Fusion device for treating femoral head necrosis

Abstract

The invention discloses a fusion device for treating femoral head necrosis. The fusion device comprises a mesh cage frame, a side hole, a screw and a close nut. The mesh cage frame is arranged outside the fusion device, the side hole is formed in the body portion of the mesh cage frame, the screw is arranged inside the side hole, and the close nut is arranged at the tail of the fusion device. The fusion device is made of metal or alloy with certain mechanical strength, the strength and the force of a femoral head treatment implant are improved, the surface of the fusion device can be kept inside a human body for a long time, the necrosis and collapse femoral head is supported, guarantees are provided for postoperative recovery, pains of a patient are relieved, and the improvement of the medical level is facilitated. The fusion device is simple in structure, low in manufacturing cost and excellent in performance, and the problem that in femoral head treatment at present, a femoral head device with the high mechanical strength and a medical implant which is capable of being kept inside the human body for a long time and used for filling and supporting necrosis collapse does not exist is solved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a fusion device for treating femoral head necrosis. Background technique [0002] Avascular necrosis of the femoral head is a common clinical disease. The current treatment methods include drilling for decompression, implantation of bone flap with blood supply, and artificial joint replacement. In order to realize the function, the filling operation with autologous bone flap and free bone (such as fibula) is cumbersome and has many complications. At present, there are very few implant materials dedicated to filling and supporting the femoral head and neck area at home and abroad. It is not suitable for young people to use artificial joints. Patients treated by replacement urgently need an implant that can integrate with autogenous bone and play a supporting role. [0003] In the clinical treatment of avascular necrosis of the femoral head, the removal and refilling o...
