摘要： A flexible tube for use in an endoscope comprises a flexible basic tubular core structure including an outer meshwork tube, and a thermoplastic synthetic resin tube bonded to the outer meshwork tube of the tubular core structure in a manner such that the resin tube maintains an inherent compressive pre-stress in the finished flexible tube. An endoscope tube having flexibility which varies in a step-wise manner from one end of the tube to the other is obtained by integrally bonding two or more thermoplastic synthetic resin tube sections formed of respective resin materials having different hardnesses to the outer surface of the tubular core structure to form a coating layer in an analogous manner. The ends of adjacent tube sections substantially abut each other and upon heating the tube sections to a temperature only slightly higher than a softening point but lower than a melting point of any one of them, the localized regions of the respective pairs of abutting tube section ends are heated to a temperature which is as close as possible to a melting point of one of the tube sections having a higher melting point than that of the other tube section, whereby the end of the other tube section having a lower melting point is fused with the end of the adjacent tube section, and after cooling of the tube sections, a continuous and integral tube is obtained without any joints or junctures.

摘要： A cover device which is removably fitted over an endoscope to cover an insert part of the endoscope and a control part connected to the proximal end of the insert part. The cover device includes a tubular sheath for covering the insert part so as to isolate it form the outside, and a control part cover for wrapping the control part. The control part cover is separate from the sheath and spreadably provided in contiguity with the proximal end of the sheath. In addition, a fluid supply tube is disposed such that one end portion of the tube extends through the sheath to communicate with the distal end of the sheath. The other end portion of the tube extends from the proximal end of the sheath along the outside of the control part cover.

摘要： A flexible tube for use in an endoscope comprises a flexible basic tubular core structure and a homogeneous thermoplastic synthetic resin tube bonded to the outer surface of the tubular core structure to form a coating layer by positioning the synthetic resin tube tightly over the basic tubular core structure with a contact pressure therebetween and heating the synthetic resin tube to a temperature higher than a softening point of the thermoplastic synthetic resin forming the same. A flexible tube having flexibility which varies in a step-wise manner from one end of the tube to the other is obtained by integrally bonding as a whole two or more homogeneous thermoplastic synthetic resin tube sections formed of respective resin materials having different hardnesses to the outer surface of the tubular core structure to form a coating layer in an analogous manner. The ends of adjacent tube sections substantially abut each other and upon heating the tube sections to a temperature higher than a softening point of any one of them, the regions of the respective pairs of abutting tube section ends are heated to a temperature substantially near a melting point of the tube section having the higher melting point to successively fuse the respective pairs of abutting tube section ends together.

摘要： A distal end part of an endoscope having a viewing window for introducing light from an object into an objective optical system for forming an observed image. An illuminating window is disposed in a side by a side relationship with the viewing window for illuminating a visual field of the objective optical system. A continuous transparent cover covers the surfaces of both the illuminating and viewing windows. A window glass is attached to the viewing window in such a manner that a virtual image of the outer edge portion of the window glass, which is produced by single reflection from the inner side of the outer surface of the transparent cover, lies outside the visual filed of the objective optical system.
