Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • Figure 1 is a schematic view of the structure of the present invention.
  • FIG. 2 is a schematic view showing the structure of a joint capsule attachment ring of the present invention.

Abstract

La présente invention concerne un appareil destiné à prévenir la dislocation d'une tête fémorale prothétique et son procédé d'utilisation. Le col (5) fémoral raccordé à une prothèse (4) est inséré dans la tête (2) fémorale prothétique, un anneau (3) de fixation de capsule articulaire est emmanché sur le col (5) fémoral raccordé à la prothèse (4), et une fixation (1) de contour de suture de capsule articulaire est raccordée à l'anneau (3) de fixation de capsule articulaire. Selon le procédé d'utilisation de l'appareil destiné à prévenir la dislocation d'une tête fémorale prothétique, pendant la chirurgie, une fois que la capsule articulaire est incisée dans la longueur et ouverte, l'appareil est placé à l'intérieur, puis la capsule articulaire ouverte est refermée avant de passer à travers la fixation (1) de contour de suture de capsule articulaire en vue d'une suture et d'une stabilisation. Cet appareil peut être utilisé dans la chirurgie de remplacement de la tête fémorale prothétique ou de la capsule articulaire. Ledit appareil permet de résoudre le problème selon lequel, lorsqu'une tête fémorale prothétique et un col fémoral prothétique sont dépourvus de la protection enveloppante d'une capsule articulaire, la tête fémorale prothétique est susceptible de subir une dislocation à partir de l'acétabulum, ce qui donne lieu à un échec chirurgical.
