Abstract

The utility model relates to a surgical medical instrument, in particular to a bone-rolling instrument for orthopaedics operations. The utility model consists of two detachable tong handles hinged together with a camber jaw through its plug-connected hinges in the front end of the detachable tong handles and an elastic traction sheet which can get through the guide rail slot provided on the inner side wall of the camber jaw. The back of the two tong handles are faced the back of the outside of the camber jaw. The guide rail slot providing on the inner side wall of the two tong handles is a through slot perforating lengthways the chamber jaw segment. One end of the elastic traction sheet is equipped with a hang-and-pull device which can hang and pull wires, threads or fretsaws. By using the utility model, the orthopaedics operations of bone-rolling leading wires or steel leading wires, and introducing bone-cutting fretsaws become easy and sample, which can not damage blood vessels, nerves, muscles, tendons and other organs. And the wound surface of the cut in operations is smaller.

Description

Bone surgery is used around bone object

Technical field

This utility model relates to the surgical operation medical apparatus and instruments, be specifically related to that a kind of bone surgery uses around the bone object tool.

Background technology

In the clinical whole osseous surgery of orthopaedics, often need to carry out around the bone lead-in wire, draw steel wire or introduce deep scroll saw operation, be to operate at present with right angle forceps, because right angle forceps does not have curvature, can not be close to periosteum in the operation, causes tissue injurys such as blood vessel, nerve, muscle, tendon easily; And make operative incision open greatlyyer, not easy to operate.

Summary of the invention

The purpose of this utility model is to provide a kind of bone surgery to use around bone object, in the clinical whole osseous surgery of orthopaedics, adopt this around bone object, make around the bone lead-in wire, draw steel wire or introduce deep scroll saw operation and become simple, to overcome the above-mentioned defective that this operation technique instrument at present exists.

This utility model bone surgery is used around bone object, comprise that two are hinged to split type pincers handle and elastic traction sheet that can pass of arc vice jaw only by the plug-in type hinge of its front end from the guide-track groove on two pincers handle arc vice jaw medial walls, the rear portion of described two pincers handles is to arc vice jaw outside back, guide-track groove on described two pincers handle medial walls is the groove that vertically connects its arc vice jaw section, and an end of described elastic traction sheet is provided with can wear the extension machine drawing structure of hanging silk, line or scroll saw.

The plug-in type hinges of described two pincers handle front ends are that the shoulder that plugged together mutually by through hole of leaving at the front slideway trench bottom of a pincers handle and the through hole with preceding pincers handle that stretches out in its guide-track groove bottom of front end edge of another pincers handle is prominent to be constituted.

This utility model bone surgery uses the using method around bone object to be, arc vice jaw with a said pincers handle inserts from operative incision earlier, being close to subperiosteum along skeleton one side inserts, the arc vice jaw that another is clamped handle inserts from operative incision again, being close to subperiosteum along the skeleton opposite side inserts, and the shoulder that makes two pincers handle arc vice jaw front ends is prominent and through hole plugs together hinged, then make the arc vice jaw of two pincers handles be surrounded on the skeleton periphery, front end with said elastic traction sheet penetrates from the guide-track groove on the pincers handle arc vice jaw of a side again, until the guide-track groove from the handle arc vice jaw of opposite side, pass, can will wear the silk that hangs on the elastic traction sheet other end extension machine drawing structure, line or scroll saw are pulled in the guide-track groove on the pincers handle arc vice jaw that is surrounded on the skeleton periphery.

Adopt this utility model around bone object, make in the bone surgery around the bone lead-in wire, draw steel wire or introduce deep scroll saw operation and become simple, can not cause tissue injurys such as blood vessel, nerve, muscle, tendon; And the operative incision wound face is less.

Description of drawings

Fig. 1 is the overall structure sketch map of bone surgery around bone object;

Vertical view when Fig. 2 is two pincers handle (1,2) split states shown in Fig. 1;

The specific embodiment

Below the embodiment that provides with regard to accompanying drawing this utility model structure is described in further detail.

With reference to Fig. 1,2, a kind of bone surgery is used around bone object, comprise that two are hinged to 1,2 and elastic traction sheets 4 that can pass of split type pincers handle of arc vice jaw only by the plug-in type hinge of its front end from the guide-track groove 11,21 on two pincers handle 1,2 arc vice jaw medial walls, the rear portion of described two pincers handles is to arc vice jaw outside back, guide-track grooves the 11, the 21st on described two pincers handle medial walls vertically connect the groove of its arc vice jaw section, and an end of described elastic traction sheet 4 is provided with can wear the extension machine drawing structure of hanging silk, line or scroll saw.

With reference to Fig. 2, the plug-in type hinge of described two pincers handle 1,2 front ends is to be made of with the shoulder prominent 22 that the through hole 12 with preceding pincers handle 1 that stretches out in its guide-track groove 21 bottoms of front end edge of another pincers handle 2 plugs together mutually the through hole of leaving in front slideway groove 11 bottoms of a pincers handle 1 12.

With reference to Fig. 1, the extension machine drawing structure on described elastic traction sheet 4 one ends is a barb 41, or hole (not providing diagram in addition).

The rear portion pommel of described two pincers handles 1,2 is embedded with handle 3.

In order in operation technique, to make the plug-in type hinge of two pincers handle front ends be easy to plug together, the first half of a pincers handle 1 in described two pincers handles is made for nearly semicircular arc jaw, the first half of another pincers handle 2 is made for the ellipse arc jaw (this view omit, do not add give unnecessary details) of radius of curvature greater than the former arc curvature radius.
