Abstract: A surgical system, method, and non-transitory computer readable medium involving a robotic manipulator configured to move a surgical instrument relative to virtual boundaries. A navigation system tracks each of a first object, a second object, and the surgical instrument. The first object is moveable relative to the second object. One or more controllers associate a first virtual boundary with the first object and associate a second virtual boundary with the second object. The first virtual boundary is moveable in relation to the second virtual boundary. The controller(s) control the robotic manipulator in relation to the first virtual boundary to facilitate interaction of the surgical instrument with the first object. The controller(s) control the robotic manipulator in relation to the second virtual boundary to avoid interaction of the surgical instrument with the second object.

Abstract: A surgical system for manipulating an anatomy includes a surgical tool, a robotic manipulator configured to support and move the surgical tool, and one or more controllers that activate a first virtual boundary delineating a first portion of the anatomy that is allowed to be removed by the surgical tool from a second portion of the anatomy that is protected from removal by the surgical tool. The one or more controllers control the robotic manipulator for enabling the surgical tool to perform fine cutting of the first portion in relation to the first virtual boundary. The one or more controllers control the robotic manipulator for enabling the surgical tool to perform bulk cutting of the second portion of the anatomy.

Abstract: A surgical manipulator and method of operating the same. The surgical manipulator includes an arm with a plurality of links and joints, wherein an angle between adjacent links forms a joint angle. The arm includes a distal end configured to support a surgical instrument with an energy applicator. At least one controller is coupled to the arm and models the surgical instrument and the energy applicator as a virtual rigid body. The controller(s) determine a commanded pose for the surgical instrument and the energy applicator based on a summation of a plurality of forces and/or torques, wherein the plurality of forces and/or torques are selectively applied to the virtual rigid body to emulate orientation and movement of the surgical instrument and the energy applicator. The controller(s) determine commanded joint angles for the arm that place the surgical instrument and the energy applicator according to the commanded pose.

Abstract: A tool path generator utilizes a solid body model of a volume to generate a tool path for a manipulator to remove material of the volume with an energy applicator in a semi-autonomous mode. A material logger monitors movement of the energy applicator according to a cutting path taken by a practitioner in the manual mode, identifies material of the volume to which the energy applicator has been applied in the manual mode, and updates the solid body model based on the identified material. The tool path generator modifies the tool path based on the updated solid body model such that, for the semi-autonomous mode, the modified tool path accounts for the identified material of the volume to which the energy applicator has been applied in the manual mode.

Abstract: A robotic system and methods are disclosed. A common axis is defined for an instrument and an energy applicator extending from the instrument. A manipulator has a plurality of links and actuators configured to move the links to position the instrument and energy applicator. A force/torque sensor coupled to the manipulator generates an output in response to forces/torques applied to the instrument. Controller(s) defines a centering point that intersects the common axis. Controller(s) model the instrument and the energy applicator as a virtual rigid body and determine forces/torques to apply to the virtual rigid body, which are determined, in part, based on the output of the force/torque sensor. Controller(s) control the manipulator to advance the energy applicator based on the determined forces/torques applied to the virtual rigid body and reorient the instrument such that the common axis pivots about the centering point during advancement of the energy applicator.

Abstract: A user control device for a surgical system. The surgical system includes a robotic manipulator to support and move a surgical instrument that has an energy applicator. One or more controllers operate the robotic manipulator in a semi-autonomous mode and calculate an instrument feed rate, which is the velocity at which the energy applicator advances along a tool path in the semi-autonomous mode. The user control device includes a housing configured as a pendant configured to be held in one hand of a user. A first control member is mounted to the housing and can be depressed to initiate operation of the robotic manipulator in the semi-autonomous mode. A second control member is mounted to the housing and can be depressed to modify the instrument feed rate in the semi-autonomous mode.

The controller(s) control the robotic manipulator in relation to the second virtual boundary to avoid interaction of the surgical instrument with the second object.

Abstract: Systems and methods are disclosed involving an instrument, an instrument tracking device for tracking movement of the instrument, a first boundary tracking device for tracking movement of a first virtual boundary associated with an anatomy of a patient to be treated by the instrument, and a second boundary tracking device for tracking movement of a second virtual boundary associated with a periphery of an opening in the patient to be avoided by the instrument. One or more controllers receive information associated with the tracking devices including positions of the instrument relative to the first and second virtual boundaries, detect movement of the first and second virtual boundaries relative to one another, and generate a response upon detecting movement of the first and second virtual boundaries relative to one another.

Abstract: Disclosed herein are systems and methods for bone preparation with designed areas having accurate tolerance profiles to enable improved initial fixation and stability for cementless implants and to improve long-term bone ingrowth/ongrowth to an implant. One method includes preparing a bone surface to receive a prosthetic implant thereon by resecting the bone surface using a first cutting path to create a first resected region and resecting the bone of the patient using a second cutting path to create a second resected region at least partially overlapping the first resection region. The second cutting path is different than the first cutting path and either manual or robotic cutting tools can be used for creating the first and second resected regions.
