ABSTRACT:
A dermatome for improved cutting of tissue comprises: a blade assembly, including a blade and a blade carrier; a rotational drive assembly; and a housing which engages the blade assembly to constrain the movement of any point on the blade assembly to bidirectional linear movement over a predefined linear range, wherein the engaged blade assembly forms a cover for the housing so that the housing in combination with the engaged blade assembly defines a closed space which surrounds the rotational drive assembly while the blade assembly moves over the predefined linear range. The entire blade assembly may be releasable from the housing, or the blade may be releasable from the blade carrier which remains non-releasably engaged with the housing.
