Abstract

The invention discloses a high-frequency endoscopic surgical electrode, which comprises an electrode body, an outer sheath, a fixing sleeve component and a handle. The electrode body with a near end and a far end comprises a curved section at the far end and a straight section at the near end, the far end of the curved section is provided with two electrode heads arranged at an interval, and the two electrode heads and a middle insulating layer jointly form an arc face. The outer sheath is in a hollow tubular shape, and a far end of the outer sheath is open and in smooth transition. The electrode body is penetratingly arranged in the outer sheath, and the curved section at the far end of the electrode body is capable of smoothly extending and retracting in the opening of the far end of theouter sheath. The high-frequency endoscopic surgical electrode is beneficial for a doctor to clearly see conditions of a zone of action and is capable of relatively increasing the area of contact with a target tissue to prevent the electrode head from scraping the tissue, so that functions of blood coagulation and ablation are realized, and operation time is shortened while operating efficiency can be improved.

Description

technical field

[0001] The invention relates to the technical field of medical instruments, in particular to a high-frequency endoscopic surgical electrode. Background technique

[0002] High-frequency endoscopic surgical electrodes are high-frequency electrodes used to complete surgical operations under endoscopes, and belong to the application part of high-frequency surgical equipment; under endoscopic surgery, they enter through endoscopic instrument channels or other instrument channels Human body, used for routine ablation, coagulation, etc. of human tissue. Its working principle is: two electrodes are assembled on the same support, when the high-frequency surgical equipment outputs a high-frequency current with a certain waveform, the high-frequency current flows between the two electrodes and directly acts on the human body. Both the working electrode and the return electrode are at the electrode tip, one end is the working electrode, and the other end is the return ...
