Surgical electric knife pen with replaceable electrode knife body

Abstract

The invention relates to the technical field of accessory devices of medical instrument, in particular to a surgical electric knife pen with a replaceable electrode. The surgical electric knife pen comprises an electrode knife body, a handle used for fixing the electrode knife body and can be controlled by hand, a PCB arranged in the handle and electrically connected with the electrode knife body and a button arranged on the handle and used for controlling the PCB in a point pressing mode, the electrode knife body is electrically connected with the PCB, a smoke suction pipe which penetrates from the end of the electrode knife body to the tail end and is used for collecting and sucking smoke generated during an operation, and the electrode knife body is a common electrode, a knife-tongue integrated electrode, a 30-60-degree bevel electrode or a telescopic electrode. The surgical electric knife pen structure can be switched according to different requirements of smoke suction and non-smoke suction, different surgery function requirements are met, rapid use in an surgery is facilitated, and the environment-friendly and healthy performance is better.

Description

technical field [0001] The invention relates to the technical field of medical device attachments, in particular to a surgical electric knife pen with replaceable electrodes. Background technique [0002] Surgical electric knife pen is a high-frequency electric knife that destroys diseased tissue through electric current. It is not caused by simply heating electrodes or knife heads. When the tissue under contact with the effective electrode or the temperature of the adjacent tissue or cell rises to denature the protein in the cell, coagulation will occur. This precise surgical effect is controlled by waveform, voltage, current, Depending on the type of tissue and the shape and size of the electrodes. [0003] The surgical electrosurgical pen used in routine surgery is equipped with common electrodes, and no smoking operation is performed. [0004] Smoke is often produced during certain surgical operations such as cutting blood coagulation, so some surgical electric knife p...

AI Technical Summary

Problems solved by technology

However, the existing surgical electrosurgical pen structure is either a scalpel with common electrodes or a conventional smoking surgical electrosurgical pen. There are no non-smoking common electrode surgical electrosurgical pens and smoking surgical electrosurgical pens that can be easily replaced, thus affecting the convenience of surgery. Fast to use and wastes smoking pipes
