ABSTRACT:
A surgical scalpel (10) is provided with a retractable guard (11) for its cutting blade (12). The guard (11) is mounted on the handle (24) of the scalpel (10) for sliding movement between an advanced position in which the blade (12) is covered and a retracted position in which the blade (12) is exposed. The guard (11) may be moved with one hand, and the surgeon, nurse and/or assistant does not have to take his or her eyes away from the patient or the instrumentation during a surgical procedure. A two-position resiliently-biased manually-releasable detent member (29), is disposed within the longitudinal center plane (30) of the handle (24) and extends above the handle (24). A cut-out (49) on the bottom wall (15) of the guard (11), together with the detent member (29), facilitates the one-hand actuation of the guard (11). A slot (25) on the guard (11) and a pin (26) or the handle (24), limits the sliding movement of the guard (11) independently of the detent action. Two embodiments are disclosed.
