Abstract
A light scanning device has a tip structure which includes a light scanning part connected to a light source, and which is insertable into a body cavity and is formed so as to be water-tight. A controlling part controls the light scan through the tip structure, and the tip structure and the controlling part are also connected to each other in a water-tight manner by a slender tube through which a plurality of electrical cables pass. An electric connector is fixed with the proximal end portion of the tube in a water-tight manner, and is electrically connectable so as to be water-tight with and removable from this controlling part.
