A Surgical Electrode for Radio Frequency and Low Temperature Plasma

Abstract

The invention provides a surgical electrode and system for radio frequency and low temperature plasma, which are used for ablation and coagulation during surgery. The surgical electrode includes an electrode, a guide tube, a telescopic handle and a circuit unit, wherein there are three electrodes, including an electrode head , the insulating layer and the electrode wire, in addition to the symmetrically arranged double electrodes, also includes a hollow cylindrical third electrode arranged outside the insulating layer. The surgical electrode system includes a surgical electrode, a control module, and an output module. The three electrodes are connected in series or Parallel connection can effectively combine the benefits of the two modes of radiofrequency coagulation and low-temperature plasma ablation into a single device. Operating habits, and save the cost of surgery.

Description

A Surgical Electrode for Radio Frequency and Low Temperature Plasma technical field The present invention relates to the field of medical instruments, is a kind of active medical instrument for operation, specifically relates to a The radio frequency and low temperature plasma surgical electrodes used in conjunction with the radio frequency plasma surgery host, including three electrode heads, which can be used for hand Intraoperative ablation and coagulation. Background technique It is generally under the endoscope at present that the radio frequency electrode is used for coagulation, and the plasma electrode is used for these 2 kinds of ablation respectively. Separate operation methods, RF electrodes and plasma electrodes still need to be used with different electrosurgical equipment. For example, low-temperature plasma equipment can only support plasma electrodes for surface ablation, and radio frequency equipment can only support low-power electrodes. Do blood ...

Problems solved by technology

Although there are also many called "radio frequency plasma electrodes", different electrodes, that is, between radio frequency electrodes and plasma electrodes, still need to be replaced. During the operation, frequent replacement of electrodes not only prolongs the operation time, but also increases the patient's treatment. cost

[0003] In the current electrode products on the market, the electrode heads are usually two symmetrical bean-shaped electrode heads separated by a small gap in the middle. This electrode is only suitable for small-scale blood coagulation and ablation, and its clinical application is still relatively limited; The electrode tip can only generate a small energy current. During hemostasis and ablation, the small current has a narrow and shallow effect on the operation site, which further prolongs the operation time and increases the pain of the patient; but when the electrode releases a large energy, a On the one hand, it will break down the isolation insulating layer between the two electrodes, the ionosphere cannot be generated and the function of plasma ablation cannot be realized, and the energy cannot be released, and the energy is too large to cause short circuit of the electrodes, and even cause the electrode to fall into the human body harm

On the other hand, the high temperature generated by the electrode head will not only adhere to biological tissues, but also cause side effects caused by tissue damage such as tissue necrosis and degeneration after surgery.
