A kind of attracting electric knife pen

Abstract

The invention relates to the technical field of medical devices, in particular to a suction electric knife pen and a system thereof. Including cutter head, suction tube and installation assembly, the cutter head is set on the pipe wall of the suction tube; the installation assembly includes a shell, an insulating sleeve, the insulating sleeve is sleeved on the suction tube, and is arranged between the shell and the cutter head ; The electric knife pencil also includes an electric control unit and a conduction hose, the electric control unit is installed on the housing, and is in contact with the suction tube, and is suitable for controlling the magnitude of the current on the suction tube; the conduction hose is arranged between the suction tube and the knife The opposite end of the head is used to communicate with the suction pipe and the bellows; the shell is provided with an elastic part corresponding to the conduction hose, and the elastic part is suitable for squeezing the conduction hose under the action of external force. The suction electric knife pen of the present invention effectively solves the problem that the electric knife pen in the prior art adheres to the inner wall of the suction tube after inhaling large tissue or blood clots, resulting in blockage of the suction tube, and the handle end of the suction electric knife pen is more It is small and convenient for operation.

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 electrotome (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 the ...
