Suction electrotome pen

Abstract

The invention relates to the technical field of medical instruments, in particular to a suction electrotome pen and a system thereof. The suction electrotome pen comprises an electrotome head, a suction tube and a mounting assembly, and the electrotome head is arranged on the tube wall of the suction tube; the mounting assembly comprises a shell and an insulating sleeve, and the insulating sleeve is arranged on the suction tube in a sleeving mode and arranged between the shell and the electrotome head. The electrotome pen further comprises an electric control unit and a conducting hose, and the electric control unit is installed on the shell, makes contact with the suction tube and is suitable for controlling the magnitude of current on the suction tube. The conducting hose is arranged at one end, opposite to the electrotome head, of the suction tube so as to communicate the suction tube with the corrugated tube; the shell is provided with an elastic part, the elastic part corresponds to the conducting hose, and the elastic part is suitable for extruding the conducting hose under the action of external force. The suction electrotome pen effectively solves the problem that the suction tube is blocked due to the fact in the prior art that large tissue or blood clots and the like are attached to the inner wall of the suction tube after the electrotome pen sucks the large tissue or blood clots and the like, the handle end of the suction electrotome pen is smaller, and surgical operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a suction electric knife pen. Background technique [0002] High-frequency electric knife (high-frequency surgical device) is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency high-voltage current generated by the effective electrode tip contacts the human body, and realizes the separation and coagulation of the tissue, thereby achieving the purpose of cutting and hemostasis. [0003] In the process of using an electrosurgical pen for surgery, it is usually accompanied by cauterization and carbonization of the patient's tissue, as well as the gasification of the patient's body fluid and blood. These high-temperature processes generate large volumes of surgical fumes. [0004] On the one hand, surgical smoke will reduce the clarity of the surgeon's view of the patient's tissue, affecting t...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a suction electric knife pen to solve the problem that the electric knife pen in the prior art is easy to inhale large pieces of tissue or blood clots during the suction process, which leads to the blockage of the suction tube of the electric knife pen
