Drop, movement are more steady.Recessing groove 420 can not also be set, and directly in the lower end both sides of upper plate 40, setting sets two respectively and hangs
First sliding eye 410 is opened on lifting lug by ear.
The upper surface of the upper plate 40 is equipped with anti-slop serrations 430, and the lower face of lower plate 50 is equipped with anti-slop serrations 530, and on
Mounting hole 440 is further opened on the upper surface of plate 40, mounting hole (not shown) is further opened on the lower face of lower plate 50, side
Just it is put into bone-grafting material.
As shown in Fig. 4 to 7, the threaded fusion cage further includes rotating mechanism 80, and the rotating mechanism 80 includes spiral shell core
810th, sandwich 820 and chuck 830, the spiral shell core 810 are connect with one end of screw rod 30, and the lower plate 50 is close to the end of spiral shell core 810
Face is equipped with folder support 540 or the outer end face of the first sliding block 60 close to spiral shell core 810 is equipped with folder support (not shown), described
Sandwich 820 is set in outside spiral shell core 810 and is threadedly coupled with spiral shell core 810, and one end of the sandwich 820 is clipped in outside support 540, and institute
It is towards 60 inclined inclined-plane of the first sliding block to state the surface that folder support 540 is contacted with sandwich 820, and the chuck 830 is set in sandwich 820
It is threadedly coupled outside and with sandwich 820, the chuck 830 makes the locking folder support 540 of sandwich 820 towards the rotation of the first sliding block 60.Rotate spiral shell
Core 810 drives screw rod 30 connected to it to rotate, so as to make the first sliding block 60 being threadedly coupled with screw rod 30, the second sliding block 70
It mutually draws close or detaches along screw rod 30, the front end sleeve of the sandwich 820 is in folder support 540, due to folder support 540 and sandwich 820
The surface of contact is towards 60 inclined inclined-plane of the first sliding block, and the front end of sandwich 820 offers the clip slot 822 along its axial direction,
So chuck 830 constantly oppresses the sandwich 820 of 822 both sides of clip slot while rotation towards the first sliding block 60, make the locking folder of sandwich 820
Support 540, spiral shell core 810 are rotated relative to sandwich 820, if folder support is arranged on the first sliding block 60,820 and first sliding block 60 of sandwich is same
Moved further, if folder support 540 is arranged in lower plate 50, since lower plate 50 is fixed, sandwich 820 does not move position relative to screw rod 30
It puts, by the way that sandwich 820 is set to be connect with folder support 540, makes screw rod 30 lighter in rotary course, and make upper plate 40 and lower plate
50 remain fixed position.
The rotating mechanism 80 further includes housing 840 and fixture block 850, the housing 840 be set in the sandwich 820 it is outer and
It is slidably matched with the sandwich 820, the housing 840 offers the card slot 842 in radially direction, the spiral shell core 810 and institute
842 corresponding position of card slot is stated equipped with annular groove 812, the fixture block 850 is fastened on across card slot 842 on the annular groove 812.
It being stuck on card slot 842 and annular groove 812 due to being provided with fixture block 850, the spiral shell core 810 rotates phase to 840 rotation of housing, and
Sandwich 820 can horizontally slip with respect to housing 840, slide it is steady, to adapt to the variation of 540 position of folder support, the sandwich 820 with it is outer
It is in polyhedral to cover 840 corresponding core section outer surfaces, is in hexahedron shape in the present embodiment, naturally it is also possible to be other shapes, such as
Pentahedron, heptahedron etc., inner surface and the polyhedral core section shiding matching of the housing 840, in this way, making sandwich 820
It can only horizontally slip with respect to housing 840, without rotating.
The torque force limiting device 870 that the rotating mechanism 80 further includes handle 860 and is arranged on handle 860, the spiral shell
The housing 840 is stretched out, and the one end of spiral shell core 810 far from screw rod 30 connects with the handle 860 in the one end of core 810 far from screw rod 30
It connects.Spiral shell core 810 is driven to rotate by rotating handle 860, the torque force limiting device 870 is to limit torsion, controls lifting force
Degree, i.e., when reaching certain dynamics, can not twist, and handle 860 is avoided to rotate excessively, and ratchet etc. can be selected and limited as torsion
Device.In the present embodiment, 860 front end of handle is equipped with bar-shaped trough, and one end that the spiral shell core 810 is connect with handle 860 is in and institute
The matched kidney-shaped of bar-shaped trough is stated, spiral shell core 810 is made to link with handle 860, is not relatively rotated between the two.It is corresponding, it is described
The front end of spiral shell core 810 also is provided with bar-shaped trough, and one end that the screw rod 30 is connect with spiral shell core 810 is in and 810 front end bar-shaped trough of spiral shell core
Matched kidney-shaped makes screw rod 30 link with spiral shell core 810, does not relatively rotate between the two.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
