ENDOSCOPE WITH WIRELESS LENS MODULE ADD-ON

摘要

An endoscope that may be used with a wireless lens module that can be attached to an insertion end of the endoscope. The endoscope comprises a hollow elongate tube extending from a handle end to the insertion end of the endoscope for insertion into the body of a patient. A mechanical connector at the insertion end of the endoscope allows for at times attaching the lens module at the insertion end of the endoscope and also for disconnecting the lens module form the endoscope. One or more wireless electrical elements at the insertion end of the endoscope provides wireless electrical power to the lens module. The lens module includes one or more fixed position lenses aligned along the axis of a light path; and one or more electrically-operated, actively-adjustable lens aligned along the axis of a light path. A mechanical connector of the lens module allows the module to be attached in a fixed position at the insertion end of the endoscope. The module includes one or more wireless electrical elements for receiving wireless electrical power from the inductor at the insertion end of the endoscope for operating the actively-adjustable lens. Either the lens module or the endoscope includes an light sensor aligned along the axis of a light path for converting focused light into electronic image signals.
