ABSTRACT:
An end plug or fitting for an endoscope includes a mouthpiece member 1 having a central passage therethrough for the insertion of a medical instrument, such as a forceps, into a guide tube 5. The upper portion of the passage receives a sealing member 2 having a nozzle section 2a whose oblique end face confronts the mouth of a suction pipe 4 and whose inner diameter is smaller than that of the guide tube and approximately the same as the outer diameter of the instrument(s) to be inserted. Such a construction provides for ease of instrument insertion and withdrawal, good suction during insertion, and very low suction after withdrawal.
