摘要： A tubular connector for use with a spiral tube used on an insertion section of an endoscope. The tubular connector including: an outer surface; an inner surface; and a plurality of cams circumferentially spaced on the inner surface to project radially inward from the inner surface, the plurality of cams extending in a longitudinal direction of the tubular connector; wherein each of the plurality of cams have one or more cam surfaces configured to engage a rotating member to rotate the spiral tube. The plurality of cams can alternatively be formed directly on an interior surface of the spiral tube.

摘要： A polymeric device including: an elongated hollow tube having an outer surface; and a spiral fin wound around the outer surface of the hollow tube; wherein the hollow tube and the spiral fin are formed of a single unitary piece through a molding process. The polymeric device can further include a longitudinal projection projecting from the outer surface of the hollow tube, the longitudinal projection having a greater thickness than other portions of the hollow tube and the longitudinal projection extending at least a portion of a longitudinal length of the hollow tube.
