Abstract: A bag for use in a laparoscopic surgery, having at its one end an opening through which extracted internal organ is put in and drawn from, and having at its other end a tubular organ storage portion with a closed bottom, of which bore diameter is smaller than that of the opening. The bag is characterized by being made of a soft synthetic resin, and its way part extending from the opening to the tubular organ storage portion being curved in a manner it intersects with the direction in which extracted internal organ is put in and drawn from at said opening.

Abstract: An endo-bag with an inflation-type receiving mouth comprising a flexible bag body having an organ receiving mouth provided with an inflation-type frame edge and an inserting portion for a surgical instrument such as forceps and laparoscope or the like. The inflation-type frame edge is provided with gores formed by three-dimensional tailoring and being so constructed as to be inflated and expanded to open said organ receiving mouth by pumping a fluid therein. The endo-bag can be easily and rapidly inflated and expanded to open the organ receiving mouth by pumping a fluid at low pressure and with small amount.
