Low-temperature plasma incision knife operation system and method

Abstract

The invention discloses a low-temperature plasma incision knife operation system and method. The system includes an input unit, a control unit, an interface unit and a plasma unit; the input unit is used 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 sending the 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 is used for switching into the first pattern and conducting vaporization incision on a target object on the basis of the radio frequency energy of plasma as a response to the first pattern instruction and the firstvoltage 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, to a low-temperature plasma incision knife operation system and method. 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 sa...

AI Technical Summary

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
