SURGICAL KNIFE AND TOOLS ADAPTED FOR SIMPLIFIED BLADE REMOVAL

摘要

A knife (10) has a handle (15) with a mount (16) for affixing a removable blade (11). A concave surface (17) of the mount supports an elongate protrusion (18) for engaging a complementary slot (12) in the blade and reaches a landing (20) rearward of the tip that is exposed when the blade is mounted on the handle with a surface of the blade being completely supported by the concave surface. A channel (25) in the landing is dimensioned such that a rearmost part (26) thereof remains exposed when the blade is mounted on the handle. The blade is removed by inserting a curved lever (30) into the channel underneath a rearmost part of the blade and swiveling the lever so as to disengage the blade from the elongate protrusion.

1. A knife (10) adapted for receiving a removable blade (11), said knife comprising:
a handle (15) having a mount (16) for affixing the blade, said mount having a concave surface (17) supporting an elongate protrusion (18) for engaging a complementary slot (12) in the blade, the concave surface reaching a landing (20) located sufficiently rearward of the tip so as to remain exposed when the blade is mounted on the handle with a surface of the blade being completely supported by said concave surface, and a channel (25) in said landing dimensioned such that a rearmost part (26) thereof remains exposed when the blade is mounted on the handle; thereby allowing the blade to be removed by inserting a curved lever (30) into the channel underneath a rearmost part of the blade and swiveling the lever so as to disengage the blade from the elongate protrusion.
