First Claim
1. A surgical instrument, comprising:
- a transducer configured to produce vibrations;
an end-effector engaged with said transducer, wherein said end-effector defines an axis and a distal tip, and wherein said distal tip is movable relative to said axis by vibrations produced by said transducer; and
an adjustable depth stop movably supported relative to said end-effector, wherein said depth stop includes a distal tip, and wherein said distal tip of said depth stop is movable relative to said distal tip of said end-effector.

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.
