Distal end cutter
View Patent ↗A flush cutter of wires located on a patient's teeth has at least one pivotably carried cutting edge. An outer surface of the edge can be positioned adjacent to a surface from which the wire protrudes. An elastic insert or clamp, for griping cut wire ends, is carried adjacent to the edge. The insert has first and second spaced apart ends. A rigid surface is located to pivot toward the edge. The elastic clamp extends, in part, to the inner surface of the edge. As the cutting edge moves toward the rigid surface to cut the wire, the elastic clamp grips the cutoff wire end for removal. The rigid surface can be formed as a second cutting edge that moves toward the one cutting edge.
1. A dental instrument for cutting and holding a wire end extending from a surface comprising:
first and second opposed cutting edges movable relative to one another and oriented so as to be positionable against a surface from which a wire end extends;
a separate, substantially linear, elongated elastomeric member with a gripping surface wherein the member is positioned with at least a region of the gripping surface located adjacent to one of the edges whereby as the edges move together the gripping surface of the member moves adjacent to and substantially abuts a metal part adjacent to the other edge.
2. An instrument as in claim 1 where the metal part includes a metal clamping surface, adjacent to the other edge, toward which the gripping surface moves as the cutting edges move toward one another.
3. An instrument as in claim 1 which includes first and second pivotably coupled jaws with one cutting edge carried on a respective jaw and wherein the region of the gripping surface is elongated and relatively planar.
4. An instrument as in claim 3 wherein the elastomeric member is carried in an interior recess formed on one jaw.
5. An instrument as in claim 4 wherein the other jaw carries a clamping surface toward which the planar gripping surface moves as the jaws move toward one another.
6. An instrument as in claim 5 which includes, in one of the jaws, a recess for receipt of an engaging part of the elastomeric member.
7. An instrument as in claim 3 which includes, in one of the jaws, a recess, bounded on at least three sides, for receipt of an engaging part of the elastomeric member.
8. An instrument as in claim 1 which includes,
an extension portion with a recess for receipt of an engaging part of the elastomeric member.
9. An instrument as in claim 8 wherein the recess has a first, elongated dimension that extends from the gripping surface and has a variable width.
10. An instrument as in claim 1 where the elastomeric member is positioned in a multi-sided slot with an interference fit.
11. An instrument as in claim 1 where the elastomeric member includes at least one integrally formed insertion tab.
12. A dental instrument for cutting and holding a wire end extending from a surface comprising:
first and second opposed cutting edges movable relative to one another and oriented so as to be positionable against a surface from which a wire end extends;
an elongated elastomeric member with a substantially flat gripping surface where the member is positioned with at least a region of the gripping surface located adjacent to one of the edges whereby as the edges move together the region of the surface of the member moves adjacent to and substantially abuts at least part of the other edge, which includes, an extension portion with a recess for receipt of an engaging part of the elastomeric member where the recess has a first, elongated dimension that extends from the gripping surface and has a variable width wherein the variable width has second and third different dimensions to facilitate locking the elastomeric member in the recess.
13. A dental instrument for cutting and holding a wire end extending from a surface comprising:
first and second opposed cutting edges movable relative to one another and oriented so as to be positionable against a surface from which a wire end extends;
an elongated elastomeric member with a gripping surface where the member is positioned with at least a region of the gripping surface located adjacent to one of the edges whereby as the edges move together the region of the surface of the member moves adjacent to and substantially abuts at least part of the other edge, which includes first and second pivotably coupled jaws with one cutting edge carried on a respective jaw and where the region of the gripping surface is elongated and relatively planar, which includes, in one of the jaws, a recess, bounded on at least three sides, for receipt of an engaging part of the elastomeric member and where the elastomeric member is located substantially within the recess except for the gripping surface which extends therefrom.
14. A dental instrument for cutting and holding a wire end extending from a surface comprising:
first and second opposed cutting edges movable relative to one another and oriented so as to be positionable against a surface from which a wire end extends;
an elongated elastomeric member with a gripping surface where the member is positioned with at least a region of the gripping surface located adjacent to one of the edges whereby as the edges move together the region of the surface of the member moves adjacent to and substantially abuts at least part of the other edge, which includes a recess for receipt of an engaging part of the elastomeric member, the recess includes at least first and second non-parallel planar surfaces wherein the elastomeric member is received in the recess with a press-fit and wherein the member presents a relatively flat gripping surface adjacent to the one edge.
15. An instrument as in claim 14 wherein the elastomeric member is located substantially within the recess except for the flat gripping surface.
16. An instrument as in claim 15 wherein the flat gripping surface is substantially rectangular.
17. A dental instrument for cutting and holding a wire end extending from a surface comprising:
a flush cutting edge movable relative to an opposed rigid surface and oriented so as to be positionable against a surface from which a wire end extends;
an elastomeric member with a substantially flat gripping surface wherein the member is positioned with at least a region of the flat gripping surface located adjacent to one of the edge or the opposed surface, whereby as the edge moves toward the opposed surface, the region of the flat surface also moves, the elastomeric member is received in a recess with a press-fit and presents a relatively flat gripping surface adjacent to the one of the edge or the opposed surface.
18. An instrument as in claim 17 wherein the elastomeric member is located substantially within the recess except for the flat gripping surface.
19. An instrument as in claim 18 wherein the flat gripping surface is one of substantially rectangular or substantially triangular.
20. An orthodontic cutter comprising:
at least one flush cutting edge;
an interior recess formed adjacent to the edge; and
a removable and replaceable, deformable, substantially linear, wire clamping member substantially carried in the recess, the member having first and second displaced ends, the ends having substantially the same cross section.
21. A cutter as in claim 20 wherein the recess is elongated with a closed end and a displaced open end.
22. A cutter as in claim 21 wherein the recess has a variable width parameter.
23. A cutter as in claim 20 which includes a second flush cutting edge in opposed relation to the flush cutting edge wherein the edges are arranged, relative to the deformable member so that both edges and the deformable member, at least in part, substantially abut one another in the absence of any wire gripped by the clamping member.
24. An orthodontic cutter comprising:
at least one flush cutting edge;
an interior recess formed adjacent to the edge; and
a deformable wire clamping member substantially carried in the recess, with a friction fit, the deformable member having first and second free ends wherein each end carries an insertion tab.
