Abstract
The utility model discloses a sacroiliac joint internal fixator which comprises a magnum vertebral arch pedicle pulling nail and a reconstruction steel plate. At least two fixing holes are formed on the reconstruction plate, the magnum vertebral arch pedicle pulling nail is inserted in one of the fixing holes, and a pressurizing horizontal connecting rod is inserted in the other fixing hole; a screw bolt is screwed with a remote reconstruction steel plate end of the pressurizing horizontal connecting rod. During the operation, the iliumes on both sides are reliably fixed by the pressurizing horizontal connecting rod and the reconstruction steel plate, so that the biomechanics determination basically reaches the normal level, the perpendicular shearing force resistance is improved, the in-bed treating time is reduced, the rehabilitation ability is improved. Since the pressurizing horizontal connecting rod serves the stabilization function, the hazards, such as the loosing and displacement of the fixation positions, can be reduced, and the firmness and the stability of internal fixator can be improved even when a patient moves by accident. The internal fixator of the utility model has the advantages of good perpendicular shearing force resistance, minimal invasiveness, and high firmness and stability of fixation positions.

Summary of the invention
It is better that technical problem to be solved in the utility model provides a kind of anti-vertical shear, Wicresoft, the firmness of fixed bit and the higher sacroiliac joint inner fixer of stability.
This utility model solves the problems of the technologies described above the technical scheme that is adopted: comprise sacrum pedicle of vertebral arch pulling force nail and reconstruction plate, described reconstruction plate is provided with at least two fixing holes, be plugged with described sacrum pedicle of vertebral arch pulling force nail in the described fixing hole of one of them, other have be plugged with in the described fixing hole pressurization horizontal connecting rod, the reconstruction plate end far away of the horizontal connecting rod of described pressurization is bolted with bolt.
Described reconstruction plate is provided with three fixing holes, comprises left fixing hole, right fixing hole and center fixed hole, and described sacrum pedicle of vertebral arch pulling force nail is plugged in the described right fixing hole, and the horizontal connecting rod of described pressurization is plugged in described left fixing hole or the center fixed hole.
Described sacrum pedicle of vertebral arch pulling force nail is the sacrum pedicle of vertebral arch pulling force nail of coaxial hollow.
The horizontal connecting rod of described pressurization is the horizontal connecting rod of pressurization of coaxial hollow.
Sacrum pedicle of vertebral arch pulling force nail of the present utility model also can substitute with sacrum pedicle of vertebral arch nail.
Be arranged with auxiliary reconstruction plate on the horizontal connecting rod of described pressurization before described bolt, described auxiliary reconstruction plate is provided with at least two auxiliary fixing holes, is plugged with auxiliary sacrum pedicle of vertebral arch pulling force nail in the described auxiliary fixing hole of one of them
Compared with prior art, advantage of the present utility model is: the sacroiliac joint inner fixer comprises sacrum pedicle of vertebral arch pulling force nail and reconstruction plate, reconstruction plate is provided with as for two fixing holes, be plugged with sacral nut pulling force nail in the fixing hole of one of them, other have be plugged with in the fixing hole pressurization horizontal connecting rod, the reconstruction plate end far away of the horizontal connecting rod that pressurizes is bolted with bolt; Insert sacrum pedicle of vertebral arch pulling force nail in sacrum 1 pedicle of vertebral arch when performing the operation like this, sour jujube is inserted the horizontal connecting rod of pressurization and uses bolting behind the bilateral ilium, add press fit at a side ilium plate rear side by the reconstruction plate connection, by horizontal connecting rod and reconstruction plate the fixing of pressurizeing to the both sides ilium, fixing reliable, biological mechanics determining reaches normal level substantially, improved anti-vertical shear, reduced the bed service time, promoted rehabilitation ability, moved when careless, because the Stabilization of the horizontal connecting rod of pressurization people, reduce the risk that fixed bit becomes flexible or misplaces, improved the firmness and the stability of inner fixer.Also reduced fixed bit when performing the operation with this utility model, otch respectively is that wound surface is little about 2cm, has improved operative speed, has saved operating time.Therefore this utility model is that a kind of anti-vertical shear is better, Wicresoft, the firmness of fixed bit and the higher sacroiliac joint inner fixer of stability.Reconstruction plate is provided with three fixing holes, is according to surgical injury degree needs, and the horizontal connecting rod that pressurizes can be selected to be plugged in sacrum pedicle of vertebral arch pulling force nail fixing hole nearer or far away.The sacrum pedicle of vertebral arch pulling force nail of coaxial hollow and the horizontal connecting rod that pressurizes are inserted conveniently along guide pin, have improved operative speed, and damage is also reduced.Be arranged with auxiliary reconstruction plate on the horizontal connecting rod of pressurization before bolt, auxiliary reconstruction plate is provided with at least two auxiliary fixing holes, be plugged with auxiliary sacrum pedicle of vertebral arch pulling force nail in the auxiliary fixing hole of one of them, it is applicable to bilateral sacroiliac joint fixing of fracture dislocation simultaneously.
