Abstract: A surgical system includes a surgical tool configured to be coupled to a cutting element, a force system configured to provide at least some force to the surgical tool, and a controller programmed to generate control signals. The control signals cause the force system to provide a first constraint on a user's manual movement of the surgical tool when the cutting element is a first cutting element and provide a second constraint, different from the first constraint, on a user's manual movement of the surgical tool when the cutting element is a second cutting element.

Abstract: A surgical apparatus includes a surgical device, configured to be manipulated by a user to perform a procedure on a patient, and a computer system. The computer system is programmed to create a representation of an anatomy of a patient; to associate the anatomy and a surgical device with the representation of the anatomy; to manipulate the surgical device to perform a procedure on a patient by moving a portion of the surgical device in a region of the anatomy; to control the surgical device to provide at least one of haptic guidance and a limit on manipulation of the surgical device, based on a relationship between the representation of the anatomy and at least one of a position, an orientation, a velocity, and an acceleration of a portion of the surgical device; and to adjust the representation of the anatomy in response to movement of the anatomy during the procedure.

Abstract: A surgical system for positioning a prosthetic component on an anatomy of a patient includes a surgical tool configured to engage the prosthetic component, a force system configured to provide at least some force to the surgical tool, and a controller programmed to compare a target pose of the prosthetic component and an actual pose of the prosthetic component engaged by the surgical tool and generate control signals that cause the force system to allow movement of the surgical tool within a range of movement and provide haptic feedback to constrain a user's ability to manually move the surgical tool beyond the range of movement. The haptic feedback resists movement of the surgical tool by the user that would cause substantial deviation between at least one aspect of the actual pose of the prosthetic component and a corresponding aspect of the target pose of the prosthetic component.

Abstract: A surgical planning method is provided. A representation of a bone of a joint is created. The joint is moved to a first position. A first point corresponding to a first location in the joint is identified when the joint is in the first position. The joint is moved to a second position. A second point corresponding to a second location in the joint is identified, when the joint is in the second position. Bone preparation for implanting an implant on the bone is planned based at least in part on the first and second points.

Abstract: A method of conducting a sinus lift procedure is provided. A secure and physical interaction is formed between a fiducial device and a site within a patient's mouth to form a fiducial marker. A virtual incising plan is formed for incising the patient's maxilla, with respect to the fiducial marker, for providing access to a sinus membrane. Movement of an incising device is physically regulated with respect to the fiducial marker with a guidance device. The incising device is in physical communication with the fiducial marker via the fiducial device. The guidance device physically regulates movement of the incising device, according to the virtual incising plan and corresponding with physical manipulation of the incising device by a user, to incise the maxilla. Tactile feedback is provided to the user, via the incising device, if the physical manipulation of the incising device by the user deviates from the virtual incising plan.

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.

Abstract: A system and method for determining inclination and version of a prosthetic acetabular cup relative to a coronal radiographic plane is provided. The system and method include the identification of a coronal radiographic plane in a three dimensional medical image. The system and method further include the identification of two symmetric landmarks on the pelvis to determine a mediolateral axis. The version and inclination can then be calculated based on the relationship between the axis of the acetabular cup, the coronal radiographic plan, and the mediolateral axis.

Abstract: A portable measurement system is provided including a probe, a user interface control and a receiver. The probe includes a plurality of ultrasonic transducers that emit ultrasonic waveforms for creating a three-dimensional sensing space. The user interface control captures a location and position of the probe in the three-dimensional sensing space. The receiver includes a plurality of microphones to capture the ultrasonic waveforms transmitted from the probe to produce captured ultrasonic waveforms and a digital signal processor that digitally samples the captured ultrasonic waveforms and tracks a relative location and movement of the probe with respect to the receiver in the three-dimensional ultrasonic sensing space from time of flight waveform analysis. Embodiments are demonstrated with respect to hip replacement surgery, but other embodiments are contemplated.

Abstract: The description relates to surgical computer systems, including computer program products, and methods for implant planning using captured joint motion information. Data is captured representative of a range of motion of a joint associated with a particular individual, where the joint includes a first bone and a second bone. The first bone of the joint is represented and a first implant model is associated with the representation of the first bone. Based on the captured data, a relationship is determined between the first implant model and a representation of the second bone through at least a portion of the range of motion of the joint. Information is displayed representative of the determined relationship.

Abstract: A system is disclosed for enhancing video by use of a virtual surface. One or more positions are identified in a first image. These one or more positions are transformed to one or more locations in relation to the virtual surface. In subsequent video images (e.g. fields, frames, or other units), the one or more locations in relation to said virtual surface are transformed to one or more positions in the subsequent video images. The subsequent video images are enhanced based on the one or more transformed positions.
