12. The tissue receiving bag according to claim 10 , wherein the free end of a least one of the flexible tubes is closed, at least prior to use of the bag, by at least one of a tube portion, a closure or a valve.

13. The tissue receiving bag according to claim 10 , wherein the at least one further opening or additional further opening comprises a closure or a seal for sealing around an instrument inserted through said at least one further opening or additional further opening.

14. A tissue receiving bag for use in surgery, wherein the bag comprises, upon insertion into a human or an animal body, at least one tissue receiving opening for receiving tissue or an instrument opening, wherein the bag further comprises, upon insertion into the human or the animal body, at least one further opening into the bag, wherein a flexible tube extends from said at least one further opening having a free end comprising an insertion opening for inserting an instrument into the bag, wherein a further tube extends from or defines the instrument opening, said further tube comprising a closure or seal for closing or sealing the further tube around an instrument extending through said further tube or for closing the further tube when said instrument is retracted from said instrument opening.

15. An operating set for surgery, comprising a tissue receiving bag according to claim 14 , and at least one morcellator instrument, wherein at least one of the bag or the at least one morcellator instrument comprise at least one detector and indicator system for preventing the morcellator instrument from puncturing the bag.

16. The operating set according to claim 15 , further comprising at least one further instrument insertable through at least one of the flexible tube or the at least one further opening of the bag, wherein at least one of the at least one further opening or the flexible tube can be sealingly closed around said at least one further instrument when extending through at least one of said flexible tube or at least one further opening, wherein the at least one further instrument is one of an endoscope, a camera, a catheter, a cannula, tongs, or scissors.

17. The tissue receiving bag according to claim 14 , wherein the bag has the at least one tissue receiving opening and the instrument opening, and wherein the instrument opening is spaced apart from the at least one tissue receiving opening.
