Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of orthopaedics proposed resets Pincers.

To achieve the goals above, the utility model adopts the technical scheme that

A kind of reduction forceps of bone is designed, the first clamp handle and the second clamp handle including the connection that intersects, first clamp handle It above and with the second clamp handle junction is rotatably equipped with pin shaft, the pin shaft is fixedly connected with the second clamp handle, first clamp handle one End is fixed with the first chela, and second clamp handle is fixed with two the second chelas, two institutes close to one end of the first chela It states the second chela to be bent to the first chela, and the first chela is bent to the second chela, second chela and the first chela top End is fixedly connected to fixed ball, and equidistant fixing sleeve is equipped with annulus outside second chela and the first chela, and described the One clamp handle other end side is fixed with arc fixed plate, and the arc fixed plate is arranged through the second clamp handle, and clamps with second Handle is slidably connected, and uniform close is equipped with location hole along its length on the arc fixed plate, and the positioning hole is equipped with spiral shell Line runs through and is threaded with positioning screw in second clamp handle, and the positioning screw is inserted into one of positioning hole.

Preferably, the annulus is rubber ring.

Preferably, one end and the first clamp handle far from the second chela of second clamp handle are all provided with far from one end of the first chela There is anti-slip layer.

The utility model proposes a kind of reduction forceps of bone, beneficial effect is: the first chela and two the second chela structures At three-jaw, it is capable of the rotation of significantly more efficient control bone block, the annulus being arranged outside the first chela and the second chela is capable of increasing The setting of frictional force between reduction forceps and bone block, arc fixed plate and positioning screw can replace manpower to control reduction forceps Opening angle.The utility model structure is simple, easy to use, and the stability of splenial bone is improved using three chelas, can be controlled The rotation of bone block in reseting procedure processed, additionally it is possible to allow reduction forceps to keep certain splenial bone angle, the labour for mitigating medical staff is strong Degree also improves the working efficiency of medical staff.

Detailed description of the invention

Fig. 1 be the utility model proposes a kind of reduction forceps of bone structural schematic diagram；

Fig. 2 be the utility model proposes a kind of reduction forceps of bone Fig. 1 in enlarged drawing at A.

In figure: the first clamp handle 1, the second clamp handle 2, pin shaft 3, the first chela 4, fixed ball 5, arc fixed plate 6, location hole 7, positioning screw 8, the second chela 9, annulus 10.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-2, a kind of reduction forceps of bone, the first clamp handle 1 and the second clamp handle 2 including the connection that intersects, first It is rotatably equipped with pin shaft 3 in clamp handle 1 and with 2 junction of the second clamp handle, pin shaft 3 is fixedly connected with the second clamp handle 2, the first clamp handle 1 One end is fixed with the first chela 4, and the second clamp handle 2 is fixed with two the second chelas 9 close to one end of the first chela 4, and two Second chela 9 is bent to the first chela 4, and the first chela 4 is bent to the second chela 9, and three chelas improve the steady of splenial bone It is qualitative, the rotation of bone block can be controlled, the second chela 9 and 4 top of the first chela are fixedly connected to fixed ball 5, the second pincers Equidistant fixing sleeve is equipped with annulus 10 outside pawl 9 and the first chela 4, and annulus 10 is rubber ring, the second clamp handle 2 and the first clamp handle 1 Bottom end be equipped with anti-slip layer, the annulus 10 of rubber material can either increase the frictional force of reduction forceps and bone block, and can reduce The bottom end of injury to people's soft tissue, the second clamp handle 2 and the first clamp handle 1 is equipped with anti-slip layer, and anti-slip layer can allow medical staff More firm holds reduction forceps.
