Problems solved by technology

The high-frequency transmission temperature is as high as 400-500 degrees. This temperature will accidentally injure the good tissues around the duodenal papilla, and is prone to complications such as pancreatitis (high mortality rate), bleeding, and perforation, which in turn increases the probability of bleeding problems. High, but also easy to damage pathological tissue
In this case, the doctor cannot perform the pathological analysis and it will cause trouble in the effective analysis of the section organization

Abstract

The invention discloses a low-temperature plasma incision knife operation system which comprises an input unit, a control unit, a connector unit and a plasma unit. The input unit is used for receivinga 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 thefirst mode instruction and the first voltage indication received from the connector unit and entering the first mode to perform vaporization cutting on a target body based on radio-frequency energy of a plasma.

Description

technical field [0001] The present invention relates to the technical field of radio frequency, and more particularly, relates to a low-temperature plasma incision knife operation system. Background technique [0002] High-frequency cutting electric knife is an electrosurgical instrument that replaces mechanical scalpel for tissue cutting. The working principle of the high-frequency cutting electric knife is to heat the tissue when the high-frequency high-voltage current generated by the effective electrode tip contacts the body, so as to realize the separation and coagulation of the body tissue, so as to achieve the purpose of cutting and hemostasis. The peak voltage of high-frequency cutting electrosurgical coagulation mode is larger than that of electric cutting mode. When high-frequency current passes through high-impedance tissues, it will generate heat in the tissues, causing the tissues to vaporize or coagulate, resulting in a good hemostatic effect, but at the same t...
