Description

Multifunctional electric knife head

Technical Field

The utility model relates to a medical instrument, in particular to a multifunctional electric knife head used in the operation process.

Background

High-frequency electric knives are increasingly used in various endoscopic operations, such as laparoscopy, prostatectomy, gastroscope, cystoscope, hysteroscope and the like. Because the high-frequency electric knife can cut and coagulate blood at the same time, the high-frequency electric knife is generally applied to operations which are difficult to enter and implement by a mechanical knife (such as abdominal duct ligation and prostate urethral lump excision). The coagulation effect of the high-frequency electrotome is outstanding, so that the high-frequency electrotome can be widely applied to diffuse blood seepage parts such as liver, spleen, thyroid, mammary gland and lung operations.

There are two main modes of operation of a high frequency electrotome, monopolar and bipolar. 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. The heating effect of a high-frequency electric knife capable of destroying diseased tissues is not caused by a heating electrode or a knife head, like an electric cautery. It collects the high-frequency current with high current density to directly destroy the tissue under the point of contact with the effective electrode tip. Coagulation occurs when the temperature of the tissue or cells in contact with or adjacent to the active electrode rises to denature proteins in the cells, the precise surgical effect being determined by the waveform, voltage, current, type of tissue and shape and size of the electrode.

The most common configuration of the electrosurgical blades of commonly used high-frequency electrotomes is a "hook" electrosurgical blade, usually provided in an "L" or "J" shape, which has the advantage of being able to manipulate and pull tissue (hook) prior to cauterization, thereby clearly revealing the surgical needs; there are also "spade" shaped electric bits that have a wider surface to cauterize a larger tissue area or a larger source of bleeding. Typically, during surgery, most surgeons need to completely replace the electrotome in order to access dissected cut surface organs and blood vessels to address local bleeding of blood vessels, large area coagulation, no blood separation and oscillating tissue and adhesions. However, replacing the electrical blade head during surgery is potentially dangerous, delaying the time to treat the bleeding site, and adding significant additional cost.
