Abstract
The invention provides a metal wire shear, which is composed of a shear blade region, a joint region and a gripping region, wherein the gripping region is composed of a thumb hole, a finger pulp pressure rod, a rubber part, an expansion region, a force absorption seat and a third finger hole; the side face of the shear blade region is bent in an arc shape and bent sizes and positions are symmetrical; a shear blade is formed by inclining and defecting and the thickness of the outer side of the shear blade is more than that of the shear blade; a buffering belt is a part which is lack of a shear body after the shear blade is designed to be of a horizontal shape and the length of the buffering belt is more than that of the shear blade. Only one joint stagger groove of the joint region is located in a near gripping region and the joint stagger groove and a central line of the front side of the shear body are crossed to form an angle of 45 DEG; a joint central shaft is located in a joint central hole of a joint central area and the bottom of the joint stagger groove of the joint region is connected with the shear blade part. The thumb hole and the third finger hole are located at the outer side of the central line of the shear body and the finger pulp pressure rod is located in a far joint region of the thumb hole. A free end of the far joint region of the finger pulp pressure rod is of a bent shape; the thumb hole is of a front-side horizontal shape which is vertical to the shear body and a 'cross shape' is formed on the side face by the thumb hole and the shear body rubber.
Description
Affiliated field:
Be the use apparatus of cutting off for ligature or arch wire in balance fixed orthodontic in mouth cavity orthodontic field, also can be used for the shearing of correction guide plate.
background technology:
Conventionally clinically, the arch wire end that only has that cuts off unnecessary arch wire for arch wire end clamps, when in use, due to the length of caliper, some is short relatively, conventionally in direct-view very not operation smoothly wild in the situation that, use more not smoothly cutting off aspect ligature, cut off ligature conventional be crown scissors, this cuts and cuts in use ligature and be easy to, but cuts the free but very difficult of arch wire end.Conventionally cannot fix free arch wire, easily cause arch wire to move on cutting edge and can not cut off smoothly, simultaneously the length of crown scissors also exists too short and is difficult for the factor of touching, increase and correct the individual difficulty coordinating, strengthen and correct individual cooperate degree simultaneously, the flow operations of correction is often formed to unfavorable factor.
summary of the invention:
According to the lever principle of physics and clinical instructions for use, with clinical operation technique, for instructing thinking, the position characteristics during according to orthodontic procedure is determined form and the size of wire scissors.The total length of wire scissors is 160 millimeters, and wire scissors is to be made up of cutting edge district, hinge area and grip zone, and there are thumbhole, abdominal pressure bar, rubber section, stretching area in grip zone, subtract power seat and unnamed foramina formation.The side form in cutting edge district is arc-shaped bend, bending body size, the position symmetry of cutting, it is circular that positive form is point, cutting edge is damaged formation that tilt, the thickness as outside of cutting edge is greater than the thickness of cutting edge, buffer strip is the part that cutting edge is designed to cut after horizontal body disappearance, and the length of buffer strip is greater than the length of cutting edge; The overall length in cutting edge district is 25 millimeters, and length positive after bending forming is 20 millimeters, and the width of nearly hinge area, cutting edge district is 10 millimeters, and the gross thickness of nearly hinge area, cutting edge district is 8 millimeters; The thickness of cutting point outside is 1 millimeter, the thickness of nearly hinge area, cutting edge district is straight line evolution process to the thickness of cutting point outside, edgewise bend cutting edge form, the damaged form of inclination of cutting edge is sharp shape of triangle, the direction tilting is from lateral offside, the thickness that is cutting edge portion disappearance is the thickest, and the thickness of cutting edge is identical.Be skewed at the blade of cutting edge, that the secondary that blade forms again on the basis of cutting edge inclination tilts, blade thickness after inclination is 1 millimeter, after front is shaped, the length of cutting edge is 18 millimeters, the length of buffer strip is 2 millimeters, and the width of buffer strip is wide and the narrow of point and nearly hinge area cut in two in the middle of being.Hinge area is between cutting edge district and grip zone, and the length of hinge area is 20 millimeters, and wide is 10 millimeters, thickness is 8 millimeters, the degree of depth of the staggered ditch in joint is 4 millimeters, and the staggered ditch in joint of hinge area only has one to be in nearly grip zone, the staggered ditch in joint and cut body front center line and intersect for miter angle.Articulation center axle is at the articulation center at center, hinge area, and the bottom of the staggered ditch in the joint of hinge area is connected with cutting edge portion, is but not parallel.The diameter in articulation center hole is 3.5 millimeters, cutting body with another is the axis hole of articulation center axle with respect to the position in articulation center hole, the longest air line distance of axis hole is less than the diameter in articulation center hole, articulation center axle and cut accordingly body and be connected to a fixed, articulation center axle utilizes another to cut falling on body and recessedly completes two merging of cutting body by articulation center axle, forms wire scissors.The length of grip zone is the longest region of wire scissors, and the length of grip zone is 115 millimeters, and the width of nearly hinge area, two grip zones is respectively 5 millimeters, thickness is respectively 8 millimeters, and to subtracting power seat part, its width is respectively 5 millimeters, thickness is respectively 5 millimeters, and the outer rim of grip zone is smooth class semiellipse form; The thumbhole of grip zone, abdominal pressure bar and rubber section are cut on body at one, and stretching area, subtract power seat and unnamed foramina is cut on body at another, rubber section is corresponding with the position that subtracts power seat, and thumbhole and unnamed foramina are being cut the outside of body center line, and abdominal pressure bar is in the hinge area far away of thumbhole, the free-end of abdominal pressure bar is bending, bending direction be towards unnamed foramina, the form of thumbhole perpendicular to the positive level of cutting body to, at side thumbhole with cut crossing " ten " word shape that is of body.The frontal width of abdominal pressure bar is 5 millimeters, and the thickness of abdominal pressure bar is 5 millimeters, and abdominal pressure bar section length is 70 millimeters; The form of rubber section is the semicircle bodily form, and its diameter is 5 centimetres, and subtracting power seat is foursquare projection, and the height of projection is 0.5 millimeter, and the foursquare length of side is 5 millimeters, and subtracting power seat is 10 millimeters apart from the length of unnamed foramina.Thumbhole be shaped as ellipse, the cross section of hole body is half elliptic, the width in cross section is 5 millimeters, depth of section is 3 millimeters; The long straight line internal diameter of interior Kongzui of thumbhole is 28 millimeters, and in short lines, path length is 23 millimeters, and the hinge area far away hole body of thumbhole is 20 millimeters apart from rubber section distance; The shape of unnamed foramina is also oval, the cross section of hole body is half elliptic, the width in cross section is 5 millimeters, the height in cross section is 3 millimeters, the long straight line internal diameter of interior Kongzui of unnamed foramina is 28 millimeters, short lines internal diameter is 23 millimeters, the nearly hinge area of unnamed foramina, hole body and to subtract distance between power seat be 10 millimeters.Thumbhole and unnamed foramina shape are identical with size, and thumbhole and unnamed foramina are to cut position on body different with the angle relative from cutting body.The rubber section of wire scissors is high-elastic rubber, cuts body and all manufactures and form with medical steel.
Accompanying drawing and accompanying drawing explanation:
