Abstract
A handheld surgical endoscope has a disposable, single-use portion that includes a and a re-usable portion that includes a handle and display module. The distal tip includes LED illumination and an imaging module that feeds live video to the display module. The imaging module includes a lens system of no more than two lenses and provides the imaging module with a field of view greater than 120 degrees, preferably 130 degrees or more, and most preferably 140 degrees or more. LED illumination is provided by plural LED arranged symmetrically around an optical axis to provide a field of illumination that substantially coincides with the field of view of an imaging module. An image brightness balance arrangement selectively varies the illumination provided by different LEDs to reduce brightness differences between different areas of the displayed images.
