Abstract:
A powered surgical handpiece, said handpiece comprising:a housing, said housing have an outer surface and an opening that is formed in the outer surface that defines a wiring space in said housing, the wiring space being defined by a perimeter section of the outer surface of said housing; a surgical implement that extends from said housing, said surgical implement being selectively actuated based on application of a variable control signal; a circuit board fixedly mounted in the wiring space of said housing, said circuit board having an outwardly directed surface and a plurality of conductive traces formed on the outwardly directed surface so as to define a contact pad; a flange fixedly disposed in the wiring space of said housing, said flange positioned to circumferentially surround said circuit board and positioned to be spaced inwardly of the perimeter section of the outer surface of said housing; and a web formed of elastomeric material that is mounted to said housing, said web having: a base positioned in the opening of said housing, said base having an outer edge; a lip that extends circumferentially around and away form the outer edge of said base, said lip positioned to be located between the perimeter section of the outer surface of said housing and said flange, said lip being dimensioned to be compression fitted between the outer surface of said housing and said flange; a button formed integrally with said base so that said button flexes relative to surrounding portions of said base, wherein said button is positioned to be located over said contact pad and is constructed so that, upon depression of said button, said button abuts said contact pad; and a landing pad located on an undersurface of said button that is directed towards said contact pad and is positioned, so that, when said button abuts said contact pad, said landing pad abuts said contact pad, said landing pad having a layer of conductive material thereon, so that, when said landing pad abuts said contact pad, the conductive material establishes a conductive path between said conductive traces.
