To expand fusion device；According to circlip, support chip energy slight displacement, the eyelid retractor is elastic supporting device between vertebra.With
Between vertebra exemplified by the use of elastic supporting device, in order to effectively utilize the elastic characteristic of back-up ring itself, support chip is smoothly sent out
Component, for the back-up ring used for circlip 19, its tail end is provided with rear spacing ring 5.Meanwhile it is provided with circlip 19 anti-
Locking mechanism.Specifically, circlip 19 can be formed using trapezoidal spring boss, is provided with trapezoidal spring boss anti-
Locking mechanism, anti-locking mechanism are separating tank.In such manner, it is possible to from meeting both to be stacked between each support chip to the full extent
Separable needs again.Also, according to rigid back-up ring, its structure can also be consistent with circlip 19.
During actual use, the eyelid retractor is inserted in intervertebral space, the handle 15 of propulsion assembly 14, main support chip after rotation
2nd, the V-arrangement support chip that secondary support chip 3 is formed is deformed upon and rotated.So, as shown in Figure 5, Figure 6, V-arrangement support chip can be made
Increase in X-axis, Y-axis both direction volume.In other words, V-arrangement support chip can slight shift and there is " elastic deformation ", so as to
As eyelid retractor between elastic vertebra.Similarly, circlip 19 is unable to deformation if rigidity, and V-arrangement support chip can not then be shifted and had
There is " rigid support ", so as to expand intervertebral spacers as eyelid retractor between rigid vertebra.
The operation principle of the present invention is as follows：
When it is implemented, the end of inner prop 4 with insert apparatus be connected and separate, operation it is as follows：
In order to realize effective transmission, the boss 18 and the respective slot 17 of the end of inner prop 4 of the interior front end of gag lever post 13 coordinate,
Realization prevents inner prop 4 from rotating.Meanwhile rely on and rotate internal lock tight set 12, make the internal thread 8 and inner prop 4 of the front end of internal lock tight set 12
The corresponding external screw thread 7 in end, be threadedly coupled.
Then, by the rear locking cap 16 of the interior tail end of gag lever post 13, interior gag lever post 13 can be connected with internal lock tight set 12
It is integrated, while prevents internal lock tight set 12 and inner prop 4 from rotating.So that eyelid retractor connects as one with inserting apparatus.
Then, the handle 15 of outer propulsion assembly 14 is further rotated.Thus, outer propulsion assembly 14 is made to be conducted by thrust,
Outer promote is promoted to cover 11.Specifically, conducted along with thrust, outer spacing ring 5 after promoting the propulsion of set 11.Now, spacing ring 5 pushes away
Enter circlip 19.Meanwhile the forced compression of circlip 19 is to certain position, and then promote secondary support chip 3.Secondary support chip 3 is logical
Exertin conduction promotes main support chip 2.
During this period, because the main front end of support chip 2 holds out against front catch member 1, the boss 9 on secondary support chip 3 promotes main support chip
2.Thus, main support chip 2 and secondary support chip 3 progressively increase due to the deformation height that is stressed, while main support chip 2 and secondary support chip
3 progressively separate with the positive stop lug boss 6 being distributed on inner prop 4 with highly increasing.And then the boss 9 on secondary support chip 3 be advanced into
To in the pockets 10 in main support chip 2.After main support chip 2 and secondary support chip 3 turn an angle with respect to inner prop 4, such as Fig. 6
It is shown.Meanwhile spacing ring 5 promotes circlip 19, until spacing ring 5 is entered in positive stop lug boss 6.With this, positive stop lug boss 6 prevents
Spacing ring 5 retreats, and then forms entirety after realizing eyelid retractor expansion.Also, upper centrum and hypocentrum are due to by main support chip 2
With the effect of the secondary deformation height thrust of support chip 3, make intervertebral space become big, and then realize operation purpose, reach the effect of good.
Further, in rotation the tail end of gag lever post 13 rear locking cap 16, can be interior gag lever post 13 and internal lock tight set 12
Disengage.Then, hold with a firm grip the interior tail end of gag lever post 13, the corresponding recessed of the boss 18 of the interior front end of gag lever post 13 and the end of inner prop 4 can be passed through
Groove 17 coordinates, and prevents inner prop from rotating.Meanwhile internal lock tight set 12 is rotated, make internal thread 8 and the end of inner prop 4 of the front end of internal lock tight set 12
The external screw thread 7 at end realizes that screw thread disengages.And then realize the end of inner prop 4 and insert fracture.
It is can be seen that by above-mentioned character express and with reference to accompanying drawing using after the present invention, gather around and have the following advantages：
1st, the presence of inner prop is relied on, while can carrying out spacing to support chip component, realizes effective Route guiding,
Meet the accuracy of installation site.
2nd, using circlip, the smooth traveling of support chip component is can guarantee that, is occurred without stuck.
3rd, some V-arrangement support chips form support chip component, meet actual expansion needs, possess preferable extending space.
4th, the difference construction of main support chip, secondary support chip is relied on, meets both firm linkings.
5th, it can realize that the X-axis of support chip, Y-axis both direction volume increase.
6th, unitary construction is simple, is easily assembled and onsite application.
7th, use range is wide, between spinal vertebral, the intervertebral support such as between zygapophysial joint and between spinous process.
Described above is only the preferred embodiment of the present invention, is not intended to limit the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is some improvement and
