Technical field

This utility model relates to a kind of Kirschner wire folding forceps, belongs to medical instruments field.

Background technology

Kirschner wire folding forceps, as a kind of medical apparatus and instruments of basis, is widely used in the operation of bone surgery, and in actual operation operation, it is used to bending and exposes Kirschner wire outside bone, prevents sharp-pointed tail end damage surrounding soft tissue.

In Fracture internal fixaiion operation, Kirschner wire is that bone surgery provides great convenience as conventional auxiliary reset fixed apparatus, but in operation, there is defect such as damage surrounding soft tissue and displacement etc., need a kind of apparatus by the Kirschner wire bending exposed to address this problem and be embedded in subcutaneous.Present most of doctor selects to clamp Kirschner wire with common cutting pliers and to exert oneself bending, and this mode is not only time-consuming but also require great effort, and also likely causes other tissue injury.

Utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can simplify operation technique, improve operation safety, reduce complication and produce and time saving and energy saving Kirschner wire folding forceps.

Kirschner wire folding forceps described in the utility model, comprise left clamp handle, right clamp handle, bending bar and slip fixture block, the side right clamp handle deviating from left clamp handle has slip fixture block groove, slip fixture block is arranged in slip fixture block groove, the top of left clamp handle by two bearing pins respectively with right clamp handle, slip fixture block is hinged, Kirschner wire placement space is left between slip fixture block upper end and slip fixture block groove, bending bar by rotating shaft and right clamp handle hinged, bending bar top is corresponding with the position of the Kirschner wire placement space of slip fixture block upper end, bending bar is perpendicular to a left side, the plane that right clamp handle is formed does gyration.

The use procedure of this Kirschner wire folding forceps is as follows:

First Kirschner wire is placed in the Kirschner wire placement space that right clamp handle is slided between fixture block and slip fixture block groove, now Kirschner wire treat that bending end is positioned on bending bar, closed clamp handle afterwards, left clamp handle drives slip fixture block to move upward by bearing pin, until block Kirschner wire, then rotate bending bar, bending bar is rotated around rotating shaft, Kirschner wire rotates along with bending bar and bends, and bending angle freely can be determined with operator.

Preferably, described slip fixture block top has contrate.After vising Kirschner wire, can prevent Kirschner wire from skidding by contrate.

Preferably, bending bar top arranges limited impression, carries out spacing by limited impression to Kirschner wire, can prevent Kirschner wire in Forging Process from swinging, guarantee normally carrying out of flexing movement.

Preferably, described left clamp handle and the pincers of right clamp handle are respectively fixed with one to the leaf spring clamped internal bend upper, and two leaf springs link together in its end.In order to prevent leaf spring from rotating, adopt following preferred version, that is: at least one leaf spring afterbody buckle and snap in pincers handle corresponding to this leaf spring by hook.

The beneficial effect that this utility model is compared with prior art had is:

This Kirschner wire folding forceps reasonable in design, the quick bending of Kirschner wire can be realized by this folding forceps, simple and convenient and its hetero-organization can not be damaged, improve operation safety, decrease complication to produce, and bending angle is controlled, time saving and energy saving, well reach requirements of operation, enable doctor complete operation better.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

As shown in Fig. 1 ~ 9, this Kirschner wire folding forceps comprises left clamp handle 1, right clamp handle 7, bending bar 2 and slip fixture block 6, the side right clamp handle 7 deviating from left clamp handle 1 has slip fixture block groove 11, slip fixture block 6 is arranged in slip fixture block groove 11, the top of left clamp handle 1 by two bearing pins 3 respectively with right clamp handle 7, slip fixture block 6 is hinged, Kirschner wire placement space 5 is left between slip fixture block 6 upper end and slip fixture block groove 11, bending bar 2 is hinged by rotating shaft 4 (adopting branchia shaft screw in the present embodiment) and right clamp handle 7, bending bar 2 top (upper surface of the bending bar 2 namely contacted with Kirschner wire) is corresponding with the position of the Kirschner wire placement space 5 of slip fixture block 6 upper end, bending bar 2 is perpendicular to a left side, the plane that right clamp handle is formed does gyration.

Wherein: slip fixture block 6 top has contrate 13, can prevent Kirschner wire from skidding after vising Kirschner wire; Bending bar 2 top arranges limited impression 10, carries out spacing to Kirschner wire, prevents Kirschner wire in Forging Process from swinging; Left clamp handle 1 is respectively fixed with one to the leaf spring 8 clamped internal bend by button-headed screw 9 with the pincers of right clamp handle 7 upper, two leaf springs 8 link together in its end, rotate for preventing leaf spring 8, in the present embodiment, a hook 12 is set at leaf spring 8 afterbody of left clamp handle 1, and snaps in the pincers handle of left clamp handle 1 by above-mentioned hook 12.

The use procedure of this Kirschner wire folding forceps is as follows:

First Kirschner wire is placed in the Kirschner wire placement space 5 that right clamp handle 7 is slided between fixture block 6 and slip fixture block groove 11, now Kirschner wire treat that bending end is positioned on bending bar 2, closed clamp handle afterwards, left clamp handle 1 drives slip fixture block 6 to move upward by bearing pin 3, until block Kirschner wire, then rotates bending bar 2, bending bar 2 is rotated around rotating shaft 4, Kirschner wire is stuck in limited impression 10 place of bending bar 2, and rotate along with bending bar 2 and bend, bending angle freely can be determined with operator.

Except above-mentioned points, one slope 14 can also be set on right clamp handle 7 top, limit the rotational angle of bending bar 2, when Kirschner wire bending is to this 14 position, slope of right clamp handle 7, bending bar 2 rotates and stops, thus can limit the flexible minimum angles of Kirschner wire (in the present embodiment, the flexible minimum angles of Kirschner wire is 35 °).

From the above, this Kirschner wire folding forceps reasonable in design, the quick bending of Kirschner wire can be realized by this folding forceps, simple and convenient and its hetero-organization can not be damaged, improve operation safety, decrease complication and produce, and bending angle is controlled, time saving and energy saving, well reach requirements of operation, enable doctor complete operation better.
