Publication number: 20130304076Abstract: A surgical instrument comprising a symbol formed in or on a smooth surface surrounding the symbol, wherein the symbol comprises 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. These ridges and grooves create an improved contrast for the symbol relative to the surrounding surface by a combination of different specular reflection of incident light compared to the surrounding surface and shadows formed by the ridges and grooves. A method of marking a surgical instrument with a symbol formed in or on a smooth surface is also described. The method 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, wherein the angled surfaces define a plurality of parallel ridges and grooves in the symbol.Type: ApplicationFiled: January 4, 2012Publication date: November 14, 2013Applicant: DEPUY (IRELAND)Inventors: Oliver Coultrup, Duncan Young

Publication number: 20130289575Abstract: A protractor for use with an external fixation frame is provided. The protractor may include a face having angle designations thereon and a set of opposed and extending flanges projecting from said face. The flanges may connect to a portion of an external fixation frame, such as a ring (or other component) of the frame. The face may also include a post member to which a rotatable dial is mounted. An elongate member may be pivotally connected to a portion of the post member and may include a clamp. The clamp may be used to connect to an alternate portion of an external fixation frame, such as a strut of the frame. Thus, the protractor may be connected to two points on an external fixation frame so as to measure the angle between such points. Related methods of using the aforementioned protractor are also disclosed.Type: ApplicationFiled: April 26, 2012Publication date: October 31, 2013Applicant: STRYKER TRAUMA GMBHInventors: Adam John Edelhauser, Jan Heinsohn
