Description
Technical field
The present invention is to be applied to outside clinical orthopaedics, a kind of lumbar vertebra compression fracture way of escape Wicresoft fixing skin of nail rod reset system, belongs to medical device.It is to apply to human body thoracolumbar vertebrae posterior longitudinal ligament completely unstable fracture closed reduction internal fixation apparatus.The application of this equipment, is i.e. conducive to alleviating operation wound, advantageously reduces again operation and hospital stays.
Background technology
The Therapeutic Method of lumbar vertebra compression fracture, in development, varies.Roy-Camille etc. are fixing in 1961 start to apply pedicle screw and steel plate to carry out lumbar vertebra compression fracture.Through semicentennial clinical practice and multicenter study analysis, it is believed that Pedicle Screw Fixation For Treatment of Thoracolumbar Fracture is effective.Fracture or dislocation apparatus also to pedicle screw-rod system evolution by nail-plate.Operation wound improves also with internal fixation device and surgical proficiency level improves and reduces.
At present, pedicle screw-rod system has become the main flow of Thoracolumbar disk unstable fracture Posterior fixation treatment.Pedicle screw-rod system can provide stable interior fixing for lumbar vertebra compression fracture, controls the revolving force of fracture well, effectively struts the vertebral body of compression, recovers Stability Analysis of Structures between vertebral body.
Along with the proposition of BO theory, fix in unstable lumbar vertebra compression fracture and reset to closure reset transformation by opening, in order to alleviate soft tissue injury.But, it is thus achieved that and maintain Thoracolumbar disk closed reduction be extremely difficult.The internal fixation apparatus being correlated with now occurs, but still haves much room for improvement.We devise the system that resets outside a kind of lumbar vertebra compression fracture way of escape Wicresoft fixing skin of nail rod, and the most beneficially lumbar vertebra compression fracture way of escape Wicresoft nail-stick system way of escape Wicresoft nail-stick system is inserted, the most beneficially lumbar vertebra compression fracture Guan Bi distraction reduction and fixing.Thus, alleviate way of escape Wicresoft nail-stick system operation wound, reduce operating time.
Summary of the invention
The invention aims to overcome the deficiency of existing lumbar vertebra compression fracture fracture or dislocation equipment, it is provided that in a kind of effective Wicresoft, fix auxiliary appliance.Native system beneficially lumbar vertebra compression fracture way of escape Wicresoft nail-stick system is inserted, and the most beneficially lumbar vertebra compression fracture closes distraction reduction and fixes.Improve the accuracy that lumbar vertebra compression fracture way of escape Wicresoft internal fixation nail bar system pitman is inserted, reduce wound when pitman is inserted, and effectively strut the vertebral body of compression, recover the height of vertebral body.It is Thoracolumbar disk unstable fracture, the optimum selection of the complete patient of posterior longitudinal ligament.
To achieve these goals, the present invention adopts the following technical scheme that:
The T-shaped fixing bar of reset system outside a kind of lumbar vertebra compression fracture way of escape Wicresoft fixing skin of nail rod, it is characterized in that T-shaped is fixed bar far-end and is provided with fixing nut (1), near-end is provided with fixed handle (2) and stops cross bar (3), and fixed handle is movable and mutually embedding with stop cross bar.Above-mentioned each scantling is: fixing nut diameter 6-8mm, thickness 2-4mm, is connected with fixing bar；Stopping cross bar length 10-24mm, diameter 6-10mm, stage casing has a circular hole and fixed handle moving phase embedding；T-shaped fixes pole length 10-100mm.
The operation principle of the present invention is: after anaesthetizing successfully, and patient takes prone position on Orthopedic operation bed, routine disinfection drape." C-arm " Fluoroscopy location hinders vertebra, inserts guide pin through neighbouring vertebral body pedicle of vertebral arch superior articular process and transverse process intersection, cuts entrance skin 2cm, insert ductal ectasia, and place hollow screw tap along guide pin, and carrying out tapping, application hollow pedicle crow-bar fixed reset sleeve is followed closely with long-tail pedicle.Long-tail pedicle nail is implanted through guide pin.Remove pedicle nail bottle opener, insert fixing bar, select suitable angle distraction reduction bolt to strut U-shaped hollow long-tail pedicle nail, reseting fracture.Rotated arm inserts T-bar guide pin in pedicle nail tail, inserts T-bar through this guide pin.T-bar main rod pre-bending as required.Spacer controls the main rod degree of depth.It is screwed into the head of a nail respectively and locks.Go to allowance for bark outer reset system.Fracture pedicle nail long-tail and T-shaped handle.Check dressing apparatus, close otch and wrap up.Omnidistance operation under " C-arm " monitors.
Profitable fruit: one, safety: percutaneous is inserted pedicle nail and be need not otch and appear paraspinal muscle.Omnidistance operation under " C-arm " monitors, inserts guide pin through hindering vertebra neighbouring vertebral body pedicle of vertebral arch superior articular process with transverse process intersection, will not injured nerve, blood vessel.Operating outside reset system percutaneous outside the fixing skin of lumbar vertebra compression fracture way of escape Wicresoft nail rod, angle distraction reduction device monitors lower operation in " C-arm ", will not excessively strut vertebral body.The unimodal blade in double angles, in the guided Percutaneous and the paraspinal muscle extremely nail U-shaped groove of tail of turning arm, passes through through lamina surface, does not enter canalis spinalis and intervertebral foramina.Any organizational structure will not be damaged.
Two, effectiveness: having at present multiple lumbar vertebra compression fracture way of escape Wicresoft system on the market, clinical practice is extensive.Native system improves on the basis of existing internal fixation device, it is adaptable to Thoracolumbar disk unstable fracture, and the patient that posterior longitudinal ligament is complete.Outside the fixing skin of lumbar vertebra compression fracture way of escape Wicresoft nail rod, reset system improves the accuracy that lumbar vertebra compression fracture way of escape Wicresoft internal fixation nail bar system pitman is inserted, and reduces wound when pitman is inserted, and effectively struts the vertebral body of compression, recovers the height of vertebral body.Thus, alleviate way of escape Wicresoft nail-stick system operation wound, reduce operating time.Be conducive to patient's early recovery.
It is an advantage of the current invention that: the present invention provides fixing bar to be designed with the fixing sleeve of prevention when beneficially compressed vertebral struts and follows closely sliding with long-tail hollow pedicle, affects compressed vertebral and effectively struts.
