communicated with the metal pipe; the power line is connected with the metal pipe and used for transmitting electric signals of electrocoagulation or cutting to a cutter head in the cutter head mounting position; the pipe switch is used forturning on or turning off the washing pipe or the channel between the transition pipe and the metal pipe. Electrocoagulation or cutting work and washing or absorbing work on a targeted area can be achieved through signal stimulation of the power line, and the operation performance of the electrocoagulation cutter is improved.

Description
