Spinal surgery systems and methods include a manipulator with a robotic arm and an end effector. A navigation system with a localizer tracks a patient and the manipulator. A control system registers, with the navigation system, a desired trajectory for a vertebra of the patient and detects that the end effector is within a predetermined distance to the desired trajectory. In response to the end effector being within the predetermined distance and detection of a user input, the control system autonomously moves the robotic arm to align the end effector to the desired trajectory. The end effector is constrained to the desired trajectory with a line haptic object and can exit the line haptic object in response to being moved along the line haptic object until the end effector reaches an exit point defined relative to the line haptic object.

Robotic spine surgery system and methods

Surgical systems and methods involve a robotic manipulator with a force sensor and a surgical tool that holds a screw. The screw has a known thread geometry. A navigation system tracks a pose of a target anatomy. Controller(s) store the known thread geometry and control the robotic manipulator to maintain the rotational axis on a planned trajectory with respect to the target anatomy based on the tracked pose of the target anatomy. The controller(s) detect, with the force sensor, a force applied by a user. The controller(s) control a rotational rate of the surgical tool to rotate the screw about a rotational axis and an advancement rate of the surgical tool to linearly advance the screw along the planned trajectory. The rotational rate and the advancement rate are based on the force applied by the user and are proportional to the known thread geometry.

A method of robotically evaluating soft tissue characteristics of a joint includes measuring, by a robotic device, information about a joint during a controlled range of motion manipulation of the joint; determining a motion limit of the joint, using the information about the joint measured during the controlled range of motion manipulation of the joint, wherein the motion limit is at least one of a displacement limit or a force limit of the joint; and replicating, using a joint positioner controlled by the robotic device, the controlled range of motion manipulation of the joint while introducing perturbations to the joint, wherein the replicated range of motion manipulation is controlled, at least in part, based on the motion limit. The method further includes using data obtained by the computer-assisted surgery system during the range of motion manipulation with perturbations to characterize the constraints of a soft tissue envelope of the joint.

Systems and methods for robotic soft tissue evaluation

A method includes controlling a robotic system using a virtual boundary and based on optical tracking of a tracker, detecting a condition in which an optical detection device is occluded from detecting the tracker, and maintaining the virtual boundary if the condition persists for shorter than a predetermined period of time.

Surgical system with occlusion detection

A method includes controlling a robotic arm extending from a base in a free mode during a registration procedure and optically tracking the base and a marker mounted on the robotic arm during movement of the robotic arm in the free mode. The movement of the robotic arm causes movement of the marker without affecting a position of the base. The method also includes defining a coordinate transformation based on a position of the base and a plurality of tracked positions of the marker achieved during the movement of the robotic arm in the free mode and controlling the robotic arm using the coordinate transformation.

Surgical system with free mode registration

A method for intraoperatively augmenting a revision implant includes removing a primary implant from a bone, intraoperatively determining a size of a defect of the bone, intraoperatively cutting a bone filler material to the size of the defect, installing the bone filler material at the defect, and installing the revision implant on the bone.

Systems and methods for guiding a revision procedure

A method includes obtaining a model of a bone of a patient, identifying a plurality of landmarks of the model of the bone, defining a plane of the patient, determining an axis based on the plurality of landmarks and the plane, and planning a planned pose of an implant relative to the bone based on a relationship between a model of the implant, the axis, and the plane.

System and method for surgical planning

A surgery system includes a mechanical hub, an anatomy support structure coupled to the mechanical hub, a first moveable support structure, and an imaging system comprising a source element and a detector element. The imaging system is coupled to the mechanical hub via the first moveable support structure such that the source element and the detector element are repositionable relative to the anatomy support structure. The surgical system also includes a second moveable support structure coupled to the mechanical hub and a surgical instrument coupled to the mechanical hub via the second moveable support structure.

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

Surgical system for positioning prosthetic component and/or for constraining movement of surgical tool

A surgical system includes a surgical robot with an end effector that supports a drive assembly, a manual interface, and a trigger assembly. A cutting tool is attached to the drive assembly and rotatable about a cutting axis. A method includes positioning, with the surgical robot, the cutting tool relative to a surgical site to align the cutting axis with a predetermined trajectory. A user engages the trigger assembly for rotating the cutting tool about the cutting axis with the drive assembly and advancing the cutting tool along the predetermined trajectory at the surgical site to a first depth. A user applies force to the manual interface for rotating the cutting tool about the cutting axis and advancing the cutting tool along the predetermined trajectory to a second depth greater than the first depth.
