摘要:
A fiber optic tracking system for tracking substantially rigid object(s) is described. The fiber optic tracking system includes a light source, an optical fiber having a sensing component configured to modify optical signals from the light source, the optical fiber being configured to attach to the substantially rigid object, a detection unit arranged to receive the modified optical signals from the sensing component, and a calculation unit configured to determine a pose of the substantially rigid object in six degrees of freedom based on the modified optical signals.

The invention relates to a surgical system and, more particularly, to a surgical system and method for verifying calibration of a surgical device. The surgical system or method can be configured to perform the steps of: identifying an interface on an anatomy of a patient, determining a position of a checkpoint of the interface in a coordinate frame of reference, contacting the interface with a portion of a surgical tool of the surgical device, determining a position of the portion of the surgical tool in the coordinate frame of reference, and determining whether the position of the portion of the surgical tool has an expected correspondence to the position of the checkpoint. The interface may comprise a painted portion of a bone of the patient, a divot made in the bone, or a mechanical interface that includes a portion configured to be affixed to the bone and an interface portion that is configured to be contacted by the portion of the surgical tool.

The description relates to surgical computer systems, including computer program products, and methods for implant planning using corrected captured joint motion information. Data representative of a corrected limb pose at a plurality of poses within a range of motion of a joint associated with a particular individual is captured, the joint comprising a first bone and a second bone, while the first bone, the second bone, or both are subject to a corrective force aligning the first and second bones in a desired alignment. The first bone of the joint is represented. The second bone of the joint is represented. A first implant model is associated with the representation of the first bone. A second implant model is associated with the representation of the second bone. Based on the captured data, a relationship is determined between the first implant model and the second implant model at one or more poses of the plurality of poses within the range of motion of the joint. Information representative of the determined relationship is displayed.

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.

Described are computer-based methods and apparatuses, including computer program products, for implant planning using areas representing cartilage. A predetermined number of control points for generating a predetermined number of areas representing cartilage are determined, wherein the predetermined number of control points are based on an implant component. Measurements corresponding to a plurality of measured cartilage points are received, wherein each cartilage point is based on an associated control point from the predetermined number of control points. A plurality of areas representing cartilage are generated, wherein each area representing cartilage is larger than and projects to an associated control point from the plurality of control points. A representation of the implant component is positioned based on a representation of a bone, the representation of the bone comprising representations of the plurality of areas representing cartilage.

摘要:
A probe is provided. The probe may include a shaft portion rotatably attachable to a position sensing device, a nonlinear portion at least partially removed from a center axis of the shaft portion, and a tip disposed at a distal end of the nonlinear portion and positioned on the center axis. The nonlinear portion may be selectably rotatable about the center axis to one of a plurality of rotational orientations. The tip may have a substantially constant position relative to the position sensing device.
