Abstract

The invention discloses a low-temperature plasma snare operation system and method. The system comprises an input unit, a control unit, an interface unit and a plasma unit, wherein the input unit receives a control instruction input by a user and sends the control instruction to the control unit; the control unit analyzes the control instruction and generates a first mode instruction when the control instruction indicates a first mode, calculates an output power used for the first mode according to a current impedance and the control instruction, and sends the first mode instruction and a first voltage indication associated with the output power to the interface unit; the interface unit transfers the first mode instruction and the first voltage indication to the plasma unit, and receives the current impedance of a target touch end from the plasma unit and sends the current impedance to the control unit; the plasma unit corresponds to receiving of the first mode instruction and the first voltage indication from the interface unit, and enters the first mode to conduct gasification trepanned resection on the target body based on radio frequency energy of the plasma.

Description

technical field [0001] The present invention relates to the field of radio frequency technology, and more specifically, relates to a low-temperature plasma snare knife operation system and method. 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...
