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: 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.

Abstract: A robotic surgical system comprises an instrument chassis having a proximal mounting section and a distal mounting section. The system also comprises an instrument guide movably coupled to the distal mounting section and an actuator coupled to the proximal mounting section. A linkage system operably interconnects the actuator and the instrument guide to transmit motion from the actuator to the instrument guide.
