Abstract: A surgical robotic system is provided comprising a wrist comprising a surgical instrument and an elongated shaft configured to transmit actuation forces from a drive assembly to the spherical wrist to actuate rotation of the spherical wrist. The surgical instrument is a hinged surgical instrument comprising jaws, wherein the jaws are biased in a normally open position by a resilient biasing element, wherein the surgical instrument is actuatable by the drive assembly towards a closed position by a preloaded string which runs from the drive assembly through the elongated shaft to the surgical instrument and which preloads the surgical instrument.

Abstract: A surgical robotic system is provided including a suspension structure, a manipulator arm for holding a surgical instrument, one or more actuators to adjust a pose of the manipulator arm, and a control system configured to establish a master-slave coupling between a user input device as a master device and the manipulator arm as a slave device. The manipulator may be manually reconfigurable from a first configuration in which the manipulator arm assumes a first pose to a second configuration in which the manipulator arm assumes a second pose which is mirrored with respect to the first pose about a mirroring plane which runs through a tip of the surgical instrument. The control system may temporarily disable the master-slave coupling the enable said manual reconfiguration, and after the manual reconfiguration, resume the master-slave coupling from the second pose.

Abstract: A surgical robotic system is provided comprising a wrist for holding a surgical instrument, an elongated shaft comprising an actuation transmission mechanism for the wrist, and a strut assembly comprising at least three struts which are with respective proximate strut sections flexibly attached to different parts of a base structure and with respective distal strut sections to each other to form a pyramidal structure. The wrist is attached to at least one of said distal strut sections, and each strut is actuatable in longitudinal direction to provide three translational degrees of freedom for positioning the surgical instrument in the workspace. The elongated shaft forms one of the struts of the strut assembly.

Abstract: Some embodiments are directed to a surgical robotic system including a suspension structure 1, a carriage 2 arranged to be mounted to the suspension structure, and a manipulator arm 3 arranged to be detachably docked to the carriage via a docking mechanism. The docking mechanism includes a first docking connector on the manipulator arm and a second docking connector on the carriage. The first and the second docking connector may establish an electrical connection between the manipulator arm and the carriage when the manipulator arm is docked. The manipulator arm includes a connector for connecting the manipulator arm via a cable to an electric power supply, and be configured to supply the carriage with the electrical power via the electrical connection when the manipulator arm is docked.

Abstract: Some embodiments are directed to a robotic manipulator interface for coupling a hinged surgical tool to a manipulator of a surgical robot, the interface including a first interface member to be coupled to the manipulator, and a second interface member to be coupled to the first interface member, the second interface member being arranged to mount the hinged surgical tool, wherein the first interface member includes a pinching mechanism for pinching the hinged surgical tool when the second interface member is coupled to the first interface member, wherein the pinching mechanism includes two movable protrusions protruding from a surface of the first interface member, the first interface member including a built-in actuating mechanism for moving the protrusions to each other to push two arms of the mounted hinged surgical tool towards each other so as to actuate the mounted hinged surgical tool through the sterile drape.

Abstract: Designs for modular microsurgical robotic devices and systems are provided, which could include one or multiple master-slave units coupled to a central microscope-based suspension structure. One of the main objectives is to provide robotic assistance during tasks which require long-term user concentration and high precision. The microsurgical robotic devices pay attention to motion scaling and tremor filtration in a 6 Degrees-of-Freedom (DOF) master-slave setup with force feedback. An extra DOF is included to actuate a 1-DOF instrument tip. Embodiments of this invention can be used in the medical environment as well as in other areas such as printed circuit board repair, watch and jewelry making, laboratory tasks, or other areas which require high precision over extended periods of time.
