Abstract: A system including a registering device for registering a center of rotation of a hemispheric reamer in computer-assisted surgery may include: a hollow body defining an inner cavity having an open end configured for receiving a hemispheric reamer therethrough. The inner cavity has a frustoconical or conical abutment surface of a right circular cone having a central axis, the frustoconical or conical abutment surface configured for abuttingly receiving the hemispheric reamer therein. When the hemispheric reamer is at a closest point to an apex of the right circular cone while abuttingly received against the frustoconical or conical abutment surface, a center of rotation of the hemispheric reamer is on the central axis of the right circular cone, whereby a concurrent tracking of the registering device and of the hemispheric reamer sets the center of rotation for the hemispheric reamer.

Abstract: To address technical problems facing knee arthroplasty resection validation, the present subject matter provides a tracked knee arthroplasty instrument for objective measurement of resection depth. By performing a precise comparison between the location of the tracked knee arthroplasty instrument and a reference location, the knee arthroplasty instrument measures and validates each tibial and femoral resection. To address technical problems facing validation of joint laxity following knee arthroplasty, the tracked knee arthroplasty instrument is shaped to validate the flexion gap and extension gap. When the tracked knee arthroplasty instrument is inserted between the resected tibial plateau and femoral head, the instrument shape validates whether the desired flexion gap and extension gap have been achieved.

Abstract: A method for registering output of sensor-enabled implants with a bone axis during robotically-assisted arthroplasty procedures comprises registering anatomy of a patient to a surgical tracking system, determining a bone axis of a bone of the anatomy using the surgical tracking system, preparing the bone to receive a prosthetic implant including an orientation sensor, inserting the prosthetic implant into the bone, obtaining orientation output from the orientation sensor, and shifting the orientation output from the orientation sensor to align with the bone axis. A system for registering output of sensor-enabled implants with a bone axis during robotically-assisted arthroplasty procedures comprises a surgical robot comprising an arm configured to move within a coordinate system, a tracking system configured determine locations of one or more trackers in the coordinate system, a sensor-enabled implant configured to implanted into anatomy and output orientation data, and a controller for the surgical robot.

Abstract: Techniques for robotically guiding a cup-shaped implant or instrument are provided. In an example, the technique can include a combination of the following operations. Acquiring a calibration image including a cup-shaped element in a first orientation. Identifying a first elliptical outline of the cup-shaped element. Acquiring a navigation image including the cup-shaped element in a second orientation. Identifying a second elliptical outline of the cup-shaped element. Aligning a coordinate system of a robotic system to a patient, and positioning an implant or instrument based on a pre-operative plan within the coordinate system.

Abstract: A surgical tool assembly may include a first component, a second component, a tracker device connected at least to the first component. A quick connect system for releasably connecting the first component to the second component, the quick connect system including a male and female engagement, a latch mechanism for latching the first component to the second component. Complementary features are on the first component and on the second component to ensure a planned positional alignment between the first component and the second component upon latching of the male and female engagement, for tracking of the second component with the tracker device.

Abstract: Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.
