[0002] Soft tissue refers to the subcutaneous tissue, muscles, tendons, ligaments, joint capsules, synovial capsules, nerves, blood vessels, etc. Soft tissue is a relatively important human tissue. Soft tissue cutting tools are medical devices used to cut human soft tissue. Soft tissue cutting knives are mainly used to cut soft tissues such as skin, muscles, ligaments, and fascia. These tissues are located inside the human body and are essential for maintaining normal physiological functions of the human body. In medical operations, soft tissue cutting knives are widely used in various surgical operations.
