Description
Technical field
The present invention relates to medical equipment technical field, in particular to followed closely on a kind of pedicle nail with gravity needle protractor
Device.
Background technique
Unstable spine, fracture dislocation of spine are orthopaedics common diseases, often show themselves in that spinal lesion position local pain,
Rediating Pain, the numbness etc. of corresponding sacrum innervation region.Serious symptom person's non-operative treatment curative effect is not good enough, seriously affects the life of people
Living and work.Spinal fusion and internal fixation can remove the abnormal movement of lesion segment, effectively correct deformity of spine, rebuild backbone
Stability.Pedicle merges Internal fixation technology because its is curative for effect, fusion rate is high, and clinical application is the most extensive.However, by
In backbone different parts pedicle of vertebral arch size, introversion and end to end the angle inclined is clinical pedicle of vertebral arch often occurs often because of people, different because of centrum
Nail set nail position it is not good enough, be not achieved operation purpose while, may also bring relevant complication, part complication even causes
Life property.
There is the safety of its general character to set nail range though each position pedicle nail of backbone sets nail, each centrum pedicle of vertebral arch sets the peace of nail
Gamut tolerance is universal less < 10 °, some tolerances only in very low range < 2-5 °, while clinically occur making a variation and beyond general character
The case of safe range is many.The design that device is followed closely on traditional pedicle nail, due to being affected by operator's subjective estimation,
Determine that it is unable to ensure the precision in the direction and angle of setting nail at all, different operative doctors, the result for setting nail may phase
Difference is very remote.It is partially outer to set nail, then wears out pedicle of vertebral arch lateral wall, holding power is caused to decline, postoperative easy nail pulling；It is partially interior to set nail, then may be used
Spinal cord and nerve root are damaged, pain, stolidity that nerve root dominates region gently then occurs, it is heavy then can lead to paraplegia or even dead
It dies.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides follow closely on a kind of pedicle nail with gravity needle protractor

Further, the protractor measurement range be 0-360 °, precision be 5 ', the protractor and gripping handle one at
Type.
Further, the threaded sleeve is equipped with outer tooth far from gripping handle end excircle, and the outer tooth is suitable for unidirectional vertebra
Nut nail, Universal vertebra arch root screw, long-tail pedicle nail, short-tail pedicle nail.
Further, the T-type core bar, hexagonal core bar, vertebral pedicle puncture core bar and quick mounting type handle are hollow structure, can
Guide pin is positioned for being inserted into.
The invention has the benefit that
Protractor of the present invention is the integrated design with gripping handle, and can surround together with gripping handle and follow closely device on pedicle of vertebral arch
Core bar is in 360 ° of rotations, keeping protractor surface and in the case where horizontal plane, protractor pointer due to gravity effect,
It remains vertically downward direction, by dial scale, can be read and adjust required angle of pedicle screw.It is carried on gripping handle
Gravity needle protractor, measurement range be 0-360 °, 5 ' of precision.The design so that pedicle nail merging can precisely, quantization, and
Not using patient's naked eyes subjective estimation as foundation, nail deviation is set caused by largely reducing because of subjective reason.Upper nail handle
Designed with core bar for quick mounting type, single handle can simultaneously mating T-type core bar and hexagonal core bar, be respectively used to unidirectional pedicle nail and
Universal vertebra arch root screw.Threaded sleeve is independent accessory, the design of outer tooth can lead to unidirectional, universal, long-tail, short-tail pedicle nail
With, it can be screwed by the interior tooth with pedicle screw around 360 ° of core bar rotations and strong holding is carried out to pedicle nail fix,
Facilitate its merging, the length of core bar is squeezed T-type inserted link and fit in adjustment length in the limit hole of different location, made by hand push
With conveniently.
