    摘要： The present invention is directed to a surgical otoscope for examining and operating upon the external ear canal and tympanum. The surgical otoscope comprises an optical diagnostic instrument and an adapter member attached thereto. An image conveyer and a light transmitter are located within the optical-diagnostic instrument and extend therefrom and into the adapter member. The adapter member includes extendable and retractable surgical instrumentation and a suction tube. The combination of optical diagnostic and surgical instrumentation in the same device a enables a physician to simultaneously examine and operate upon the external ear canal and tympanum. Accordingly, the physician may selectively use the instruments while viewing the areas to be examined or operated upon through the same device.

    摘要： A human powered wheeled land vehicle is disclosed. The vehicle may utilize two or more wheels, including at least one driving wheel and one steering wheel. The vehicle is propelled by use of at least one lever which is positioned such that the operator is able to grasp the lever and move it back and forth perpendicularly to his body in a reciprocating fashion. A drivetrain mechanism translates the reciprocating motion of the lever into rotational motion of the driving wheel. Two levers may preferably be provided so as to allow the operator to provide alternating motion of the levers. A steering handle is provided on at least one of the levers to control the direction of the steering wheel. The operator may preferably be secured to a seat, the seat also having a back rest, while operating the vehicle. The invention has particular application for use as a racing or touring wheelchair when operated by a paraplegic or a lower-limb amputee.
