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

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 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.

A method of performing a procedure includes preparing a subject, gaining access to a portion of the subject with a first instrument, removing a first portion of the portion of the subject with the first instrument, gaining access to the portion of the subject with a tracked instrument, moving the tracked instrument to a surface revealed by removal of at least the first portion from the portion of the subject, tracking the tracked instrument while moving at least the tracked instrument to the surface, and determining a representation of the surface based on the tracking the tracked instrument.

Systems and methods for a robotic-assisted revision procedure

A method for debriding an infected implant area using a robotic-assisted surgery system. The method includes determining, by a processing circuit associated with a computer, an area to be debrided, the debridement area including at least a surface of an implant or patient tissue, and generating, by the processing circuit, a plan for debriding the debridement area. The method further includes controlling a debridement tool, by the robotic-assisted surgery system, while the debridement tool is used to carry out the debridement plan, and monitoring the debridement by the processing circuit.

Systems and methods for robotic infection treatment of a prosthesis

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.

A robotic system for performing spine surgery. The robotic system comprises a robotic manipulator and a navigation system to track a surgical tool relative to a patient's spine. The robotic system may be controlled manually and/or autonomously to place implants in the patient's spine.

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.

A method for performing an open wedge osteotomy includes providing a fixation plate defining a first aperture and a second aperture and creating a first hole and a second hole in a bone. The fixation plate is coupled to the bone by aligning the first aperture of the fixation plate and the first hole of the bone and inserting a fastener through the first aperture and into the first hole. A cut is created through at least a portion of the bone to create a first resected surface and a second resected surface after creating the first hole and the second hole. The method further includes moving the first resected surface and the second resected surface relative to each other until the second aperture of the fixation plate is aligned with the second hole of the bone. The fixation plate is coupled to the bone by inserting a second fastener through the second aperture of the fixation plate and into the second hole of the bone.

Methods and systems for planning and performing an osteotomy

A method for determining a resection volume of a pathologic femur having a femoral head and a femoral neck is provided. The method may determine a first point of a desired contour based on a pathologic alpha angle of the pathologic femur, determine a second point of the desired contour based on a desired alpha angle of the pathologic femur, determine a third point of the desired contour on the femoral neck of the pathologic femur, and generate a resection volume of the pathologic femur based on the first, second and third points of the desired contour.
