Abstract

A method of marking a surgical instrument with a symbol formed in or on a smooth surface comprises forming a symbol in or on a smooth surface of the surgical instrument; and forming a plurality of angled surfaces over at least part of the area of the symbol. The angled surfaces define a plurality of parallel ridges and grooves in the symbol. The steps of forming the symbol and forming the plurality of angled surfaces take place substantially simultaneously in a single step.

Claims (9)

1 . A method of marking a surgical instrument with a symbol formed in or on a smooth surface, the method comprising:

forming a symbol in or on a smooth surface of the surgical instrument; and

forming a plurality of angled surfaces over at least part of the area of the symbol,

wherein the angled surfaces define a plurality of parallel ridges and grooves in the symbol; and

wherein the steps of forming the symbol and forming the plurality of angled surfaces take plane substantially simultaneously in a single step.

2 . The method of claim 1 wherein the symbol and plurality of angled surfaces are formed in a single molding step.

3 . The method of claim 1 further including a step selected from the group of polishing or roughening the plurality of angled surfaces or the smooth surface to produce a different surface roughness in the plurality of angled surfaces compared to the smooth surface.

4 . The method of claim 1 wherein the symbol and plurality of angled surfaces are formed in a single machining step.

5 . The method of claim 4 further including a step selected from the group of polishing or roughening the plurality of angled surfaces or the smooth surface to produce a different surface roughness in the plurality of angled surfaces compared to the smooth surface.
