Spinal Percutaneous Pedicle Vertebral Restoration Bone Graft

Abstract

Spine percutaneous vertebral pedicle centrum reduction bone grafting apparatus comprises a bone grafting pipeline assembly, a core rod assembly, a bone grafting pipeline fixing part 7, a depth-limiting adjusting part 8 and a push rod 9, wherein the bone grafting pipeline assembly comprises a hopper 1, a bone grafting pipe 2 and a plug 3, the upper end of the bone grafting pipe 2 is connected to the lower end of the hopper 1 through the bone grafting pipeline fixing part 7, a hole 21 is formed in the pipe wall of the lower end of the bone grafting pipe 2, the plug 3 is installed in the bone grafting pipe 2 and located below the hole 21, the upper end face and the lower end face of the plug 3 are both slopes, and the lower end of the bone grafting pipe 2 is in the shape of a sharp corner. Compared with the prior art, the spine percutaneous vertebral pedicle centrum reduction bone grafting apparatus has the advantages that the overall structure is simple, stable and reliable, manufacturing cost is low, skin and tissue incision and exposure of a bone grafting entry point (entering the centrum through the vertebral pedicle) of a thoracic waist fracture zygopophysis occurring in a traditional open operation are avoided, tissue trauma and the amount of bleeding during the operation are reduced, and the problems existing in the traditional open operation that recovering time is long and the number of postoperative complications is large are solved.

Description

technical field

[0001] The invention relates to an orthopedic medical instrument, in particular to a bone grafting device for percutaneous vertebral pedicle restoration of the spine. Background technique

[0002] Human spine thoracolumbar fractures are mostly treated with traditional open surgery. During the treatment process, it is necessary to open the skin and implant autologous or allogeneic bone into the injured thoracolumbar fracture through the pedicle. The purpose of treatment can only be achieved through steps such as incision of the skin, removal of tissues, and exposure of the articular process of the vertebral body of the thoracolumbar fracture. There are disadvantages such as large tissue trauma, heavy bleeding, long recovery time, and many postoperative complications. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a spinal percutaneous pedicle vertebral reconstruction bone...
