This utility model realizes its function mainly following step: one is set up service aisle, and two is that equipped implanting portion 1 enters access sheath 2, and three is lay implanting portion 1 to arrive cone process section, and four is release implanting portion 1, and five is enhancing perfusion and pathway closure art.
One, service aisle is set up
Nut location is bored vertebral body according to location probe 4, and determine angle and carry out labelling, then drill bushing is guided to place, lower drill bit after extracting location probe 4, it is drilled into collapse of vertebra portion, inserting, with location probe 4, the portion of subsiding again and repair the degree of depth and circumference that expand the hole, portion that subsides, the service aisle that access sheath 2 is set up is inserted in examination subsequently with checking, if can guarantee that implanting portion 1 arrives off-position.
Two, equipped implanting portion enters access sheath
When aseptic ice normal saline, clamping implanting portion 1 with pliers makes it be constraint state, with pushing guide rod 3 traverse access sheath 2, propelling movement handle 3-1 is made to slide in the chute of guide plate 2-3, expose the T font union joint 3-2 pushing guide rod 3 head, again T font union joint 3-2 is inserted in the gap 1-3 of implanting portion 1 afterbody, by implanting portion 1 90-degree rotation, propelling movement guide rod 3 is made to form hinge joint with implanting portion 1, then pull and push guide rod 3 and make implanting portion 1 enter in the tube chamber of access sheath 2 and concordant with the mouth of pipe, now, the holding handle 2-2 pushing handle 3-1 and access sheath 2 is 90 degree, to show assembling state.
Three, lay implanting portion and arrive cone process section
Being inserted in the access opening that has built up and to bottom by the assembly assembled, its degree of depth is consistent with former insertion depth, and adjustment angle makes the V-type expanding unit of implanting portion 1 and collapse of vertebra direction in the same direction.
Four, release implanting portion
The propelling movement handle 3-1 pushing guide rod 3 that holds with a firm grip is motionless, and the chute along guide plate 2-3 is slowly extracted access sheath 2 to implanting portion 1 and departed from the constraint of access sheath 2, is in release conditions. Restriction because of guide plate 2-3, make propelling movement handle 3-1 be adjacent to holding handle 2-2 and relative angle is motionless, turned-out after about 2 minutes convince by patient analysis to plate 2-3, fine motion pushes handle 3-1, sensation implanting portion 1 whether movable (operation can be observed under the guiding of C type X-ray machine by hospital with good conditionsi), with determine implanting portion 1 discharge whether reach expection, then guide rod 3～5 millimeters is inwardly pushed again, handle 3-1 90-degree rotation will be pushed, making T font union joint 3-2 extract gently after deviating from hinge joint state and being in a parallel surface with gap 1-3, namely release accused.
Five, enhancing perfusion and pathway closure art
After implanting portion 1 release produces a desired effect, clinic needs to implant the broken bone of spongiosa or with in bone cement perfusion to access sheath 2, consolidating bar 5 pressure injection bone cement to the gap strutting vertebral body with bone cement, repeatedly pressure injection is to guarantee that filling bone cement fills whole vertebral body space; Finally extract access sheath 2, close drilled tunnel with bone cement. Bore nut at the symmetrical side of vertebral body of subsiding again according to said process to be carried out, after terminating, sew up wound surface successively.
The size visual vertebral body position of implanting portion 1 is different from pedicle channel place width, can have different specifications to adapt to the use of each section of collapse of vertebra case;Implanting portion 1 big I of the produced power of shoring when shoring state, by the diameter control of silk material, can adopt dual-gripper or cross support to meet the vertebral body requirement to the power of shoring of subsiding.
Implanting portion 1 of the present utility model is made up of NiTi marmem, there is shape memory function, in Low-temperature Ice normal saline, metallographic structure enters martensitic state, the constraint state of pole shape can be shaped as by external force, under the impact of ambient temperature, shape energy Quick-return is to original-shape, when implanting portion 1 is in intermediateness, when namely shoring state, produce recovery of shape power thus reaching the effect shored, vertebral body of subsiding can be done work by the power of shoring produced by this phase transformation, so as to lifting recovers to original physiological structure shape; This utility model compact structure, installs simple to operate, shores power persistent pressure produced by after release, and confronts with each other acting with Vertebral Compression power of subsiding, and dynamic restoring subsides the physiological defect of vertebral body, eliminates affected tissue compensatory, improves the toleration of bone.
Particular embodiments described above; this utility model is solved the technical problem that, technical scheme and beneficial effect have further described; it is it should be understood that; the foregoing is only specific embodiment of the utility model; it is not limited to this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
