But, the rear portion of current bone holding forcep pincers arm after grasping fracture end owing to opening angle is inadequate, after causing application bone holding forcep that fracture site is resetted, Steel Plate For Fixation Of Fracture cannot insert the surface of fracture site, which results in sometimes use instead other apparatuses come reseting fracture position just can insert Steel Plate For Fixation Of Fracture to fracture site surface, so often cause the loss of the reduction of the fracture. And after Steel Plate For Fixation Of Fracture implantation, often need the auxiliary interim fixation bone fracture plate such as kirschner pin, as needed the words regulating Steel Plate For Fixation Of Fracture position, in addition it is also necessary to extracted by kirschner pin, squeezing into kirschner pin after redefining Steel Plate For Fixation Of Fracture position again, the operation of this kind of method is loaded down with trivial details, add operating time and the misery of patient.

Practical novel content

The purpose of this utility model is to solve the problems of the technologies described above, a kind of rongeur for fracture diaplasis is provided, Steel Plate For Fixation Of Fracture can not be directly inserted when not unclamping bone holding forcep, and put into after Steel Plate For Fixation Of Fracture cannot the problem of fixation bone fracture plate temporarily after solving current rongeur for fracture diaplasis reseting fracture.

The technical scheme that the utility model is taked is:

A kind of rongeur for fracture diaplasis, comprise the pincers arm, clamp handle and the pincers axle that arrange in pairs, described pincers arm and clamp handle are connected by described pincers axle and realize clamp to clamp axle rotation, end a clamp handle connects a clamp handle buckle teeth row, and the end in another clamp handle arranges card and buckles, when clamping arm clamp, described card buckles in a buckle teeth of described clamp handle tooth row, keep holding force, it is characterized in that, on the described pincers arm of the one or both sides of described pincers axle position, arrange recessed section.

Further, arranging fixing pole on the described pincers arm of one or both sides, described fixing pole is threaded connection on described pincers arm.

Further, described recessed section is recessed section of semiellipse arc shape.

Further, inside described pincers arm, row's chela is set.

The beneficial effects of the utility model are:

(1) groove clamped on arm adds the angle of both sides pincers arm rear openings, thus facilitates Steel Plate For Fixation Of Fracture to insert;
