Abstract
The utility model discloses a spinal fixture transverse connector. The transverse connector comprises two clamping seats, wherein, each clamping seat is equipped with a clamping groove with a downward opening and a through cross link groove; the cross link grooves are positioned above the clamping grooves, and the through direction of the cross link grooves is perpendicular to the extension direction of the clamping grooves; a cross link is inserted between the two cross link grooves; and each clamping seat is also equipped with a lock bolt for locking the cross link. The transverse connector can be directly clamped on a nail stick, thus the connector is fast and convenient for assembly so as to indirectly improve the success rate of surgery and the restoration effect of patients.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, is meant that especially a kind of spinal fixation uses horizontal connected device.
Background technology
At present, in spinal operation, generally will use nail-stick system and fix, nail-stick system generally comprises two nail rods, and the two ends of nail rod are equipped with a screw, and screw is screwed in the spinal column, needs to install horizontal connected device between two nail rods.The effect of horizontal connected device is that two nail-stick systems that are installed in the spinal column both sides are connected and fixed, and reaches the effect of held stationary.If horizontal connected device is not installed, the consequence of fixing failure the vertebral body unstability may appear.The structure of present then horizontal connected device generally is to comprise two hooks 1, is connected with tranverse connecting rod 2 between the said hook 1, links up with 1 below and has and collude groove 3; Hook 1 is to catch on the nail rod from following closely an excellent side; Such installation bothers very much, and the sclerotin processing on the excellent both sides of nail very totally could be colluded horizontal connected device on the rod of both sides, and the time of usefulness is longer relatively; Spinal operation patient blood loss is more relatively; Delay one minute on the operating-table, patient is with regard to the danger of bull point more, thereby may influence the success rate of operation and the effect of operation.
The utility model content
This utility model technical problem to be solved is: provide a kind of spinal fixation to use horizontal connected device, this horizontal connected device can directly be stuck on the nail rod, and is quick and easy for installation, thus the effect that the success rate of indirect raising operation and patient recover.
For solving the problems of the technologies described above, the technical scheme of this utility model is: a kind of spinal fixation is used horizontal connected device, comprises two decks; Said each deck is provided with the draw-in groove that Open Side Down; Each deck is provided with the tranverse connecting rod groove of perforation, and said tranverse connecting rod groove is positioned at the top of draw-in groove, and the perforation direction of tranverse connecting rod groove is vertical each other with the bearing of trend of draw-in groove; Be fitted with tranverse connecting rod between said two tranverse connecting rod grooves, said each deck is provided with the clamping screw of the said tranverse connecting rod of locking.
As a kind of preferred scheme, said deck comprises two locking feets, and said each locking feet is provided with one section arc groove face, and two sections arc groove faces constitute said draw-in groove.
As a kind of preferred scheme, the bottom groove face of said tranverse connecting rod groove is provided with respectively two of tiltedly extending below to the centre from deck left surface and right flank and clamps application of force inclined-planes.
After having adopted technique scheme, the effect of this utility model is: because said spinal fixation is used horizontal connected device, comprise two decks; Said each deck is provided with the draw-in groove that Open Side Down, and each deck is provided with the tranverse connecting rod groove of perforation, and said tranverse connecting rod groove is positioned at the top of draw-in groove; And the perforation direction of tranverse connecting rod groove is vertical each other with the bearing of trend of draw-in groove, is fitted with tranverse connecting rod between said two tranverse connecting rod grooves, and said each deck is provided with the clamping screw of the said tranverse connecting rod of locking; Therefore, in the time of on the nail rod that horizontal connected device is installed in the spinal column nail-stick system can from follow closely rod above install, draw-in groove is stuck on the nail rod; Like this, the doctor need not the sclerotin of following closely excellent both sides is cleared up, thereby has reduced patient's misery; Quick and easy for installation, the success rate of indirect raising operation and the effect that the patient recovers.
Again since the bottom groove face of said tranverse connecting rod groove be provided with respectively from two clamping application of force inclined-planes that deck left surface and right flank tiltedly extend below to the centre, therefore, during installation; Can head on tranverse connecting rod when tightening clamping screw and clamp the slip of application of force inclined-plane to the lower edge; Because draw-in groove comprises two locking feets, therefore, tranverse connecting rod just makes two locking feets produce clamping forces in extruding clamping application of force inclined-plane; Thereby effectively clamped spiked is excellent, thereby improves the fixed effect of nail-stick system.

The specific embodiment
Through specific embodiment this utility model is done further to describe in detail below.
Upper and lower, left and right in this utility model are confirmed during with tranverse connecting rod 2 horizontal arrangement, and are as shown in Figure 2.
A kind of spinal fixation is used horizontal connected device, as shown in Figures 2 and 3, comprises two decks 1; Said each deck 1 is provided with the draw-in groove 3 that Open Side Down; Each deck 1 is provided with the tranverse connecting rod 2 groove (not shown)s of perforation, and said tranverse connecting rod 2 grooves are positioned at the top of draw-in groove 3, and the perforation direction of tranverse connecting rod 2 grooves is vertical each other with the bearing of trend of draw-in groove 3; Be fitted with tranverse connecting rod 2 between said two tranverse connecting rod 2 grooves, said each deck 1 is provided with the clamping screw 5 of the said tranverse connecting rod 2 of locking.Said clamping screw 5 is hexagonal clamping screws 5 in adopting.
Said deck 1 comprises two locking feets 31, and said each locking feet 31 is provided with 32, two sections arc groove faces of one section arc groove face 32 and constitutes said draw-in groove 3.The bottom groove face 32 of said tranverse connecting rod 2 grooves is provided with respectively two of tiltedly extending below to the centre from deck 1 left surface and right flank and clamps application of force inclined-planes 4.
The operation principle of this utility model is: in the operation; Nail-stick system is fixed on spinal column needs fixed position, is stuck on the nail rod from the top of following closely rod with the deck 1 of horizontal connected device then, and tranverse connecting rod 2 is inserted in tranverse connecting rod 2 grooves; Tighten clamping screw 5 then; Clamping screw 5 compresses tranverse connecting rod 2, makes the tight application of force of tranverse connecting rod 2 effects inclined-plane, produces both direction respectively to intermediary clamping force through clamping 4 pairs of two locking feets 31 in application of force inclined-plane; Thereby make two locking feets 31 clamp said nail rod, good fixing effect.Deck 1 is installed from following closely the rod top, and is quick and easy for installation, thereby reduced patient's misery, the success rate of indirect raising operation and the effect that the patient recovers.
