    Abstract: A system comprises a robotic arm in a robotic arm coordinate system, a camera in a fixed pose in a navigation coordinate system, at least one processor, and memory including instructions that when executed by the at least one processor, cause the at least one processor to determine a pose of the robotic arm within the navigation coordinate system, map the robotic arm coordinate system to the navigation coordinate system based on the pose of the robotic arm, and control, based on output of the camera, the robotic arm in the navigation coordinate system.

    Abstract: Systems and methods for tracking a pose of a target and/or tracking the target is provided. A first robotic arm may be configured to orient a first imaging device and a second robotic arm may be configured to orient a second imaging device. The first robotic arm and the second robotic arm may operate in a shared or common coordinate space. A first image may be received from the first imaging device and a second image may be received from the second imaging device. The first image and the second image may depict at least one target. A pose of the at least one target may be determined in the coordinate space based on the first image, a corresponding first pose, the second image, and a corresponding second pose.

    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.

    Abstract: A bone connection system for attaching a surgical robot having its base mounted in the vicinity of a patient, to a bone of the patient. The system incorporates a switchable bone connection unit attached between the bone and a support element of the robot. This unit has a locked state in which the bone is attached essentially rigidly to the support element, and a released state in which the bone can move relative to the support element. The unit comprises a force sensor for determining the force exerted between the bone and the support element of the robot, and a position sensor for measuring the position of the bone relative to the support element of said robot. The unit switches from its locked state to its released state when the force exceeds a predetermined level, selected to ensure that the bone can move without detaching any bone connection elements.

    Abstract: Automatic dilator devices for generating minimally invasive access apertures for surgical procedures or endoscopic surveillance. The automatic dilators comprise a number of spreader tubes nested one inside the other. The devices deploy automatically by means of coupled mechanical mechanisms which insert one spreader after the other distally into the patient's tissue. Each spreader moves distally into the tissue by means of a screwing action, by which rotation is converted into linear motion of the neighboring spreader, immediately external to it, by means of interaction between a helical thread form on a surface of a spreader being engaged by a section of thread, or by one or more protrusions on the opposing face of the next spreader external to the rotating spreader. Such a combination of helical thread and follower enables a rotatory mechanism to be used to deploy one nested spreader tube after the other, by continuous rotary motion.
