Surgical devices controllable by surgical robotic systems

A surgical device configured to be controlled by a surgical robotic system, comprising:

• a housing capable of being coupled to the surgical robotic system;
• a drive system at least partially mounted in the housing;
• a shaft rotatably coupled to the drive system at a first end of the shaft;
• a tissue-removal assembly coupled to a second end of the shaft, wherein the tissue-removal assembly comprises:
• a first cutting member having a plurality of rotatable blades, wherein the first cutting member is coupled to the second end of the shaft,
• a second cutting member,
• one or more support elements extending from the first cutting member and slidably or fixedly coupled to the second cutting member, and
• one or more extendable elements extending from the first cutting member and slidably or fixedly coupled to the second cutting member,
• wherein the one or more support elements and the extendable elements are extendable and retractable to adjust the position of the second cutting member with respect to the first cutting member.
