Abstract
The utility model relates to an one -way intervertebral fusion fixing device of cervical vertebra. One -way intervertebral fusion fixing device of cervical vertebra include the fix with screw portion of front end and the intervertebral fusion portion of rear end, the left and right both sides of fix with screw portion set up the screw of symmetric distribution respectively, the screw is that the consequently screw of slope can pass through the screw will intervertebral fusion portion is fixed in on the soleplate of the little articular lower section centrum of dislocation, be provided with locking device between the screw, be used for inserting the screw of screw pins in order to avoid the screw is deviate from, consequently intervertebral fusion portion is fit for placing to be resetd between two centrums of back in the little abarticulation of the two sides of cervical vertebra for replace the intervertebral disc of removing in the cervical vertebra operation. The device can reduce the complexity of cervical vertebra operation, reaches the fixed effect of better stability to the reduction is to patient's wound.
Description
Technical field
This utility model relates to a kind of Orthopedic Clinical apparatus, particularly relates to the unidirectional intervertebral fusion fixture of a kind of cervical vertebra.
Background technology
For cervical spine injury, especially the lower articular face completeness dislocation with traumatic is comparatively serious, be common in neck 5/6 and neck 6/7, curative effect after operative treatment then can by the impact of many factors, comprising the dislocation of nerve injury, intervertebral disc, the fracture of soleplate, the dislocation in cervical vertebra joint and serious posterior longitudinal ligament injury, also have selection and the success or not of repositioning method, the experience etc. of operator.Operation method comprises simple anterior approach, simple posterior approach, Qian Lu-posterior approach, the way of escape-anterior approach and the front road-way of escape-anterior approach, and the most frequently used modus operandi is front road-posterior approach, in particular for Bilateral Cervical vertebral articulations dislocation companion intercalated disc break Nucleus pulposus compressing spinal cord patient, for completing effective direct reduction of the way of escape, front road is the unidirectional fixed form of row decompression only, it comprises Interal fixation, unspecific steel plate screw is fixed, and the anterior decompression that even only row is simple such as chunky shape spongy bone is filled.With in road of going forward-posterior approach mode, not all rightly after anterior decompression fixing obviously make patient stand up to do Posterior fixation to there is very large spinal compression risk, itself stability is also inadequate again.And for the unidirectional fixed form of anterior decompression, still there is no the unidirectional intervertebral confluence fixator of cervical vertebra on special premenstrual road at present to carry out stable fixing.Clinical conventional fusion device does not possess fixed function usually, and needs the auxiliary screw that carries out of Neck dissection fixing to prevent Invasive lumbar fusion device from deviating from.In recent years, the anterior approach intervertebral rivet fusion device having scholar to invent himself with two-way bolt fixed function, and to be well used clinically.But this fusion device breaks for the flexing stretching companion intercalated disc of Cervical vertebra and joint strand lock damage but can not use, and is therefore necessary to develop the new unidirectional intervertebral fusion fixture of cervical vertebra.
Summary of the invention
The purpose of this utility model is to provide a kind of novel cervical vertebra unidirectional intervertebral fusion fixture, and this device can reduce the complexity of cervical operation, reaches and better stablizes fixed effect, and reduces the wound to patient.
The unidirectional intervertebral fusion fixture of cervical vertebra described in the utility model comprises the screw fixed part of front end and the intervertebral fusion portion of rear end; The arranged on left and right sides of described screw fixed part arranges symmetrical screw respectively, and described screw is that described intervertebral fusion portion is fixed on the soleplate of the lower joint vertebral body of dislocation Minor articulus by inclination so that screw by described screw; Locking device is provided with between described screw, for the screw inserting described screw is pinned in order to avoid screw is deviate from, so that described intervertebral fusion portion is applicable to being placed on cervical bilateral dislocation and is resetted between rear two vertebral bodys, for the intervertebral disc extractd in alternative cervical operation.
According to the further feature of cervical vertebra of the present invention unidirectional intervertebral fusion fixture, the incline direction of described screw becomes the angle of 30 degree with fusion device.
Cervical vertebra described in the utility model unidirectional intervertebral fusion fixture is the custom-designed intervertebral fusion fixture being applicable to cervical bilateral dislocation through anterior approach, the broken shape spongy bone filling mode more in the past used, or use unspecific steel plate screw fixed form, this device can reset to cervical vertebra better and keep its stability, is more conducive to simplifying operation process.

Detailed description of the invention
The unidirectional intervertebral fusion fixture of cervical vertebra described in the utility model, as depicted in figs. 1 and 2, this device comprises the screw fixed part 1 of front end and the intervertebral fusion portion 4 of rear end; The arranged on left and right sides of screw fixed part arranges symmetrical screw 3 respectively, and these screws 3 are that intervertebral fusion portion 4 is fixed on the soleplate of the lower joint vertebral body of dislocation Minor articulus by inclination so that screw by screw 3; Locking device 2 is provided with between these screws 3, for the screw inserting screw 3 is pinned in order to avoid screw is deviate from, so that intervertebral fusion portion 4 is applicable to being placed on cervical bilateral dislocation and is resetted between rear two vertebral bodys, for the intervertebral disc extractd in alternative cervical operation.
In preferred specific embodiment, the incline direction of screw becomes the angle of 30 degree with fusion device.
According to above-mentioned design principle, the product of a series of different model can be prepared for the concrete data of the individual variation of different patient, in operation, select different model to carry out coupling as the case may be use.
Claims (2)
1. the unidirectional intervertebral fusion fixture of cervical vertebra, is characterized in that, described device comprises the screw fixed part of front end and the intervertebral fusion portion of rear end; The arranged on left and right sides of described screw fixed part arranges symmetrical screw respectively, and described screw is that described intervertebral fusion portion is fixed on the soleplate of the lower joint vertebral body of dislocation Minor articulus by inclination so that screw by described screw; Locking device is provided with between described screw, for the screw inserting described screw is pinned in order to avoid screw is deviate from, so that described intervertebral fusion portion is applicable to being placed on cervical bilateral dislocation and is resetted between rear two vertebral bodys, for the intervertebral disc extractd in alternative cervical operation.
