Precautions for use
1, surgical blades need to be sterilized every time they are used, and any one of them can be sterilized by high-pressure steam, boiling or soaking. The effect of boiling sterilization is very obvious, but it is recommended to use disposable medical surgical blades.
2, no matter what kind of knife method, should be perpendicular to the tissue with the protruding surface of the blade, cut the tissue layer by layer, don't use the tip of the knife to operate hard, hold the knife too high to control instability, too low and hinder the line of sight, and be moderate.
3. Doctors who operate with scalpels for a long time often have discomfort such as wrist fatigue, which leads to wrist strain. Therefore, it may adversely affect the surgical effect and bring health risks to the doctor's wrist.
4. When cutting muscles and other tissues, blood vessels are often accidentally injured. In this case, it is necessary to rinse with clear water to find the bleeding point as soon as possible, otherwise it will cause serious difficulties for normal operation.
