  • Patent number: 11980430
    Abstract: Embodiments of the present disclosure provide a surgical robot system may include an end-effector element configured for controlled movement and positioning and tracking of surgical instruments and objects relative to an image of a patient's anatomical structure. In some embodiments the end-effector may be tracked by surgical robot system and displayed to a user. In some embodiments the end-effector element may be configured to restrict the movement of an instrument assembly in a guide tube. In some embodiments, the end-effector may contain structures to allow for magnetic coupling to a robot arm and/or wireless powering of the end-effector element. In some embodiments, tracking of a target anatomical structure and objects, both in a navigation space and an image space, may be provided by a dynamic reference base located at a position away from the target anatomical structure.

  • Publication number: 20240090884
    Abstract: A surgical robot system includes a robot having a robot base and a robot arm coupled to the robot base, and a surgical retractor. The surgical retractor includes a retractor frame, a coupler, blades, a force and/or torque sensor, and a force and/or torque feedback determination unit. The retractor frame includes arms that are translatably and/or pivotably connected to the retractor frame. The coupler releasably attaches the retractor frame to the robot arm. The blades are each coupled to and extend away from a distal end of one of the arms. The force and/or torque sensor is connected to the blades and indicates an amount of force and/or torque being applied to the blades from contact with material of a surgical site. The force and/or torque feedback determination unit determines the amount of force and/or torque being applied to the blades based on the indication.
