On a ball 315, the base 31 is provided with through hole in the relative position of the blind hole, when retainer ring 4 is located in described lead to
When in groove 312, with reference to figure 6, the ball 315 can allow connector 3 and retainer ring 4 by through hole top pressure in the retainer ring 4
Between relative movement produce resistance, avoid connector 3 from arbitrarily being slided in retainer ring 4.
In the present embodiment, as shown in fig. 7, being provided with for the ease of the installation retainer ring 4 of connector 3 for wearing
The opening 41 of connector 3.
As shown in Figure 7, the front end of pull bar 5 in the present embodiment is connected with retracting plate 1, and rear end is screw rod, passes through screw rod and behaviour
Make handle threads connection, person easy to operation applies external force.
In operation technique, with reference to Fig. 1-Fig. 8, illustrated in the present embodiment using three traction components, this practicality is new
The application method of type is：
1) pull bar 5 is threadedly coupled with operation handle, then tissue pulled；If necessary to coordinating push pedal device
6 are pulled.
2) after traction plate 1 is pulled to specified location, then centrum stabilization needle 2 is inserted in the spacing hole 11 for retracting plate 1 respectively,
Centrum stabilization needle 2 is screwed into by centrum by its thread head 21 by spanner, until the fixture block 22 of centrum stabilization needle 2 is pressed on traction
On plate 1, and then retract connecting firmly for plate 1 and centrum.
3) the traction plate 1 for respectively retracting component is completed after installing, and connector 3 is arranged on into retainer ring 4 by its groove 312
On, now the clamping cap 34 on connector 3 is non-tightening state, and column sleeve 32 can move along column 311.Hereafter, will be every
Individual pull bar 5 is respectively implanted in the holding tank 332 of the C-clamp device 33 of correspondence position, i.e., as shown in fig. 6, when the position of three pull bars 5
Put after primarily determining that, clamping cap 34 screwed using spanner, in screwing operations, operator adjust manually the position of column sleeve 32 with
And the position of C-clamp device 33, most column sleeve 32 holds column 311 tightly at last, while the stable holding of pull bar 5, realization are connected firmly.Three
Position of the component in retainer ring 4 is retracted to be determined, and mutual position is limited by retainer ring 4,
Therefore position will not change.
4) finally, the operation handle on pull bar 5 is removed, vacates operating space, carries out related surgical operation.
In the utility model, after step 3) is completed, centrum stabilization needle 2 and centrum keep connecting firmly relation, retract plate 1 with
Centrum stabilization needle 2 is kept connecting firmly relation, and the relative position retracted between plate 1 is determined also by retainer ring 4, therefore a whole set of
Device forms a stable assembly, it is not necessary to is connected firmly with operating table bedstead, improves the flexibility used, is also operation
Bring great convenience.
In summary, the multidirectional pull device of the present utility model for spinal surgery, during use need not and hand
Art platform bedstead connect, and using when be conveniently adjusted retract plate position.So the utility model effectively overcomes prior art
In some practical problems so as to having very high value and using meaning.
Above-mentioned embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.The utility model also has many aspects to be improved on the premise of without prejudice to overall thought, for being familiar with this technology
Personage all can carry out modifications and changes to above-described embodiment without prejudice under spirit and scope of the present utility model.Therefore,
Such as those of ordinary skill in the art is without departing from the spirit disclosed in the utility model and institute under technological thought
All equivalent modifications completed or change, should be covered by claim of the present utility model.
