A Kocher Retractor is a surgical tool used to hold back tissues, providing a clear view and access to the surgical site. It is a handheld, manual, and non-self-retaining instrument. This type of retractor typically has a handle and a curved blade with multiple prongs, which can be sharp or blunt. It is commonly used in various procedures, including orthopedic and general surgeries, to gently separate tissues and maintain a clear operating field. The prongs are designed to rake or pull tissue away from the area that needs to be viewed during an operation.
