Abstract:
1. A veterinary otoscope permitting examination of an ear, said veterinary otoscope comprising: i. An instrument head including a proximal end and a substantially conical shaped distal insertion portion; ii. A viewing means proximate to said proximal end of said instrumentation head; iii. A tip element releasably attached in overlaying relation onto said distal insertion portion, said tip element including a substantially conical body and a distal tip opening and in which said distal insertion portion and an attached tip element are each insertable into the ear of a patient; iv. An imaging lens train disposed within said instrument head, each of said imaging lens train, said viewing means, distal opening of said insertion portion and the tip opening of an attached tip element being aligned along an optical axis; v. A focusing mechanism for moving said viewing means relative to said imaging lens train along said optical axis; and vi. An entrance pupil located distal to the distal opening of the distal insertion portion of said instrument head, but proximal to the distal opening of said attached tip element to permit substantially the entire tympanic membrane to be viewed at once by said viewing means without vignetting by the distal tip opening of said distal insertion portion.
