Abstract
An instrument for use in cartilage removal comprises an elongate body having a first end and a longitudinal axis having a longitudinal direction. A cartilage removal portion is coupled to the elongate body at the first end. The cartilage removal portion includes a plurality of serrated blades substantially perpendicular to the longitudinal axis and adapted for removing material while moving in the longitudinal direction. Each serrated blade has a centroid located along the longitudinal axis.
Claims23
An instrument for use in cartilage removal, the instrument comprising:
- an elongate body having a first end and a longitudinal axis having a longitudinal direction;
- and,
- a cartilage removal portion coupled to the elongate body at the first end, the cartilage removal portion including a plurality of serrated blades substantially perpendicular to the longitudinal axis and adapted for removing material while moving in the longitudinal direction, each serrated blade having a centroid thereof located along the longitudinal axis.
A method for cartilage removal, comprising:
- contacting a cartilage of a patient with a cartilage removal portion of a tool, the cartilage removal portion having a first end, a second end, and a longitudinal axis extending therebetween, the cartilage removal portion including one or more elongate members disposed radially outward from the longitudinal axis, wherein the one or more elongate members extend parallel to the longitudinal axis from the first end to the second end;
- and
- causing the elongate body to rotate around the longitudinal axis or reciprocate, so that the one or more elongate extensions cut or abrade the cartilage.
A method for cartilage removal, comprising:
- contacting a cartilage of a patient with a grater, the grater having a shank attached to a plate, the plate having a first face and a second face opposite the first face, the plate defining one or more holes extending therethrough from the first face to the second face, each hole defined by a respective cutting edge of the plate;
- and
- reciprocating the plate so that the respective cutting edge defining one or more of the holes cuts or abrades the cartilage.
A method for cartilage removal, comprising:
- contacting a cartilage of a patient with a cartilage removal tool having a central longitudinal axis, and at least one rotatable helical strip arranged around the longitudinal axis, the helical strip separated radially from the longitudinal axis by a space;
- and,
- rotating the at least one helical strip so that the at least one helical strip revolves around the longitudinal axis and cuts or abrades the cartilage.
A cartilage removal tool, comprising:
- a handle having a longitudinal axis and a distal end;
- and
- a cartilage removal portion at the distal end of the handle, the cartilage removal portion having a curved plate with a plurality of serrated blades thereon, each serrated blade substantially perpendicular to a major surface of the curved plate, each serrated blade having a plurality of teeth substantially perpendicular to the major surface, each serrated blade adapted for removing material.
A method of removing cartilage, comprising:
- contacting a cartilage with a tool comprising a handle having a longitudinal axis and a trapezoidal tube at an end of the handle, the trapezoidal tube having inner walls defining an opening therethrough, the opening having an axis substantially parallel to the longitudinal axis of the handle, the trapezoidal tube having at least one cutting edge;
- and
- moving the tool, so as to cut or grind the cartilage.
