Abstract
A surgical tool for division of a tendon sheath having a convex outer surface, such as the A1 pulley of the finger, is disclosed. A cutting tip is configured to self-center itself and, in turn, a cutting blade carried by the cutting tip, as the cutting tip is advanced along the arcuate outer surface of the tendon sheath. The cutting tip is further configured to displace neural tissue and vascular tissue from a region proximate the cutting blade as the cutting tip is advanced along the arcuate outer surface of the tendon sheath. A retractable blade guard is disclosed. The cutting blade may be fixed, relative to the cutting tip. Alternatively, the cutting blade may be moveable from a retracted position and a deployed position, and vice-versa.
