Description
Technical field
The present invention relates to a kind of vertebral body fixture, especially relate generally to one and have stage supporting, effectively force is implanted in dispersion, and tool function of regulating height thereof, provides implant surgery to have more vertebral body fixture that is laborsaving, fast accurate not slippage.
Background technology
The vertebra of human body is easily because age, accident, motion, long-term posture are bad or the external force factor such as employment injuries, vertebra is made to occur dislocation, cartilage degradation and hyperosteogeny, especially old degenerative spine disease becomes, severe patient very can cause the complications such as other dysfunction of organ of health to occur, and be that solution vertebra degeneration pathological changes with age or other external force cause uncomfortable problem, common to implement interbody fusion or to solve in the mode of intervertebral implantable artificial intervertebral disc.
Announce the spinal implants such as M414944, M411920, M409825, M400307 and No. M384014 as TaiWan, China, be and replace the original intervertebral disc of human body, implant between adjacent two vertebras (or lumbar vertebra), to provide support and to cushion function.So because the spacing between its adjacent vertebral bodies of different people differs, and the implant such as above-mentioned is because being all fixed single dimensional structure, to have too tightly on implant surgery is suitable for or too loose phenomenon occurs, be also, that can produce or too late problem does not still attain perfect with above-mentioned utility model.
Another person, if No. US5554191, U.S. Publication is that a kind of bone merges vertebra cage implant, learnt by its drawing, mainly having surface at a supporting body 3 is provided with serrated face 312, two support portions 31 of 313, 32, this two support portion 31, 32 are arranged with the oblique guide face 310 forming V shape opening 342 in open end, 320, one bolt 36 wears supporting body 3, two support portions 31 are protruded in one end, a part 37 is compeled in conjunction with one in 32 open ends, this is made to compel under part 37 normality to terminating in two oblique guide faces 310, 320, when implanting that between two vertebral bodys, this bolt 36 is by rotating tool 4 turn, two support portions 31 can be supported, the suitable angle of 32 formation extends out the effect between support two vertebra.
But, though this structure can rely on tool angular expanse structure to solve different spacing dimensional problem between everyone two vertebral bodys, so this structure is in implant surgery operation, must first by two support portions 31, 32 support first be engaged two vertebral bodys fixing after, continue turn again and support action, right in this two support portion 31, 32 is all single chip architecture, cause implant surgery to operate and must impose larger force, just be able to two support portions 31, 32 first strut occlusion two vertebral body, also i.e. operation force is comparatively required great effort, to cause in implant surgery process easily because the excessive easy slip that exerts a force cannot accurate contraposition risk, must remake and readjust, increase operation degree of difficulty, delay the problem such as operating time and patient burden, and can wait to be improved.
Therefore, how to solve the problem be the present invention primary problem for solving, therefore inventor be through constantly think hard with study after, finally obtain certainly effect, and initiate out the present invention.
