Abstract
The present invention relates to technical field of medical instruments, a kind of spinous process fixation device is disclosed.The spinous process fixation device mutually inverts fastening by two spinous process fixation device bodies in " 7 " font and formed, the spinous process fixation device body is made up of horizontal edge and longitudinal edge, one top of the horizontal edge is provided with adjustment hole, another top is provided with fixing hole, and the longitudinal edge is provided with least two fixing hole.When in use, spinous process under being engaged is placed at patient's pedicle of vertebral arch, it is first positioned with the horizontal edge of spinous process fixation device body, the elasticity that spinous process is fixed is regulated by adjustment hole, install screw, the longitudinal edge of spinous process fixation device body is separately fixed to the both sides of vertebra again, the spinous process under occlusion is just safely and reliably fixed on vertebra.Postoperative the phenomenon such as to be not susceptible to shift, come off, reliability is high, effectively alleviates the pain of spinal cord backbone sufferer, simple in construction, easy to operate, reliability of the invention is high, repeats and utilizes, reduces the financial burden of patient.
Description
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of dependable performance, it is fixed conveniently, repeatable utilizes
Spinous process fixation device.
Background technology
When patient does intraspinal tumor excision, doctor is direct excision spinous process and vertebral plate to expose tumour, cuts off swollen
Only suture spinal meninges after knurl, backbone do not fix, and does not also receive spinous process and vertebral plate also.Found by Long-term clinical observation for long segment
（More than 3）Campylorrhachia, spinal cord rear portion and muscle adhesion, nerve root occurs the later stage in the patient that spinous process and vertebral plate are removed
The complication such as pain.With continuing to develop for medical technology, international academic community starts to inquire into the problem of spinal cord backbone is postoperative fixed,
Be concentrated mainly on spine nail rod fix+spinal fusion on, achieve good effect really in long segment spinal operation.But
It is, because the high expense of fixed material causes popularization to be subject to certain restrictions and query, especially to intraspinal tumor in 3 sections
Operation within section, the fixation of vertebral plate spinous process seems not essential, but patient's postoperative nerve root pain is that can not avoid asking
Topic.Some neurosurgeries expert attempts that the vertebral plate spinous process completely removed is fixed on into pedicle of vertebral arch using connection sheet, reaches that dissection is multiple
The purpose of position, it is observed that having obvious effect for alleviating nerve root pain, and can prevent vertebral deformation to a certain extent
The generation of deformity.Hospitals at Present does not fix the equipment special of vertebral plate spinous process, and so fixing spinous process with connection sheet after surgery shows
Obtain very trouble laborious, and spinous process pedicle of vertebral arch is cancellous bone, and loosening occurs in plain screw after fixing, fixed not firm enough,
The postoperative danger for occurring displacement and coming off.
The content of the invention
It is an object of the invention to provide a kind of spinous process fixation device, to solve patient in the postoperative vertebral plate spinous process solution of spinal cord backbone
When cuing open reset, the problem of spinous process fixes not firm enough.
In order to solve the above technical problems, the technical solution used in the present invention is：
A kind of spinous process fixation device, the spinous process fixation device is mutual in the spinous process fixation device body of " 7 " font by two
Invert fastening to form, the spinous process fixation device body is made up of horizontal edge and longitudinal edge, a top of the horizontal edge is provided with regulation
Hole, another top is provided with fixing hole, and the longitudinal edge is provided with least two fixing hole.
As a further improvement on the present invention, the adjustment hole is rectangular opening.
As the further improvement of the present invention, the fixing hole is counter sink.
The present invention is made up of titanium alloy material, and production plurality of specifications type can be designed according to the characteristics of cervical vertebra, thoracic vertebrae and lumbar vertebrae
Number.
In the use of the present invention, the spinous process under being engaged is placed at patient's pedicle of vertebral arch, with spinous process fixation device body
Horizontal edge first positions it, regulates the elasticity that spinous process is fixed by adjustment hole, installs screw, then by spinous process fixation device sheet
The longitudinal edge of body is separately fixed at the both sides of vertebra, and the spinous process under occlusion is just safely and reliably fixed on vertebra.
Beneficial effects of the present invention are：
（1）The present invention is positioned by the horizontal edge of spinous process fixation device body to the spinous process after occlusion, then passes through longitudinal edge
Fixed, postoperative the phenomenon such as to be not susceptible to shift, come off so that what spinous process can be firm is fixed on vertebra, reliability is high, has
Alleviate to effect the pain of spinal cord backbone sufferer；
（2）The present invention realizes the elasticity that spinous process is fixed by adjustment hole, improves the scope of application of the present invention；
（3）The present invention is made up of titanium alloy material, the shape that the horizontal edge of spinous process fixation device body can be with spinous process and vertebra
Shape fits like a glove, and enhances the reliability of product.
（4）The present invention is simple in construction, easy to operate, repeats and utilizes, reduces the financial burden of patient.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of spinous process fixation device body in Fig. 1；
In figure：1st, spinous process fixation device body, 2, adjustment hole, 3, fixing hole.
Embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
A kind of spinous process fixation device as shown in Figure 1 and Figure 2, the spinous process fixation device is consolidated by two spinous process in " 7 " font
Determine device body 1 and mutually invert fastening to form, spinous process fixation device body 1 is made up of horizontal edge and longitudinal edge, a top of horizontal edge
Adjustment hole 2 provided with rectangle, another top is provided with fixing hole 3, and longitudinal edge is provided with least two fixing hole 3, and fixing hole 3 is heavy
Head bore.
In the use of the present invention, the spinous process under being engaged is placed at patient's pedicle of vertebral arch, with spinous process fixation device body 1
Horizontal edge first positions it, regulates the elasticity that spinous process is fixed by adjustment hole 2, installs screw, then by spinous process fixation device
The longitudinal edge of body 1 is separately fixed at the both sides of vertebra, and the spinous process under occlusion is just safely and reliably fixed on vertebra.
By the use of the present invention, after spinal cord spinal operation, vertebral plate spinous process can be stably attached to pedicle of vertebral arch by doctor,
The purpose of anatomical reduction is reached, patients' neural's root pain is alleviated, can effectively prevent the generation of vertebral deformation deformity.Present invention knot
Structure is simple and convenient to operate, reliability high, is repeated and is utilized, reduces the financial burden of patient.
