Plasma scalpel and plasma operation system thereof

Abstract

The invention discloses a plasma scalpel and a plasma operation system. The plasma scalpel is of a multi-layer concentric structure and comprises an outer electrode, an insulating layer, an inner electrode, a reflecting layer and a grating optical fiber, wherein the multiple layers of the plasma scalpel are of a concentric rod-shaped structure, and a grating used for temperature sensing is etched on the grating optical fiber; the outer wall of the grating optical fiber is coated with the tubular inner electrode, the reflecting layer with low refractive index is arranged between the grating optical fiber and the inner electrode, the outer electrode is arranged on the outer wall of the inner electrode, the insulating layer is arranged between the inner electrode and the outer electrode, the distance from the axis of an optical fiber grating to the end surface of the inner electrode is less than 5mm, and the length of the end part of the inner electrode extending out of the insulating layer is 2-5mm. Compared with a unipolar plasma scalpel, a bipolar plasma scalpel has a more obvious restraining effect on an electric field, plasmas can be concentrated in a smaller area, operation injury can be avoided as far as possible, the operation success rate can be enhanced, pain of a patient can be reduced, and therefore the operation is more suitable for fine operations.

Description

technical field [0001] The invention relates to the field technology of a plasma scalpel and a plasma plasma surgery system thereof, in particular to a plasma scalpel and a plasma surgery system thereof. Background technique [0002] At present, the ion scalpel and its plasma plasma surgery system on the market are generally not practical enough. Most plasma scalpels lack temperature measurement and impedance measurement. Excessive temperature in the affected area during plasma surgery may cause additional damage to the patient. The center of medical high-temperature plasma The temperature can reach 150°, and the low-temperature plasma can reach up to 70°. Plasma minimally invasive surgery must strictly control the range of the heating area; no matter what kind of plasma knife, human tissue needs to participate in the radio frequency current circuit, so the human body or local area The impedance of the human body tissue will also affect the magnitude of the radio frequency c...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies of the above-mentioned technologies, the purpose of the present invention is to provide a plasma scalpel and its plasma surgery system, which aims to solve the problem that there is no temperature measurement and impedance measurement in other existing equipment on the market, which is easy to cause additional damage.
