Abstract
A surgical system for cutting tissue of a patient includes an outer housing and a reciprocating assembly structurally configured to carry a cutting tool in a reciprocating motion. An actuator knob is manually accessible to the user and may be fixed axially to the outer housing. The reciprocating assembly may reciprocate relative to the actuator knob. The actuator knob may be configured for rotational movement between a lock position and an unlock position. The system may also include a locking mechanism configured to retain a cutting tool within the reciprocating assembly. The locking mechanism may be responsive to movement of the actuator knob to maintain the tool within the output shaft when the actuator knob is in the lock position and permit removal of the tool when the actuator knob is in the unlock position. Surgical cutting tools, such as blades include thickness enhancing features.
