Abstract: A surgical system includes a dynamic preload tension feature for a tensioning element that actuates a distal end comport 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: Drive assemblies for surgical clamping and cutting instruments, as well as surgical clamping and cutting instruments using these drive assemblies, are disclosed. The drive assemblies may include a drive member, a locking member mounted to the drive member, and a spring. The drive member may be configured to releasably engage at least one of a knife or a shuttle of a surgical clamping and cutting instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member may be movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. The spring may be configured to bias the locking member toward the second position.

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.
