Description
Technical Field
The utility model belongs to electricity congeals the sword field, especially relates to a have cigarette accuse electricity congeals sword.
Background
An electrocoagulator high frequency electrotome (high frequency surgical instrument) is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. The tissue is heated when the high-frequency high-voltage current generated by the tip of the effective electrode contacts with the body, so that the separation and coagulation of the body tissue are realized, and the purposes of cutting and hemostasis are achieved. High frequency electric knives have been used in clinic for over 70 years since 1920. It is changed by four generations from spark plug discharge-high power electron tube-high power transistor-high power MOS tube. With the popularization, application and development of computer technology, at present, a high-performance single chip microcomputer is widely applied to complete machine control of a high-frequency electrotome, and automatic regulation of power waveforms, voltages and currents under various functions, detection of various safety indexes, programmed control and detection and indication of faults are implemented. Therefore, the safety and the reliability of the equipment are greatly improved, and the operation process of a doctor is simplified.
Meanwhile, with the development of medical technology and the requirements of clinical application, the composite electrosurgical equipment mainly including the high-frequency surgical instrument has been developed correspondingly: the high-frequency argon air knife, the high-frequency ultrasonic operation system, the high-frequency electric cutting endoscope treatment system, the high-frequency rotary cutting defatting machine and other devices have obvious clinical effects. The derived accessories special for various high-frequency surgical instruments (such as the bipolar electric scissors, the bipolar electric resectoscope, the vaporizing roller electrode of the electric resectoscope and the like) also develop a wider application range for clinical operations.
There are two main modes of operation of high frequency electrotomes: unipolar and bipolar.
Unipolar mode: in monopolar mode, the tissue is cut and coagulated with a complete electrical circuit consisting of the high frequency generator, the patient plate, the connecting leads and the electrodes in the high frequency knife. In most applications, the current passes through the patient via the active lead and electrode, and is returned to the generator of the high frequency knife by the patient plate and its lead.
Bipolar mode: the bipolar coagulation is to supply high-frequency electric energy to body tissues through two tips of bipolar forceps so as to dehydrate and coagulate blood vessels between two ends of the bipolar forceps, thereby achieving the purpose of hemostasis. The application range of the forceps is limited between two ends of the forceps, the degree of damage and the influence range to body tissues are far smaller than those of a monopolar mode, and the forceps are suitable for sealing small blood vessels (the diameter is less than 4 mm) and fallopian tubes. Therefore, bipolar coagulation is often used in more delicate operations such as brain surgery, microsurgery, ophthalmology, gynecology and obstetrics, and hand surgery. The safety of bipolar electrocoagulation is being increasingly recognized and the range of applications is expanding.
The disposal of surgical smoke is becoming more and more appreciated because of the great hazard of surgical smoke. Foreign studies indicate that the surgical smoke contains more than 600 chemical components, wherein CO and acrylonitrile are most concerned, and long-term inhalation by workers can cause headache, dizziness, nausea, cough, asthma and the like. If the operation smoke is not discharged in a closed manner in time, the toxic substances are absorbed by the blood in the abdominal cavity, and the body of the patient is damaged. 95% of smoke generated by electrotome equipment is aerosol with the particle size of less than 5 mu m, the deposition distribution of aerosol particles in human respiratory organs is related to the particle size of the aerosol particles, larger particles are deposited in respiratory tracts, and the particles with the particle size of 0.5-5.0 mu m can directly invade alveoli.
The traditional electrocoagulation knife has the disadvantages that the sight of medical staff is unclear due to the fact that smoke generated by cutting cannot be discharged in time in clinical operation, so that troubles are caused to the medical staff, different operation requirements are met, different electrocoagulation knife heads need to be used, and the work of the medical staff is slightly troubled.
