Abstract

The tip sharpener is a sharpening tool for the tips of instruments, such as the tips of ultrasonic scalers, as a non-limiting example. The tip sharpener includes a body with opposed first and second ends, and with a conical recess formed within the body such that a vertex of the conical recess is closer to the first end than to the second end. A mouth of the conical recess is opposed to the vertex of the conical recess and is formed in the second end of the body. At least one radially extending vent is formed in an outer surface of the body and is in open communication with the conical recess. The conical recess is adapted for receiving a tip of an instrument to be sharpened therein. In use, the tip is inserted with respect to the conical recess to a desired depth and rotated within the conical recess.

Dependent claims

A tip sharpener, comprising a body having opposed first and second ends, the body having a conical recess formed therein, the conical recess having a vertex closer to the first end than to the second end of the body and a mouth opposed to the vertex,

wherein the mouth of the conical recess is formed in the second end of the body,
wherein at least one radially extending vent is formed in an outer surface of the body and is in open communication with the conical recess, wherein the at least one radially extending vent has a length extending between the vertex of the conical recess and the mouth of the conical recess, wherein the length of the at least one radially extending vent is shorter than a length of the conical recess as measured from the vertex thereof to the mouth thereof, such that:
a) the vertex of the conical recess is formed by a first portion of the body that excludes the at least one radially extending vent and b) a second portion of the body, located directly adjacent to the mouth of the conical recess, omits the at least one radially extending vent,
wherein the conical recess is adapted for receiving a tip to be sharpened therein, and
wherein the at least one radially extending vent is configured to cool the body having the conical recess and to cool the tip during a sharpening process of the tip
