Abstract: Some embodiments are directed to a surgical robotic system for use in a surgical procedure, including a surgical arm having a movable arm part for mounting of a surgical instrument having at least one degree-of-freedom to enable longitudinal movement of the surgical instrument towards a surgical target. Some other embodiments are directed to a human machine interface for receiving positioning commands from a human operator for controlling the longitudinal movement of the surgical instrument, and an actuator configured for actuating the movable arm part to effect the longitudinal movement of the surgical instrument, and controlled by a processor in accordance with the positioning commands and a virtual bound. The virtual bound establishes a transition in the control of the longitudinal movement of the surgical instrument in a direction towards the surgical target. The virtual bound is determined, during use of the surgical robotic system, based on the positioning commands.

Abstract: Some embodiments are directed to a surgical master-slave robot for use in minimally (or reduced) invasive surgery on a subject. The robot includes an instrument manipulator for mounting of a surgical instrument, and a linkage system for moveably suspending the instrument manipulator. A first linkage component is configured for guiding a first suspension to move along a first movement trajectory. A second linkage component is configured for guiding a second suspension point to move along a second movement trajectory. The first movement trajectory and the second movement trajectory differ and are selected to provide a combined translational and rotational movement of the instrument manipulator which moves the instrument manipulator along a predefined trajectory from a surgical position to a standby position. The robot may provide a stable removal of the instrument manipulator during a surgery as well as sufficient surgeon's workspace after the removal of the instrument manipulator.
