Abstract
The invention relates to a zero-notch anterior cervical intervertebral fusion cage, which is provided with a fusion cage body, wherein the fusion cage body comprises a fusion part positioned on the front part and a locking part positioned on the back part; the fusion cage body is integrally made of a PEEK material; bumps are arranged on the surface of the fusion part; the locking part is provided with three threaded holes which are penetrated in the longitudinal direction and are inclined; the inclination direction of the threaded hole positioned in the middle is opposite to the inclination directions of the threaded holes in both sides. The fusion cage body is used together with a locking screw, and is directly fixed with a bone by using the locking screw. The zero-notch anterior cervical intervertebral fusion cage is integrally made of the PEEK material, is easy and convenient to make, and has high biocompatibility. Initial and long-term stability is facilitated by locking through the locking screw. The zero-notch anterior cervical intervertebral fusion cage can be implanted through a front small incision technique, and the difficulty in swallowing and the risk of curing of adjacent segments are lowered through zero notch.
Description
Technical field
The present invention relates to orthopaedics implant technical field, especially a kind of zero incisura anterior cervical vertebrae Invasive lumbar fusion device.
Background technology
Intervertebral disc of cervical vertebra degenerated disease at present, spinal canal stenosis, previously 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 when operation, opening is large, complex operation, and operating time is long, and price is high.
Summary of the invention
The technical problem to be solved in the present invention 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.
The technical solution adopted for the present invention to solve the technical problems is: 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 directly fusion device body and bone are fixed by lock screw.
Further, the front end of the fusion part of described fusion device body is arc.
Further, the projection of described fusion part surface is many row's order of a permutation ladder inclined teeth.
The invention has the beneficial effects as follows: fusion device of the present invention selects PEEK material to be made into integration, simple for production, good biocompatibility, lonizing radiation penetrable and assessment osteogenesis situation, be beneficial to initial stage and long-time stability by lock screw locking, the present invention only needs the little otch technology in front just implantable, and zero incisura reduces dysphagia and the curing risk of adjacent segment.
The present invention can be used as treatment intervertebral disc of cervical vertebra degeneration and merges Radiculopathy symptom, spinal canal stenosis, previously Fusion failure, the interior fixing therapeutic appliance in the symptom operations such as pseudarthrosis.

Detailed description of the invention
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
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, directly fusion device body 1 and bone is fixed by lock screw 2.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.
The fusion part of fusion device is followed nature anatomic form, 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, be beneficial to initial stage and long-time stability by lock screw locking, the present invention only needs the little otch technology in front just implantable, and zero incisura reduces dysphagia and the curing risk of adjacent segment.
The present invention designs 3 screwed holes, 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.
The present invention can be used as treatment intervertebral disc of cervical vertebra degeneration and merges Radiculopathy symptom, spinal canal stenosis, previously Fusion failure, the interior fixing therapeutic appliance in the symptom operations such as pseudarthrosis.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, must determine its technical scope according to claim scope.
