Retractable protection and/or sensing features for powered surgical cutting devices and systems

A surgical cutting device, comprising:

• a handle;
• a shaft assembly extending distally from the handle, the shaft assembly including at least one shaft;
• a cutting tool extending at least partially through the shaft assembly, the cutting tool extending distally from the shaft assembly and including a distal cutting tip configured to cut tissue along a longitudinal axis defined through the cutting tool and an exposed annular perimeter configured to cut tissue transverse to the longitudinal axis upon lateral movement of the cutting tool, the cutting tool adapted to connect to a motor configured to drive the cutting tool to cut tissue;
• a retractable shield defining a distal face surrounding an opening extending through at least a portion of the retractable shield, the retractable shield defining a transverse cutting area therein, the retractable shield coupled to the shaft assembly and at least one of the retractable shield or the cutting tool movable relative to the other between a retracted position, wherein the distal tip of the cutting tool extends through and distally beyond the opening and distally from the retractable shield to enable the distal tip to cut tissue via the rotation of the cutting tool, and one or more extended positions, wherein the retractable shield encapsulates the distal tip of the cutting tool to protect the distal tip of the cutting tool and prevent distal engagement with tissue during rotation thereof and restricts the cutting tool to cutting tissue transversally within the transverse cutting area upon activation and lateral movement thereof, and
• a sensor disposed on the distal face of the retractable shield.
