Abstract
A surgical knife assembly in which a blade is provided with a guard for limiting the depth of cut. The guard is formed of a resilient material such as plastic, and frictionally grips the blade, so that the guard is adjustable on the blade by the application of a predetermined amount of axial force, with the force required for adjustment being considerably greater than the force that is applied thereto during a cutting procedure. An adjustment tool is also provided, the tool and the blade having cooperative engaging portions to permit accurate adjustment of the position of the guard on the blade between incisions during a surgical procedure.
