Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the bone graft cage 100 for cervical vertebra subtotal resection of the present invention is made of carbon fiber composite material and has a hexahedral structure, wherein the top surface 101, the bottom surface 102, the left surface 103, the right surface 104, and the front surface 105 are all provided with windows 200, The back is closed.

[0014] In addition, the top surface 101 and the bottom surface 102 are inclined surfaces anatomically consistent with the inclination of the end surface of the cervical vertebral body.

[0015] Adopt such structure, the bone grafting cage 100 that crushed bone is housed is placed in the rectangular cavity of vertebral body, the top surface 101 of bone grafting cage 100, the bottom surface 102, the left side 103, the right side 104 all can be well with the rectangular cavity. The cavity wall is anastomosed, so that the contact area between the broken bone and the bone of the rectangular ca...

Abstract

The invention discloses a bone laying cage used after subtotal cervical vertebrectomy. The bone laying cage has a hexahedral structure of a carbon fiber composite material; the top, the bottom, the left, the right and the front of the bone laying cage are provided with windows; and the back of the bone laying cage is closed. The bone laying cage has the advantage of allowing the crushed cervical vertebra to fully grow in the cavity of the vertebral body, and is favorable for quick recovery of a patient.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a bone grafting cage used after subtotal cervical vertebra resection. Background technique [0002] To treat cervical spondylosis, it is sometimes necessary to perform subtotal cervical spondylectomy, that is, to cut a rectangular cavity on the vertebral body of the cervical spine. The bone grows in the rectangular space and grows with the bone on the walls of the rectangular cavity. In the prior art, the crushed bone is placed in a cylindrical bone graft cage, and then the bone graft cage is placed in the cavity, allowing the crushed bone to pass through the upper hole of the bone graft cage and the bone on the rectangular cavity wall. grow together. Since the bone grafting cage is cylindrical, the contact area between the crushed bone and the rectangular cavity wall is relatively small, which is not conducive to the sufficient growth of the crushed bone to be connecte...
