Low-temperature plasma stripping cutter operation system and method

Abstract

The invention discloses a low-temperature plasma stripping cutter operation system and method. The system includes an input unit, a control unit, an interface unit and a plasma unit; the input unit isused for receiving a control instruction input by a user and sending the control instruction to the control unit; the control unit is used for parsing the control instruction, generating a first pattern instruction when the control instruction indicates a first pattern, calculating the output power under the first pattern according to the current impedance and the control instruction and sendingthe first pattern instruction and a first voltage indication correlated with the output power to the interface unit; the interface unit is used for transmitting the first pattern instruction and the first voltage indication to the plasma unit, receiving current impedance of a target contact end from the plasma unit and sending the current impedance to the control unit; the plasma unit switches into the first pattern and conducts vaporization stripping on a target object on the basis of the radio frequency energy of plasma as a response to the first pattern instruction and the first voltage indication which are received from the interface unit.

Description

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