Abstract

An apparatus for preventing prosthetic femur head dislocation and a method for using same, wherein the femur neck (5) connected to a prosthesis (4) is inserted into the prosthetic femur head (2), an articular capsule attachment ring (3) is sleevingly arranged on the femur neck (5) connected to the prosthesis (4), and an articular capsule suture skirt attachment (1) is connected to the articular capsule attachment ring (3). In the method for using the apparatus for preventing prosthetic femur head dislocation, during surgery, once the articular capsule is incised lengthwise and flipped open, the apparatus is placed therein and then the opened articular capsule is flipped closed and passed through the articular capsule suture skirt attachment (1) for suturing and stabilizing. The apparatus can be used in replacement surgery of the prosthetic femur head or of the articular capsule. This apparatus solves the problem wherein when a prosthetic femur head and a prosthetic femur neck are without the embracing protection of an articular capsule, the prosthetic femur head is prone to dislocation from the acetabulum, causing surgery to fail.

Description

一种防止人工股骨头脱位的装置及其使用方法  Device for preventing dislocation of artificial femoral head and using method thereof
技术领域:Technical field:
本发明属于医疗领域的手术假体，特别是一种防止人工股骨头脱位的装置及其使用方法。The invention belongs to a surgical prosthesis in the medical field, in particular to a device for preventing dislocation of an artificial femoral head and a method of using the same.
背景技术:Background technique:
人工股骨头或髋关节置换手术需要将假体股骨颈插接于假体股骨头内，再将假体股骨头置于假体髋臼内，手术时将关节囊切除。这样，假体股骨头与假体股骨颈因为失去了关节囊的兜托保护，容易发生假体股骨头从髋臼中脱位，导致手术失败。Artificial femoral head or hip replacement surgery requires the insertion of the prosthetic femoral neck into the prosthetic femoral head, and the prosthetic femoral head is placed in the prosthetic acetabulum, and the joint capsule is removed during surgery. In this way, the prosthetic femoral head and the prosthetic femoral neck are prone to dislocation of the prosthetic femoral head from the acetabulum due to the loss of the protection of the joint capsule, resulting in surgical failure.
发明内容:Summary of the invention:
本发明的目的就是提出一种防止人工股骨头脱位的装置及其使用方法的技术方案，以解决背景技术存在的：假体股骨头与假体股骨颈因为失去了关节囊的兜托保护，容易发生假体股骨头从髋臼中脱位，导致于术失败。解决该技术问题所采用的技术方案是：一种防止人工股骨头脱位的装置， 假体连接的股骨颈插接于假体股骨头内，假体连接的股骨颈上环套关节囊附着环，关节囊附着环上连接关节囊缝合附着裙边。其中，关节囊缝合附着裙边为与关节囊附着环同轴心的扇形。关节囊缝合附着裙边中间设置若干加强杆。一种防止人工股骨头脱位的装置的使用方法，手术中将关节囊纵向切开并翻开，将上述装置置入其中后，将翻开的关节囊翻回后穿过关节囊缝合附着裙边进行缝合固定。The object of the present invention is to provide a device for preventing dislocation of an artificial femoral head and a technical solution thereof for solving the background art: the prosthetic femoral head and the prosthetic femoral neck are easily protected due to the loss of the joint capsule. Dislocation of the prosthetic femoral head from the acetabulum resulted in failure of the procedure. The technical solution adopted to solve the technical problem is: a device for preventing dislocation of the artificial femoral head, The femoral neck connected by the prosthesis is inserted into the femoral head of the prosthesis, and the joint of the femoral neck of the prosthesis is attached to the ring of the joint capsule, and the joint capsule is attached to the joint capsule to suspend the skirt. Wherein, the joint capsule suture attachment skirt is a fan shape concentric with the joint capsule attachment ring. A plurality of reinforcing rods are arranged in the middle of the joint capsule suture attachment skirt. A method for preventing the dislocation of the artificial femoral head, wherein the joint capsule is longitudinally cut and opened during the operation, and after the device is placed therein, the opened joint capsule is turned back and then the joint capsule is sutured and attached to the skirt. Stitching is fixed.
本发明与现有技术比较所具有的有益效果是：由于采用上述技术方案，手术中将关节囊纵向切开并翻开，将本发明置入其中后，将翻开的关节囊翻下后穿过关节囊缝合附着裙边进行缝合固定。这样，关节囊对假体股骨头与假体股骨颈起到了兜托保护作用，有效防止发生假体股骨头从髋臼中脱位，并且不影响假体关节的功能。Compared with the prior art, the present invention has the beneficial effects that: due to the above technical solution, the joint capsule is longitudinally cut and opened during surgery, and after the invention is placed therein, the opened joint capsule is turned down and worn. The joint capsule is sutured and attached to the skirt for suture fixation. In this way, the joint capsule plays a protective role on the femoral head of the prosthesis and the femoral neck of the prosthesis, effectively preventing the dislocation of the prosthetic femoral head from the acetabulum and not affecting the function of the prosthetic joint.
