The reset of long skeleton screw or oblique fracture is more difficult, and conventional reduction forceps have two kinds at present：One kind is big towel Pincers, clamp fracture end both sides with the binding clip front end of big towel forceps when using and are resetted, in view of the binding clip tip of big towel forceps is in point-like Contacted with bone face, and reset limited strength, often result in that the reduction of the fracture is unstable or malreduction；Another is standard reset pincers, Standard reset pincers, which can typically be stablized, clamps the reseting fracture broken ends of fractured bone, but because of bone face after reseting fracture and the binding clip and caliper of reduction forceps Between narrow space, it is difficult to place steel plate and carry out ultimate fixation.

In summary, the two kinds of reduction forceps used at present all can not carry out being satisfied with reset to long skeleton screw or oblique fracture, And because operating difficulties causes operation time-consuming long, a series of recent and long term complication thus can be caused.These problems So far do not efficiently solved, being highly desirable to a kind of new reduction forceps of research, long bone is oblique or helical bone to adapt to reset The need for folding operation.

Utility model content

Problem to be solved in the utility model is to provide a kind of resetting long bone pincers, this reduction forceps can it is simple and quick, Safely and effectively oblique to long bone or spiral fracture carries out reattachment surgery, can shorten operating time, reduces in art, postoperative one is Row complication.

Solving the technical scheme of above-mentioned technical problem is：

A kind of resetting long bone pincers, it includes binding clip, caliper, and binding clip is made up of the relative clamp in left and right two, caliper connection The nut rotating device of control reduction forceps folding is installed on the rear portion of binding clip, caliper, its improvements is, the left and right two of binding clip Individual clamp is made up of two and half arc clamps respectively, and two and half arc clamps are connected along the length direction of caliper, and two and half Arc clamp is in same clamp plane, and the circular arc concave side of half arc clamp of two side bitting clamps is relative, the arc clamp of front end half Crooked radian be adapted with the flexibility of long bone side wall, the crooked radian of the arc clamp of front end half is less than the arc clamp of rear end half Crooked radian, the distance between the arc clamp of front end half of two side bitting clamps is less than the distance between arc clamp of rear end half.

There is band on above-mentioned resetting long bone pincers, the medial surface of the arc clamp of front end half of described two clamps, band is with before The long bone side wall for holding half arc clamp to clamp is relative.

Above-mentioned resetting long bone pincers, the length of the arc clamp of front end half of described two clamps is 20-40mm, and width is 5- 15mm, the length of the arc clamp of rear end half of two clamps is 40-60mm.

The beneficial effects of the utility model are：

Two clamps of binding clip of the present utility model are made up of two continuous half arc clamps respectively, after two clamps The crooked radian of half arc clamp is held to be more than the crooked radian of the arc clamp of front end half so that between long bone bone face and reduction forceps Space is significantly increased, and is greatly facilitated and is placed the operation that steel plate carries out ultimate fixation；The arc clamp of front end half of two clamps Crooked radian is adapted with the flexibility of long bone side wall, surface-to-surface contact is presented with bone face so that fixed effect is more stable, and half Arc clamp medial surface has band, increases the frictional force of clamping face and bone face, is difficult to slip during reset, resets and more stablize. The utility model is simple in construction, easy to use, substantially reduces the time for resetting long skeleton screw or oblique fracture, improves operation Efficiency, is worth of widely use.
