    Abstract: A robotic surgical system comprises an instrument chassis assembly including an elongated member extending along a chassis axis, a proximal mounting section, a distal mounting section, and an instrument interface coupled to the proximal mounting section. The robotic surgical system further comprises an actuation system coupled to the proximal mounting section. The robotic surgical system further comprises a linkage system operably coupled between the actuation system and the distal mounting section. The linkage system includes an instrument guide. The robotic surgical system further comprises a surgical instrument including a proximal portion coupled with the instrument interface and a distal portion coupled with the instrument guide. The surgical instrument is pivotable via the instrument guide relative to the chassis axis.

    Abstract: A surgical system includes a dynamic preload tension feature for a tensioning element that actuates a distal end component of a surgical instrument. The surgical instrument includes a chassis at a proximal end of the surgical instrument, drive components mounted in the chassis, a distal end component at a distal end of the surgical instrument, a flexible tensioning element coupled between a first of the drive components and the distal end component, and a dynamic preload tensioner mounted in the chassis and coupled to a second of the drive components. The flexible tensioning element extends along a path. The dynamic preload tensioner is configured to be driven by the second of the drive components to be moved relative to the chassis and is positioned to change the path of the flexible tensioning element as the dynamic preload tensioner moves relative to the chassis.

    Abstract: An instrument chassis for a robotic surgical system comprises a bridge member, a first instrument guide member configured to receive a first surgical instrument, and a second instrument guide member configured to receive a second surgical instrument. Each of the first instrument guide member and the second instrument guide member is moveably coupled to the bridge member such that each of the first instrument guide member and the second instrument guide member is moveable in at least one degree of freedom relative to the bridge member. The instrument chassis further comprises a central instrument guide member coupled to the bridge member between the first instrument guide member and the second instrument guide member. The central instrument guide member is configured to receive a third surgical instrument. Each of the first instrument guide member and the second instrument guide member is slidably movable relative to the bridge member.

    Abstract: A robotic surgical method comprises providing an instrument chassis having a proximal mounting section and a distal mounting section rigidly coupled to the proximal mounting section, an instrument guide assembly movably coupled to the distal mounting section, a pair of proximal actuators coupled to the proximal mounting section, and a linkage system operably interconnecting the proximal actuators and the instrument guide assembly. The method further comprises providing first control signals to one of the proximal actuators to cause the linkage system to move the instrument guide assembly in a first rotational degree of freedom, providing second control signals to the other proximal actuator to cause the linkage system to move the instrument guide assembly in a second rotational degree of freedom, and providing third control signals to the proximal actuators to cause the linkage system to move the instrument guide assembly in a third rotational degree of freedom.
