Description

Arc combination pliers

Technical field

This utility model belongs to medical instruments field, more particularly, is related to make during oral and maxillofacial surgery repaiies reconstructive surgery The moulding plate clipping apparatus of reconstruction.

Background technology

During mandible reconstruction, need to rebuilding moulding plate quick shearing, existing clipping apparatus there are many defects. Synthes fast shut-offs clamp the fixed plate for shearing thickness 1.5-2.8, use in pairs, band file, but the instrumentation is loaded down with trivial details, Titanium plate of polishing is still needed to after cut-out.Synthes MatrixMANDIBLE excising forceps are used for 1.0-1.5 fixed plates, block pincers central authorities and lack Mouth is matched with fixed plate connecting portion, and so as to exercise positioning function, the excising forceps Formation cross-section still needs to polish smooth use, operation It is loaded down with trivial details.KLS Martin titanium plate cutting nippers can be used to shear blade plate, but there is no location structure, and in shear history, titanium plate is easy , easily there is titanium plate deformation in displacement.The multi-functional titanium plate cutting nippers of KLS Martin can be used for 1.0,1.5,2.0 Martin and rebuild Titanium plate is sheared and is bent, and there is whetstone side and polishes for edge, but the section is still more sharp keen, and after need to polishing, row is fixed again, It is cumbersome.

The content of the invention

The purpose of this utility model is to provide a kind of quick shearing to rebuild moulding plate, and forms circular arc, cuts without corner angle The arc combination pliers of section.

To realize object above, this utility model discloses technical scheme below：Arc combination pliers, including cut off the main foot of foot, Foot pair foot, alignment pin and cover plate are cut off, the main foot head of foot of cutting off arranges a circular groove, and one group of bottom portion of groove setting is convex The arc orbit for going out, the arc orbit of the protrusion arrange a cavity, and cavity one end is the circular arc edge of a knife of protrusion, the cavity other end Alignment pin is set, and with the circular arc edge of a knife center of circle protruded on a horizontal plane, the foot pair foot head of cutting off is in circular arc to alignment pin Shape, the foot pair foot head of cutting off be able to insert the circular groove for cutting off the main foot head of foot, cut off foot pair foot head and arrange one The recessed arc orbit of group, the arc orbit of the female be able to be fitted with the arc orbit of the protrusion, the circle of the female Arc track arranges a cavity, and cavity one end is the recessed circular arc edge of a knife, the circular arc edge of a knife of the female and the circular arc of the protrusion The edge of a knife is fitted.

Used as a preferred version, the alignment pin is arranged in positioning pedestal, and the arc orbit of the protrusion arranges one Breach so that positioning pedestal be able to be inserted breach and fix.

It is as a preferred version, described to cut off the main foot of foot and cut off foot pair foot handgrip part setting concave surface.

As a preferred version, and the arc orbit and recessed arc orbit of the position of cover plate upper plenum and protrusion The position correspondence of upper plenum.

The utility model has the advantage of：By common shearing by circular motion completing, using cutting off the main foot head of foot Portion's circular groove and bottom portion of groove protrusion arc orbit, with cut off foot pair foot circular arc head and recessed arc orbit match somebody with somebody Close and produce circular motion, rotation is produced not against Traditional center axle center so that core need not punch to ensure circular arc knife Enough active forces of mouth and alignment pin, and titanium plate arc surface is controlled using alignment pin, titanium plate nail is inserted into alignment pin Realize that titanium plate is positioned, direct shearing is to the circular arc truncation surface with nail as the center of circle, it is to avoid sharp corners pass the wind of skin Danger, while the troublesome operation of roughness profile of being polished in reducing art repeatedly.
