Abstract

The invention discloses a low-temperature plasma stripping knife operation system which comprises an input unit, a control unit, a connector unit and a plasma unit. The input unit is used for receiving a control instruction inputted by a user and transmitting the control instruction to the control unit, the control unit is used for analyzing the control instruction, generating a first mode instruction when the control instruction indicates a first mode, calculating output power for the first mode according to current impedance and the control instruction and transmitting the first mode instruction and a first voltage instruction associated with the output power to the connector unit, the connector unit is used for forwarding the first mode instruction and the first voltage instruction to the plasma unit and receiving current impedance of a target contact end from the plasma unit and transmitting the current impedance to the control unit, and the plasma unit is used for responding to the first mode instruction and the first voltage indication received from the connector unit and entering the first mode to perform vaporization stripping on a target body based on radio-frequency energy of a 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 stripping knife operation system. Background technique [0002] With the continuous development of digestive endoscopy technology, endoscopic treatment of gastrointestinal diseases is becoming more and more popular. Endoscopic submucosal dissection is used to treat early-stage gastrointestinal cancer, so that more gastrointestinal lesions can be completely resected under endoscopy at one time. 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 electrosurgical dissection is an electrosurgical instrument that replaces mechanical scalpels for tissue dissection. The working principle of the high-frequency stripping electrotome is to heat the tissue when the high-frequency high-voltage cu...
