Abstract: Systems and methods according to embodiments of the present disclosure include: receiving registration data including information about a location of an anatomical element in a surgical environment; defining, based on the registration data, a three-dimensional (3D) volume in the surgical environment including the anatomical element; and controlling a robotic arm inside the surgical environment based on the defined 3D volume such that at least the robotic arm or one or more components attached to the robotic arm avoids passing through the defined 3D volume during a movement of the robotic arm.

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.
