INTENSITY CONTROLLABLE HAND-HELD SURGICAL LIGHT

摘要

A hand held surgical light assembly (10) is provided with a light source (22), a handpiece (12) which is adapted to be grasped, and manipulated by a user. The handpiece (12) has a light guide (16) with a proximal end optically connected to the light source (22), and a distal end which projects outwardly from said handpiece so as to direct light guided thereby onto a field of view determined by manipulation of the handpiece by the user. The handpiece includes a switch assembly (70) which is operatively coupled to the light source (22) to allow user selection between at least two different light intensities (e.g., essentially on/off) discharged by said light guide (16) onto the field of view. In preferred forms, the switch assembly (70) includes an electrically conductive inner core (70)(72), and an electrically conductive outer tubular elastomeric member (70)(71) concentrically positioned in the surrounding, but spaced relationship, with the inner base.
