Description
Technical field
The present invention relates to the field of medical instrument technology, specifically, being related to a kind of backbone coronary sinus retroperfusion connector.
Background technology
The internal fixation method of pedicle nail joint stud has been widely used for backbone degenerative disorders, spine fracture etc. one
The sick and wounded treatment of series is being rebuild spinal stability, is being promoted in bone grafting fusion and recovery backbone sequence, achieving good effect
Fruit.It is that bilateral pedicle screw-rod is fixed under normal circumstances, the stud that bilateral can be connected with connector intermediate when necessary, further
Increase intensity (Fig. 1).Unilateral pedicle screw-rod fixation also has the case where use, but its intensity is to be weakened certainly, not as
It is conventional to use.
Coronary sinus retroperfusion is the screw for fixing adjacent segment Minor articulus in spinal operation, is mostly other amalgamation modes
It is auxiliarily fixed, intensity is weaker than nail pedicle fix, is not used alone generally, and Minor articulus saboteur can not also use.Operation
In the process, coronary sinus retroperfusion generally enters from the vertebral plate of offside, prominent across lower articular, and adjacent lower articular is dashed forward and is fixed on
Together.Usually bilateral is fixed, intermediate occasionally to have using connector.It can be used for backbone open surgery, but more often see vertebral column minimally invasive
Operation.
Conventional installation methods need to be placed in vertebra section bilateral pedicle nail up and down, cooperation stud locking connection at present.The connection side
Method needs vertebra section bilateral to be placed in pedicle nail, but for unilateral disc herniation, unilateral Spondylolysis and other need
The patient of unilateral side decompression, the strong side structure of exposure are placed into pedicle nail, are bound to cause a wide range of stripping of strong pleural muscle meat, increase wound
Wound and amount of bleeding, delayed recovery time；Meanwhile more merging pedicle nails are also one additional to patient and social medical expenses
Burden.It is such as followed closely using percutaneous cervical arc root and complicated for operation, time-consuming and expensive.In addition for offside pedicle of vertebral arch dysplasia, no
It is suitble to the special case of merging pedicle nail, and first nail of setting fails, screw way destroys the trouble that can not be seriously placed in pedicle nail again
Person, conventional method then cannot be solved effectively.Certainly unilateral side nail pedicle fix also has use, but its intensity is to be subtracted certainly
It is weak, not as conventional use.
Then there is coronary sinus retroperfusion to be used in combination with unilateral pedicle screw-rod, be placed in using with unilateral pedicle screw-rod homonymy
Coronary sinus retroperfusion, the upper vertebra section inferior articular process of fixed offside and the next centrum processus articular superior (Fig. 2).It can be good in solution
Drawback is stated, wound is both reduced, the exposure of bilateral muscle is avoided, and increased than unilateral pedicle nail intensity, also reduces expense
With.But it is not associated between current coronary sinus retroperfusion and pedicle screw-rod, intensity still dislikes insufficient.
Yet there are no for connecting coronary sinus retroperfusion and pedicle screw-rod, have excellent in strength, convenient for surgical procedure and
Device of simple structure and low cost.
