Abstract
The utility model relates to a fixing system for scoliosis treatment. The fixing system comprises a central screw, a pair of double-end universal joint arranged on the central screw, first extension pipes which are arranged on two sides of the central screw symmetrically by the double-end universal joint, a second extension pipe which is connected with the first extension pipes by a casing pipe and single-end universal joints arranged on the outer side end of the second extension pipe, wherein the two single-end universal joints on the same side are arranged on a far-end screw; the central screw is connected with a fixed rod by a long bolt; and one end of the long bolt is provided with a butterfly nut for regulating space between the central screw and the fixed rod. Tissue which is adhered can be peeled under the traction action of the central screw and the fixed rod to fulfill the aim of restoration. By the fixing system, the success rate of surgeries can be improved substantially, the surgical operation is simplified greatly, and surgical time and the rehabilitation period of patients are shortened.
Description
Technical field
This utility model relates to orthopaedics and uses technical field of medical, specifically is that fixed system is used in a kind of scoliosis treatment.
Background technology
Scoliosis departs from midline of body with a certain section of spinal column usually enduringly, makes spinal column be the main disease that shows to side protrusion arc or serpentine.
It is crooked to the side that scoliosis is meant that one of spinal column or several sections depart from midline of body on coronalplane; Form a deformity of spine that has radian; Usually also with the increase or the minimizing of processus aboralis or prolapse on the rotation of spinal column and the sagittal plane; Also have simultaneously height about rib does not wait other ligament of rotation inclination deformity and the vertebra of flat, pelvis and muscle unusually, it is a kind of symptom or X line sign, can be caused by multiple disease.Skoliosis betides the vertebra between cervical vertebra, thoracic vertebra or chest and the waist usually, also can betide lower back separately.Lateral bending appear at spinal column one side, be " C " type; Or, be " S " type in the bilateral appearance.It can reduce the cubical content of thoracic cavity, abdominal cavity and pelvic cavity, also can reduce height.
Therefore, how providing a kind of scoliosis treatment to use fixed system, is the technical barrier of this area.
The utility model content
This utility model technical problem to be solved provides a kind of scoliosis treatment simple in structure, that clinical manipulation is easy, safety and reliability are higher and uses fixed system.
For solving the problems of the technologies described above; This utility model provides the treatment of a kind of scoliosis use fixed system, comprising: central screw, be located at a pair of double end universal joint on this central authorities' screw, be symmetrically set in first of central screw both sides through this double end universal joint and prolong pipe, second prolong pipe, be located at the single head universal joint that outboard end is managed in this second prolongation through what a sleeve pipe and this first prolonged that pipe links to each other; Two single head universal joints of homonymy are located on the distal screw.
Further, said single head universal joint is fixed on the distal screw through pressing closer screw, presses closer the height that screw is suitable for adjusting said single head universal joint through this, to satisfy the clinical practice requirement.
Further, said double end universal joint is fixed on the central screw through lock-screw, is suitable for adjusting the height of said double end universal joint through this lock-screw, to satisfy the clinical practice requirement.
Adopt bolt between said sleeve pipe and said first, second prolongation pipe, with further raising stability and reliability.
Further, said central screw links to each other with a fixed bar through a stay bolt, and an end of stay bolt is provided with the wing nut that is used to regulate said central screw and fixed bar spacing; Through the draw of central screw and fixed bar, the tissue that has sticked together is peeled off, reach the purpose that resets.
The utlity model has positive effect: fixed system is used in the scoliosis treatment of (1) this utility model, and the draw that produces through central screw and fixed bar during use can make the tissue that has sticked together peel off, and reaches the purpose that resets.After traction, use necessary brace to force the spinal stabilization that has resetted constant, retraction does not take place change, the effect that enlarges interbody space is also arranged.Native system can significantly improve success rate of operation, has simplified operation technique greatly, shortens operating time and rehabilitation of patients cycle.
Description of drawings
Fig. 1 is that the scoliosis among the embodiment is treated the structural representation with fixed system;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the assembling sketch map of said scoliosis treatment with fixed system.
The specific embodiment
See Fig. 1, the treatment of the scoliosis of present embodiment comprises with fixed system: central screw 11, be located at a pair of double end universal joint 8 on this central authorities' screw 11, be symmetrically set in first of central screw 11 both sides through this double end universal joint 8 and prolong pipe 7, second prolong pipe 5, be located at this and second prolong the single head universal joint 4 of managing 5 outboard ends through what a sleeve pipe 6 and this first prolonged that pipe 7 links to each other; Two single head universal joints 4 of homonymy are located on the distal screw 3.
Said single head universal joint 4 is fixed on the distal screw 3 through pressing closer screw 1.
Said double end universal joint 8 is fixed on the central screw 11 through lock-screw 4.
Said sleeve pipe 6 and said first, second prolong pipe 7, adopt bolt 12 fixing between 5.
Said central screw 11 links to each other with a fixed bar 10 through a stay bolt 9, and an end of stay bolt 9 is provided with the wing nut 11 that is used to regulate said central screw 11 and fixed bar 10 spacings.Fixed bar 10 two ends are provided with screw, to be fixed on spinal column one side.
The draw that produces through central screw and fixed bar during use can make the tissue that has sticked together peel off, and reaches the purpose that resets.After traction, use necessary brace to force the spinal stabilization that has resetted constant, retraction does not take place change, the effect that enlarges interbody space is also arranged.Native system can significantly improve success rate of operation, has simplified operation technique greatly, shortens operating time and rehabilitation of patients cycle.
Obviously, the foregoing description only be for explain clearly that this utility model does for example, and be not to be qualification to the embodiment of this utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these spirit that belong to this utility model are extended out or change still are among the protection domain of this utility model.
