Description
Technical field;
This utility model relates to medical apparatus and instruments, the anterior cervical vertebrae positor that uses in especially a kind of cervical vertebra reattachment surgery.
Background technology:
At present, dislocation of cervical vertebra is carried out using when anterior approach resets the Caspar distraction reduction device.The Caspar distraction reduction device can only play the intervertebral pulling effect, and the reset response of displacement is poor before and after between vertebral body, so for twisting the lock joint dislocation difficulty that resets sometimes.
Summary of the invention:
The technical problems to be solved in the utility model is: provide a kind of easy to operate, resetting is easy to the anterior cervical vertebrae positor, carries out anterior approach when resetting in dislocation of cervical vertebra, can easier carry out resetting of joint strand lock.
The technical scheme that addresses the above problem employing is: a kind of anterior cervical vertebrae positor, comprise tooth plate, strut gear, positioning clamping pin, support arm, strut pipe, strut nail, wherein a support arm one end and tooth plate are fixed and are constituted fixed arm, another support arm one end and the fixing formation of the travelling carriage that struts gear transfer arm, the other end of described fixed arm and transfer arm is equipped with the pipe that struts of the perpendicular two ends perforation that is connected respectively, and two strut the pipe epimere is provided with female thread; Strut nail by roof pressure reset the nail and lift reset the nail form, the pipe box that struts that described roof pressure resets on nail its epimere bar portion and the fixed arm assembles and closes, this struts the pipe epimere roof pressure spanner with its screw-internal thread fit is housed, the pipe that struts on the transfer arm passes in described its bar portion of nail that resets that lifts, and its epimere is equipped with the spanner that lifts that is connected with its screw structure.
Compare with existing Caspar distraction reduction device, the beneficial effects of the utility model are: descend on the implementation in the vertebra reseting procedure, if because of two vertebras are in pushing up the position can not normally reset the time, nail on rotation to lift spanner lifting to reset, so that position, back vertebral body is lifted forward, and/or screw in another with the roof pressure spanner and retract pipe, with roof pressure reset the nail related anteposition vertebral body push the rear to, observe two vertebra leading edges when flushing, the position that C-arm machine is observed articular process is a normal anatomical relationship, and then examination pine part retracts gear, observes the position between the vertebral body, upper vertebra no longer moves forward, and the vertebra of dislocating as can be known resets.Therefore, this utility model is simple to operate, and reset effect is satisfied.
Description of drawings:
Fig. 1 is an assembly structure sketch map of the present utility model.
Among the figure: tooth plate 1, travelling carriage 2 struts gear 3, positioning clamping pin 4, transfer arm 5 fixed arms 6, roof pressure spanner 7 struts pipe 8, and roof pressure resets and follows closely 9, lifting the nail 10 that resets, and lifts spanner 11.
The specific embodiment:
Below in conjunction with accompanying drawing, be fixed as example with the preceding road of the C5 anterior dislocation row intervertebral bone grafting titanium plate that resets, the utility model is described in further detail:
As shown in the figure, tooth plate 1, travelling carriage 2, strut gear 3, positioning clamping pin 4 is identical with Caspar distraction reduction device corresponding component structure, it is tabular that tooth plate 1 also is bar shaped, one wears tooth, on it by travelling carriage 2 be equipped with its engagement strut gear 3, strut gear 3 and have rotary switch, positioning clamping pin 4 is housed on the travelling carriage 2.
Fixed arm 6 is a straight-arm, and the one end is fixedlyed connected with tooth plate 1, and the other end has through hole; Transfer arm 5 also is a straight-arm, and the one end is sleeved on the tooth plate 1 and with travelling carriage 2 and is a slip integral body, and the other end of transfer arm 5 also has through hole.
Strut pipe 8 for hollow, can hold strutting nail bar portion, screw thread is arranged in the epimere, the spanner that is used to the reset usefulness that resets.Two strut pipe 8 respectively by the fixedly integral body of the through hole on fixed arm 6 and the transfer arm 5 with fixed arm 6 and transfer arm 5 formation connecting lever structures.
There is the part tapping screw thread reset nail 9 and lift the nail 10 that resets and be two and strut nail of roof pressure, roof pressure nail 9 its lower ends that reset, are used to be screwed in the vertebral body and use; The upper end of its threaded portion increases thick formation back-up ring structure, struts the degree of depth that nail enters vertebral body with control; Back-up ring structure top is outer six side's shapes, is convenient to be screwed into when strutting nail and uses; Yardstick is carved with in bar portion, the distance that resets with observation.It is long than the roof pressure nail 9 that resets to lift the nail 10 bar portions that reset, and following middle part shape is with the roof pressure nail 9 that resets, and epimere is screw structure, usefulness when lifting.Pipe 8 suits that strut that roof pressure resets on nail 9 epimere bar portions and the fixed arm 6 cooperate, and this struts manages 8 epimeres roof pressure spanner 7 with its screw-internal thread fit is housed; Lift nail 10 its bar portions that reset and pass and strutting pipe 8 on the transfer arm 5, its epimere be equipped be connected with its screw structure lift spanner 11.Roof pressure spanner 7 is used for the roof pressure usefulness that resets, and lifts spanner 11 and is used to lift the usefulness that resets.
Operating process is summarized as follows:
The patient lies on the back, and keeps skull traction, and conventional preceding road appears hinders vertebra.See that the reach of C5 vertebral body exceeds the about 1CM of C6 vertebral body, C-arm machine is observed C5/6 articular process position, and the C5 inferior articular process jumps to C6 superior articular process the place ahead and is strand lock shape.In C5, the mid point perforate of C6 vertebral body front, the roof pressure nail that resets 9 is screwed into the C5 vertebra with gag, lifts the nail 10 that resets and being screwed into the C6 vertebra, with reset nail 9 and lift the nail 10 bar portions that reset and be inserted in and strut pipe 8 of roof pressure.At first rotate and strut the gear 3 upper and lower intervertebral spaces that strut, with the fibrous ring that sharp knife cuts the damage sections, the excision nucleus pulposus, tentative once more dilator struts, and part patient can reset this moment.If can not reset, C-arm machine is observed the articular process position and often is in the position, top.Then lift rotation on the nail 10 that resets at C6 to lift spanner 11, so that position, back C6 vertebral body is lifted forward, and/or screw in C5 roof pressures the strutting in the pipe 8 on the nail 9 that reset with roof pressure spanner 7, with roof pressure reset the nail 9 related anteposition C5 vertebral bodys push the rear to, when noticing that simultaneously observation two anterior margin of vertebral body and two scale sizes that strut on the nail bar flush, the position that C-arm machine is observed articular process is normal anatomical relationship (the C5 inferior articular process is back to C6 superior articular process rear).The examination pine struts gear 3, observes the position between the vertebral body, and the C5/C6 leading edge is concordant, and upper vertebra no longer moves forward, and the vertebra of dislocating as can be known resets.Continue to implement next operating procedure (bone grafting, titanium plate are fixed).
