Problems solved by technology

Laparoscopic tissue cutting and hemostasis are very important for laparoscopic surgery. However, the high-frequency electrotome used in the past has poor hemostatic function, and the thermal effect caused great damage to tissues and organs, and the generation of smoke has made laparoscopic surgery further developed. restricted

Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing:

[0034] Such as figure 1 , a high-frequency electrosurgical workstation, including stm32 microprocessor, peripheral equipment interface adapter, waveform generator, audio amplifier circuit, current sampling, voltage sampling and power supply circuit. The voltage sampling circuit and current sampling circuit are connected to the microprocessor through an analog-to-digital converter, the hand control and foot control signals are connected to the microprocessor through an isolation circuit, and the waveform generator inside the microprocessor generates a radio frequency signal, which passes through the gate The driver is connected to the radio frequency power amplifier, and the audio signal output by the microprocessor is sent to the audio amplifier circuit. The digital-to-analog converter 1 outputs a DC voltage of 0-5V to control the high-voltage power supply, and the DC volt...

Abstract

A high-frequency electrosurgical station applicable to surgeries and worthy of popularization is a special high-power high frequency generator. The high-frequency electrosurgical station generates high frequency current of specific frequency, waveform and load power curves; the high frequency current directly acts on the surface of biological tissues and centrally heats the tissues to volatilize tissue elements, and accordingly physical effects such as cutting and hemostasis are achieved. Through high-frequency power output by a main unit of the high-frequency electrosurgical station and jaw pressure of vessel forceps, collagen and fibrous protein in human tissues fuse and degenerate, walls of blood vessels fuse into a transparent tape, and permanent luminal closure is achieved. In open surgery or endoscopic surgery, a vessel closure cutting system can be given to full play for any vein, artery or tissue-bundle, smaller than 7mm in diameter, and closing or cutting is safer, faster or more convenient. The above advantages are hardly found in ultracision harmonic scalpels and bipolar coagulation. The high-frequency electrosurgical station has the functions of unipolar incision, unipolar coagulation, bipolar coagulation, bipolar incision, large vessel close-cutting and the like and is a necessity for operating rooms in future.

Description

technical field [0001] The present invention relates to a medical instrument, especially a medical instrument for surgical operation, specifically a high-frequency electrosurgical workstation. Background technique [0002] High-frequency electrosurgical surgery has been used in surgical practice for more than eighty years. In recent years, with the development of science and technology, high-frequency electrosurgical equipment has tended to have a special automatic control system with microprocessor and electronic sensor technology to realize automation. The development of high-frequency electric knife has become a representative device among electronic instruments used in surgery, and an indispensable tool in modern surgery. [0003] Urinary and gastrointestinal surgery has traditionally had to be performed with the abdominal cavity open. Using electrosurgical technology, high-frequency current can be applied to the surgical site through electrodes introduced into the ure...
