Abstract:
1. A surgical device, comprising: a cannula defining a longitudinal axis; a rotatable cutter supported within the cannula and being configured to cut tissue for passage of the cannula through the tissue, the rotatable cutter including a distal edge; a first driver drivable by a motor arrangement and configured to rotate the rotatable cutter; at least one sensor assembly comprising a movable sensing tip, the movable sensing tip being offset radially from the rotatable cutter, the movable sensing tip including a distal edge and a proximal edge, the proximal edge of the movable sensing tip connects to a biasing member, the biasing member urging the movable sensing tip distally with respect to the rotatable cutter, wherein in a first position, the distal edge of the movable sensing tip extends beyond the distal edge of the rotatable cutter and wherein in a second position, the distal edge of the movable sensing tip and the distal edge of the cutter, are aligned along a plane which is perpendicular to the longitudinal axis of the surgical device, the second position being configured to signal the first driver to rotate and translate the rotatable cutter; and a memory device disposed in the surgical device and being configured to store data relating to at least one of, an operation of the surgical device and an identification of the surgical device, wherein the stored data is used to control an operation of the surgical device.
