The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1～4, thoracic and lumbar vertebral posterior prosthesis comprises artificial spinous process 1, artificial neural plate 2, and described artificial spinous process 1 is connected with artificial neural plate 2, and this connection is the spinous process of human body cone and the shape that is connected of vertebral plate.
Also comprise artificial interspinal ligaments, described prosthese is connected and fixed by the spinous process and the vertebral plate of artificial interspinal ligaments with artificial spinous process 1 and artificial neural plate 2 and adjacent segment human body; Described artificial spinous process 1 is the rectangular-shaped of hollow, comprise the upper end open 3, the lower ending opening 4 that are used to embed upper and lower sections spinous process, the rear opening 5 that is used for bone grafting, and the ligament fixed structure 6 that is used for fixing artificial interspinal ligaments, the edge, front and back of described upper end open 3, lower ending opening 4 all is the arc of indent, and described ligament fixed structure 6 is located at the both sides of artificial spinous process 1; Described artificial neural plate 2 is shape two thin plates identical and that be connected with artificial spinous process 1 one, the preceding respectively oblique front portion that is symmetricly set in artificial spinous process 1 both sides of these two thin plates, and be 40 °～45 with artificial spinous process 1, both sides are the arc of indent about it, are butterfly-shaped; Be equipped with the conduction hole 7 of drain after being convenient to perform the operation on two above-mentioned thin plates; Described ligament fixed structure 6 is a pair of projection, and this a pair of projection is provided with the both sides with artificial spinous process respectively, and is equipped with the duct 8 of above-below direction; Described artificial interspinal ligaments passes from the duct 8 of artificial spinous process both sides and is connected with the ligament tissue of adjacent segment cone; Described artificial spinous process 1, artificial neural plate 2 all adopt acellular artificial bio-membrane material; Described acellular artificial bio-membrane material comprises the PEEK material; Described artificial interspinal ligaments adopts the adsorbable artificial ligaments biomaterial; Described adsorbable artificial ligaments biomaterial is for absorbing the complex of gutstring and zonal pig intestinal mucosa lower floor.
At breast straitness of lumbar vertebrae patient, after the conventional full vertebral plate decompression of tradition, rebuild with the breast lumbar vertebra posterior column structure that the artificial rear pillar complex of breast lumbar vertebra prosthese excises, recover its physiological structure and physiological function.Can possess the function that merges with non-converged fixed simultaneously, carry out as required in the art freely selecting.
Prosthese is made up of artificial spinous process, artificial interspinal ligaments, artificial neural plate three part-structures, artificial spinous process, artificial interspinal ligaments PEEK material.
Artificial spinous process is integrated with artificial neural plate, and artificial spinous process is the cuboid of a hollow, and its upper and lower side and rear are open opening, and upper and lower end is an arc, is connected with the spinous process of sections up and down respectively, and the rear opening is convenient to bone grafting usefulness.As select non-converged fixed function, need not bone grafting in the artificial spinous process; Go into as selecting the converged fixed function, need bone grafting in the artificial spinous process of hollow, carry out the bone fusion by the upper and lower port of artificial spinous process and the spinous process of neighbouring sections.
Artificial neural plate is the thin PEEK plate of material of butterfly diagonal; cross over the spinal canal decompression scope; carry out bridge joint with neighbouring vertebral plate trailing flank; can carry out cutting according to actual size required in the art; when vertebral canal volume enlarged after keeping spinal canal decompression, protection decompression back canalis spinalis content was avoided the compressing of cicatrix, plant bone mass on every side and is caused decompression failure or external force to spinoneural damage in the canalis spinalis.Evenly boring is beneficial to postoperative drain on the artificial neural plate, avoids postoperative generation intraspinal hematoma and hematoma secondary infection to spinoneural damage.As select non-converged fixed function, need not bone grafting; As select the converged fixed function, and can on artificial neural plate, carry out bridge joint, also avoided the bone grafting displacement to enter Spinal Cord nerve in the canalis spinalis simultaneously.
Artificial interspinal ligaments adopts the adsorbable artificial ligaments biomaterial, can be substituted by the human body ligament tissue, avoids the defective of the easy fatigue fracture of non-absorption artificial ligament, thereby makes it become permanent implant.Be connected to a fixed by the spinous process and the vertebral plate of artificial ligament artificial spinous process and vertebral plate complex and adjacent segment.
