Problems solved by technology
[0002] Nowadays, there are more and more medical applications of targeted knife in the treatment of cancer tumors. However, during the operation, there may be adhesion between the cell tissue and the knife surface, which makes it inconvenient to pull out the knife or brings out the cell tissue, which is not conducive to the normal operation. Therefore, it is necessary to solve the above problems through special treatment of the knife surface

Embodiment Construction
[0012] In the method of preventing the adhesion of the targeted knife surface of the present invention, firstly, the knife surface is smoothed, and then the NaCl crystal is evenly sprayed on the knife in a molten state (melting point 801 degrees) with high-temperature nano-spraying equipment (many such equipment are available in the market). On the surface, nano-spraying is applied to reduce the resistance after spraying, and attention should be paid to prevent crystal regeneration during cooling and increase surface roughness, and the crystal regeneration temperature should be exceeded. Because the surface of the knife is coated with NaCl, when the targeted knife is inserted into the tissue, NaCl will melt slowly, increasing the concentration of the tissue fluid around the knife surface to dehydrate the cells, so that there is enough liquid around the knife surface to isolate the knife surface from the cells, and then Performing cryosurgery does not allow the knife surface to ...

The invention relates to a targeted knife anti-adhesion method comprising the following steps: cleaning and smoothing the targeted knife face; using high temperature nanometer spraying equipment to evenly spray NaCl crystal onto the knife face under a fusion state; allowing the NaCl crystal on the knife face to slowly melt when the targeted knife inserts the tissue, thus increasing the knife face surrounding cell interstitial fluid concentration, dehydrating the cells, and isolating the knife face from the cells. The knife face is coated with NaCl; the NaCl can slowly melt when the targeted knife inserts the tissue, thus increasing the knife face surrounding cell interstitial fluid concentration, dehydrating the cells, providing sufficient liquid around the knife face, and isolating the knife face from the cells; the Cryosurgery can be then carried out without enabling the knife face to directly make contacts with the cells, thus solving the knife face and organ adhesion problems.
Description
technical field [0001] The invention relates to a targeted knife for medical equipment, in particular to an anti-adhesion method for the knife surface of a targeted knife. Background technique [0002] Nowadays, there are more and more medical applications of targeted knife in the treatment of cancer tumors. However, during the operation, there may be adhesion between the cell tissue and the knife surface, which makes it inconvenient to pull out the knife or brings out the cell tissue, which is not conducive to the normal operation. Therefore, it is necessary to solve the above problems through special treatment of the knife face. Contents of the invention [0003] The object of the present invention is to solve the above problems, and provide a targeted anti-adhesion method for the knife surface. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a method for preventing the adhesion of the targeting knife, at first,...
