Abstract
This utility model relates to technical field of medical instruments, discloses a kind of spinous process fixation device.This spinous process fixation device is formed by two spinous process fixation device bodies in " 7 " font fastening that is mutually inverted, described spinous process fixation device body is made up of horizontal edge and longitudinal edge, a top of described horizontal edge is provided with adjustment hole, another top is provided with fixing hole, and described longitudinal edge is provided with at least 2 fixing holes.In use, spinous process under occlusion is placed into patient's pedicle of vertebral arch place, with the horizontal edge of spinous process fixation device body, it is first located, the fixing elasticity of spinous process is regulated by adjustment hole, install screw, the longitudinal edge of spinous process fixation device body is separately fixed at the both sides of vertebra, the spinous process under occlusion is just fixed on vertebra safely and reliably again.Postoperatively not easily to be shifted, the phenomenon such as come off, reliability is high, effectively alleviates the misery of spinal cord spinal column sufferer, and this utility model structure is simple, easy to operate, reliability is high, can reuse, and reduces the financial burden of patient.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of dependable performance, convenient fixing, the spinous process fixation device that can reuse.
Background technology
When patient does intraspinal tumor excision, doctor directly excises spinous process and vertebral plate thus exposes tumor, and only sew up spinal meninges after tumor resection, spinal column is not fixed, and does not also also receive spinous process and vertebral plate.Find that the patient removed for long segment (being greater than 3) spinous process and vertebral plate there will be campylorrhachia, spinal cord rear portion and the complication such as muscle adhesion, nerve root pain the later stage by Long-term clinical observation.Along with the development of medical skill, international academic community starts to inquire into the postoperative fixing problem of spinal cord spinal column, mainly concentrate on spine nail rod fixing+spinal fusion on, in long segment spinal operation, really achieve good effect.But, because the expense that immobilization material is high makes popularization be subject to certain restrictions and queries, especially to the operation of intraspinal tumor within 3 sections, vertebral plate spinous process fixedly seem not essential, but after operation in patients, nerve root pain is but to evade the question.Some neurosurgery expert attempts using brace that the complete vertebral plate spinous process taken off is fixed on pedicle of vertebral arch, reach the object of anatomical reduction, there is obvious effect through observing for alleviation nerve root pain, and the generation of vertebral deformation deformity can be prevented to a certain extent.Hospitals at Present does not fix the equipment special of vertebral plate spinous process, fix spinous process with brace so after surgery to seem and very bother effort, and spinous process pedicle of vertebral arch is spongy bone, there will be loosening after plain screw is fixing, fixing firm not, the postoperative danger occurring displacement and come off.
Utility model content
The purpose of this utility model is to provide a kind of spinous process fixation device, and to solve patient when spinal cord spinal column postoperative vertebral plate spinous process anatomical reduction, spinous process fixes problem firm not.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of spinous process fixation device, this spinous process fixation device is formed by two spinous process fixation device bodies in " 7 " font fastening that is mutually inverted, described spinous process fixation device body is made up of horizontal edge and longitudinal edge, a top of described horizontal edge is provided with adjustment hole, another top is provided with fixing hole, and described longitudinal edge is provided with at least 2 fixing holes.
As further improvement of the utility model, described adjustment hole is rectangular opening.
Further improve as of the present utility model, described fixing hole is counter sink.
This utility model is made up of titanium alloy material, can according to the feature design production plurality of specifications model of cervical vertebra, thoracic vertebra and lumbar vertebra.
This utility model in use, spinous process under occlusion is placed into patient's pedicle of vertebral arch place, with the horizontal edge of spinous process fixation device body, it is first located, the fixing elasticity of spinous process is regulated by adjustment hole, install screw, the longitudinal edge of spinous process fixation device body is separately fixed at the both sides of vertebra, the spinous process under occlusion is just fixed on vertebra safely and reliably again.
The beneficial effects of the utility model are:
(1) this utility model is positioned the spinous process after occlusion by the horizontal edge of spinous process fixation device body, fixing again by longitudinal edge, thus enable spinous process firm be fixed on vertebra, postoperatively not easily to be shifted, the phenomenon such as come off, reliability is high, effectively alleviates the misery of spinal cord spinal column sufferer;
(2) this utility model realizes the fixing elasticity of spinous process by adjustment hole, improves the scope of application of the present utility model;
(3) this utility model is made up of titanium alloy material, and the horizontal edge of spinous process fixation device body can fit like a glove with the shape of spinous process and vertebra, enhances the reliability of product;
(4) this utility model structure is simple, easy to operate, can reuse, and reduces the financial burden of patient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of spinous process fixation device body in Fig. 1;
In figure: 1, spinous process fixation device body, 2, adjustment hole, 3, fixing hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of spinous process fixation device as shown in Figure 1 and Figure 2, this spinous process fixation device is formed by two spinous process fixation device bodies 1 in " 7 " font fastening that is mutually inverted, spinous process fixation device body 1 is made up of horizontal edge and longitudinal edge, a top of horizontal edge is provided with the adjustment hole 2 of rectangle, another top is provided with fixing hole 3, longitudinal edge is provided with at least 2 fixing holes 3, and fixing hole 3 is counter sink.
This utility model in use, spinous process under occlusion is placed into patient's pedicle of vertebral arch place, with the horizontal edge of spinous process fixation device body 1, it is first located, the fixing elasticity of spinous process is regulated by adjustment hole 2, install screw, the longitudinal edge of spinous process fixation device body 1 is separately fixed at the both sides of vertebra, the spinous process under occlusion is just fixed on vertebra safely and reliably again.
By use of the present utility model, after spinal cord spinal operation, vertebral plate spinous process can be fixed on pedicle of vertebral arch by doctor securely, reaches the object of anatomical reduction, alleviates patients' neural's root pain, effectively can prevent the generation of vertebral deformation deformity.This utility model structure is simple, easy to operate, reliability is high, can reuse, and reduces the financial burden of patient.
