Abstract
A surgical instrument includes a reusable component and a limited-use component releasably engagable with the reusable component. The limited-use component is configured for one or more uses and includes a clocking mechanism configured to count each engagement of the reusable component and the limited-use component to one another. The clocking mechanism is incrementally transitionable upon each successive count from one or more uses state, wherein the clocking mechanism permits both mechanical engagement and electrical coupling of the reusable component and the limited-use component to one another, to a spent state, wherein the clocking mechanism inhibits both mechanical engagement and electrical coupling of the limited-use component and the reusable component to one another.
