Abstract
A fixed nail plate passing by vertebral pedicle in front of cervical vertebra comprises a nail plate body (2) provided with a bone hole (4) and is characterized in that an inclined screw hole (1) is arranged at each of two ends of the lower part of the nail plate body (2), a straight screw hole (3) is arranged at the right upper corner of the nail plate body (2), and the bone hole (4) is a waist round hole. The fixed nail plate can enhance the fixing strength and holding force of nail fixing, and the fixing position of a bone block can be adjusted, thereby being beneficial to enhancing the success rate of operations.
Description
Technical field
This utility model relates to medical instruments field, specifically, relates to fixedly nail-plate of a kind of anterior cervical vertebrae pedicle.
Background technology
Anterior cervical decompression bone graft fusion extensive use in cervical spondylosis such as treatment neck marrow the place ahead pressurized or cervical vertebra kyphosis deformity at present; But the excision decompression and the bone grafting internal fixation that need carry out a plurality of vertebral bodys during for the pathological changes that relates to multi-segmental are rebuild; Though adopt preceding road titanium plate internal fixation; But mechanical stability still is limited in this type case, obviously reduces owing to the mechanical stability difference causes fusion rate, thereby causes the failure of performing the operation.At this moment the orthopedist tends to adopt the way of escape to fix simultaneously, so just needs to increase posterior approach.The road is not applied to pedicle fixed pegboard systems in preceding road through vertebral body pedicle of vertebral arch internal fixation raising mechanical stability but still have at present to have the scholar to attempt in the past thus.
Bibliographical information through the anterior cervical vertebrae fixation of pedicle is to adopt the fixing used cervical lateral mass titanium plate bolt system of posterior cervical at present, and this fixed system is straight plate, and screw hole is on same straight line, on same vertebral body, can only fix by single piece of screw.
Though at present the routine pegboard systems that is applied to the anterior cervical vertebrae internal fixation can accomplish that same vertebral body diplopore fixes, two pieces all is to fix through vertebral body, and regular length obviously will be lacked (screw length of use is 1.3 centimetres or 1.5 centimetres at present).
Summary of the invention
The purpose of this utility model provides and a kind ofly can improve screw strength of fixation and hold, and the fixing nail-plate of the anterior cervical vertebrae pedicle of bone grafting position-adjustable.
The technical scheme that realizes above-mentioned purpose is: a kind of anterior cervical vertebrae pedicle is nail-plate fixedly; Comprise the nail-plate body, have the bone grafting hole on the nail-plate body, respectively there is an oblique screw hole at the two ends, bottom of nail-plate body; The upper right corner of nail-plate body has a straight screw hole, and described bone grafting hole is the oval hole.
After adopting technique scheme, screw is squeezed into pedicle of vertebral arch through the inclined hole on the nail-plate body, adopts inclined hole can increase the length that screw is squeezed into, and regular length can reach 3 ~ 4 centimetres, not only can improve the screw strength of fixation, and can improve hold.Because the bone grafting hole on the nail-plate body is the oval hole, therefore when bone grafting, can adjusts the plant bone mass fixed position very easily, thereby improve the success rate of operation.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is done further detailed explanation.
Shown in Fig. 1 ~ 6, a kind of anterior cervical vertebrae pedicle is nail-plate fixedly, comprises nail-plate body 2; Has bone grafting hole 4 on the nail-plate body 2; Respectively there is an oblique screw hole 1 at the two ends, bottom of nail-plate body 2, and the upper right corner of nail-plate body 2 has a straight screw hole 3, and described bone grafting hole 4 is the oval hole.
The operation principle of this utility model is following:
One piece of screw is squeezed into vertebral body through the straight hole on the nail-plate body 23 and is fixed.Other screw is squeezed into pedicle of vertebral arch through the inclined hole on the nail-plate body 21, adopts inclined hole 2 can increase the length that screw is squeezed into, and not only can improve the screw strength of fixation, and can improve hold.
