Abstract
The utility model provides a spinal anterior intervertebral disc device used for solving the problem that vertebral body collapse is easy to occur due to the long-time use. The spinal anterior intervertebral disc device comprises two vertebral plates used for being matched with a vertebral body end face of a human man spine, wherein the two vertebral plates are relatively mounted on a supporting mechanism, the supporting mechanism comprises two supporting rods and two connecting plates detachably mounted on the supporting rods, spherical heads are arranged on the connecting plates, and the vertebral plates are provided with long-shaped grooves matched with the spherical heads. The spinal anterior intervertebral disc device is simple in structure, can accept a transfer operation for treatment of vertebral segments, avoids the generation of the vertebral body collapse, accords with arbitrary shape changes of the vertebra, and is matched with an artificial vertebral body and capable of achieving biological vertebral body replacement.
Description
Technical field
This utility model relates to technical field of medical instruments, refers to especially the front road of a kind of spinal column intervertebral disc device.
Background technology
Intervertebral disc is between human spine two vertebral bodys, a seal that is formed by cartilaginous lamina, fibrous ring, vertebral pulp, there is up and down cartilaginous lamina to be covered on the vertebral body, cartilaginous lamina up and down seals vertebral pulp with fibrous ring, fibrous ring is made of the fibrous cartilage of collagenous fiber bundle, be positioned at vertebral pulp around, the mutual diagonal juxtaposition of the fibre bundle of fibrous ring, make fibrous ring become solid tissue, can bear larger bending and torsion load.
The intervertebral disc of Whole Body has 23, the intervertebral disc thickness of waist is the thickest, the gross thickness of intervertebral disc can reach the 1/4-1/5 of full spinal column overall length, the actual prolapse of lumbar intervertebral disc that refers to of the intervertebral disk hernia that it has often been said, in fact also exist intervertebral disc between cervical vertebra, the thoracic vertebra, just symptom is different with Therapeutic Method.At present; the biological intervertebral disc of human body need to be changed by more serious damage afterwards usually; by the cooperate function of recovering spinal column of artificial intervertebral disc with vertebral body; but artificial intervertebral disc of the prior art is simple in structure, and shape is more single, and mobility is less; can not realize the variation of vertebra arbitrary shape; and its robustness is not high, is easy to occur the problem of subsiding of vertebral body after long-time the use, affects patient's normal recovery.
The utility model content
The utility model proposes the front road of a kind of spinal column intervertebral disc device, it is simple in structure, and is easy to use, can realize the random shape variations of vertebral body, and the problem of collapse of vertebra also can not occur after long-time the use.
The technical solution of the utility model is achieved in that the front road of spinal column intervertebral disc device, comprise for suitable two vertebral plates of human spine's vertebral body end face, described two vertebral plates are installed on the supporting mechanism relatively.
As preferred embodiment a kind of, described supporting mechanism comprises support stick, and described support stick is provided with dismountable two connecting plates, and described two vertebral plates are articulated in respectively on the corresponding connecting plate.
As preferred embodiment a kind of, described support stick is two, has the connecting hole corresponding with described support stick on described two connecting plates, and described connecting plate is fixed on the described support stick by the pressure nail that is arranged in the described connecting hole.
As preferred embodiment a kind of, described connecting plate is provided with ballhead, has the elongate slots suitable with described ballhead on the described vertebral plate.
After having adopted technique scheme, the beneficial effects of the utility model are: owing at supporting mechanism two relative vertebral plates have been installed, and these two vertebral plates can be suitable with human spine's vertebral body end face, then by two vertebral plates with the vertebral body pinching in the centre vertebral body of fixing human well, thereby recover the function of spinal column.
Because this supporting mechanism comprises support stick and detachably is fixed on two connecting plates on the support stick, all be hinged with vertebral plate on each connecting plate, then not only easy installation and removal of this device, can accept the transfer operative treatment of vertebra section, and the mobility of vertebral plate is large, can realize the variation of vertebra arbitrary shape.
Because connecting plate is suitable by the elongate slots of offering on ballhead and the vertebral plate, then realize the movement of the left and right directions of vertebral plate by the rotational of ballhead in elongate slots, and the movement of in elongate slots, moving the fore-and-aft direction that can realize vertebral plate by ballhead along its bearing of trend.
In addition, the shape of vertebral plate can be changed according to the vertebral body shape of human body different parts, and when the waist intervertebral disc of human body need to be changed, the shape of vertebral plate should be suitable with the vertebral body shape of human body waist; When the intervertebral disc at the cervical vertebra of human body or thoracic vertebra position need to be changed, the shape of vertebral plate should be suitable with the vertebral body shape at human cervical spine or lumbar vertebra position, thereby make this device can satisfy the demand that human body different parts intervertebral disc is changed.
