A collection bag for better isolating and removing a large mass of tissue from a female patient's abdominal cavity during a laparoscopic surgery includes: (a) a flexible and resilient ring that has a configuration adapted to: (i) enable it to be distorted so that it can be vaginally inserted into the patient's abdominal cavity and then quickly return to essentially the same shape that it took prior to being deformed, (ii) size the ring's open area so that the large tissue mass can pass though it, and (iii) be further distorted so that it can be removed from the abdominal cavity through a laparoscopic-surgery-appropriate incision in the wall of the abdominal cavity, and (b) a sleeve having a flexible wall, an open end, and a defined interior volume, and wherein the sleeve's open end is affixed to the ring, and its interior volume is sized to allow the excised tissue to reside and be isolated within the bag's sleeve. |

1. A bag for improved isolation and removal of a large mass of tissue from a female patient's abdominal cavity during a laparoscopic surgery, said bag comprising:
a flexible and resilient ring having a circumference that encloses a specified ring open area, said ring having a configuration adapted to enable: (i) said ring to be distorted so that said entire ring can be vaginally inserted to gain access for said entire bag into the abdominal cavity of said patient, (ii) the sizing of said specified ring open area is such that said large mass of tissue can pass through said ring open area, and (iii) said entire ring to be removed from the abdominal cavity of said patient through a laparoscopic-surgery-appropriately-sized incision in the abdominal wall of said abdominal cavity, a sleeve having a flexible wall and open and closed ends between which said wall encloses and defines an interior volume of said sleeve, wherein said sleeve open end is affixed to said ring, and said sleeve interior volume is sized so as to allow said large mass of tissue, after passing through said ring open area, to reside within and be isolated in the said sleeve, and wherein to provide for said vaginal insertion of said ring, said ring is dimensioned such that the cross-sectional section through said ring has a cross-sectional area in the range of 0.3-1 cm2. |
