Abstract: 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.

Abstract: 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.

Abstract: A duodenoscope protected with disposable consumables is provided. An insertion portion of a duodenoscope body (1) is covered with a cuff (3). A disposable forceps passage tube (4) is inserted into a tube of the duodenoscope body (1). A distal end of the duodenoscope body (1) is covered with an end cap (2) which is integrally connected to the cuff (3) and the disposable forceps passage tube (4). An elongated opening (2.1), which is of the same shape as the opening of a head end (1.1) of the duodenoscope body (1), is formed in a side face of the end cap (2). A forceps-lifting unit (1.2) is disposed in the head end (1.1) of the duodenoscope body (1). The end cap (2) is made of a transparent elastic material. A soft connection port (5) is disposed in the elongated opening (2.1) of the end cap (2). The soft connection port (5) is shaped like a smoking pipe and made of an elastic film. A large-orifice end of the soft connection port (5) is glued to the elongated opening (2.

Abstract: A sheathed endoscope, includes: an endoscope and a disposable component. The disposable compartment protects the inner and outer surfaces of the endoscope. The disposable compartment includes: a cap of endoscope tip in the distal end of endoscope, a disposable tube for biopsy forceps, and an outside sheath capsule for endoscope shaft. The tip cap connects the sheath capsule and the disposable tube for biopsy forceps. There are multiple windows set on the lateral side of endoscope tip, wherein pills containing transparent fluid are placed somewhere in between of the tip cap and the distal end of endoscope. The pills will be crushed by co-fraction of the tip cap and the distal end of endoscope, to release the transparent fluid to fill in the space formed between the tip cap and the distal end of the endoscope.

Abstract: A disposable protecting cover for an endoscope, the endoscope comprising a endoscope and a disposable valve disk, and the disposable protecting cover comprising a disposable sheath, a clamping tube, a disposable suction tube, a three-way sealing cap, a water air tube, and a protecting cover comprising a hand entrance and an instrument insertion opening.

Abstract: The purpose of this invention is absolute elimination of medical cross-infection by endoscopy. It offers an endoscope system with a disposal sheath. The disposal sheath via anterior end cap connects the capsule which covers the outside of the endoscope and the disposal channel which sheathe in the endoscope channel and the fluid-air channel, and all these parts are joined together in a whole body. After the disposal channel is passed through the endoscope channel, its posterior disposal channel can be blocked into the elastic sealing cap via the guide tube, the posterior disposal channel's orifice need to be heated and melted and cut up simultaneously and its cut edge is in shape of V-shape by using one kind of heat fusion forceps after the use and before the retracting from the endoscope channel.
