Background technology
As everyone knows, in posterior lower lumbar vertebral surgery, pedicle screw-excellent fixed system is the most conventional, but exists operation to appear the shortcoming such as risk, operating time length of complexity, nerve root and dural sac damage.Internal fixation of spine is to grow up on basis fixing in spinous process, the Berthold Hadra of Texas, USA Galveston in 1891 uses steel wire winding on adjacent spinous process, to treat a routine fracture of cervical vertebra patient, has started the beginning of internal fixation of spine.But spinous process is part weaker in anatomy of spine structure, fix through spinous process merely at a lot of positions of spinal column, because of the lower stability requirement that cannot meet biomechanics of constant intensity.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of easy to operate, and good stability, safe and reliable, to the dual fixture of the little spinous process and lamina of body wound.
The method that the present invention solves the employing of surgical technic problem is:
The dual fixture of a kind of spinous process and lamina, comprise fixed plate A, fixing head B, attachment screw and connecting rod, fixed plate A is connected through connecting rod with fixing head B, one side of fixed plate A is provided with connecting rod, fixing head B is provided with the connecting hole and the connecting screw hole that coordinate with connecting rod, fixing head B is connected with connecting rod through connecting hole, connecting screw hole and attachment screw, on the face of fixed plate A and fixing head B and spinous process laminating, be respectively equipped with protruding locking pin, it is characterized in that fixed plate A and fixing head B lower end are respectively equipped with the empennage of routing up laterally that coordinates spinous process root and vertebral plate.
Empennage of the present invention is respectively equipped with protruding taper pin, and the taper pin of projection becomes 20-90 ° of angle with tail surface, to increase fixed effect.
On empennage of the present invention, be respectively equipped with the nail hole of matching with hold-down screw, nail hole can be counterbore, smooth nail hole or thread lock hole, and nail is provided with hold-down screw in hole, and the front end of hold-down screw is cone tip shape, to increase fixed effect.
The fixed plate A of the present invention face corresponding with human body vertebral plate with fixing head B is the cambered surface matching with human body vertebral plate, to increase Area of bearing, to improve therapeutic effect.
Connecting rod of the present invention and fixed plate A are vertical configuration; Locking pin is vertical configuration with fixed plate A and fixing head B respectively; Fixed plate A, fixing head B and empennage and human spine's spinous process and vertebral plate match, and the angle of empennage and fixed plate A, fixing head B is generally 90-170 °.
When the present invention uses, connecting rod in fixed plate A is inserted between spinous process from a side of spinous process, again fixing head B is installed to connecting rod from the opposite side of spinous process, fixing head B passes through connecting hole, connecting screw hole is connected with connecting rod with attachment screw, fixed plate A, one end with empennage when fixing head B installs is on the vertebral plate of human spine lower end (tail end), fixed plate A and fixing head B are exerted pressure to spinous process direction, make locking pin on fixed plate A and fixing head B penetrate respectively the both sides of spinous process, fixed plate A and fixing head B are fixed on the vertebral plate of human body lower end (tail end) by the taper pin on empennage or hold-down screw, the present invention has rational in infrastructure, easy for installation, safe and reliable, wound to human body is little, can effectively realize between spinous process fixing, the advantages such as therapeutic effect is good.
