Endoscope connector
First Claim
1. In an endoscope having an operation section;
- an illumination optical fiber bundle, a fluid-feeding tube and a suction tube extending from said operation section; and
endoscope connector connected to a console disposed externally of said endoscope and including a light source and a connection to an electric power source, said endoscope connector having a fluid-feeding fitting connected to said fluid-feeding tube and a suction fitting connected to said suction tube; and
a protection tube surrounding said illumination optical fiber bundle, said fluid-feeding tube and said suction tube and having two ends, one end thereof being connected to said endoscope connector and the other end thereof being connected to said operation section, the improvement wherein said endoscope connector comprises;
a socket member comprising a socket body having a generally cylindrical bore penetrating therethrough and having two ends and said fluid-feeding and suction fittings mounted on said socket body, said socket member being connected to said console at a portion of said socket body to which one of said two ends of said bore opens;
a generally cylindrically plug member rotatably and sealingly inserted in said socket body and having two ends, said plug member having said illumination optical fiber passing therethrough and allowing both said fluid-feeding tube and said suction tube to extend therein from one of said two ends of the plug member which is remote from said one of said two ends of said bore and to which said other end of said protection tube is connected; and
a pair of annular communication chambers defined between said socket body and said plug member to surround said plug member, one of said communication chambers being adapted to establish communication between said fluid-feeding fitting and said fluid-feeding tube and the other communication chamber being adapted to establish communication between said suction fitting and said suction tube, respectively.

Abstract
An endoscope connector comprises a socket member which has a cylindrical penetrating bore, that portion of said socket member at which one end of the penetrating bore is opened being connected to a console containing a light source and a connection for an electric source, and whose peripheral wall is provided with a fluid-feeding fitting and suction fitting; a cylindrical plug member which is sealingly inserted into the cylindrical penetrating bore of the socket member to rotate around the axis, receives the distal end portions of an illumination optical fiber bundle, fluid-feeding tube and suction tube extending from an endoscope, said plug member having one end which is near the other end of the socket member and to which the free end of a protection tube receiving the illumination optical fiber bundle, fluid-feeding tube and suction tube is fixed; and a pair of annular chambers which are formed between the surface of the cylindrical penetrating bore of the socket member and the peripheral surface of the plug member, and one of which communicates with the fluid-feeding fitting and fluid-feeding tube, and the other of which communicates with the suction fitting and suction tube.
