Abstract: A method initiates and/or prepares a teleoperation by a robotic system for medical or surgical teleoperation. A hand-held master device is mechanically unconstrained and moved by an operator. A slave device includes a microsurgical instrument controlled by the master device. The robotic system includes a man-machine interface allowing the operator to communicate the intention to teleoperate to the robot. The method includes initiating teleoperation preparation; then performing alignment between master device and slave device, in which the slave device moves to align orientation of the surgical instrument to the master device. Teleoperation is entered after the alignment master and slave devices has been completed. First checks are conducted for entering the alignment, and enabling start of the alignment only if all first checks are passed. Before entering the teleoperation, second checks are conducted for enabling alignment, and enabling entry into teleoperation only if all second checks are passed.

Abstract: A method initiates and/or prepares and/or conducts teleoperation by a robotic system for medical or surgical teleoperation. The robotic system includes a master device, which is hand-held, mechanically unconstrained and moveable by an operator, and a slave device including a surgical instrument controlled by the master device. The master device is functionally symmetrical with respect to a predeterminable single, longitudinal axis of the master device. A local reference frame of the master device and the related longitudinal axis is detected, with respect to a main reference frame of the master device workspace; then, functionally equivalent local reference frames are detected. A corresponding target reference frame is mapped in a workspace of the slave device. An operating reference frame is detected according to criteria for optimization of the trajectory of the slave device. A robotic system for medical or surgical teleoperation is control led by the control method.

Abstract: A dispensing apparatus for dispensing a lid from a stack of lids each having a lid periphery includes a load platform having a main floor on which to place a stack of lids, the main floor sloping downward from an apex in a rearward direction, the load platform having a forward slope inclined downward from the apex in a forward direction. A parallelogram mechanism is mounted to move in a linear direction forward to a dispense position and rearward to a home position. A hinge is coupled to the parallelogram mechanism and has a handle with a distal end oriented upward and forward to contact an inner surface of a lid periphery of a bottommost lid of the stack of lids when the parallelogram mechanism moves forward from the home position toward the dispense position.
