Novel high-frequency electrotomy therapeutic apparatus

Abstract

The invention discloses a novel high-frequency electrotomy therapeutic apparatus. The therapeutic apparatus comprises a microprocessor with a built-in control circuit, a power generator, a high-frequency electrotome device, a negative plate, a power supply module and a plurality of interface circuit ends connected with external equipment, wherein the power generator is connected between the microprocessor and the high-frequency electrotome; the high-frequency electrotome device comprises an ultrasonic device and a variable frequency inverter; a power transmitter is also connected with the safety module; and the safety module comprises an automatic detection output frequency module. By adopting the scheme, the high-frequency electrotomy therapeutic apparatus can achieve the cutting aim, and has relatively high safety and low cost.

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.
