Rectoscope
First Claim
1. Rectoscope for examination of the rectum and for intestinal surgery, comprising a short, wide tube equipped proximally with a coupling housing having means for connecting selectively to a mandrel for expanding the sphincter to the diameter of the tube and to an instrument carrier comprising axially parallel bores, an optical system for insertion into one of the bores and a needle holder and a sealing element for insertion into another of the bores, means for sealing said optical system, needle holder and sealing element in its associated bore, said sealing element comprising a cylinder portion associated with means for locking it, bayonet-fashion in a bore, said cylinder portion having joined to its proximal extremity a gas tight elastic extension which is closed off proximally by a sealing cap, auxiliary instruments being insertible through said extension and the tube into the rectum which may be inflated by means of a gas.

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.
