Abstract: Systems and methods for registering one or more anatomical elements are provided. The system may comprise an imaging device and a navigation system configured to track a pose of a marker coupled to an object and configured to identify the marker. A first image may be received from a surgical plan. Pose information describing the pose of the marker and a marker identification of the marker may be obtained from the navigation system. An object identification based on the marker identification may be retrieved from a database. Image data of a second image depicting an anatomical element and the object may be obtained from the imaging device. The image data, the pose information, and the object identification may be input into a registration model. The registration model may be configured to register the anatomical element to the first image based on the pose information and the object identification.

Abstract: A system for skive avoidance includes a sensor configured to measure a force exerted on a surgical tool; at least one processor; and a memory. The memory stores instructions for execution by the at least one processor that, when executed, cause the at least one processor to: project a tool trajectory onto a three-dimensional (3D) model of bone tissue; and estimate an expected normal force direction and magnitude upon contact of the surgical tool with the bone tissue.

Abstract: Methods and systems for providing a safety mechanism for a robotically controlled surgical tool. Embodiments of the methods use sensors to detect parameters that vary by the tissue traversed by a surgical tool. The sensors detect signals arising from the interaction of the surgical tool with the tissue and provide this information to a robotic controller. For example, during drilling, the sensors may measure power, vibration, sound frequency, mechanical load, electrical impedance, and distance traversed according to preoperative measurements on a three-dimensional image set used for planning the tool trajectory. By comparing the detected output with that expected for the tool position based on the planned trajectory, identified discrepancies in output would indicate that the tool has veered from the planned trajectory. The robotic controller may then alter the tool trajectory, change the speed of the tool, or discontinue power to the tool, thereby preventing damage to underlying tissue.
