1. An ultrasonic surgical instrument comprising:
(a) a handle assembly;
(b) a waveguide extending distally from said handle assembly, wherein said waveguide is adapted to be acoustically coupled to an ultrasonic transducer and transmit ultrasonic energy therethrough;
(c) an end-effector located at a distal end of said waveguide; and
(d) a clamp assembly removably mounted to said handle assembly, said clamp assembly including a clamp arm pivotally mounted on the distal end of the clamp assembly for pivotal movement with respect to the end effector;
wherein said clamp assembly is removably mounted to the handle assembly by axially aligned first and second bayonet mounts, each of said bayonet mounts comprising a female bayonet coupling having at least one bayonet slot configured to matingly receive a bayonet mounting pin of a male bayonet coupling, wherein said bayonet slots are provided on said clamp assembly and extend circumferentially about a common longitudinal axis corresponding to the longitudinal axis of said waveguide.
