  • Patent number: 8679133
    Abstract: A wound debridement instrument for treatment of chronic wounds has an elongate handle with a distal end, a proximal end, and a middle section. An elongate tubular blade body extends distally from the handle distal end and terminates at a distal cutting edge. The tubular body defines a cavity and has a longitudinal axis. The distal cutting edge follows the arc of the tubular body and is angled relative to the longitudinal axis. In some embodiments the tubular body is an incomplete tube, having a longitudinally-extending gap formed therein. Some embodiments may also have a scraping element extending proximally from the handle proximal end.

  • Patent number: 5217263
    Abstract: A quick release clip molded of either aluminum or plastic for mounting on a window or door frame for securing a screen. Six such clips are equally spaced around the frame for latching cooperation with the screen. The clip is formed of a base secured to the frame by a press-fitting or a screw, a lever pivoted to one edge of the base and a clamp pivoted to a surface of the lever. Integral male and female cooperating snap parts on the lever and the base, respectively, secure the clip in latching position.
