Patent ID: 10405839

Abstract:
A minimally-invasive tissue retrieval device includes a flexible, liquid-impermeable bag with wires attached to the interior surface by an attachment mechanism that releases the wires when pulled. The wires extend into the bag from opposing sides of the bag opening, down to the bottom of the bag. Ends of the wires extend vertically upward out of the opening and are attachable to a wire retracting element rotatably attached to a housing, such that rotation of the retracting element relative to the housing winds the wires about the retracting element, pulling them away from the interior surface, and upward towards the opening. The bag is insertable into a surgical cavity, where a tissue sample is inserted into the bag. Rotatably-retracting the wires cuts through the tissue, which can then be removed in sections through the opening positioned outside the surgical cavity to prevent the spread of tissue fragments.
