Low-temperature plasma trapping cutter operation equipment

Abstract

The invention discloses low-temperature plasm trapping cutter operation equipment. The equipment incudes a liquid infusion unit, a bipolar electrode socket connector, an emitting electrode and a circuit electrode; the liquid infusion unit responds to an liquid infusion signal and infuses a target object with liquid to form a membrane serving as a conducting medium between the emitting electrode and the circuit 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 emitting electrode receives the first input voltage generated by the high frequency generator through the bipolar electrode socket connector to release first voltage between the emitting electrode and the circuit electrode so that the conducting medium can reach first temperature and be driven to be converted into a plasma layer; therefore, plasma is generated by utilizing electric energy to stimulate the conducting medium, and trapping incision is conducted on the target object in a vaporized mode on the basis of the radio frequency energy of the plasma; the circuit electrode and the emitting electrode are introduced through a same conduit and form a conductive circuit in the target object.

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...
