Problems solved by technology

[0003] At present, the general treatment methods for the above problems, in addition to implanting pedicle screws to open the intervertebral space, or implanting artificial intervertebral disc fillers (cage, or spacer) to fill the intervertebral space to raise the intervertebral space In addition to opening the neural foramen gap, there is no artificial spinal implant that is simple to operate, easy to install, and safe and effective to solve this problem.

Embodiment Construction

[0045] In order to further illustrate the present invention, the implementation mode is described as follows with preferred specific examples in conjunction with the drawings:

[0046] figure 1 Among them, a spinous process distraction device 10 of the present invention has a left distractor 20 and a right distractor 30 . The left expansion part 20 is a long expansion part, one end is an open end 21, and the other end is a connecting end 22. The open end 21 is in a U-shape, and the opening can be used to directly contact and accept the sleeve. It fits on a spinous process of the spine, and the connecting end 22 is relatively far away from the opening connecting end 21, and another opening connecting end 23 extends, and the connecting end 22 is correspondingly installed and combined with the connecting end 32 of the right expansion member 30 .

[0047] The right stretching part 30 is an I-shaped long stretching part, one end is an open end 31, and the other end is a connectin...

Abstract

The invention relates to a spine acantha strutting device, expecially a spine acantha strutting device, applied between the adjacent spine acantha, which pulls off the adjacent spine acantha using a plurality of revolving connected strutting pieces to relatively revolve to augment the inclination. A spine acantha strutting device is characterized by having a plurality of strutting pieces, whereinthe strutting pieces includes an opening joint end and a connecting end, and the strutting pieces face to face pairwise to make the connecting end to form an included angle in a movable connection. Each opening is contacted with a spine acantha and relatively resolves to level off to a straight line, to enlarge the vertebra clearance of the spine.

Description

technical field [0001] The present invention relates to a spinal process (spinous process) stretching device, in particular to a stretching device applied between adjacent spinous processes, connected with a plurality of rotatable stretching parts, the relative rotation increases Spinous process distraction device with an included angle so as to stretch the adjacent vertebrae apart. Background technique [0002] In traditional spinal diseases, except for injuries caused by traumatic fractures, a considerable proportion of the rest is caused by lesions and atrophy of intervertebral discs, which makes the intervertebral space of the spine narrow, and the nerve foramina (intervertebral foramen) between the intervertebral joints is also relatively large. Shrinkage, and compression to the spinal nerve root, resulting in numbness or pain. [0003] At present, the general treatment methods for the above problems, in addition to implanting pedicle screws to open the intervertebral ...
