Abstract
A surgical instrument that may include a housing, a transducer engaged with the housing which can produce vibrations, and an end-effector engaged with the transducer. The surgical instrument can further include an adjustable sheath extending from the housing where the sheath is movable relative to the distal tip of the end-effector and where the distance between the distal tip of the sheath and the distal tip of the end-effector can be set such that the sheath can act as a depth stop. The sheath can be adjusted such that, when the distal tip of the sheath contacts the tissue or bone being incised, the surgeon can determine that the appropriate depth of the incision has been reached. In other embodiments, the end-effector can be moved with respect to the sheath in order to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.

24. A surgical instrument, comprising:
-
a housing; a transducer supported within said housing, wherein said transducer is configured to produce vibrations; an end-effector engaged with said transducer, wherein said end-effector defines an axis and a distal tip, wherein said distal tip is movable relative to said axis by vibrations produced by said transducer, wherein said end-effector is configured to be detached from said transducer, and wherein said transducer is configured to receive a different end-effector; and a clamp including a jaw member movably supported relative to said end-effector between an open position and a closed position. - View Dependent Claims (25, 26, 27, 28, 29, 30)

32. A surgical instrument, comprising:
-
a housing; a transducer engaged with said housing, wherein said transducer is configured to produce vibrations; an end-effector engaged with said transducer, wherein said end-effector defines an axis and a distal tip, wherein said distal tip is movable relative to said axis by vibrations produced by said transducer, wherein said end-effector is configured to be assembled and disassembled with said transducer, and wherein said transducer is configured to be assembled with a different end-effector; and a clamp, wherein said clamp includes a jaw member and a pivot, wherein said jaw member is rotatable with respect to said end-effector about said pivot, wherein said jaw member is detachable from said clamp. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40)
