Duodenoscope protected with disposable consumables
A duodenoscope protected with disposable consumables comprises a body having an insertion portion covered with a cuff, and a disposable forceps passage tube inserted into a tube of the body. A distal end portion of the body is covered with an end cap, which is integrally connected to the cuff and to the disposable forceps passage tube. The end cap is made of transparent elastic material with an elongated opening, compatible in shape to an opening of the distal end portion of the duodenoscope body, and further comprises a soft connection port in a shape of a pipe with a small-orifice end secured onto the disposable forceps passage tube, and a large orifice end secured onto an edge of the elongated opening. A forceps-lifting unit is disposed at the distal end portion of the duodenoscope body, and comprises a grooved pulley coupled with a steel wire for maneuverability.

The present disclosure is for an endoscope assembly comprising an endoscope and a disposable sheath cover. The endoscope comprises an illumination window adjacent to an observation window situated along a lateral side of a distal end portion, and an elongated slot to accommodate biopsy instruments. The sheath further comprises an end cap fitted around the end portion of the endoscope with a capsule secured to its inner wall. When the end cap engages the endoscope, the capsule is ruptured to release a transparent liquid immersing the illumination window and the observation window. A soft connector is bonded to the end cap covering the elongated slot, and to an outer surface of a biopsy channel. The soft connector further comprises an opening allowing the biopsy channel to pass through. The sheath can accommodate air/water tubes, and is secured onto the shaft of the endoscope via a cuff.
