Abstract

The invention discloses a low-temperature plasma snare knife surgical apparatus comprising a liquid input unit for inputting, in response to a liquid input signal, a liquid into a target body to forma thin layer of a conductive medium between an emitter electrode and a loop electrode; a bipolar electrode socket connector connected to a high-frequency generator through a high-frequency connectionline and used for receiving a first input voltage generated by the high-frequency generator; the emitter electrode receiving the first input voltage generated by the high-frequency generator via the bipolar electrode socket connector, applying a first voltage between the emitter electrode and the loop electrode such that the conductive medium reaches a first temperature and is converted into a plasma layer, thereby exciting the conductive medium with electrical energy to generate a plasma, and vaporizing and snare cutting the target body based on the RF energy of the plasma; and the loop electrode introduced through the same conduit as the emitter electrode and forming a conductive loop in the target body.

Description

technical field [0001] The present invention relates to the field of radio frequency technology, and more particularly, relates to a low-temperature plasma snare knife operation equipment. Background technique [0002] With the continuous development of digestive endoscopy technology, the endoscopic treatment of gastrointestinal diseases is becoming more and more popular. The electric snare knife is used in conjunction with the endoscope to remove polyps or other redundant tissues in the digestive tract by using high-frequency current. It can avoid the risk of traditional surgical treatment, and has the characteristics of small trauma, good curative effect, and high surgical technical requirements. [0003] High-frequency snare cutting electrotome is an electrosurgical instrument that replaces mechanical scalpel for tissue snare cutting. The working principle of the high-frequency snare cutting electrosurgical knife is to heat the tissue when the high-frequency high-voltage...
