A medical robotic system that includes a robotically controlled surgical instrument. The body has a center through hole for liquid to flow through, and a constrictor groove formed in the center through hole and an O-shaped ring fitted in the constrictor groove. Ohmic contacts provide electrical connection to an electronic device. The search apparatus stores the retrieval data received from the information generating apparatus in a storage device, and notifies the monitoring apparatus that the retrieval data has been stored. In still another embodiment, a keyway receiver is integral with the panel adjacent one of the ends. The integrated circuit includes a contact coupled to a second side of the access device and self-aligned dielectric material isolating the first line from the contact.
