Abstract: Disclosed herein is a surgical instrument configured for attachment to a surgical device. The surgical instrument includes a distal region having a curved internal surface configured to mate with a curved external surface of the surgical device, a rotational locking feature that limits rotational movement of the instrument with respect to the surgical device, and an axial locking feature that limits axial movement of the blade with respect to the surgical device. Methods of using the surgical instruments include sliding the axial locking feature past a corresponding axial locking feature on the surgical device, locking the axial locking feature to the corresponding axial locking feature on the surgical device (thereby limiting axial movement of the elongated blade with respect to the surgical device), adjusting the position of the surgical device using the surgical instrument, and disengaging the axial locking feature (for example, by using a disengagement instrument).

Abstract: A dish-cleaning appliance comprising a sink having a bowl defining a wash chamber with an open top for providing access to the wash chamber. A liquid recirculation system is provided for spraying liquid throughout the wash chamber. A drain conduit can be provided, alone or in combination with the recirculation system, for draining liquid from the wash chamber when the drain is closed. A fill control system is provided to ensure that the dishwashing cycle is not started with liquid in the wash chamber and that the sink drain is properly closed. One or more sensors can be provided for enabling the fill control system. The sensors can be located within the drain above the location where the drain is plugged.
