Abstract
An artificial human cervical intervertebral disk is composed of two bases and a spherical joint consisting of concave and convex parts, which are matched and fixed to based via dovetail groove structure. Said artificial disk is made of Ti alloy, medical stainless steel or medical polyethylene material, and can be transplanted into human cervical vertebra.
Description
The invention belongs to technical field of medical instruments, be specifically related to a kind of artificial human cervical intervertebral disk.
Human cervical spine is volume minimum but motility maximum in the spinal column, the highest sections of movable frequency.Owing to constantly bear various loads, strain, and the prolongation of the average life span, because of the sickness rate of cervical vertebra instability, prolapse of cervical intervertebral disc and cervical spondylosis due to the degeneration becomes the modal disease of Orthopaedics Clinic, and due to illness a lot of patients may become the infringement spinal nervous tissue and cause limbs disturbance, even cause quadriplegia, cause huge misery for patient, relatives.At present, treat above-mentioned disease clinically and adopt the cervical vertebral space decompression and fusion more, be i.e. bone grafting internal fixation with steel plate or interface implants bone graft fusion.Above-mentioned therapy has been destroyed the physiological activity function (particularly multi-segmental cervical spondylosis) of cervical intervertebral disk in treatment, make to merge to go up the power increase that sections and following sections bear and the degeneration of bringing out upper and lower intervertebral space.
The objective of the invention is to design a kind of can the decompression, and can recover the cervical intervertebral disk prosthesis of this gap physiological activity function and gap physiology height cervical vertebral space.
The cervical intervertebral disk prosthesis of the present invention's design is made of two pedestals and a sphere joint.Wherein, two pedestal sizes are mated with the cervical intervertebral disk size, and thickness satisfies requirement of strength and gets final product, and is generally 2-4mm, and its back side is respectively equipped with caltrop, and the front has a dovetail groove; The sphere joint is divided into convex body and two parts of concaver, the protruding sphere of convex body and the concave spherical surface of concaver mate mutually, the spherical radius that is convex surface and concave surface is consistent, and the base diameter of protruding sphere (is the base diameter of spherical crown, down with) be slightly larger than the base diameter of concave spherical surface, the back side of convex body and concaver is respectively equipped with the swallow-tail form tongue, and this tongue just in time is embedded in respectively in the dovetail groove in two pedestal fronts.As Fig. 1-shown in Figure 9.
The cervical intervertebral disk prosthesis of the present invention design can adopt medical titanium alloy or medical stainless steel, or material such as medical polyethylene.Usually, the convex body in sphere joint adopts medical titanium alloy, and concaver adopts medical polyethylene comparatively suitable.
According to the physiological activity characteristic of people's neck bone, it bends and stretches before and after can doing, left and right sides lateral bending, actions such as one-sided rotation.And, different neck bone sections, it bends and stretches, the angle of lateral bending, rotation all has difference.The reference data that following table generally, is arranged:
| Cervical vertebra sections C 3-4C 4-6C 5-6C 6-7 | Bend and stretch 15 20 20 7 | Lateral bending (one-sided) 11 11 87 | Rotation (one-sided) 7776 |
Illustrate: C represents neck bone, and subscript is represented sections.Bend and stretch, the unit of lateral bending, rotation is degree.
According to the lesion locations and the range of activity thereof of cervical intervertebral disk, the plurality of specifications size that cervical intervertebral disk prosthesis can be designed to vary in size is with the requirement of the bending and stretching of the cervical vertebra that satisfies different parts, lateral bending and rotation.
The cervical intervertebral disk prosthesis of the present invention's design can be by surgical operation with its position of implanting patient's cervical spine disk pathological change, and the convex body and the concaver in sphere joint are involutory, and two pedestals are fixed two parts about the sphere joint.Two pedestals are fixed in up and down on two cervical vertebral body sections by caltrop.Use this cervical intervertebral disk prosthesis, can reduce pressure, and can recover the physiological activity function and the physiology height in this gap cervical vertebral space.This prosthese is applicable to the cervical vertebra instability due to degeneration, prolapse of cervical intervertebral disc and cervical spondylosis etc.
In order making between cervical intervertebral disk prosthesis and the upper and lower cervical vertebral body sections better secure fit to be arranged, can a fixing head to be set respectively, have fixing hole on this plate two pedestal sides.Available screw hammers into the sections up and down of cervical vertebral body by this fixing hole, thereby pedestal is more stably fixed.
The moving of transfiniting of two parts or break away from up and down for fear of the sphere joint of the cervical intervertebral disk prosthesis that may occur can be set up the connection tie between last bottom base, two parts connection up and down, but the activity between two parts about not influencing.
According to the requirement of cervical intervertebral disk joint motion, the movable corner of two spheres up and down of this prosthese (angle of the angle α-two spherical crown bottom surface among Fig. 8) can be in 0-8 degree range.
Further describe the present invention below in conjunction with drawings and Examples.
Fig. 1 is the substrate vertical view.
Fig. 2 is the substrate front view.
Fig. 3 is the substrate left view.
Fig. 4 is the front view of sphere joint convex body.
Fig. 5 is the side view of sphere joint convex body.
Fig. 6 is the front view of sphere joint concaver.
Fig. 7 is the side view of sphere joint concaver.
Fig. 8 is sphere joint two parts cooperation diagram up and down.
Fig. 9 is this cervical intervertebral disk prosthesis overall structure diagram.
Number in the figure: 1 is pedestal, and 2 is the sphere joint, and 3 are the ecthoaeum nail, 4 is sphere joint convex body, and 5 is sphere joint concaver, and 6 is the dovetail groove in pedestal front, 7 is the swallow-tail form tongue at the back side, sphere joint, and 8 is the lateral fixing head of pedestal, and 9 is the fixing hole on the fixing head.
Embodiment: with reference to the accompanying drawings, the plane of pedestal 1 is a square, the length of side is 12mm, and thickness is 2.5mm, and the caltrop at pedestal 1 back side has 4, caltrop length is 3.5mm, lateral fixing head 8 is half garden shape, and width is 7.5mm, and the diameter of the fixing hole 9 on the plate is 3.5mm, the width suitable for reading of front dovetail groove 6 is 6mm, and the wide rate of end opening is 7.75mm.The convex body 4 in sphere joint 2 and the base plane of concaver 5 are square, and the length of side is 11mm, and the thickness of bottom is 2.5mm, and the size of back side swallow-tail form tongue 7 is corresponding identical with the size of pedestal 1 front dovetail groove, make both can be chimeric closely.The protruding sphere base diameter of convex body 4 is 9.47mm, and the spherical crown height is 2.28mm, and the concave spherical surface base diameter of concaver 5 is 8.17mm, and the spherical crown height is 1.78mm.The convex body 4 in pedestal 1 and sphere joint 2 adopts the medical titanium alloy material, and concaver 5 adopts the medical polyethylene material.The cervical intervertebral disk prosthesis of above-mentioned specification is applicable to the patient that the middle age cervical intervertebral disk is bigger.
