Problems solved by technology

[0004] Plasma surgical electrodes are mainly used to accurately cut and ablate tissue and to precisely stop bleeding during surgery. Since such devices are generally used on relatively small tissues or in minimally invasive surgery, the structure of existing plasma surgical electrodes is comparatively Fixed, or a vertical long rod, or a knife head with a fixed angle, when used in a complex and narrow surgical environment, the flexibility of the instrument is not enough, which will affect the operability and actual use effect of the operation

Abstract

The invention discloses a plasma operation electrode which comprises a handle, wherein the handle is connected with an electrode; the electrode comprises a loop pole; a work electrode is arranged at the tail end of the electrode; the work electrode and the loop pole are connected with a positive electrode and a negative electrode of a plasma generator separately; and a bending component is also arranged between the work electrode and the electrode and connected with a drive device. The plasma operation electrode has the advantages of being high in flexibility and wide in application range.

Description

technical field [0001] The invention relates to medical instruments, in particular to a plasma surgical electrode. Background technique [0002] The basic principle of the low-temperature plasma surgical electrode is to use the energy generated by the plasma generator to form a highly concentrated plasma thin layer between the plasma surgical electrode and the tissue. The plasma in the thin layer is accelerated by the electric field and has enough energy to crush it. The organic molecular chains in the tissue decompose the tissue into simple molecules, atoms or low molecular weight gases, so as to achieve the function of ablation and cutting. Since the current does not flow directly through the tissue, the tissue generates very little heat, so the treatment temperature is low (40-70°C), which can maintain the activity of the cells. At the same time, due to the insulating effect of the plasma and the thermal effect of the current, the blood vessels can be rapidly contracted ...
