Description
Technical field
The present invention relates to a kind of vertebral body fixture, especially relate generally to one and there is stage supporting, effectively disperse to implant the application of force, and tool function of regulating height thereof, provide implant surgery to have more vertebral body fixture laborsaving, not slippage of fast accurate.
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, make vertebra occur dislocation, cartilage degradation and hyperosteogeny, especially old degenerative vertebral disease, severe patient very can cause the complications such as other dysfunction of organ of health to occur, and be to solve degenerate with age pathological changes or other external force of vertebra to 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, so that on implant surgery is suitable for, have too tightly or too loose phenomenon occurs, be also, problem that can produce or too late is still not attain perfect with above-mentioned utility model.
Another person, if U.S.'s bulletin is for No. US5554191 that a kind of bone merges vertebra cage implant, learnt by its drawing, mainly there is surface at a supporting body 3 and be provided with serrated face 312, 313 two support portions 31, 32, this two support portion 31, 32 are arranged with the oblique guide face 310 that forms 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, make this compel to support and terminate in two oblique guide faces 310 under part 37 normality, 320, implant between two vertebral bodys when this bolt 36 is by rotating tool 4 turn, can support two support portions 31, 32 form suitable angle extends out the effect supporting between two vertebras.
But, though this structure can rely on tool angle expansion structure to solve different spacing dimensional problem between everyone two vertebral bodys, so this structure is in implant surgery operation, must be first by two support portions 31, 32 support first interlock two vertebral bodys fixing after, continue again turn and support action, so because of this two support portion 31, 32 is all single chip architecture, cause in implant surgery operation and must impose the larger application of force, just be able to two support portions 31, 32 first strut interlock two vertebral bodys, also operate in the application of force and require great effort, cause in implant surgery process easily because of the excessive easy slip of the application of 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 address the above problem and be the primary problem that institute of the present invention wish solves, therefore this case inventor be through constantly think hard with study after, finally obtain sure effect, and initiate out the present invention.
