Abstract: An adapter for removably coupling a tracker to a surgical handpiece includes a proximal member having an interface configured to engage and prevent rotation of the proximal member relative to the surgical handpiece, a distal member slidably and rotatably coupled to the proximal member, a biasing member disposed between the proximal distal members and configured to urge the proximal and distal members in opposing directions, and a tracking array mount coupled to the distal member. The biasing member is configured to be compressed by a reference feature of the end effector and the surgical handpiece when the distal member is disposed on the end effector and the end effector is coupled to the surgical handpiece, the compressed biasing member creating a frictional force between the distal and proximal members that resists rotation of the distal member relative to the proximal member.

Abstract: A navigation system for navigating a medical instrument is provided. The system includes a localizer, a tracking array, and a processor. The tracking array has a first tracking face and a second tracking face which are coupled to one another and collectively include a plurality of optical tracking elements. The processor is configured to measure relative positions of the plurality of optical tracking elements while visible to the localizer, measure relative positions of the at least one optical tracking element of the first tracking face and at least one optical tracking element of the second tracking face while visible to the localizer at the same time, and create a composite rigid body based on the measured relative positions of at least one optical tracking element of the first tracking face and the at least one optical tracking element of the second tracking face while visible at the same time.

Abstract: An optical tracker usable with a surgical object, the optical tracker includes a tracker frame including a mounting body, which defines an instrument engaging aperture having a longitudinal axis, and an offset body protruding proximally from the mounting body. The instrument engaging aperture is configured to receive a proximal region of the surgical instrument such that the longitudinal axis of the tracker is aligned with an axis of the surgical instrument. The tracker may further include a tracking array coupled to the tracker frame and comprising a mounting fixture and a plurality of LED emitters coupled thereto. The optical tracker may further comprise at least three apex points defined by the tracker frame that extend to a height above the LED emitters.
