Abstract
A retractable surgical instrument having a transversely preformed, curved operative element extendible from a straight, linear sheath. The operative element is retained in the retracted position until the distal tip of the instrument has been positioned at a work site. Cutting edges on the curved operative element may be formed in a variety of styles, one such style being embodied as an arthroscopic knife wherein the tip of the knife blade is preformed such that it maintains a transverse curve when it is extended to an operating position. The cutting edges of the transverse knife blade may extend longitudinally from the protective sheath in which case the edges are spaced from the inside surfaces of the linear sheath by the cooperative action of a raised bearing surface on the knife and the edge of the sheath adjacent the concave side of the curve as well as by laterally extending edge protection projections.
