Abstract
The utility model provides a cervical vertebra of meeting auto -eject fuses ware, including integration ware main part, the upper and lower surface of fusing the ware main part is equipped with a plurality of pinholes, installs the round pin that develops in every pinhole, the lower extreme of development round pin supports there is the spring, the pinhole is the type type, and the last stomidium of type has the several sulculus, the round pin lower extreme that develops is equipped with and passes swelling of sulculus, protruding can the counterbalance with the horizontal plane of the last stomidium of type is fixed. The utility model discloses developing and selling under the spring force of spring acts on, promotion development round pin, messenger's integration ware and upper and lower vertebral plate be in close contact with more, fuses the contact force increase of ware and upper and lower vertebral plate, and the integration ware is fixed more firmly in the centrum, improves the integration rate.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specially a kind of cervical vertebral fusion cage of meeting automatic spring.
Background technology
Intervertebral disk hernia compressing spinal cord or nerve can cause pain, even quadriplegia, and adopting discectomy and imposing fusion device is common therapeutic modality.Common fusion device upper and lower surface all has dentation to increase the contact force of fusion device and upper and lower vertebral plate, but because gap between everyone upper and lower vertebral plate, angle are different, there will be fusion device contacts not good with upper and lower vertebral plate, the contact force of fusion device and upper and lower vertebral plate is not enough, cause fusion device to be fixed insecure, merge actual effect phenomenon.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cervical vertebral fusion cage of meeting automatic spring, and development pin, under the spring-force driven dual of spring, promotes development and sells, enable fusion device and upper and lower vertebral plate more close contact, improve fusion rate.
This utility model solves the problems of the technologies described above adopted technical scheme:
A cervical vertebral fusion cage for meeting automatic spring, include fusion device main body, the upper and lower surface of described fusion device main body is provided with some pin-and-holes, being provided with development pin in each pin-and-hole, and the lower end of described development pin has spring;
Described pin-and-hole is the upper end hole of convex, convex, has several sulculus;
Described development pin lower end is provided with can through the projection of described sulculus, and described projection can offset fixing with the horizontal plane of the upper end hole of convex.
Straight-through bone grafting hole is had in the middle of described fusion device main body.
There is dentation on the upper and lower surface of fusion device.
It is wedge angle or inverted triangle shape that the head contacted with vertebral plate is sold in described development.
Compared with prior art, this utility model has following beneficial effect: development pin is under the spring-force driven dual of spring, promote development pin, enable fusion device and upper and lower vertebral plate more close contact, the contact force of fusion device and upper and lower vertebral plate increases, fusion device is fixing more firm in vertebral body, improves fusion rate.
