Abstract: A positioning system for a robotic-surgery device comprises a lower portion comprising a pillar section extending from a wheeled base, an upper portion supported by the pillar section and comprising a docking interface adapted for securing thereto a motor-control unit of a robotic-surgery device, and electronic circuitry programmed to cause the upper portion to simultaneously displace vertically and pitch about a pitch-axis member mediating between the pillar section and the upper-portion, in response to a remote user input, so as to pivot a robotic-surgery device secured to the docking interface about a distal end of a surgical arm proximally seated in a surgical-arm-receiving volume of the motor-control unit.

Abstract: Devices for implanting inside an eye and for holding an intraocular lens (IOL) are presented; the device being operable to rotate the IOL, around an optical axis of the IOL, by absorbing energy from a remote energy source; the device comprises: a stator portion configured to be fixedly positioned inside the lens capsule of the eye; a rotor portion configured to be fixedly attached to the IOL; and a movement system operable to cause rotation of the rotor portion and the IOL, the movement system comprises a plurality of actuators and at least one interaction region associated with the plurality of actuators, the plurality of actuators comprise at least two actuators operable to cause the rotation of the rotor portion and the IOL in each of the clockwise and counterclockwise angular directions, the plurality of actuators and the at least one interaction region being aligned such that at each given moment in time, each actuator of the plurality of actuators is aligned differently with respect to the interaction r

Abstract: A method of operation of an input arm for control of a surgical mechanical arm, the input arm comprising a plurality of rigid segments coupled to each other by joints, at least one of said plurality of rigid segments shaped and sized to be at least partially held by a user's hand, the method comprising: grasping the input arm and manipulating the input arm by moving the rigid segments relative to each other; wherein during grasping and manipulating, electrical power is supplied to at least one brake configured in each of the joints to unlock the brake from a normally locked state; at any selected position of the plurality of rigid segments, entering a pause mode by ceasing the electrical power supply to the at least one brake in each of the joints to thereby lock each of said joints and maintain the plurality of rigid segments in place.
