As an important auxiliary equipment in medical operation, traction frame aims to provide stable support and accurate positioning for patients. Specific to the different types of traction frames, they each assume a key role. The surgical head frame plays a central role in neurosurgery and other head procedures. The surgical head frame is used to firmly and accurately fix the patient's head, ensuring the stability of the head position during the operation. The orthopaedic traction frame is mainly used in fracture treatment and orthopaedic surgery to support and fix the bone or joint, help maintain the correct alignment, promote the normal healing of the bone, and reduce postoperative complications. Especially during lower limb surgery or lithotripsy. The stapedium-type leg brace can accurately fix and support the leg, mimic the shape of the stirrup, stabilize the leg and facilitate the operation of the surgical area, ensure accurate surgical positioning, and reduce patient discomfort.
