Embodiment Construction

[0022] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0023] A sublaminar distraction mobilizer of the present invention includes a lamina distraction part 100 and a spinous process support part 200, the spinous process support part 200 and the lamina distractor 100 are fixed to each other or have an integral structure, The lamina distraction part 100 includes a fixing part 102 and two lower lamina hooks 101 arranged opposite to each other. sides.

[0024] The two lamina hooks 101 extend from between the lamina 2 of the upper and lower vertebrae into the space between the lamina 2 of the two vertebrae, and are respectively hooked under the two lamina 2 of the upper and lower vertebrae. The lower lamina hook 101...

Abstract

The invention discloses vertebral plate lower portion strutting movement apparatus. Two vertebral plate bottom hooks of a vertebral plate strutting part can hook vertebral plates of two joints of the spine on the inner side; the supporting point is close to the vertebral plate lower portion, and the apparatus is close to a facet joint; thus, the vertebral plate lower portion strutting movement apparatus is close to the physical activity axis of the spine, and the spine is closer to the activity range of the normal spine. The vertebral plate strutting part can strut the vertebral plates of the two joints of the spine to reduce pressure of the intervertebral disc and the facet joint, and therefore the protrusion, stenosis and degeneration of the intervertebral disc are treated, and the physiological curvature of the spine is recovered. A spinous process supporting part is provided with a gap and can abut against the spinous process of the two joints of the spine, a hypsokinesis movement space between the two spinous processes can be kept, and the strutting and movement action of the vertebral plate strutting part is guaranteed. By means of the vertebral plate lower portion strutting movement apparatus, major surgery is avoided, by supporting the vertical plates height, the compression pain of the nerve root can be relieved, the pressure of the intervertebral disc and the facet joint can be reduced, and instability and malformation caused by the protrusion, stenosis and degeneration of the intervertebral disc are treated.

Description

technical field [0001] The invention relates to a distraction movable device under the lamina. Background technique [0002] Currently, there is no better way to relieve degenerative diseases of the spine in the early stage, and often the only option is to fix the spine with a nail plate at the end to relieve the pain. After spinal fixation and fusion surgery, many years of follow-up, there are many problems of early degeneration of adjacent segments. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiency that the existing treatment of spinal degenerative diseases cannot alleviate spinal degeneration very well, the present invention provides a sublaminar distraction actuator. [0004] The technical solution adopted by the present invention to solve the technical problem is: a sublaminar distraction device, comprising a lamina distraction part and a spinous process support part, and the spinous...
