摘要:
An endoscope includes a handle connected to a flexible, steerable, kink-resistant insertion tube. An endoscope insertion tube may include a shaft, a lower durometer section proximate to a distal end of the shaft, and a higher durometer section positioned between the lower durometer section and a medium durometer section. The endoscope insertion tube may further include a fourth thermoplastic laminate section proximate to a proximal end of the shaft and having a higher durometer. A method of making an endoscope insertion tube may include inserting a mandrel with one, two, or more lateral slots and a liner into a shaft, wherein the liner is positioned between the mandrel and the shaft, bonding a bonded portion of the liner to an inner surface of the shaft, separating other portion(s) of the liner from the shaft, and inserting a first deflection wire in a gap between the shaft and the unbonded portion(s) of the liner.
