A surgical handpiece includes a housing having an interior cavity and an exterior surface adapted to be gripped by the hand of a user. A rotary drive mechanism is provided inside of the housing and includes a driven shaft with a passageway extending axially therethrough. A suction connection is provided on the housing as is a suction control mechanism operable between first and second operative positions for preventing suction from being applied to the passageway in the driven shaft when in a first operative position and for connecting suction to the passageway when in a second operative position.

A surgical tool (10) for chucking in a powered surgical handpiece, comprising an outer tubular member (11) with an opening (41) at the distal portion thereof. An inner tubular member (30) is movable in the outer tubular member and comprises a bendable inner tube (36) of flexible polymer material and a tissue working tip (40) extending forward from the distal end of the inner tube. The inner tube has a radially enlarged distal opening recess (62). The tip includes a reduced outside diameter, proximally extending, annular flange fixed within the inner tube distal recess (61). The annular flange of the tip is formed with hills and valleys (63, 64). The inner wall of the inner tube that defines the recess is formed with hills (65) that seat in the valleys of the annular flange so as to lock the tip to the inner tube. The annular flange is further shaped so as to extend into the recess a distance less than the overall length of the recess. Consequently, the inner tube immediately below the end of the annular flange has a section of reduced wall thickness.
