Description
Technical field
This utility model relates to the orthopaedics technical field of medical instruments, particularly relates to a kind of fixation device that is used for fracture-dislocation of cervical spine.
Background technology
Impaired the resetting of cervical vertebral body at present, slight person can adopt simple traction to reset, but reset for irreducible, be the simple traction unsuccessful person that resets, after the clinical general employing way of escape is cut simple and easy apparatus and is resetted, capable more preceding road intervertebral bone-graft fusion, like this then cause the generation of second operation, not only increase the patient suffering, and need keep reset position and could guarantee intervertebral by hand for a long time, by simple apparatuses such as dilators, need during operation to keep the position by hand for a long time, could guarantee the success of intervertebral bone-graft fusion, operation easier is big, waste time and energy, easily cause operative failure or reset undesirable.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provides a kind of once operation can finish the positor that fracture-dislocation of cervical spine resets, thereby reduces operating difficulty, reduces the patient suffering, improves surgical effect.
For achieving the above object, this utility model fracture-dislocation of cervical spine positor, have rear side and have the slide bar of regulating tooth tooth, one end of slide bar is fixed with the support bar of band obtuse angle bending, the front end of support bar is equipped with hold-down screw, also by slide block another support bar consistent with above-mentioned support bar shape is installed on slide bar, a side of slide block is connected with the adjusting slider on being contained in slide bar.On adjusting slider, be equipped with and regulate the adjusting gear and the adjusting knob of teeth engagement, locating detent also is housed on the adjusting slider.Have by clamp to be installed in bar supporter on the slide bar between above-mentioned two support bars, in the screwed hole on bar supporter top adjusting rod is installed, the adjusting rod postmedian is threaded, and its rear end has adjusting knob, and front end is equipped with forcing screw.
Fracture-dislocation of cervical spine positor as mentioned above, head is installed for not threaded screw in the front portion of its adjusting rod, screw is installed on the head and also is processed with slotted hole, the forcing screw mounting blocks is sleeved on screw by limited post the head outside is installed, in the aperture on screw installation head spacing steel ball is housed, in the axial hole of screw installation head spring is housed, forcing screw is inserted in the screw installation head and by spacing steel ball and blocks.
This utility model is on existing anterior cervical vertebrae vertebral body tractor basis, adjusting rod and adjusting knob have been increased, strut screw by two pieces of original vertebral bodys, be improved to two pieces of vertebral body hold-down screws and one piece of pressure pulling screw, control by adjusting knob, it is being strutted on the basis of intervertebral space, can pressurize or lift the dislocation vertebral body, be convenient to fracture dislocation and reset, keep the spinal column normal sequence, and can keep reset position for a long time, guarantee that bone grafting, steel plate placement location are accurate.Once operation can be finished resetting of fracture-dislocation of cervical spine, thereby reduces operating difficulty, reduces the patient suffering, improves surgical effect.This utility model is simple in structure, and the doctor is easy to grasp operational approach, is convenient to popularize.
