Problems solved by technology

[0003] The cutting knife is used in different situations, and the size of the blade is also different. The blade of the existing cutting knife cannot be replaced, which is a waste of resources and has great limitations. In addition, the existing cutting knife cannot be lubricated during cutting, which is easy to cause tissue adhesion , cutting can not be sterilized at the same time, causing other tissues to be easily contaminated. Therefore, we propose a convenient pathology knife to solve the above problems
