Patent number: 5366133Abstract: A surgical fastener applying apparatus is provided with a shipping interlock to prevent premature actuation of the apparatus by the jostling and vibrations which normally occur during shipment of the apparatus from the supplier to the user. The shipping interlock includes a projection extending from the cam bar retainer and initially disposed through an elongated aperture in an interlock plate having an open distal end. The aperture has a narrow neck portion through which the projection can pass only with sufficient force applied to the cam bar retainer. The shipping interlock is adapted to permit passage of the projecting member when the force exceeds the normally expected forces from jostling of cargo to insure that actuation of the apparatus is intentional.Type: GrantFiled: November 24, 1992Date of Patent: November 22, 1994Assignee: United States Surgical CorporationInventor: Robert J.
