Tube connection structure in endoscope

摘要

A tip component is provided at an extremity of an insertion part of an endoscope. The tip component includes a body member, in which a forceps aperture is formed. A forceps tube is arranged inside the insertion part. A hard part is formed at the end of the forceps tube, at which the forceps tube is sandwiched between an inner cylinder and an outer cylinder. The hard part is inserted into the forceps aperture of the body of the tip component and is fixed with a screw. A connecting part between the forceps tube and the forceps aperture is thus formed in the body of the tip component, and the length of the tip component is reduced as a result.
