Abstract:
1. A wound debridement instrument for treating wounds, comprising: an elongate handle having a distal end, a proximal end, and a middle portion between the proximal and distal ends; an elongate tubular blade body extending along a longitudinal axis from the handle distal end and terminating at a blade body distal end, the tubular blade body curving about the longitudinal axis but extending less than 360° about the longitudinal axis so that an elongate gap is defined between first and second blade side edges that extend proximally from the blade body distal end, and a cavity is defined within the tubular blade body; a first point along the blade body distal end being spaced a first longitudinal distance from the handle distal end and a second point along the blade body distal end being spaced a second longitudinal distance from the handle distal end, the first longitudinal distance being greater than the second longitudinal distance so that a plane containing both the first and second points is disposed at an angle less than 90° relative to the longitudinal axis; a sharpened blade edge defined at the blade body distal end, the blade edge being curved about the longitudinal axis and defined by the curvature of the tubular blade body, the entire sharpened blade edge lying in the plane that is disposed at an angle less than 90° relative to the longitudinal axis; and a scraping element extending proximally from the handle proximal end, the scraping element comprising an elongate scraping edge.
