Description

technical field [0001] The invention relates to a medical device, in particular to a novel high-frequency electrosurgical treatment instrument. Background technique [0002] High-frequency electric knife, also known as high-frequency surgical device, is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. The high-frequency electric knife is composed of the host machine, the handle of the electric knife, the patient's pole plate, bipolar forceps, and a foot switch. The principle of high-frequency electric knife is to heat the tissue when the high-frequency and 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. At present, most domestic high-frequency electrosurgical units and imported high-frequency electrosurgical units have fixed frequencies, and use single-frequency sine waves and single-...

AI Technical Summary

Problems solved by technology

At present, most domestic high-frequency electrosurgical units and imported high-frequency electrosurgical units have fixed frequencies, and use single-frequency sine waves and single-frequency modulating wave transformations to complete various cutting and coagulation. The frequency cannot be adjusted according to actual needs, and the performance has not yet been achieved. Reaching the best is mainly reflected in the cutting speed of the electric knife, the speed of blood coagulation, and the size of tissue damage.

[0003] At the same time, the current safety requirements for high-frequency electrosurgical units are relatively high, which is mainly reflected in the control of its current. Therefore, although there are currently some solutions for control, safety accidents still occur frequently and are unreliable. These are controlled or detected. , is far from enough, and it is very difficult to control the high-frequency leakage current during use. If the leakage current is too high, the error exceeds a certain range and it will cause medical accidents.
