A method of morcellating a targeted piece of tissue in a subject comprising:
- a) providing a collapsible and expandable receptacle, having a vertical axis with a lower half section with a distal area, and an upper half section with a proximal end, and a horizontal axis, configured such that when the collapsible receptacle is collapsed on its horizontal axis, it is linearly sized to fit within and through an opening between 14-20 mm in width but not when expanded in a natural open position;
- said receptacle comprising:
- a plurality of at least three support rods positioned in a circumferential and equidistant manner around the vertical axis, or substantially so, having distal ends coupled to the distal area of the receptacle and having proximal ends extending proximally and laterally away from the distal area and configured to have natural spring tension such that the support rods are expanded, away from each other in a natural, open, position, and move towards each other on the horizontal axis when the receptacle is collapsing and move away from each other on the horizontal axis when the receptacle is opening,
- a flexible liner that is water resistant, low-friction, tear-resistant, and made of material different from the support rods, having a thickness between 0.05-0.15 mm, wrapped along the support rods such as to define a bag with a closed end at the distal area;
- and a cover made of a thin flexible material that is permanently attached to a perimeter of the proximal end of the receptacle, such that the cover and the perimeter of the proximal end of the receptacle are expandable and collapsible to fit through the 14 to 20 mm opening and the cover establishes a surface area having a plurality of premade holes configured to allow a trocar sleeve to pass through into the receptacle along the vertical axis when the receptacle is in a natural expanded position, and wherein the cover comprises a substantially central opening configured to be releasably closable, such that at least 75% of area of the substantially central opening is occluded, while the perimeter of the proximal end of the receptacle is maintained in its expanded natural, open position, and the plurality of premade holes individually remain accessible for the trocar sleeve to pass through into the receptacle along the vertical, axis;
- b) creating one or more incisions in the subject near the targeted piece of tissue, wherein the incision has a width of between 14-20 mm and inserting a first trocar sleeve into a first incision;
- c) collapsing the receptacle;
- d) inserting the collapsed receptacle inside of the subject through the first trocar sleeve;
- e) positioning the targeted tissue into the receptacle through the substantially central opening in the cover;
- f) closing the substantially central opening such that at least 75% of the opening's area is occluded;
- g) positioning a morcellator into the receptacle and cutting the target tissue;
- h) removing the cut targeted tissue from the receptacle through a trocar sleeve;
- and
- i) collapsing the receptacle and withdrawing it from inside the subject through a trocar sleeve.
