Description
Technical field
The invention provides a kind of in and the fixture of actions between two vertebral bodies, especially refer to be applied in two adjacent thoracic vertebra, lumbar vertebras ... between vertebral body Deng vertebra, so that can keep stable between two adjacent vertebral bodys, not adjacent interpyramidal activity of reason two-phase such as antecurvature, layback, about incline and about reverse, and problems such as two vertebral fusion are bad take place.
Background technology
Press, general alleged " waist interbody fusion (interbody fusion) ", it mainly is to carry out from the way of escape (with the strip off of lumbar vertebra neurocele dura mater) or the past road (the vertebra dish the place ahead from the preabdomen to the pneumoretroperitoneum), earlier the intervertebral disc of degenerating is removed, make between adjacent two lumbar vertebra bodies till the no remaining soft tissue, again human body bone (from body or allosome) is implanted between adjacent two lumbar vertebra bodies, after the several months merges, make two lumbar vertebra bodies respectively with the lumbar vertebra body of human body bone formation one monoblock, so as to reaching elimination because of lumbar intervertebral disc is degenerated and pathological changes caused lower back pain problem.
In order to promote the fusion rate between lumbar vertebra body and human body bone, medical circle is to develop the instrument of " pedicle nail system (pedical screwsystem) " and " metal cage (cage) ", wherein said pedicle nail uses in operation on vertebra, be fused to example with the way of escape, see also Figure 1 and Figure 2, it is lower back portion muscle strip off with the patient, transverse process 11 up to both sides, a vertebra 10 rear exposes, after running through a metallic rod 21 with screw 20 again, squeeze in the pedicle of vertebral arch 12 of described vertebra 10, with two adjacent vertebral bodys 101,102 is example, for making described two adjacent vertebral bodys 101,102 can be maintained fixed the gap, be total to four screws 20 of palpus and two metallic rod 21, wherein each metallic rod 21 needs two screws 20, on it and lower end is fixed to respectively and hypocentrum 101, in 102 the corresponding pedicle of vertebral arch 12, so that described two adjacent vertebral bodys 101,102 unlikely activities, again the human body bone is implanted between two adjacent lumbar vertebra bodies 101 afterwards, 102 the intervertebral disc space of having removed, so, this two lumbar vertebras body 101,102 respectively with the human body bone through several months bone growth, can form a monoblock lumbar vertebra body, realize eliminating the lumbago problem that lumbar intervertebral disc is degenerated and pathological changes caused.
Yet use " pedicle nail system " to carry out operation on vertebra, though can keep the fixing of 101,102 of two adjacent vertebral bodys, at first, because the active force that bears on each rear metallic rod 21, be two the place ahead screws 20 that see through its upper and lower side, conduct to the intersection of screw 20 and metallic rod 21, cause screw 20 easily with the intersection of metallic rod 21, the problem of fracture takes place; Secondly, for osteoporotic patient, the problem that screw 20 gets loose takes place easily also, place another big problem of pedicle nail system simultaneously from the back, be very easily the little joint of dorsal muscles and vertebra back of the body side to be damaged, cause meat fiberization, cause the operation back to continue the problem of back pain.If screw 20 when squeezing into the position partially in, still can cause nerve root injury.
In view of this a problem, medical circle is to develop " metal cage " to use in operation on vertebra, see also shown in Figure 3, described metal cage 31 is a kind of cellular and the hollow column that is hollow out, materials such as material by titanium or compatible human body are made, modus operandi is the mode that the road or the way of escape before the metal cage 31 are merged, be placed on two adjacent vertebral bodys 301,302, bear and suppress two adjacent vertebral bodys 301 with metal cage 31,302 pressure and interaction, make two adjacent vertebral bodys 301,302 can remain a fixed interval (FI), make the human body bones of filling in the metal cage 31 can pass through hole 310 on the metal cage 31, respectively with two adjacent vertebral bodys 301,302 touch mutually, and stable growth, and then with last hypocentrum 301, the final purpose that merges between vertebral body is reached in 302 combinations.
Research report shows that the practice of using pedicle nail is to have increased the joint generation degeneration of adjacent vertebral and the probability of pathological changes, in operation and after the operation, will cause following negative effect to the human physiological structure simultaneously:
1. see also Figure 1 and Figure 2, insert the practice of pedicle nail, because of need go deep into vertebra 10 rears in way of escape mode, very easily dorsal muscles and little joint are damaged, cause the patient after operation, the back still pain endlessly, this also be patient back, operation back constant pain main cause one.
2. see also Figure 1 and Figure 2, screw 20 is squeezed into pedicle of vertebral arch 12, very easily in operation, injure the nervous tissue of pedicle of vertebral arch 12 inboards,, cause the patient to undergo surgery once more with degeneration that causes adjacent discs and pathological changes in the future.
3. see also Figure 1 and Figure 2, because metallic rod 21 must be born vertebral body 101 fully, 102 six directions are (antecurvature, layback, about incline and about reverse) active force and torsion, and described active force and the torsion of waiting is two screws 20 that see through its upper and lower side, conduct to the fixing point that is driven into screw 20 on the pedicle of vertebral arch 12, very easily make vertebral body 101, porotic bone is because of bearing huge unit active force and torsion repeatedly in 102, and cause vertebral body 101, porotic bone softer in 102 bursts apart, thereby causes screw 20 from vertebral body 101, get loose in 102 the porotic bone.
4. see also Figure 1 and Figure 2, the active force of six direction and torsion on the metallic rod 21, be that minimum section via screw 20 bears, so very easily because of secular stress concentration, cause metal tired, and then make screw 20 in the position, boundary of metallic rod 21 with vertebral body 101,102, rupture.
In addition, see also shown in Figure 3, road or way of escape mode were used the practice of metal cage separately in the past, though there are not the deutero-problems of pedicle nail, but because metal cage 31 is merely to be placed on 301,302 of two adjacent vertebral bodys, so according to biomechanics Research, the pedicle nail system can effectively control the activity of the six direction of 301,302 of two adjacent vertebral bodys really, independent metal cage 31 then only can be controlled left and right activity of inclining, for the active control of other four direction (antecurvature, layback and about reverse) all than the pedicle nail system for poor.
Therefore, need develop a new technique and avoid aforementioned every shortcoming, effectively control the activity of six direction between vertebral body, and human body is caused minimum destruction, promptly become now medical circle and still make great efforts to research and develop and desire most ardently an important goal of reaching.
