Problems solved by technology

When the high-temperature surgical knife comes into contact with soft tissue, it will produce blood coagulation and cutting effects. However, the laser surgical knife head adopts the method of laser conversion of heat energy. Due to uneven heat distribution during surgical cutting, there may be adhesion problems to the tissue, which is easy to Cause additional tissue trauma, tear bleeding, burns, etc.
Existing scalpels used in laser surgery systems tend to stick to tissues during use, are easy to wear, and are damaged quickly during work. Once the blade is worn out, the scalpel needs to be replaced, resulting in a waste of resources. If the blade is damaged and cannot be replaced immediately, it will affect the operation process and reduce the operation efficiency

Abstract

The invention relates to a preparation method and application of an anti-adhesion scalpel head coating for a laser surgery system. The preparation method includes the steps of: coating an oxidant manganese dioxide layer on the scalpel head, and then vacuum-coating a multi-layer aluminum oxide layer, each layer The thickness of the aluminum oxide layer is 200-600nm; where the manganese dioxide layer is coated on the scalpel head, including steps: the scalpel head is ultrasonically cleaned with absolute ethanol and deionized water for 5-10min, and then immersed in an aqueous solution of manganese chloride Put it aside for 2-3 hours, take it out and wash it and dry it; then soak it in stearic acid ethanol solution, let it stand for 3-6 hours, take it out, rinse it with absolute ethanol, and dry it at 60-80°C for 1-2 hours. The scalpel tip prepared by the preparation method of the scalpel tip coating provided by the present invention can realize functions such as rapid cutting without sticking when in contact with tissue, and the effect does not deteriorate after repeated use for many times, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a preparation method and application of an anti-adhesion scalpel coating for a laser surgery system. Background technique [0002] Medical scalpel is a necessary medical instrument in various operations. Its main function is a special knife for cutting human or animal tissues. It is an indispensable and important tool in surgical operations. A large amount of heat energy is generated during laser surgery, which makes surgical knives very hot. When the high-temperature surgical knife comes into contact with soft tissue, it will produce blood coagulation and cutting effects. However, the laser surgical head adopts the method of laser conversion of heat energy. Due to the uneven distribution of heat during surgical cutting, there may be adhesion problems to the tissue, and it is easy to Cause additional tissue trauma, tear bleeding, burns, etc. Existing scalpels used in la...
