In the utility model, fixing material is parallel to the surface of a femoral neck, the bone nail guiding limitator always goes deep into the femoral neck and can not penetrate out of the surface of the femoral neck, the fixing effect is good, the structure is simple, the cost is low, and the use is simple.
Description
Technical field
This utility model relates to a kind of stopping means, relates in particular to nail guide and limit device.
Background technology
Fracture of femoral neck is common fracture phenomenon, and the fracture back takes place is difficult for healing, tends to follow other pathological changes, in time, effectively, safety, internal fixation can reduce the generation of complication reliably.The material of implementing the fracture of femoral neck internal fixation is more, comprises hollow nail, mother and sons' nail etc., and hollow nail is more commonly used, and operating procedure be earlier with the guide pin location, and the back is with electric drill boring, after the punching with also fastening in the immobilization material load hole.But these operations all require the medical worker that higher operation level and state are preferably arranged, otherwise are easy to the hole is deflected, and cause immobilization material just can't not bring into play maximum effect, askew during as punching must be more, even punch bone surface, then must beat again.And the patent No. to be the fracture of femoral neck self-locking synthetism device of 200420044020.0 patent disclosure adopt main nail and auxilliary pin structure, though the drawback of having avoided immobilization material not have dress just causing, but the front end of auxilliary nail need be fixed on the main nail front end, and is more difficult in the operation.
The utility model content
This utility model provides a kind of simple to operate, effective nail guide and limit device for solving the prior art problem.
The technical solution of the utility model is: nail guide and limit device is characterized in that: comprise gag lever post, an end of gag lever post is provided with connecting rod, and the other end of connecting rod is equipped with position-limiting tube; Gag lever post is parallel with position-limiting tube.
During operation, the gag lever post of nail guide and limit device is affixed on bone surface along neck of femur, the inner of position-limiting tube peaks at the greater trochanter surface, endoporus by position-limiting tube pierces guide pin in neck of femur, after empirical tests is positioned at femur inside and correct position, hollow drill bit is inserted in guide pin boring, and reuse macaroni yarn tapered sleeve is gone into the guide pin tapping, and the immobilization material of choosing is screwed into neck of femur by guide pin; Because gag lever post is parallel with position-limiting tube, so in the operating process, punching is surperficial parallel with neck of femur all the time, can not produce the phenomenon that the hole is deflected, and is simple to operate, effective.
As preferably, described connecting rod is fixedly connected on the middle part of position-limiting tube.
As preferably, be provided with interior pipe in the described position-limiting tube, described interior pipe can slide in position-limiting tube.
As preferably, described gag lever post is scalable.
As preferably, described gag lever post is provided with size scale.
As preferably, the length of described gag lever post is 5～15cm, and cross-sectional diameter is 1.5～3mm.
As preferably, the spacing of the central shaft of described gag lever post and the central shaft of position-limiting tube is 0.8～1.5cm.
As preferably, described in the internal diameter of pipe be 2～7mm.
As preferably, the angle between gag lever post and the connecting rod is 90～150 degree.
As preferably, the connecting portion of gag lever post and connecting rod is rounded down.
In sum, the utlity model has following advantage:
1, immobilization material is parallel with the neck of femur surface, gos deep into neck of femur inside all the time, can not pass bone surface, good fixing effect;
2, this utility model is simple in structure, and is with low cost, uses simple.
