Technical Field
The invention relates to the technical field of medical instruments, in particular to a reduction fixing clamp for traumatic orthopedics with accurate positioning.
Background
Orthopedics is one of the most common departments in all hospitals, and mainly studies the anatomy, physiology and pathology of the skeletal muscle system, and maintains and develops the normal form and function of the system by using medicines, operations and physical methods. With the change of times and society, the orthopedic injury spectrum has obvious changes, for example, diseases such as osteoarticular tuberculosis, osteomyelitis, poliomyelitis and the like are obviously reduced, and the injuries caused by traffic accidents are obviously increased. Common orthopedic diseases are: patellar fracture, ulnar nerve injury, congenital hip varus, severed finger replantation, inter-digital neuralgia, fracture of external tubercle after talus, thumb reconstruction, congenital tibial defect, catarrh, infectious costal chondritis, temporomandibular joint stiffness, rheumatic fever, fracture of orbital fracture, popliteal tendonitis, metatarsophalangeal arthralgia, posterior tibial neuralgia, anterior tendonitis of achilles, fibromyalgia, bursitis, infectious arthritis, scaphoid osteochondrosis of foot, postural pain in waist and lower extremities, Reiter syndrome, causalgia, fibromyalgia syndrome and the like.
