Abstract

The invention discloses a positioning hip joint and ankle joint center positioner which comprises an ankle fixing mechanism, two telescopic rods, a positioning arc rod, a sliding positioner, a hip joint positioning mechanism and a force line rod. Telescopic rods are arranged on the two sides of the ankle fixing mechanism; the two ends of the positioning arc rod are connected with the far ends of the telescopic rods respectively. The positioning arc rod comprises a sliding groove formed in the inner arc face and metal positioning scales arranged on the outer arc face. The sliding positioner comprises a first sliding block and a second sliding block which are slidably connected to the positioning arc rod in a sleeving mode. A positioning ring is arranged between the ends, close to the inner arc face of the positioning arc rod, of the first sliding block and the second sliding block. The hip joint positioning mechanism is arranged at the groin of the patient; one end of the force line rod is connected with the positioning ring, and the other end is connected with the hip joint positioning mechanism. In conclusion, the device has the advantages of novel structure, convenience in use, small error and the like.

Description

technical field [0001] The invention belongs to the technical field of joint positioning equipment, in particular to a center positioner for positioning hip joints and ankle joints. Background technique [0002] Knee arthritis is the most common joint disease in the elderly, and its incidence increases with age. It usually causes symptoms such as repeated knee joint swelling and pain, and limited mobility. Over the years, it will lead to joint deformation, resulting in "O-shaped legs" or "X-shaped legs" and other deformities. High tibial osteotomy, referred to as HTO, refers to high tibial osteotomy, which corrects uneven force lines, improves symptoms, relieves pain, and can preserve bone to the maximum extent and reduce bone destruction, thereby delaying the progression of knee osteoarthritis. However, in the HTO operation, in order to conveniently determine the center of the hip joint and ankle joint, it is necessary to perform multiple perspectives during the operation,...
