Abstract
The utility model provides an elastic dynamic intraspinal fixing system. The system comprises an elastic connecting rod, which comprises a convex ball rod and a concave ball rod; wherein, both the top of the ball of the convex ball rod and the bottom of the concave ball socket of the concave ball rod are provided with holes with the same diameter, which can be communicated with each other after spherical connection; an inner core composed of wires is arranged in the holes; the rotation limit of the connected elastic connecting rod is eight degrees; and the elastic connecting rod, pedicle screws and a locker such as a separate ball-connected intraspinal fixing device and U-shaped screws form the elastic dynamic intraspinal fixing system. The utility model has the following effects: the system can effectively realize dynamic stable fixation and is flexible along the bending direction of the normal bending curve of the vertebral column and rigid in the directions of compression, cutting and rotation, consequently, the treatment-related motion mode of the vertebral sections can be changed, and the functions of tissues can be kept or reconstructed.
Description
Technical field
This utility model relates to a kind of Dynamic Elastic spinal internal fixation system, belongs to passing through particularly way of escape treatment spinal lesion of spinal column front and back road in the bone surgery.Orthopedic system is fixing when being applicable to because of spinal column regression, wound and orthomorphia, improves the motor pattern of the related sections of treatment, keeps or rebulid the function of tissue.The fixed characteristics of dynamic stability are that the bending direction at the normal buckling curve of spinal column is flexible, and are inflexible in compression, shearing and rotation direction.
Background technology
Some uses of following closely excellent connected system are when spinal column regression, trauma operation, pitman is fixed on the pedicle nail, all directions stressed is inflexible between the sections, this recovery for function has very big obstruction, especially pain, the inflammation that some pain sources are caused need provide a kind of fully dynamic stabilisation systems to seem powerless.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of Dynamic Elastic spinal internal fixation system, make functional rehabilitation when being beneficial to solve treatment as far as possible, alleviate, treat the pain that some pain sources cause, and can problem such as use mutually with non-resilient pitman.
For achieving the above object, the technical solution adopted in the utility model provides a kind of Dynamic Elastic spinal internal fixation system, this system includes the elasticity pitman, wherein: described elasticity pitman is made up of protruding bat and recessed bat, end at described protruding bat has a protruding ball, end at described recessed bat has a recessed ball groove, forms ball-joint between the two.At the ball top of described protruding bat and the recessed ball trench bottom of recessed bat the identical hole of one diameter is arranged all, become and then be the hole that communicates after ball-joint, the hole is built-in with the inner core of being made up of the tinsel of one group of some, and its crooked limit of the elasticity pitman after the connection is 8 degree; This elasticity pitman and pedicle nail, locking device, as: the split ball connects internal fixation of spine device, U sprig etc. and forms the Dynamic Elastic spinal internal fixation system.
Effect of the present utility model is that this system has realized that effectively dynamic stability fixes, and is flexible at the bending direction of the normal buckling curve of spinal column, and crooked limit is 8 degree, and is inflexible in compression, shearing and rotation direction.
Description of drawings
Fig. 1 is a structural representation front view of the present utility model.
Fig. 2 is a structural representation front view A-A profile of the present utility model
Among the figure:
1, protruding bat 2, recessed bat 3, metal wire inner core 4, pedicle nail 5, locking device
The specific embodiment:
Structure to this utility model Dynamic Elastic spinal internal fixation system is illustrated in conjunction with the accompanying drawings.
As shown in drawings, this utility model Dynamic Elastic spinal internal fixation system, this system includes the elasticity pitman, wherein: described elasticity pitman is made up of protruding bat 1 and recessed bat 2, end at described protruding bat 1 has a protruding ball, end at described recessed bat 2 has a recessed ball groove, forms ball-joint between the two.At the ball top of described protruding bat 1 and the recessed ball trench bottom of recessed bat 2 the identical hole of a diameter is arranged all, becoming becomes the hole that communicates after ball-joint, the hole is built-in with the inner core of being made up of the tinsel of one group of some 3, and its crooked limit of the elasticity pitman after the connection is 8 degree; This elasticity pitman and pedicle nail 4, locking device 5, as: the split ball connects internal fixation of spine device, U sprig etc. and forms the Dynamic Elastic spinal internal fixation system.
This utility model Dynamic Elastic spinal internal fixation system is achieved in that
One end of the protruding bat 1 of Dynamic Elastic spinal internal fixation system has a protruding ball, at an end of described recessed bat 2 a recessed ball groove is arranged, and forms ball-joint between the two.The recessed ball trench bottom of the ball top of protruding bat 1 and recessed bat 2 all has the identical hole of a diameter, becoming becomes the hole that communicates after ball-joint, the hole is built-in with the inner core of being made up of the tinsel of one group of some 3, any end of the elasticity pitman after the connection applies certain power all can be along the rotation of ball connecting portion center, and its rotation (bending) is 8 degree to the maximum.The elasticity pitman can return to original state (straight line) after removing external force; So just realized that the elasticity pitman is flexible on the bending direction of the normal buckling curve of spinal column, and in compression, shear direction is inflexible, the elasticity pitman can return to original state (straight line) after removing external force, and this point is to realize one of fixed effective design of dynamic stability.The staight shank end of the protruding bat 1 of this elasticity pitman and the staight shank end of recessed bat 2 and pedicle nail 4, locking device 5, as: the split ball connects internal fixation of spine device, U sprig etc. and forms the Dynamic Elastic spinal internal fixation system, realized that effectively dynamic stability fixes, and then can change the motor pattern for the treatment of related vertebral body sections, keep or rebulid the function of tissue.
