Description

technical field [0001] The invention relates to the technical field of orthopedics, in particular to a surgical retractor for orthopedic tumors. Background technique [0002] Orthopedics is one of the common departments in the hospital. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system. It uses medicine and surgery to maintain the normal shape and function of the system. In orthopedic surgery, surgical retractors are often used. Its role It is to pull the external tissue of the bone apart and fix it, which is convenient for subsequent operations. [0003] Most of the existing surgical retractors are manually pulled, it is difficult to maintain the stability of the device, and it is difficult to illuminate during the operation; the retractors need to be cleaned after use, and the existing retractors are not stored after cleaning. position, resulting in the mixing of retractors and other devices, resulting in secondary pollution.
