FLEXIBLE TUBE OF ENDOSCOPE AND METHOD OF PRODUCING THE SAME

摘要

A long and thin flexible tube of an endoscope which forms an outer wall of an insert part and which is fitted with a built-in object including a device for transmitting an observed image from the distal end of the insert part to the proximal end thereof. Also disclosed is a method of producing the long and thin flexible tube. The flexible tube is formed by inserting the built-in object into a plurality of short flexible tube elements, and then connecting together each pair of adjacent short flexible tube elements by use of a connecting device, with the built-in object inserted therein.
