Bionic coupling anti-adhesion resistance-reducing high frequency electrotome electrode

Abstract

The invention discloses a bionic coupling anti-adhesion resistance-reducing high frequency electrotome electrode. The electrode is composed of an insulated electrotome handle and an electrode body, the upper surface of the electrode body and the lower surface of the electrode body are both provided with grid-shaped structures which are distributed uniformly, the grid-shaped structures are composed of transverse ridge strips and longitudinal ridge strips which are interwoven in the transverse direction and in the longitudinal direction, and the surface of the electrode boy is coated with a titanium dioxide coating. According to the bionic coupling anti-adhesion resistance-reducing high frequency electrotome electrode, the uniform grid-shaped structures are designed and processed on the upper and lower surfaces of the high frequency electrotome electrode, and therefore the carbonation adhesion of tissue in minimally invasive operation processes is effectively reduced; the titanium dioxide coating further reduces the adhesion of the tissue in the operation processes and strengthens the anti-adhesion and resistance-reducing effects of the grid structures; by the adoption of the grid-shaped structures, the tissue cannot be fully in contact with the surface of the electrode in the operation processes, and therefore the surface of the electrode is exposed to air more, the heat dissipation area is increased, and the burn of the tissue caused by high temperature electrodes is effectively reduced.

Description

technical field [0001] The invention relates to a new type of high-frequency electrosurgical electrode (also known as a high-frequency electrosurgical knife head) that can effectively reduce tissue adhesion and reduce surgical operation resistance during minimally invasive electrosurgery, and particularly relates to a bionic coupling anti-adhesion drop The utility model relates to a high-frequency resistance electrosurgical electrode, which belongs to the technical field of electrosurgical minimally invasive surgical instruments and instruments.

AI Technical Summary

Problems solved by technology

However, the above methods still have certain problems in the actual minimally invasive operation process: the scope of application is limited, and the anti-adhesive effect is general; some electrode surface coatings will volatilize harmful substances under high temperature, which poses a health threat to doctors and patients; Tissue contact area is too small for effective hemostasis and coagulation
