Surgical tool mechanism

摘要

The surgical tool comprises a longitudinally extending waveguide ( 1 ) defining a longitudinal axis ( 2 ). A first jaw member ( 1 b) is connected at a distal end of the waveguide ( 1 ). A longitudinally extending carrier tube ( 3 ) is rotatable about the waveguide ( 1 ) and a second jaw member ( 6 ) is pivotably mounted to a distal end of the carrier tube ( 3 ). An outer shroud ( 7 ) includes a guide lobe ( 9 ) bearing on a rearward face of the second jaw member. Rotation of the carrier tube ( 3 ) causes pivoting of the second jaw member ( 6 ) into and out of operative relationship with the first jaw member ( 1 b).
