A sturdy, rigid, endotherapy device used with a compatible rigid cystoscope for the removal of hard/tough tissue (e.g., calculi) in the urinary tract during a cystoscopic procedure. It is typically a very long instrument with one sliding and one stationary rod whose distal ends are equipped with sharp-edged, scoop-shaped jaws attached to pivoted handles that, when squeezed together, close the jaws to bite (cut) through tissue. It is introduced into the body through an artificial orifice or the working channel of the endoscope. This is a reusable device.
