Description
Technical field
The present invention relates to a kind of medical machinery, specifically a kind of bone grafting device of pedicle row Vertebral graft.
Background technology
Breast waist section is the turning point between movable lumbar vertebra and fixed thoracic vertebra, body activity stress concentration in this, and in spinal bone
Compromise lumbar vertebra compression fracture is most common classification of fracture, and the fixed fusion of posterior Pedicle nail is the most normal of current diagnosis and treatment lumbar vertebra compression fracture
See modus operandi, but the long segment of Posterior fixation fusion is fixed and can easily be occurred in the interior activity for limiting breast waist section in a big way
Spinal motion segment is lost and Adjacent segment degeneration.It is current many using Jing way of escape spinal canal decompressions, neighbouring vertebra pedicle screw
The traditional therapy of interior fixation, but the later stage there are problems that in it is fixed loosen fracture, Loss of correction and.
In recent years, as the improvement of a series of modus operandi, clinical research show, hinder vertebra Vertebral graft+Jing and hinder vertebra
In pedicle screw fixation can effectively recover to hinder vertebra height, eliminate the reduction of the fracture after " eggshell " phenomenon, effectively prevent Delayed onset
The generation of vertebral body kyphosis deformity and Unstable internal fixation.But as current bone grafting instrument can not appropriately control bone grafting direction, plant
To affect to hinder vertebra and put nail after bone, theoretically, if can in surface observation bone grafting front opening direction, bone grafting tool external diameter compared with
It is little do not interfere with bone grafting after hinder vertebra the operation effect put nail, can will ensure significantly lumbar vertebra compression fracture internal fixation operation of cutting and resetting
Really.

After the completion of sleeve is retreated at 3cm scales（I.e. the front end of pilot sleeve is located at pedicle of vertebral arch and vertebral body boundary level）, now again
To fill up Cranial defect in the vertebral body caused because of bone grafting process, 1/3 position in can making transplanting particulate cancellous bone before vertebral body makes bone grafting
Vertebra of falling ill obtains the support of more firm stable；
（3）In the present invention, the opening angle of the tilted conical end of pilot sleeve is 50 ~ 60 °, the length of the dip section of bone grafting bar
Lower segment length of the degree more than the pilot sleeve, it is ensured that in bone grafting, spongy bone are implanted into by the opening direction of pilot sleeve
The accuracy of bone grafting in vertebral body, is further lifted, " eggshell " phenomenon after the reduction of the fracture is eliminated after bone grafting, is recovered vertebral bone resistance to compression
Ability, effectively prevents the generation of Delayed onset vertebral body kyphosis deformity；
（4）In the present invention, the end of the dip section of bone grafting bar caves inward to form concave surface, when bone grafting bar is advanced, spongy bone
Bone grafting bar will not be made to be easier particulate cancellous bone to be pushed in vertebral body by the side leakage of bone grafting bar；
（5）In the present invention, the external diameter of pilot sleeve is two kinds of specifications of 6.0 mm or 5.5 mm, and bone grafting tool external diameter is less not
That hinders vertebra after affecting bone grafting puts nail, can will ensure significantly the surgical effect of lumbar vertebra compression fracture internal fixation operation of cutting and resetting,
Strengthen the intensity of Fracture internal fixaiion, it is convex abnormal after more accurate correction.
