Abstract

The invention discloses a low-temperature plasma circular sleeve knife operation device which comprises a liquid input unit, a bipolar electrode socket connector, a transmitting electrode and a loop electrode. The liquid input unit is used for responding to a liquid input signal, inputting liquid to a target body to form a thin layer of a conducting medium between the transmitting electrode and the loop electrode, the bipolar electrode socket connector is connected with a high-frequency generator through a high-frequency connecting line and used for receiving first input voltage generated by the high-frequency generator, the transmitting electrode applies first voltage between the transmitting electrode and the loop electrode through the first input voltage generated by the high-frequencygenerator received by the bipolar electrode socket connector, so that the conducting medium reaches first temperature and facilitates the conducting medium to be converted to a plasma layer, so that electric energy excites the conducting medium to generate plasmas, vaporization circular sleeve cutting of the target body is implemented by radiofrequency energy based on a plasma, and the loop electrode and the transmitting electrode are led in through the same catheter to form a conducting 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...
