Description
Technical field
The utility model is specifically related to a kind of novel cervical vertebrae front pedicle nail titanium cage.
Background technique
Anterior cervical vertebrae Subtotal vertebrectomy for treatment often rebuilds cervical stability with fixing in titanium plate screw combination titanium cage at present,
Preceding road titanium plate screw mainly plays fixed function, and titanium cage mainly plays a supportive role, but has the disadvantage in that 1. titanium cages itself and lack
Stability mechanism, the fixation failures such as titanium cage sinks, titanium plate screw shifts are commonplace.2. bent with cervical vertebra after preceding road titanium cage support
Degree is not consistent, and rear convex orthopedic effect is poor.3. because titanium plate screw is irritating to throat tissue such as oesophagus tracheae, with dysphagia or
The complication such as postoperative foreign body sensation.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of novel cervical vertebrae front pedicle of vertebral arch
Titanium cage is followed closely, achieving the purpose that enhance titanium cage stability, avoiding postoperative complications and meeting cervical curvature demand.
The purpose of this utility model is achieved by the following technical programs.
A kind of novel cervical vertebrae front pedicle nail titanium cage includes titanium cage ontology, has pedicle of vertebral arch on the titanium cage ontology
Nail hole, the pedicle of vertebral arch nail hole inward turning enter to be fixed with pedicle screw, and the titanium cage ontology upper and lower sides are equipped with angled pad
Piece is assembled on titanium cage ontology by splicing with the angled gasket and forms one, is opened on the angled gasket of band
There is lock hole, centrum screw is fixed in the lock hole.
Preferably, the body part with the angled gasket has 3 ° of tilt angle and surface has protrusion sawtooth,
The body part of the gasket further includes an inclination lobe, and the tilt angle of the inclination lobe is 45 °, centrum screw orientation and water
Flat is in 25 ° of angles.
Preferably, the lock hole is located on inclination lobe.
Preferably, the pedicle screw is fixed using driving in the wrong direction for being placed in pedicle of vertebral arch nail hole.
Preferably, the pedicle nail hole is located at the two sides outer rearward of titanium cage ontology.
Preferably, the pedicle screw is hollow setting.
The beneficial effects of the utility model are: 1. increase titanium cage stability.It is given on titanium cage plus with pedicle screw solid
It is fixed, greatly enhance titanium cage stability；2. integrating hypocentrum screw on decompression phase above and below titanium cage to fix, titanium plate is saved, is reduced
Interior fixed volume reduces interior fixation and makes sure to keep in mind, reduces front tissue stimulation, avoid postoperative complications；3. increasing at upper and lower titanium cage both ends
Add band angle gasket, reduce stress between titanium cage and terminal plate of vertebral body, cervical curvature can be corrected while increasing contact area, met
Cervical curvature demand.Completely new pedicle nail titanium cage system design, while increasing stability fixed in anterior cervical vertebrae,
Titanium cage is reduced as far as possible to sink, shift, and avoids the complication such as fixation failure.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to
It explains the utility model, is not used to limit the utility model.
Embodiment
As shown in Figs 1-4, a kind of novel cervical vertebrae front pedicle nail titanium cage includes titanium cage ontology 1, the titanium cage sheet
Pedicle of vertebral arch nail hole 11 is had on body 1, is screwed in the pedicle of vertebral arch nail hole 11 and is fixed with pedicle screw 12, the titanium cage ontology 1
Upper and lower sides are equipped with angled gasket 13, are assembled on titanium cage ontology 1 and are formed by splicing with the angled gasket 13
Integrally, it is provided with lock hole 14 on the angled gasket 13 of band, is fixed with centrum screw 15 in the lock hole 14, have angle
The body part of the gasket 13 of degree has 3 ° of tilt angle and surface has protrusion sawtooth 132, and protrusion sawtooth 132 plays increasing
The effect of stiff stability, the body part of the gasket further include an inclination lobe 131, the tilt angle of the inclination lobe 131
It is 45 °, centrum screw orientation and level are in 25 ° of angles, and the lock hole 14 is located on inclination lobe 131, the pedicle screw
12 are placed in pedicle of vertebral arch nail hole 11 fixed using driving in the wrong direction, and the pedicle of vertebral arch nail hole 11 is located at rearward outer the two of titanium cage ontology 1
Side, the pedicle screw 12 are hollow setting.
Operation instruction:
The decompression of anterior cervical vertebrae Subtotal vertebrectomy is carried out first, and method is compared with technology.After the completion of decompression, premenstrual road vertebral arch
Root is placed in guide pin, then removes on part reduced pressure segment before a centrum that the inclination of upper limb New bone formation is prominent before lower edge and next centrum
Tooth.Then decompression segmental height is measured, selects the titanium cage of suitable length, and be assembled into one with angled gasket 13 with upper and lower
Body.By assembled interior fixed titanium cage merging and guide pin is passed through to the nail hole reserved on titanium cage, upper lower gasket is placed in pre- in advance
Making sure to keep in mind for staying is interior, then along the fixed titanium cage of guide pin merging pedicle screw 12, is most placed in centrum screw 15 through upper and lower gasket afterwards, finally
It completes to fix.
The beneficial effects of the utility model are: 1. increase titanium cage stability.It is given on titanium cage plus with pedicle screw solid
