Abstract: The present disclosure relates to systems, methods, and tools for tool tracking using image-derived data from one or more tool located reference features. A method includes: directing illuminating light from a light source onto a robotic surgical tool within a patient body, wherein the tool includes a plurality of primitive features having known positions on the tool, and wherein each feature includes a spherical reflective surface; capturing stereo images of the plurality of primitive features when the tool is within the patient body, wherein the stereo images are captured by an image capture device adjacent the illumination source so that the illumination light reflected from the imaged primitive features toward the image capture device substantially aligns with spherical centers of the surfaces of the imaged primitive features, and determining a position for the tool by processing the stereo images so as to locate the spherical centers of the imaged primitive features by using the reflected light.

Abstract: A system and process for performing orthopedic surgery is provided that uses a patient's existing implant as a registration tool in an orthopedic surgical procedure. The systems and processes may be used with computer assisted systems or navigation systems to aid in the removal of bone, bone cement, or a bone prosthesis, typically a bone prosthesis used in hip replacement surgery, knee replacement surgery, and the like. The removal of the prosthesis may be done by conventional methods, with navigation systems, robotic assistance or articulating hand held systems. The removal of bone and/or bone cement may be performed with navigated systems, robotic systems, articulating hand-held systems and combinations thereof.

Abstract: Example methods and systems to facilitate osteocutaneous free flap reconstructions are provided. One example method involves causing a surgical navigation system to display a representation of a patient undergoing surgery; receiving input data representing one or more osteotomies made during the surgery to form a defect within the patient; determining a donor site for a bone graft having a contour that corresponds to the defect within the patient using a geometric alignment algorithm to identify, as the donor site, a portion of the bone graft that virtually aligns with the defect; generating a virtual template representing the bone graft; displaying the generated virtual template representing the bone graft within the representation of the patient as a navigational guide for harvesting of the bone graft; and displaying the generated virtual template positioned into the defect within the representation as a navigational guide for reconstructing the defect using the harvested bone graft.

Abstract: A computer-assisted surgery system may have a robotic arm including a surgical tool and a processor communicatively connected to the robotic arm. The processor may be configured to receive, from a neural monitor, a signal indicative of a distance between the surgical tool and a portion of a patient's anatomy including nervous tissue. The processor may be further configured to generate a command for altering a degree to which the robotic arm resists movement based on the signal received from the neural monitor; and send the command to the robotic arm.

Abstract: A pre-operative planning and manufacturing method for orthopedic surgery includes obtaining pre-operative medical image data representing a joint portion of a patient. The method also includes constructing a three-dimensional digital model of the joint portion and manufacturing a patient-specific alignment guide for the joint portion from the three-dimensional digital model of the joint portion when the image data is sufficient to construct the three-dimensional digital model of the joint portion. The patient-specific alignment guide has a three-dimensional patient-specific surface pre-operatively configured to nest and closely conform to a corresponding surface of the joint portion of the patient in only one position relative to the joint portion. The method further includes determining, from the image data, a size of a non-custom implant to be implanted in the patient and assembling a surgical kit including the non-custom implant when there is insufficient image data to construct the patient-specific alignment guide therefrom.

Abstract: The invention relates to a surgical method of attachment of a first bony segment in relation with a second bony segment, both segments belonging to a same bone, which comprises the steps of: milling said bone and cutting it partially, to separate it in two bony segments linked together by a bony hinge distracting both bony segments around said hinge; fitting an osteotomy implant into the cavity thus obtained; attaching said implant to both bony segments; wherein it comprises the preoperative steps of: determining the position and the direction of the future partial cut, calculating its depth, calculating the relative three-dimensional positions of both bony segments to obtain the final desired alignment of the two bony segments, choosing among several osteotomy implants, one which is wider than the largest distance between the facing sides of said bony segments after distraction, determining the position and the shape of the future implant reception cavity and calculating its dimensions, deducing therefrom the shape of the two part cavities to be milled in the bone before the distraction step.
