Rebuild moulding plate clipping apparatus.
Background technology
During mandible reconstruction, need to rebuilding moulding plate quick shearing, existing clipping apparatus there are many defects.
The quick excising forceps of Synthes are used for the fixed plate of shearing thickness 1.5-2.8, use in pairs, band file, but the instrumentation is cumbersome,
Polishing titanium plate is still needed to after cut-out.Synthes MatrixMANDIBLE excising forceps are used for 1.0-1.5 fixed plates, block pincers center and lack
Mouth matches with fixed plate connecting portion, and so as to exercise positioning function, which still needs to polish smooth use, operation
It is cumbersome.KLS Martin titanium plates cutting nipper can be used for shearing bone plate, but location structure is not present, and titanium plate is easy in shear history
Titanium plate deformation easily occurs for displacement.The Martin that the multi-functional titanium plate cutting nippers of KLS Martin can be used for 1.0,1.5,2.0 is rebuild
Titanium plate is sheared and is bent, and side has whetstone to polish for edge, but the section is still more sharp keen, and row is fixed again after need to polishing,
It is cumbersome.
Invention content
The purpose of the present invention is to provide a kind of quick shearings to rebuild moulding plate, and formed it is arc-shaped, without corner angle truncation surface
Arc combination pliers.
In order to achieve the above object, the present invention discloses following technical scheme：Arc combination pliers, including cutting the main foot of foot, cutting
Foot pair foot, positioning pin and cover board, the main foot head of cutting foot set a circular groove, bottom portion of groove one group of protrusion of setting
Arc orbit, the arc orbit of the protrusion set a cavity, and cavity one end is the circular arc edge of a knife of protrusion, and the cavity other end is set
The circular arc edge of a knife center of circle of positioning pin, positioning pin and protrusion is on a horizontal plane, and the cutting foot pair foot head is arc-shaped, institute
The circular groove for cutting the main foot head of foot be able to be placed in by stating cutting foot pair foot head, and it is recessed to cut one group of foot pair foot head setting
Arc orbit, the arc orbit of the female be able to be bonded with the arc orbit of the protrusion, the arc orbit of the female
One cavity is set, and cavity one end is the recessed circular arc edge of a knife, and the circular arc edge of a knife of the female is pasted with the circular arc edge of a knife of the protrusion
It closes.
As a preferred embodiment, the positioning pin is arranged in positioning pedestal, the arc orbit setting one of the protrusion
Notch so that positioning pedestal be able to be inserted into notch and fix.
As a preferred embodiment, the cutting main foot of foot and cutting foot pair foot handgrip part setting concave surface.
As a preferred embodiment, and arc orbit and recessed arc orbit of the position of cover board upper plenum with protrusion
The position of upper plenum corresponds to.
The advantage of the invention is that：Common shearing by circular motion is completed, is justified using the main foot head of foot is cut
The arc orbit of arc groove and bottom portion of groove protrusion is produced with cutting the arc-shaped head of foot pair foot and the cooperation of recessed arc orbit
Raw circular motion generates rotation not against Traditional center axle center so that central part do not need to punching with ensure the circular arc edge of a knife and
Enough active forces of positioning pin, and titanium plate arc surface is controlled using positioning pin, titanium plate nail hole insertion positioning pin can be realized
Titanium plate positions, and direct shearing avoids the risk that sharp corners are pierced by skin, together to the arc-shaped truncation surface using nail hole as the center of circle
When reduce the troublesome operation of roughness profile of polishing repeatedly in art.

Specific embodiment
With reference to specific embodiment, the present invention is further explained.Experimental method used in following embodiments for example without
Specified otherwise is conventional method.The materials, reagents and the like used in the following examples, unless otherwise specified, can be from business way
Diameter obtains.It should be understood that these embodiments are only illustrative of the invention and is not intended to limit the scope of the invention.
Embodiment
Arc combination pliers include cutting the main foot 1 of foot, cut foot pair foot 2, positioning pin 3 and cover board 4.Fig. 1 is referred to, Fig. 1 is
Cut the main foot schematic diagram of foot.It cuts main 1 head of foot of foot and one circular groove 11 is set, bottom portion of groove sets the circular arc of one group of protrusion
Track 12, the arc orbit 12 of protrusion set a cavity 13, and 13 one end of cavity be the circular arc edge of a knife 14 protruded, 13 other end of cavity
14 center of circle of the circular arc edge of a knife of setting positioning pin 3, positioning pin 3 and protrusion is on a horizontal plane.
Fig. 2 is referred to, Fig. 2 is cuts foot pair foot schematic diagram.It cuts foot pair foot 2 and arc-shaped head 21 is set, cut foot pair
Foot head be able to be placed in the circular groove 11 for cutting main 1 head of foot of foot, cut 2 head of foot pair foot and set one group of recessed circular arc
