Abstract:
An actuation input mechanism for a teleoperated surgical instrument may include an interface structure and a shaft connected to the interface structure. The interface structure may be engageable with a drive structure of an actuation interface assembly of a teleoperated surgical system to be driven by the drive structure. The shaft may be rotatable in response to the interface structure being driven. The interface structure may comprise a depression shaped and sized to receive a fingertip. The interface structure may further comprise one or more gripping features disposed in the depression. A surgical instrument for a teleoperated surgical system may include an instrument shaft, an end effector, and a force transmission mechanism. The force transmission mechanism may comprise an actuation input mechanism to transmit drive forces to actuate the surgical instrument, the actuation input mechanism including an interface structure and a shaft.
Abstract:
A surgical instrument includes a shaft with a proximal end and a distal end, a movable component coupled at the distal end of the shaft, a force transmission mechanism coupled at the proximal end of the shaft, and an actuation element with a first end coupled to the force transmission mechanism and a second end coupled to the movable component. The actuation element being configured to transmit an actuation force from the force transmission mechanism to the movable component. A coil spring is coupled to the actuation element between the first and second ends. First and second ends of the coil spring are coupled to longitudinally separated locations on the actuation element. The coil spring is configured to passively expand and contract in response to tension changes in the actuation element. A distance between the longitudinally separated locations changes as the coil spring passively expands and contracts.
Abstract:
A method for providing a visual indication regarding a state of an instrument comprises sensing usage information about the instrument and using a motor to rotate an indicator body from a first position to a second position in response to sensing the usage information meets a predetermined condition. The method further comprises holding the indicator body in the first position or the second position, respectively. In the first position a first portion of the indicator body is visible on an exterior of the instrument and in the second position a second portion is visible. In the first position, the first portion of the indicator body provides a visual indication that the usage information of the instrument does not meet the predetermined condition, and in the second position the second portion of the visual indicator body provides a visual indication that the usage information of the instrument meets the predetermined condition.

Abstract:
An instrument sterile adapter couples a surgical instrument and an instrument carriage. The instrument sterile adapter includes an instrument plate that provides a first surface to receive the surgical instrument and a latch plate joined to the instrument plate. The latch plate includes a second surface to receive the instrument carriage and latch structures. Each latch structure has a carriage latch arm that extends away from the second surface of the latch plate and an instrument latch arm joined to the carriage latch arm. The instrument latch arm extends through the instrument plate and away from the first surface of the instrument plate. A connecting member flexibly connects the carriage latch arm and the instrument latch arm to a remainder of the latch plate. The connecting member may be perpendicular to the latch arms. The latch arms may engage fixed locking surfaces in the instrument carriage and the surgical instrument.
