Abstract
The utility model relates to a universal adjustable fracture outer fixer. Two pairs of steel nail fixing devices are installed on a main fixing shaft, and each fixing device comprises a clamp. One end of the clamp is clamped on the main fixing shaft, and the other end is provided with a groove with a spherical face. A steel nail fixing shaft, on which a steel nail hole is bored is connected with a steel ball arranged in the groove and a steel nail locking device is also arranged on the shaft. The position and the direction of a nail fixing hole can be arbitrarily adjusted by the utility model, and boring distance and direction are not severely restricted by the fixer in operation. Thus the operation difficulty is reduced, the fracture healing can be accelerated and the course of treatment is shortened.
Description
This utility model belongs to the utensil technical field that is used for synthetism.
External fixation of fracture is the fracture fixation method that was widely adopted in recent years.What clinical practice at present was more is four nail external fixators of middle adjustable-length and angle, because the staple groove of its every end is parallel, and spacing changes also has only several fixed dimensions, the staple that requires to plant the people during operation must be parallel fully, thereby operation easier is big, often cause the resistance between fracture end rotation sidesway or nail and nail, influence therapeutic effect.The patent No. is that 92235835.4 " adjustable long bone fracture external fixator " and the patent No. are 93209751.0 " one-sided adjustable fracture external fixator " though it has been done improvement, but still has operation inconvenience and the not good enough defective of result of use.
The purpose of this utility model provides a kind of position of four staple holes and the universal adjustable fracture external fixator that direction can arbitrarily be adjusted, thereby reduces operation easier, improves therapeutic effect.
For achieving the above object, technical solution adopted in the utility model is that the position in two pairs of staple holes and the steel nail fixture that direction can be adjusted arbitrarily are installed on main fixed axis, this steel nail fixture comprises that an end is clipped in the clip on the main fixed axis, the other end of clip has spherical groove, steel ball is installed in the groove, constitute a universal joint, be connected with the steel nail fixed axis that has the steel nail hole on it on the steel ball, also have the steel nail locking device on the steel nail fixed axis.
The utility model has the advantages that: realized the position in four staple holes and the random adjustment of direction, make distance, the direction of holing in the operation limited by the strictness of holder, thereby greatly reduce operation easier, can not cause the power that creates antagonism between fracture end rotation sidesway or nail and nail, also can utilize mechanical pulling force that fracture site is involutory closely after holder is first-class, thereby the healing rate that can accelerate to fracture shortens the course of treatment.
Below in conjunction with drawings and Examples, structure of the present utility model is described in further detail.
Fig. 1 is a front view of the present utility model, shows its overall structure;
Fig. 2 is the front view of another embodiment of this utility model;
Fig. 3 is this utility model front view of an embodiment again;
In the embodiment that Fig. 1 provides, main fixed axis 1 of the present utility model is a cylindrical major axis, two steel nail fixtures 2 respectively are installed on the two parts of the left and right sides of main fixed axis 1, each steel nail fixture 2 includes an end and is clipped in clip 7 on the main fixed axis 1, the end in addition of clip 7 has spherical groove, steel ball 6 is housed in the groove, be connected with steel nail fixed axis 5 on the steel ball 6, have steel nail hole 3 and steel nail locking device 4 on the steel nail fixed axis 5, this steel nail locking device 4 is one to be installed in the holding screw of steel nail fixed axis 5 ends.Clip 7 is made of symmetric two halves, and lock-screw 8 is equipped with at clip 7 middle parts, and after lock-screw 8 tightened, the upper end of clip 7 was fixed on the main fixed axis 1, and the lower end is fixedly clamped steel ball 6.
In the embodiment that Fig. 2 provides, main fixed axis 1 comprises left and right sides two-semiaxle 9,10, one end of left half axle 9 is fixed with the end by screw 12 and has externally threaded adapter sleeve 11, the end that right axle shaft 10 is corresponding with it is equipped with the adjustment medicated cap 13 that is connected with adapter sleeve 11 by screw thread by circlip 14, the cross sectional shape that left and right sides two-semiaxle 9,10 is positioned at the part of adapter sleeve 11 is semicircle, and these two parts overlap.Steel nail locking device 4 constitutes by being contained in the eccentric lock mandrel 15 in and the hole that is communicated with vertical with steel nail hole 3 and the stop screw 16 of steel nail fixed axis 5 ends.The structure of remainder is same as the previously described embodiments.Rotate and adjust medicated cap 13, can make the two-semiaxle relative motion, thereby can utilize mechanical pulling force that fracture site is involutory closely.
In the embodiment that Fig. 3 provides, main fixed axis 1 also comprises left and right sides two-semiaxle 9,10, the end that two-semiaxle is relative has the opposite screw thread of rotation direction, is linked together by a double rotational directions nut 17, and respectively there is a back of the body medicated cap 18 that is contained on the two-semiaxle of the left and right sides at the two ends of double rotational directions nut 17.It also is a holding screw that is installed in steel nail fixed axis 5 ends that the steel lock is decided device 14.Other structure is same as the previously described embodiments.After steel nail fixture 2 is first-class, can adjust the relative position of two-semiaxle by rotation double rotational directions nut 17, thereby it is involutory closely with fracture site to drive steel nail, screws back of the body medicated cap 18 then two-semiaxle is fixed.
