Description
Technical field
This utility model relates to orthopaedics implant technical field, especially a kind of zero incisura anterior cervical vertebrae Invasive lumbar fusion device.
Background technology
Current intervertebral disc of cervical vertebra degenerated disease, spinal canal stenosis, the past Fusion failure, pseudarthrosis etc. are common clinically cases.Therapeutic method of surgery is mainly at diseased region and implants cervical steel plate and common cervical fusion cage at present.But product mostly in the market is common cervical fusion cage, its stability is bad, needs to be used in conjunction with cervical steel plate simultaneously, and during operation, opening is large, complex operation, and operating time is long, and price is high.
Utility model content
The technical problems to be solved in the utility model is: overcomes the deficiencies in the prior art, a kind of zero incisura anterior cervical vertebrae Invasive lumbar fusion device is provided, and good biocompatibility, easy and simple to handle.
This utility model solves the technical scheme that its technical problem adopts: a kind of zero incisura anterior cervical vertebrae Invasive lumbar fusion device, there is fusion device body, described fusion device body comprises and is positioned at anterior fusion part and the lock part that is positioned at rear portion, described fusion device body is made into integration by PEEK material, described surface of merging part arranges projection, described lock part offers the screwed hole that 3 longitudinal directions run through and tilt, and the incline direction of screwed hole in the middle of being wherein positioned at is contrary with the incline direction of the screwed hole of its both sides.
Further, described fusion device body and lock screw are used in conjunction with, and by lock screw, directly fusion device body and bone are fixed.
Further, the front end of the fusion of described fusion device body part is arc.
Further, the projection of described fusion part surface is many row's order of a permutation ladder inclined teeth.
The beneficial effects of the utility model are: fusion device of the present utility model selects PEEK material to be made into integration, simple for production, good biocompatibility, lonizing radiation penetrable and assessment osteogenesis situation, by lock screw locking, be beneficial to initial stage and long-time stability, this utility model only needs the little otch technology in the place ahead just implantable, and zero incisura reduces dysphagia and the curing risk of adjacent segment.
This utility model can be used as treatment intervertebral disc of cervical vertebra degeneration and merges Radiculopathy symptom, spinal canal stenosis, the past Fusion failure, the interior fixing therapeutic appliance in the symptom operations such as pseudarthrosis.

The specific embodiment
By reference to the accompanying drawings this utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with this utility model.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of zero incisura anterior cervical vertebrae Invasive lumbar fusion device, there is fusion device body 1, fusion device body 1 comprises the lock part 12 that is positioned at anterior fusion part 11 and is positioned at rear portion, fusion device body 1 is made into integration by PEEK material, the surface of merging part 11 arranges projection, and lock part 12 offers the screwed hole 13 that 3 longitudinal directions run through and tilt, and the incline direction of screwed hole 13 in the middle of being wherein positioned at is contrary with the incline direction of the screwed hole of its both sides 13.Fusion device body 1 is used in conjunction with lock screw 2 as shown in Figure 5, by lock screw 2, directly fusion device body 1 and bone is fixed.The front end of the fusion part of fusion device body 1 is arc.The projection that merges part 11 surfaces is many row's order of a permutation ladder inclined teeth.
Nature anatomic form is partly followed in the fusion of fusion device, makes bone and fusion device close contact, can recover intervertebral height and cervical vertebra is anteflexion.Step inclined tooth increases primary stability, fusion device selects PEEK material to be made into integration, simple for production, good biocompatibility, lonizing radiation penetrable and assessment osteogenesis situation, by lock screw locking, be beneficial to initial stage and long-time stability, this utility model only needs the little otch technology in the place ahead just implantable, and zero incisura reduces dysphagia and the curing risk of adjacent segment.
3 screwed holes of this utility model design, the incline direction of screwed hole in the middle of being wherein positioned at is contrary with the incline direction of the screwed hole of its both sides, the lock screw that screwed hole in the middle of being positioned at inserts and top bone or inferior bone are fixed, the lock screw that the screwed hole of its both sides inserts is correspondingly fixed with inferior bone or top bone, installation is fixing simple and easy, and good stability.
This utility model can be used as treatment intervertebral disc of cervical vertebra degeneration and merges Radiculopathy symptom, spinal canal stenosis, the past Fusion failure, the interior fixing therapeutic appliance in the symptom operations such as pseudarthrosis.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to claim scope.
