Abstract
The utility model particularly relates to a fuse ware between zero notch anterior cervical spine awl, including fusing ware body and locking screw, it is taper spatial structure to fuse the ware body, it respectively is equipped with first screw and second screw to fuse ware body front end left and right sides symmetry, it still is equipped with the third screw to fuse ware body front end intermediate position, the axial lead of first screw and second screw with the angle range who fuses ware body horizontal cross -section is 38~41, the axial lead of third screw with the angle range who fuses ware body vertical cross -section is 30~50. The utility model provides a nature dissection form is followed to the tapering part that fuses the ware body, makes the bone and fuses ware in close contact with, retrieval intervertebral height and cervical vertebra anteflexion, the locking screw uses through the ground cooperation of specific angle, does benefit to initial stage and long term stability, alright the implantation of the little incision in the place ahead technique, and easy operation, it possesses the advantage that the cervical vertebra fuses ware and anterior cervical spine steel sheet simultaneously, and surgery effect is better.
Description
Technical field
The utility model belongs to orthopaedics implant technical field, is specifically related to a kind of zero incisura anterior cervical vertebrae vertebrae mixer.
Background technology
It is currently used for clinical treatment intervertebral disc of cervical vertebra retrogression pathological changes, spinal canal stenosis, previously Fusion failure, during pseudarthrosis, mostly is common cervical vertebral fusion cage and is used alone, but poor stability；Or anterior plate fixation and common cervical vertebral fusion cage are used in combination, during two kinds of product operations, opening is big, complex operation, and operating time is long, and operation price is high.
Utility model content
For above-mentioned problem of the prior art and non-foot point, the utility model provides zero incisura anterior cervical vertebrae vertebrae mixer, and the utility model product tapered portion follows nature anatomic form, makes bone be in close contact with fusion device, can recover intervertebral height and cervical vertebra is anteflexion.
For solving the problems referred to above, adopted the technical scheme that:
Zero incisura anterior cervical vertebrae vertebrae mixer, including fusion device body and lock screw, described fusion device body is taper stereochemical structure, it is cavity in the middle part of described fusion device body, on described fusion device body, outer lower face surface is provided with teeth structure, the left and right sides, described fusion device body front end symmetry is respectively provided with the first screw and the second screw, centre position, described fusion device body front end is additionally provided with the 3rd screw, the axial line of described first screw and the second screw is 38 °～41 ° with the angular range of described fusion device body horizontal cross-section, the axial line of described 3rd screw is 30 °～50 ° with the angular range of described fusion device body vertical cross-section；Described lock screw is fixed together with described fusion device body by described first screw, described second screw and described 3rd screw, and described lock screw one end is provided with screw.
Preferably, described teeth even structure is distributed on described fusion device body on outer lower face surface.
Preferably, described lock screw includes the first teeth portion and the second teeth portion, described lock screw is fixed together with described fusion device body with described first screw, described second screw and described 3rd screw by the second teeth portion, and the space width of described first teeth portion is more than the space width of the second teeth portion.
Preferably, described lock screw includes that spiral shell tip, described spiral shell tip are provided with breach.
Preferably, the material of described fusion device body is PEEK material, i.e. polyether-ether-ketone.Fusion device body selects PEEK Biocompatibility good, radioactive ray can penetrate and assess the situation of bone uptake, and lock screw locking is beneficial to initial stage and long-time stability, and the little notch technology in front is the most implantable, simple to operate, it is provided simultaneously with the advantage of cervical vertebral fusion cage and anterior plate fixation.
Use technique scheme, acquired provide the benefit that:
Zero incisura anterior cervical vertebrae vertebrae mixer in the utility model, the tapered portion of fusion device body is followed nature anatomic form, is made bone be in close contact with fusion device, can recover intervertebral height and cervical vertebra is anteflexion；Lock screw by the first screw, the second screw and the 3rd screw special angle ground with the use of, being beneficial to initial stage and long-time stability, the little notch technology in front is the most implantable, simple to operate, it is provided simultaneously with the advantage of cervical vertebral fusion cage and anterior plate fixation, and surgical effect is more preferably.
