Abstract

The rectoscope comprises a short, wide tube having a proximal coupling housing or a coupling housing which may be coupled at its distal side to a tube of optional length and width. The coupling housing may be coupled at its proximal side to a mandrel or an instrument carrier which is equipped with axially parallel through-bores, for sealed traversal by an optical system and auxiliary instruments. The tube is rigidly connected to an operating table or the like by means of a handle. Passages through which an inert gas may be introduced into the rectum under pressure lead into the rectoscope through the handle or separately. Vapors impeding the view which are developed in the rectal cavity during a coagulating operation may either be discharged direct into the atmosphere via a separate passage or retained in a reception vessel, together with quantities of fluid or body secretions drawn off by suction via a flushing and suction tube inserted into the rectal cavity, by means of a filter preconnected to a gas return pipe.
