Abstract: A medical device drive system can include a rotational input, a coupling member engaged with the rotational input, a first gear having an engagement feature sized and shaped to engage with the coupling member, and a second gear coupled with the first gear, the second gear coupled to a movable element. The system can have a first system state and a second system state. In the first system state the coupling member is not engaged with the engagement feature and the first gear rotates without moving the coupling member. In the second system state the coupling member is engaged with the engagement feature of the first gear and rotation of the rotational input turns the coupling member, the first gear, and the second gear to move the movable element.

Abstract: A surgical instrument includes: a distal movable component; a proximal drive assembly including a drive shaft, a capstan, and a plurality of splines; a first cable extending between the distal movable component and the drive shaft; and a second cable extending between the distal movable component and the capstan. The drive shaft includes a tapered projection, and the capstan includes a tapered bore in which the tapered projection of the drive shaft is received. The plurality of splines engage the tapered projection of the drive shaft with the tapered bore of the capstan.

Abstract: A medical device system can include a surgical tool, and a one-way input, and a drive system operatively coupled to the surgical tool and the oneway input device. The drive system can be rotatable in a first direction to effectuate a first operation of the surgical tool, and rotatable in a second direction to effectuate a second the operation of the surgical tool. The one-way input device can be operable to rotate the rotatable drive system in the second direction but not the first direction.

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.
