Abstract: A surgical system includes a robotic arm, a straight end effector configured to be coupled to the robotic arm, an offset end effector configured to be coupled to the robotic arm, and a controller configured to control the robotic arm using first control logic when the straight end effector is coupled to the robotic arm and second control logic when the offset end effector is coupled to the robotic arm.

Abstract: An end effector for a computer-assisted surgical system includes a mount configured to be coupled to an arm and a housing coupled to the mount and configured to interchangeably support a first operating member and a second operating member. When the housing supports the first operating member, the housing is configured to prevent translation of the first operating member relative to the mount. When the housing supports the second operating member, the housing is configured to allow translation of the second operating member relative to the mount along a first axis.

Abstract: A surgical system for positioning a prosthetic component includes a robotic arm and a surgical tool having an end effector configured to be coupled to the robotic arm. The system further includes a controller programmed to generate control signals, based on a planned pose of the prosthetic component, that cause the robotic arm to allow movement of the surgical tool in at least one degree of freedom and to constrain movement of the surgical tool in other degrees of freedom, wherein the controller is programmed to generate control signals that cause the robotic arm to maintain the constraint as the prosthetic component is implanted on the anatomy.

Abstract: A surgical system for positioning a prosthetic component includes a surgical tool and a force system configured to provide a force to the surgical tool. The system further includes a controller programmed to: compare an actual pose of a prosthetic component engaged by the surgical tool and a target pose of the prosthetic component, and generate control signals that cause the force system to allow movement of the surgical tool within a range of movement and to provide a force to constrain movement of the surgical tool beyond the range of movement. The force resists movement of the surgical tool that would cause substantial deviation between an aspect of the actual pose of the prosthetic component and a corresponding aspect of the target pose. The controller is programmed to generate control signals that cause the force system to maintain the force as the prosthetic component is implanted on the anatomy.

Abstract: A surgical system includes a surgical tool configured to be coupled to a cutting element, a force system configured to provide at least some force to the surgical tool, and a controller programmed to generate control signals. The control signals cause the force system to provide a first constraint on a user's manual movement of the surgical tool when the cutting element is a first cutting element and provide a second constraint, different from the first constraint, on a user's manual movement of the surgical tool when the cutting element is a second cutting element.

Abstract: Morphing or fitting a brain atlas to a diagnostic image data set of the patient, or to a patient registered to the brain atlas, is enhanced using measurements of one or more physical characteristics of the brain taken with the aid of an instrument as it is being inserted into the brain. The measurements are then compared against known physical characteristics of certain brain structures, thus permitting correlation of the measured physical characteristic to a brain structure. The brain atlas then may be morphed or deformed so that the identified brain structure in the atlas is at or near the position at which the measurement was taken, as known from the tracked position of the instrument.
