  • Handgrip for an electro-optical diagnostic apparatus set
    Patent number: 5542904
    Abstract: A handgrip for an electro-optical diagnostic-device set comprises a tubularly-shaped battery housing (10) for receiving variously-shaped energy sources (31, 33, 36, 38) therein to energize a lamp of an instrument head at a second end of the tubularly-shaped battery housing. There is a set of releasable end covers 40 for an opposite, first, end of the tubularly-shaped battery housing, with each of the end covers having a substantially identical cover attaching element (42) as that of the other end covers for mating with an opposite housing attaching element of the housing, but with each end cover being shaped differently from the other end covers, so as to accommodate an energy source different from energy sources accommodated by the other end covers.
