Abstract
A reamer attachment system for attaching a reamer to a robotic arm comprises a reaming guide comprising a guide shaft and a collar attached to the guide shaft, a reamer shaft extending through the collar to articulate against the collar, and a reamer lock couplable to the reamer shaft to engage the collar and prevent axial displacement of the reamer shaft relative to the collar while permitting the reamer shaft to articulate against the collar. A method for collaborative reaming of a bone between a surgical robot and a surgeon comprises positioning a reamer guide at a location in a coordinate system for the surgical robot system using a robotic arm of the surgical robot, coupling a reamer to the reamer guide such that a reamer axis passes through the location, constraining movement of the reamer along the reamer axis, and pivoting the reamer at the location to remove bone.
