Abstract
The utility model discloses a single-side bone outside fixing frame used for bone surgery medical treatment, which comprises a connecting sleeve, a draw rod assembly connected by the connecting sleeve, a supporting rod connected to the end part of the connecting sleeve through a ball shaft, and a nail locking device connected to the supporting rod, wherein, the rod part of the supporting rod forms a column shape, and the nail locking device is connected with a ball shaft seat which can slide and rotate on the supporting rod through the ball shaft; a locking device is arranged on the ball shaft seat. When the utility model is used, a bone needle can be in parallel needling and can also be in unparallel needling, and the utility model has the advantages of convenient operation and firm fixed force.
Description
This utility model relates to the fixedly surgical medical equipment of usefulness of a kind of reduction of the fracture.
At the bone external fixer of Orthopeadic Surgery medical domain is that intervention by nail links together knochenbruch and external support securely, thereby reaches the purpose of treatment fracture." practical orthopaedics and tranmstology " the 267th page of kind and form of having introduced bone external fixer commonly used that the People's Medical Officer Press publishes can be divided into: unilateral, bilateral formula, four limit formulas, semi-ring formula, loopful formula and trigonometric expression six big classes substantially.The most representative is the bone external fixer that Italian BASTIANI company makes, and this bone external fixer has telescopic rack body, is socketed with the longitudinal axis on the rack body, and the longitudinal axis is provided with the pinning device that spherical joint connects; Because rack body is scalable, and the longitudinal axis is provided with spherical joint, more increased the motility of support, and it is easier that knochenbruch is resetted.The shortcoming of this bone external fixer is: nail can only translation on support bar and can not be rotated, so necessary parallel inserting needle of many nails on same support bar, require high to the direction of threading a needle, there is deflection promptly can not be connected slightly with fixed mount, can not be applicable to the multistage complicated fracture, in addition: because the necessary parallel inserting needle of this fixed mount, it is firm to be not so good as non-parallel inserting needle from the mechanics bed knife.
The purpose of this utility model provides the one-sided bone external fixer that a kind of multi-directionally is threaded a needle, bed knife is firm
In order to achieve the above object, just must make that spicule can multi-directional rotation on support bar and move, the technical solution adopted in the utility model is as follows: the rod assembly that one-sided bone external fixer described in the utility model comprises adapter sleeve, connected by adapter sleeve, by ball journal be connected the adapter sleeve end support bar, be connected the pinning device on the support bar, the bar portion of support bar is cylindrical, the pinning device is by ball journal and can slide on support bar and be connected with the ball and socket base that rotates, and has locking device on the ball and socket base.
Above-mentioned locking device can be an eccentric bolt, also can be fastening bolt.
After adopting such scheme, also there is the transverse axis joint on the support bar in the existing longitudinal axis of one-sided bone external fixer described in the utility model joint, and be can be multi-direction the ball journal joint of multi-angle rotation, just can change the length of rod assembly by the length that changes adapter sleeve; Unclamp locking device, the spacing that the pinning device both can slide and thread a needle with change on support bar can be rotated selecting the suitable direction of threading a needle around support bar again, not only can parallel inserting needle but also can non-parallel inserting needle.In sum, one-sided bone external fixer described in the utility model has the advantage that multi-directionally is threaded a needle, bed knife is firm.
Further specify this utility model below in conjunction with drawings and Examples:
Accompanying drawing is the cutaway view of an embodiment of the present utility model.
As shown in drawings, one-sided bone external fixer described in the utility model comprises an adapter sleeve 1, and by the rod assembly 7 that adapter sleeve 1 connects, the two ends of this adapter sleeve 1 are ball and socket bases 8, and the end of support bar 2 is the bulb that is installed in the ball and socket base 8, and bar portion is cylindrical; One end of pinning device 3 is a bulb, this bulb is installed in the ball and socket base 6, the other end of ball and socket base 6 is and the corresponding cylindrical shape of the cross sectional shape of support bar 2, and be socketed on the support bar 2, have locking device on the ball and socket base 6, this locking device is an eccentric nut, can lock bulb and ball and socket base 6 simultaneously during the locking eccentric nut.
Eccentric nut clamp device on the above-mentioned ball and socket base also can adopt other fastening methods, as fastening bolt, alignment pin etc.
During use, at first adjust adapter sleeve 1 and rod assembly 7, be fixed in the length that needs; Adjust the position of ball and socket base 6 then, ball and socket base 6 can slide on support bar 2 and also can rotate around it, and the bulb of pinning device also can rotate in ball and socket base 6, therefore, the nail on same support bar can parallel inserting needle also can not parallel inserting needle; After adjusting the direction of the position of ball and socket base 6 and spicule, the locking locking device gets final product.
