Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-2, the utility model provides an orthopedic surgical instrument, including first action bars 1 and second action bars 2, first action bars 1 and second action bars 2 are articulated through activity hinge 4, fixedly connected with pincers handle 5 is distributed to first action bars 1 and 2 front ends of second action bars, the fixedly connected with guide pin hole 6 is gone up to pincers handle 5, the inboard fixedly connected with cardboard 7 of first action bars 1, the inboard fixedly connected with arc 8 of second action bars 2, cardboard 7 block is on 8 upper portions of arc, the equal fixedly connected with ring 3 in first action bars 1 and 2 rear ends of second action bars.

It should be noted that the first operating lever 1, the second operating lever 2, the living hinge 4 and the forceps handle 5 are connected with each other in the same manner as scissors, the guide pin holes 6 are fixedly connected with the forceps handle 5 to form an integrally formed structure, the guide pin holes 6 at the upper end of the forceps handle 5 are symmetrically distributed, and the inner diameter of the guide pin holes 6 satisfies the insertion of kirschner wires.

In the embodiment, the inner walls of the clamping plate 7 and the arc-shaped plate 8 are both provided with a scale rod 9.

Wherein, for guaranteeing the location to first action bars 1 and

second action bars
