Description

Fusiform is in same direction as fixed type of thorn hook vertebra joint and is fused ware

Technical Field

The utility model relates to the field of medical tools, concretely relates to fusiform is in same direction as fixed type of thorn hook vertebra joint and is fused ware.

Background

Robinson and Smith proposed intervertebral bone grafting fusion in the anterior cervical disc removal in 1958, using autologous bone grafting to promote fusion rates. The operation type can directly cut off the pressure-inducing object to relieve the spinal cord compression, so that the symptoms of a patient are greatly improved, but the simple anterior decompression bone grafting fusion operation without steel plate screw fixation easily causes cervical instability, leads to the serious problems of non-fusion of bone grafting blocks, falling-out of bone grafting blocks and the like. Therefore, Bohler and Gaudemak firstly propose to use steel plate screws for fixation in anterior cervical spine surgery in 1964, so that the fusion rate is improved, the cervical spine sequence is stabilized, and the spinal deformity is corrected, but autologous bones can collapse and be absorbed to cause fusion failure in the later period of intervertebral implantation, and secondary spinal deformity occurs, so that the internal objects for intervertebral fusion continuously appear, for example, Cage and various fusion devices made of Pick village materials are applied to the anterior cervical spine surgery, the fusion rate is improved, the problems of collapse and the like are solved, the anterior cervical disc resection fusion fixation (ACDF) becomes the golden standard for treating cervical spondylosis, the classical anterior intervertebral bone grafting or anterior steel plate internal fixation has obtained good clinical curative effect, but the postoperative swallowing discomfort and other complications are caused by the loosening of the screws, the fracture of the steel plate, the displacement of the steel plate and the stimulation of the esophagus of the steel plate occur. In recent years, spine minimally invasive surgery is fast, and anterior cervical minimally invasive surgery makes it difficult and serious to establish a channel by puncture expansion due to complexity of an anatomical structure and importance of tissue and organs.

The traditional anterior cervical median embedding fusion cage cannot be used for operation in a channel, and a fusiform forward-barbed vertebral joint fixing fusion cage is designed for micro-channel application.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fusiform is in same direction as fixed type of thorn hook vertebra joint and is fused ware, uses in flexible eccentric expansible anterior cervical way microchannel system, has solved anterior cervical way minimal access surgery cervical vertebra and has stabilized and later stage centrum fusion problem immediately.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a fusiformis is in same direction as fixed type of thorn hook vertebra joint fuses ware, includes and fuses the ware body and set up the elliptical aperture at fusion ware body upper and lower both sides face, left and right sides face, fuse the ware and include integrated into one piece's fusiformis front portion and cuboid rear portion, the anterior length of fusiformis is 3mm, is formed by cuboid rear portion gradual change, is provided with in the same direction as the shape barb on it, and cuboid rear portion vertical part is provided with in the same direction as the shape barb.

Furthermore, there are three types at the cuboid rear portion, and the length is 16mm, 18mm, 20mm respectively, and the width is 6mm, 7mm, 8mm respectively, and the height is 12 mm.

Further, the diameter of the elliptical hole is 6mm, and the elliptical hole is used for bone grafting.

The utility model discloses following beneficial effect has:

the utility model is applied in a flexible eccentric expandable anterior cervical micro-channel system, which solves the problems of immediate cervical stabilization and later centrum fusion in anterior cervical minimally invasive surgery; specifically, the method comprises the following steps: the fusion cage of the utility model can be placed in a micro channel with the diameter of 16mm, and the smooth thorn on the fusion cage can firmly embed the fusion cage into the uncinate vertebral joint to achieve the effect of immediate stabilization; the fusion device is implanted with autogenous bone or allogeneic bone to achieve later-stage stability.
