ABSTRACT:
A microsurgical knife having a shroud that can be locked in two or three positions. The knife has a body with a blade at one end, and an enlarged cap at the other, the cap acting as a stop for the shroud. Grooves along the knife body receive projections on the shroud allowing the shroud to slide but not rotate. Locking grooves extend circumferentially from the grooves so the shroud can be rotated to place a projection in a locking groove and prevent inadvertent longitudinal movement of the shroud. Locking grooves are placed so the shroud can be placed in blade covering position, in the extreme rearward position, and in an intermediate position wherein the shroud acts as an enlarged centrally located handle.
