ABSTRACT:
A joint mechanism for connection between a sheath and a manipulating section of an endoscopic treatment instrument is provided. A joint includes a leading end portion connected to said sheath, and an expanded base end portion having a first cross sectional shape. A receptacle ring is mounted on an leading end portion of said manipulating section and rotatable within a predetermined angular range relative to said leading end portion of said manipulating section. The receptacle ring is formed with an insertion hole having such a second cross section as to permit said expanded base end portion to be passed therethrough. A fitting hole is formed in said leading end portion of said manipulating section so as to non-rotatably receiving said expanded base end portion that has been passed through the insertion hole. By rotating said receptacle ring in a state that said expanded base end portion has been passed through said insertion hole and fitted in said fitting hole, said insertion hole is oriented to inhibit passage of said expanded base end portion therethrough, thereby non-removably connect said joint to said leading end portion of said manipulating section.
