Definitions

  • the utility model relates to a medical device, in particular to a multifunctional electric cutter head used in a surgical procedure.
  • High-frequency electrosurgical knives are increasingly used in a variety of endoscopic procedures, such as laparoscopic, prostatectomy, gastroscope, cystoscopy, hysteroscopy and other operations. Because the high-frequency electrosurgical knife can simultaneously cut and coagulate, it is widely used in the surgery that the mechanical scalpel is difficult to enter and implement (such as abdominal tube ligation, prostatic urethral tumor resection). The high-frequency electrosurgical prominence of coagulation makes it widely used in diffuse oozing sites such as liver, spleen, thyroid, breast, and lung surgery.
  • High-frequency electric knives have two main modes of operation: unipolar and bipolar.
  • unipolar mode a complete circuit is used to cut and solidify the tissue, which consists of a high frequency generator in the high frequency electrosurgical unit, patient plates, connecting wires, and electrodes.
  • current is passed through the patient through active leads and electrodes, and the patient plate and its leads are returned to the generator of the high frequency electrosurgical unit.
  • the heating effect of a high-frequency electrosurgical knife that can destroy a diseased tissue is not caused by a heated electrode or a cutter head, like an electric cautery. It concentrates the high current density of high currents and directly destroys the tissue at a point in contact with the tip of the effective electrode. Coagulation occurs when the temperature of a tissue or cell that is in contact with or adjacent to an effective electrode rises to the protein in the cell. This precise surgical effect is caused by the waveform, voltage, current, type of tissue, and electrode. The shape and size are determined.
  • the most common configuration of the commonly used electrosurgical cutters is the "hook” electric cutter head usually provided in the shape of "L” or “J”, which can manipulate and lift the structure (hook) before cauterization, thereby It is possible to clearly show the need for surgery; there is also a “shovel”-shaped electric cutter head with a wide surface to burn a larger tissue area or a larger source of bleeding.
  • most surgeons require complete replacement of the electric cutter head to access the anatomical cutting surface organs and blood vessels to treat localized blood vessel bleeding, large area condensation, bloodless separation, and oscillating tissue and adhesion.
  • the replacement of the electric cutter head during surgery is potentially dangerous, delaying the treatment of the bleeding site, and adding a large amount of additional costs.
  • the utility model provides a multifunctional electric cutter head.

Brill E lectricity is produced when valence electrons are freed from atoms of conductive materials. When these electrons are set in motion in the same direction an electric current (I) is produced that is measured in amperes. Opposite charges on the ends of the conductor cause the elec-trons to flow in one direction toward the positive terminal. The differ-ence in potential between the positive and negative poles provides the electromotive force (voltage) to drive the current through the conductor (Figure 1).
