Surgical Head Mirrors
Aranzi was the first to use a light source for an endoscopic procedure,
focusing sunlight through a flask of water and projecting the light into the
nasal cavity
Philip Bozzini, built an instrument that could be introduced in the human
body to visualize the internal organs. He called this instrument "LICHTLEITER".
Bozzini used an aluminium tube to visualize the genitourinary tract. The
tube, illuminated by a wax candle, had fitted mirror to reflect images.
Dimitri Ott, wore headband mirror to reflect light and augment
visualization and used access technique in which a speculum was introduced
through an incision in the prior vaginal fornix.
