摘要:
A surgical instrument includes a reusable component and a limited-use component. The reusable component includes a first electrical contact. The limited-use component is releasably engagable with the reusable component. The limited-use component includes a second electrical contact configured to electrically couple to the first electrical contact to establish electrical communication between the reusable component and the limited-use component. The second electrical contact is movable from a first position, wherein the second electrical contact is positioned to electrically couple to the first electrical contact upon engagement of the limited-use component and the reusable component to one another, to a second position, wherein the second electrical contact is positioned to inhibit electrical coupling to the first electrical contact upon engagement of the limited-use component and the reusable component to one another.
