    Abstract: A method for verifying surgical tool placement includes attaching a guide sleeve to a surgical robot, the guide sleeve defining a guide sleeve axis; aligning the surgical robot such that the guide sleeve axis is directed at a predetermined target location; and attaching an aiming rod to the guide sleeve such that the aiming rod can rotate around the guide sleeve axis, the aiming rod having apertures along its length. The aiming rod is attached to the guide sleeve at an angle and position such that when the surgical robot is adjusted to align the guide sleeve axis with the predetermined target location, a center of each aperture of the apertures of the aiming rod and a center of the predetermined target location are collinear, independent of a rotational position of the aiming rod around the guide sleeve axis.

    Abstract: A robotic navigation system includes a robot base (140); a robotic arm (144) comprising a proximal portion secured to the robot base, a distal portion movable relative to the proximal portion, and a tracking marker (156) secured to the robotic arm proximate the distal portion; at least one processor; a navigation system including a tracking marker sensor configured to identify positions of the tracking marker in a first coordinate space; and a memory. The memory stores instructions that cause the at least one processor to: cause the robotic arm (144) to move to a plurality of different poses; receive information relating to a position of the tracking marker (156) in a second coordinate space when the robotic arm is in each of the plurality of different poses; and compare the positions of the tracking marker in the first coordinate space to the positions of the tracking marker in the second coordinate space.

    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.
