Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A high frequency coaxial connector adaptor assembly for mating an APC-7 precision connector member to any of a set of coaxial connectors including N type, TNC type, and SMA type connectors. The invention utilizes a first connector body having an APC-7 interface at one end and having an open structure at the other end with an extended center conductor and outer conducting bushing to interface with any one of the set of coaxial connectors which are specially adapted at one end to engage the open structure of the first connector body. This structure permits an integral structure which does not significantly degrade or distort high frequency signals coupled to the coaxial connector while permitting interchangeable coaxial interfaces.
