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: An instrument sterile adapter (310) couples a surgical instrument (120) and an instrument carriage (130). The instrument sterile adapter (310) includes an instrument plate (430) that provides a first surface to receive the surgical instrument (120) and a latch plate (400) joined to the instrument plate (430). The latch plate (400) includes a second surface to receive the instrument carriage (130) and latch structures. Each latch structure has a carriage latch arm (410) that extends away from the second surface of the latch plate (400) and an instrument latch arm (405) joined to the carriage latch arm (410). The instrument latch arm (405) extends through the instrument plate (430) and away from the first surface of the instrument plate (430). A connecting member (425) flexibly connects the carriage latch arm (410) and the instrument latch arm (405) to a remainder of the latch plate (400). The connecting member (425) may be perpendicular to the latch arms (405). The latch arms (405) may engage fixed locking surfaces in the instrument carriage (130) and the surgical instrument (120).

Abstract: An indicator mechanism for a surgical instrument includes an aperture fixed to a base. An indicator body is rotatably supported by the base. The indicator body includes features for engaging a motor that rotates the indicator body. A visual indicator, visible through the aperture, is coupled to the indicator body. A detent mechanism holds the indicator body in one of two positions. A first of the two positions provides a visual indication that the surgical instrument is in service and a second of the two positions provides a visual indication that the surgical instrument is expired. A controller may track use events for a surgical instrument to determine expiration. Use events may include operations and conditions in addition to those that occur in the surgical instrument. When the use events tracked by the controller indicate expiration, the controller may rotate a motor to set the visual indication to expired.

Abstract translation: 用于外科器械的指示器机构包括固定到基座的孔。 指示体由基座可旋转地支撑。 指示器主体包括用于接合旋转指示器主体的马达的特征。 通过孔眼可见的视觉指示器耦合到指示体。 定位机构将指示器主体保持在两个位置中的一个位置。 两个位置中的第一位置提供外科器械正在使用的视觉指示，并且两个位置中的第二位置提供手术器械到期的视觉指示。 控制器可以跟踪外科器械的使用事件以确定到期。 使用事件可能包括手术器械中发生的操作和条件。 当由控制器跟踪的使用事件指示到期时，控制器可以旋转电动机以将视觉指示设置为过期。
