Description
Technical field
What the present invention relates to is a kind of Anti-retreat stable type posterior cervical single open-door plate nail system, is a kind of surgical intervention apparatus that is used for the treatment of serious cervical spinal stenosis and ossified posterior longitudinal ligament.
Background technology
Cervical spinal stenosis is onset symptoms mainly with extremity stolidity, twinge greatly, often, from arm part, increases the weight of gradually, and gradually occurs that both hands grip declines, hold thing incessantly, chest zonesthesia, there is as step on the sensation of Cotton Gossypii heap in lower limb, the shakiness of standing, walk, gait is heavy, starting difficulty.There is lower limb spasm, paralysis, constipation, urinary incontinence in severe one.
Traditional open-door laminoplasty expands laminoplasty, obstinate axle symptom, the side of opening the door canalis spinalis restenosis and the corresponding sections pressurized due to closing the door after operation, and screw slippage goes out the problems such as steel plate and is perplexing doctor and patient always.
Summary of the invention
The object of the invention is for above-mentioned weak point, a kind of Anti-retreat stable type posterior cervical single open-door plate nail system is provided, it is simple in structure, easy to use, screw thread afterbody is provided with screw grooves, in the use procedure of single open-door plate, screw can not exit single open-door plate bolt hole, play anti-back function, single open-door plate feet is provided with anti-slop serrations simultaneously, single open-door plate is carried in motor process and be well attached on vertebral plate truncation surface, play anti-skidding effect, effectively solve better above traditional cervical spinal stenosis problem running into of performing the operation.
A kind of Anti-retreat stable type posterior cervical single open-door plate nail system is to take following technical scheme to realize:
A kind of Anti-retreat stable type posterior cervical single open-door plate nail system comprises single open-door plate and screw.On single open-door plate, be provided with screw hole, be provided with single open-door plate bolt hole step in screw hole bottom, single open-door plate top is provided with feet, and feet is provided with anti-slop serrations; Screw thread afterbody is provided with screw grooves, plays anti-back effect.
On described single open-door plate, be at least provided with 2 screw holes.
Described screw adopts titanium alloy material to make.
Described single open-door plate adopts pure titanium steel plate material to make.
Operation principle
When a kind of Anti-retreat stable type posterior cervical single open-door plate nail system uses, after the sections of cervical spinal stenosis utilizes rongeur that vertebral plate is sectioned, select suitable single open-door plate, single open-door plate is fixed in the middle of the cervical vertebra plate sectioning with screw, strut the vertebral plate being sectioned, the side that prevents from opening the door is closed the door.In the time that screw thread afterbody screw grooves coordinates with single open-door plate bolt hole step, match owing to being provided with screw thread, in the use procedure of single open-door plate, screw can not exit single open-door plate bolt hole, play anti-back function, single open-door plate feet is provided with anti-slop serrations simultaneously, single open-door plate is carried in motor process and be well attached on vertebral plate truncation surface, plays anti-skidding effect.
A kind of Anti-retreat stable type posterior cervical single open-door plate nail system advantage
A kind of Anti-retreat stable type posterior cervical single open-door plate nail system is reasonable in design, simple in structure, easy to use, in the time that screw thread afterbody screw grooves coordinates with single open-door plate bolt hole step, match owing to being provided with screw thread, in the use procedure of single open-door plate, screw can not exit single open-door plate bolt hole, play anti-back function, single open-door plate feet is provided with anti-slop serrations simultaneously, single open-door plate is carried in motor process to be well attached on vertebral plate truncation surface, play anti-skidding effect, can solve obstinate axle symptom after traditional operation, canalis spinalis restenosis and the corresponding sections pressurized of the side of opening the door due to closing the door, screw slippage goes out the problems such as steel plate.
