1. An ultrasonic surgical instrument, comprising:
- a handle housing;
an outer sheath assembly protruding from said handle housing, said outer sheath assembly having at least one comb-like distal end portion having at least two spaced tooth members protruding therefrom;
at least one ultrasonic transducer movably supported by said housing;
an ultrasonic blade protruding from said at least one ultrasonic transducer and being movable therewith, said ultrasonic blade having a distal end for movement adjacent to said at least one distal end portion of said outer sheath assembly; and
a drive system interacting with said at least one ultrasonic transducer for selectively applying an actuation motion thereto to cause said at least one ultrasonic transducer to move within said handle housing.

Abstract
In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that has an ultrasonic blade that protrudes from at least one ultrasonic transducer that is movably supported within a handle housing. The ultrasonic blade protrudes through an outer sheath assembly that is attached to the handle housing. A distal end portion of the outer sheath has at least one comb-like portion formed thereon. In some embodiments, a distal end of the ultrasonic blade is axially movable adjacent to the at least one comb-like portion. In other embodiments, the distal end of the ultrasonic blade is rotatable adjacent to the at least one comb-like portion.

11. An ultrasonic surgical instrument, comprising:
-
a handle housing; an outer sheath assembly protruding from said handle housing, said outer sheath assembly having a pair of spaced comb-like members each having at least two spaced tooth members protruding therefrom; at least one ultrasonic transducer movably supported by said housing for selective gross axial travel therein; an ultrasonic blade protruding from said at least one ultrasonic transducer and being axially movable therewith, said ultrasonic blade having a distal end for movement between said pair of spaced comb-like members; and a trigger operably coupled to said handle assembly and interacting with said at least one ultrasonic transducer to selectively apply gross axial actuation motion thereto. - View Dependent Claims (12, 13, 14)

15. An ultrasonic surgical instrument, comprising:
-
a handle housing; an outer sheath assembly protruding from said handle housing, said outer sheath assembly having a pair of spaced comb-like members that each have at least two spaced tooth members protruding therefrom; at least one ultrasonic transducer supported within said handle housing for gross rotation therein; an ultrasonic blade protruding from said at least one ultrasonic transducer and being rotatable therewith, said ultrasonic blade having a distal end for rotation between said pair of spaced comb-like members; a trigger operably coupled to said handle housing; and a series of gears interfacing with said at least one ultrasonic transducer and said trigger such that actuation of said trigger causes said series of gears to apply gross rotational motion to said at least one ultrasonic transducer. - View Dependent Claims (16, 17, 18, 19, 20)
