Frequency conversion high frequency electrotome

Abstract

Disclosed is a frequency conversion high frequency electrotome. The input port (1) is connected with the input end of an electrode plate detecting and alarming circuit (2). An output signal display module (4), a high frequency generator (6) and a frequency conversion adjusting module (7) are respectively connected with an automatic test markup language (ATML) processor (5), and the output end of the frequency conversion adjusting module (7) is connected with a pre-amplifier (8). The pre-amplifier (8) is connected with the input end of a first power amplifier (10), the output end of the first power amplifier (10) is connected with the input end of a second power amplifier (11), and the output end of the second power amplifier (11) is connected with an output interface (13). After the frequency demultiplication of the frequency conversion high frequency electrotome is carried out through a crystal oscillator, the fundamental frequency and the repetition frequency are obtained, and operating modes of pure cutting, mix cutting, monopole solidification, spraying solidification and double pole solidification are achieved. In a surgical operation, the cutting speed is fast, harm to a tissue is little, and separation and solidification of the tissue of a human body can be achieved, so that the aims of cutting and bleeding stop are achieved, and the utilization effect is good.

Description

technical field [0001] The invention relates to an electric knife, in particular to a variable-frequency high-frequency electric knife, which belongs to the technical field of medical instruments. 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 frequen...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the defects and deficiencies that most of the existing high-frequency electric scalpels cannot be converted or the range of frequency conversion is narrow, and the appropriate frequency cannot be selected according to the needs of the operation to realize the coagulation operation, it is inconvenient to use, and the cutting effect is not good. A compact structure, can produce five different frequencies and waveforms, and the output power can be adjusted according to needs, easy to use, good cutting effect frequency conversion high-frequency electric knife
