Abstract: Disclosed herein are techniques for preparation of a bone structure wherein a robotically controlled cutting bur is utilized for both milling the entry point at the outer cortical region and cannulation of the cancellous bone region for receipt of an implant. A robotic manipulator supports and moves the cutting bur and one or more controllers analyze measurements from sensors and, in response, control the robotic manipulator and/or the cutting bur for purposes such as landmark detection to determine entry point, avoiding tool skiving at entry point, and avoidance of cortical wall breach during cannulation. Also described are techniques for managing feed rate, rotational cutting speed, or mode of operation depending on operational conditions surrounding various stages of cannulation. A control interface is also provided to enable the user to manage or adjust cutting bur operation and feed rate.

Abstract: A method for performing a revision surgery using a robotic-assisted surgery system includes determining information related to an interface area between an implant component and a bone, and generating a planned virtual boundary associated with a portion of the interface area to be removed in a representation of the implant and the bone, based at least in part on the information related to the interface area. The method further includes tracking movement in the physical space of a cutting tool such that movement of the cutting tool is correlated with movement of a virtual tool, and providing a constraint on the cutting tool while the cutting tool removes the portion of the interface area. The constraint is based on a relationship between the virtual tool and the planned virtual boundary. The portion of the interface area is removed to remove the implant component from the bone.

Abstract: A fiber optic tracking sensor includes at least three optical fibers, each optical fiber having a plurality of fiber optic sensors along a length of a sensing portion of the sensor. A shape-memory member is coupled to the three optical fibers and provides support to the sensor. The at least three optical fibers are arranged in a spaced apart relationship, each offset from a central longitudinal axis of the sensor.

Abstract: A method for intraoperative planning and facilitating a revision arthroplasty procedure includes displaying a virtual model of a bone, capturing positions of a tracked probe as the tracked probe contacts points at a perimeter of a primary implant component coupled to the bone, generating a virtual representation of an interface between the primary implant component and the virtual model of the bone using the positions of the tracked probe, planning a bone resection using the virtual representation of the interface, and guiding execution of the bone resection.

Abstract: Surgical systems and methods involve manipulation of a bone. A robotic manipulator supports and moves a surgical tool that has a cutting bur rotatable about a cutting axis. Controller(s) control the manipulator to align the cutting axis to a target axis associated with the bone and advance the cutting bur along the target axis towards a cortical region of the bone. The controller(s) control the surgical tool to rotate the cutting bur about the cutting axis and contact the cortical region. The controller(s) detect, from sensor(s), forces applied to the cutting bur by the cortical region and compare the sensed forces to a threshold indicative of skiving of the cutting bur relative the cortical region. In response to the sensed forces exceeding the threshold, the controller(s) adjust control of the manipulator and/or surgical tool to reduce forces applied to the cutting bur by the cortical region.

Abstract: A robotic system and methods for performing spine surgery are disclosed. The system comprises a robotic manipulator with a tool to hold a screw and to rotate the screw about a rotational axis. The screw is self-tapping and has a known thread geometry that is stored by one or more controllers. A navigation system tracks a position of a target anatomy. Movement of the robotic manipulator is controlled to maintain the rotational axis of the surgical tool along a planned trajectory with respect to the target anatomy based on the tracked position of the target anatomy. In autonomous or manual modes of operation, the rotational rate of the screw about the rotational axis and/or an advancement rate of the screw linearly along the planned trajectory is controlled to be proportional to the known thread geometry stored in the memory.

Abstract: A method for intraoperatively planning and facilitating a revision arthroplasty procedure. The method includes capturing positions of a tracked probe as the tracked probe contacts an interface area between a bone and a primary implant component implanted on the bone, intraoperatively generating a virtual boundary corresponding to a portion of the interface area to be removed to detach the primary implant component from the bone using the positions of the tracked probe and without use of pre-operative medical imaging, facilitating removal of the primary implant component from the bone by providing a constraint on operation of a cutting tool while the cutting tool removes the portion of the interface area, the constraint based on a relationship between the cutting tool and the virtual boundary.
