Summary of the invention
The present invention will solve problems of the prior art exactly, provide a kind of help artificial intervertebral disk with suffer from intervertebral closely contact and fix, artificial intervertebral disk replacement operator in operation under the less destruction cervical vertebra prerequisite is inserted conveniently, effectively shorten operating time, implant the memorial alloy cervical vertebra artificial intervertebral disk that the back increases the stability of artificial intervertebral disk body.
Technical problem of the present invention adopts following technical proposals to solve:
A kind of memorial alloy cervical vertebra artificial intervertebral disk, form by an artificial intervertebral disk body with a gripper shoe of its suit, described artificial intervertebral disk body has tapering, be distributed with the anticreep agnail on the upper and lower surface of artificial intervertebral disk body, the dual-side of upper and lower surface is provided with fixing branch, and the inboard two ends of each fixing branch are respectively equipped with the anticreep pawl.Described gripper shoe cooperates socket with described artificial intervertebral disk body.
Described gripper shoe is horizontal U-shaped structure, and outer end, U-shaped mouth top and bottom is provided with mousing-hook.
The shape side-looking of described artificial intervertebral disk body is " W " type.
The present invention adopts the structure of being made by sheet material that certain taper is arranged, utilize the memory characteristic of memory alloy material, persistent pressure function after the recovery of shape, help artificial intervertebral disk with suffer from intervertebral closely contact and fix the strong fixing stability that can increase the trouble vertebra of formation; Adopt the fixing branch of band pawl simple in structure, fixing branch is inserted conveniently, effectively shortens operating time.Implant the stability that the back increases the artificial intervertebral disk body; Its main body two sides are respectively equipped with three anticreep agnails, can prevent deviating from of main body after the recovery of shape, have strengthened the stability of intervertebral disc more; The gripper shoe of the U-shaped structure of being made by sheet material after the recovery of shape, has the effect of persistent pressure, support to the intervertebral disk body, and its four mousing-hooks are simultaneously inserted in the hole of intervertebral disk bodies, and both are become one, and finish fixing jointly.The present invention can active memory alloy artificial intervertebral disc by implant one at intervertebral space, has not only shortened operating time, has simplified operation technique, and has not needed to get bone, bone grafting, has reduced the many miseries of patient;-decide to keep on the degree or increased the mobility of pathological changes vertebra joint, reduced due to illness become vertebra joint converged fixed after, the phenomenon that adjacent vertebra joint load increases, slow down the regression that adjacent vertebra joint produces therefrom, realized keeping motor function, delay and reducing the purpose that the Secondary cases regression appears in adjacent segment.
With the artificial intervertebral disc of the basis of board making, art shapes is simple, and easily deformable inserting installed stable after the complex.Easy to use in operation, fixation, reliable.After this artificial intervertebral disk is installed, keep cervical vertebrate active degree, reduced contiguous vertebral body complication.Present technique has excellent application value and application prospect, and rational Application can obtain satisfactory effect, compares the quality of life that more helps to improve the patient to a certain extent with cervical fusion surgery, has good economic and social benefit.
