ABSTRACT:
This invention relates to a manual surgical knife. An elongated knife blade and an elongated blade guide are rigidly and releasably clamped in spaced apart relation. The blade guide has a guide surface which overlies and has a transverse dimension substantially greater than the blade transverse dimension. The blade guide has a flat planar guide surface which faces and is spaced from the surface of the knife blade. A guide shank is affixed to and longitudinally extends from the guide. A handle is attached to the guide shank and is laterally offset from the guide surface and inclined in a direction away from the guide surface thereby defining a hand clearance. The guide has edge-supporting ribs extending generally orthogonally from the guide in a direction opposite to the guide surface.
