A cinch assembly affixed to a surgical drape may include at least two pairs of links connected by a hinge joint, with each link foldable relative to one another about the hinge joint between an unfolded configuration and a folded configuration. A portion of the surgical drape may be in an extended configuration when the pairs of links are in the unfolded configuration and may be in a gathered configuration when the pairs of links are in the folded configuration. The cinch assembly may further include at least two alignment and attachment element assemblies including first and second attachment elements configured to align with and engage with first and second complementary attachment elements of equipment of a surgical system.

Mechanism for managing and retaining a surgical drape

A sheath for a surgical instrument may include a sleeve having a distal end and proximal end, and a retention mechanism at a proximal end portion of the sleeve. The retention mechanism may comprise a sleeve attachment portion configured to be attached to the sleeve at the proximal end portion, and a locking collar extending from the sleeve attachment portion, wherein the locking collar is configured to receive a connector portion of a surgical instrument. The locking collar further may include a locking feature movable between a first configuration, in which the sheath is moveable relative to the surgical instrument, and a second configuration, in which the locking feature is configured to engage with the connector portion to retain the sheath in position on the surgical instrument.

Sheathes for surgical instruments, and related devices and methods

A computer-assisted system includes an instrument manipulator assembly including a preload assembly and a motor, an insertion assembly configured to control a position of the instrument manipulator assembly, and a motor controller coupled to the preload assembly. The motor controller is configured to actuate the preload assembly to control an amount of preload applied by the preload assembly to the motor and actuate the preload assembly to apply a low preload in response to detecting that a sterile adapter is mounted to the instrument manipulator assembly.

Controller controlled instrument preload mechanism

A surgical drape assembly can include a surgical drape; and a cinch assembly affixed to the surgical drape. The cinch assembly can include a folding mechanism having a plurality of links and at least two hinge joints respectively connecting respective adjacent links of the plurality of links. The plurality of links can be foldable relative to one another about the at least two hinge joints between an unfolded configuration and a folded configuration. A first portion of the surgical drape is in an extended configuration in the unfolded configuration with a portion of the drape being in a gathered configuration in the folded configuration of the plurality of links.

A wound retractor includes a sleeve with proximal and distal ends, an inner ring inside the sleeve between the proximal and distal ends, and an outer ring outside the sleeve between the proximal and distal ends. The inner ring includes a tapered outer surface that increases in diameter from a proximal end of the inner ring toward a distal end of the inner ring. The outer ring includes a tapered inner surface that increases in diameter from a proximal end of the outer ring toward a distal end of the outer ring. A portion of the sleeve is captured between the tapered outer surface and the tapered inner surface.

Auto-locking wound retractor

A computer-assisted teleoperated system includes a pre-load assembly in an instrument manipulator that is under the control of a controller. The controller can automatically cause the preload assembly to engage and disengage a preload. A surgical apparatus includes an instrument manipulator assembly and a sterile adapter assembly. The sterile adapter assembly is mounted in the distal face of the instrument manipulator assembly. When the preload assembly configures the instrument manipulator assembly to apply a preload force on the sterile adapter assembly, the sterile adapter assembly is removable from the distal face of the instrument manipulator. The sterile adapter assembly includes a mechanical sterile adapter assembly removal lockout and a mechanical instrument removal lockout.
