Clinical usefulness is locked multi-C stereo fixture in the marrow in length and breadth
Technical field
The present invention relates to a kind of clinical usefulness and lock in length and breadth multi-C stereo fixture in the marrow, especially for the internal fixation device equipment for the treatment of long tubular bone fracture or malformation correction treatment.
Background technology
At present, intramedullary nail with lock does not arrange vertical lock and can not fix by multi-C stereo in the prior art, the spongy bone pinning is not set yet, need be long with operating time, the fixing difficulty of first inserting end pinning, wound area is large, need after the operation to take out an end pinning with secondary, otherwise height occurs in the disunion rate, causes the phenomenon of broken nail, increase the patient suffering, brought many inconvenience to operator; The pre-bending position of intramedullary pin is constant in addition, with bone physiology camber larger difference is arranged, the fixing of inapplicable and intercondylar fracture of the femur and fracture of femoral neck and intertrochanteric fracture of the femur.
Summary of the invention
The clinical usefulness of the present invention is locked the purpose of multi-C stereo fixture in the marrow in length and breadth, to overcome defects and a kind of clinical usefulness that designs is locked multi-C stereo fixture in the marrow in length and breadth, it is the stringer chute that adopts the cross locking nail and willfully press spongy bone pinning or neck of femur pinning and marrow inner fixer, vertical pinning slides in the stringer chute and has certain elasticity, cross locking is followed closely and is willfully pressed spongy bone pinning or neck of femur pinning to form multi-C stereo in medullary cavity and fixedly secures, after enter end and fixedly be easy to squeeze into the cross locking nail with sight, that realizes the treatment for the treatment of long tubular bone fracture or malformation correction locks the purpose that multi-C stereo is fixed in the marrow in length and breadth.
The clinical usefulness of the present invention is locked in length and breadth the interior multi-C stereo fixture of marrow and is taked following technical scheme to realize, it is by sight, the spongy bone pinning, the cortical bone pinning, the marrow inner fixer, vertical pinning, neck of femur pinning and support nail consist of, the place, both sides arranges the stringer chute in the marrow inner fixer, the vertical pinning of device in the stringer chute, vertical pinning has certain elasticity, the two ends of marrow inner fixer are respectively head end and tail end, Baltimore groove is set on the head end and supports pinning and vertical pinning, device support lock nail in the Baltimore groove, the lid silk is set on the tail end, the tail end hoop, the tail end leading screw, locking nail hole, U-lag and six rib grooves, penetrate respectively the cortical bone pinning in the locking nail hole, spongy bone pinning and four neck of femur pinnings, be nested with the tail end hoop on the tail end of marrow inner fixer, the lid silk is connected with tail end leading screw screw thread, on the tail end of stringer chute U-lag is set, device sight in the U-lag; With the head end of fixedly clamoring in the marrow after the end pulp cavity of fracturing enters other end pulp cavity, squeezed into from the tail end head-end along the stringer chute of marrow inner fixer by vertical pinning and to be fixed on the cortical bone, the stringer chute mouth of head end tilts can guarantee vertical pinning to both sides, the head end sensing cortical bone of vertical pinning is fixed when going out along the head end outlet of stringer chute; Again with spongy bone pinning or cortical bone pinning through a side seam spongiosa or cortical bone is passed the offside spongy bone or cortical bone is fixed, intertrochanteric fracture of the femur or fracture of femoral neck person lock on the marrow inner fixer setting of neck of femur locking nail hole not in one plane in length and breadth, can three-dimensional locking in neck of femur with the neck of femur pinning; The support pinning of head end will support pinning through sight and walk crosswise and squeeze into the medullary cavity center and can block in the Baltimore groove of head end, to cover silk after being wiped out by the outstanding tail end hoop redundance of vertical pinning and be screwed in the tail end leading screw, what reach the treatment for the treatment of long tubular bone fracture or malformation correction locks the effect that multi-C stereo is fixed in the marrow in length and breadth.
The effect that the clinical usefulness of the present invention is locked multi-C stereo fixture in the marrow in length and breadth is simple in structure, flexible to operation, but closed reduction is installed, shortened operating time, reduce the operation wound area, need not take out an end pinning as second operation, be conducive to patients ' recovery, it is painful to have alleviated patient, is widely used in the training equipment of long tubular bone fracture or malformation correction.
