Tissue removal containment systems

Abstract

The tissue removal containment system is provided that includes a tissue removal and/or containment bag arranged to be inserted through an opening into a confined space. The bag has a support or ring having a compressed, partially compressed and/or uncompressed state or position. The bag can also include an enclosure or film defining the enclosure connected to the support with the enclosure having a confined state and a deployed or unconfined state.

1 . A tissue containment bag comprising:
 a ring having an inner periphery delimiting an open end, the ring being deformable from an uncompressed state in which the open end delimited by the ring is unobstructed to a compressed state in which the open end delimited by the ring is partially obstructed;   a film heat-sealed to the ring to form an enclosure having an interior and a closed end, the interior of the enclosure being accessible through the open end delimited by the ring, the film and the interior of the enclosure being extendable to a deployed state in which a distalmost end of the film extends away from the ring from a confined state in which the film including the distalmost end is confined to a position adjacent to ring; and   a strap connected and encircling the ring and a portion of the film, with the strap being textured relative to a smooth outer surface of the film, the strap having a fastened state in which the strap in the fastened state secures the ring in the compressed state and, simultaneously, the film in the confined state.   
     
     
         2 . The tissue containment bag of  claim 1  wherein the strap is heat-sealed to itself connecting the strap to the ring and the film. 
     
     
         3 . The tissue containment bag of  claim 1  wherein the strap has an unfastened state in which the strap simultaneously releases the ring from its compressed state and the film from its confined state. 
     
     
         4 . The tissue containment bag of  claim 3  wherein the strap comprises a fastener attachment to releasably attach the strap from the fastened state to the unfastened state. 
     
     
         5 . The tissue containment bag of  claim 4  wherein the inner periphery of the ring has a diameter and the strap has a length greater than the diameter of the inner periphery of the ring. 
     
     
         6 . The tissue containment bag of  claim 5  wherein the strap has an outer surface and an inner surface and the fastener attachment comprises a connector and a receiver disposed on the inner surface of the strap, the connector being disposed near a first end of the strap and the receiver being disposed near a second end of the strap. 
     
     
         7 . The tissue containment bag of  claim 6  wherein the first end of the strap is connected to the ring and the second end of the strap is not connected to the ring. 
     
     
         8 . The tissue containment bag of  claim 6  wherein the second end of the strap is connected to the ring and the first end of the strap is not connected to the ring. 
     
     
         9 . The tissue containment bag of  claim 6  further comprising a tab connected to the ring at a position opposite of the strap, the strap having a length longer than a length of the tab. 
     
     
         10 . The tissue containment bag of  claim 9  wherein the tab has a loop defining an opening through which the strap is threadable there through. 
     
     
         11 . The tissue containment bag of  claim 10  wherein, with the strap threaded through the loop, the ring is in a partially compressed state in which the open end delimited by the ring is obstructed, no longer unobstructed in its initial uncompressed state, and less obstructed than the ring in the compressed state. 
     
     
         12 . The tissue containment bag of  claim 11  wherein the loop of the tab has a diameter equal or greater than a width of the strap. 
     
     
         13 . The tissue containment bag of  claim 11  wherein the strap has a width greater than a diameter of the loop of the tab. 
     
     
         14 . The tissue containment bag of  claim 11  wherein the tab extends away from the ring and the strap extends away from the ring and the tab, the tab and strap being made of the same material. 
     
     
         15 . The tissue containment bag of  claim 11  further comprising a cord attached to the ring, the strap having a length shorter than a length of the cord. 
     
     
         16 . The tissue containment bag of  claim 15  further comprising a cinch attached to the film and disposed between the ring and the closed end, in which movement of the cinch away from the bag constricts the film, closing a pathway from the closed end of the film to the open end of the ring. 
     
     
         17 . A tissue removal containment system comprising:
 a tissue containment bag; and   a surgical instrument arranged to facilitate insertion of the tissue containment bag into a patient's body cavity, convert a ring of the tissue containment bag from a compressed state to an uncompressed state and a film of the tissue containment bag from a confined state to a deployed state, or convert the ring of the tissue containment bag from an uncompressed state to a partially compressed state.   
     
     
         18 . A method of removing a specimen with a tissue containment bag, the method comprising providing a tissue containment bag comprising a ring and a film connected to the ring, the film defining an enclosure;
 placing the ring in a compressed state and the film in a confined state;   securing the ring in its compressed state and the film in its confined state;   inserting the tissue containment bag into a patient's cavity with the ring in a compressed state and the film in a confined state;   releasing the film from its confined state to its deployed state and the ring from its compressed state to its uncompressed state;   placing a specimen through an opening defined by the ring in its uncompressed state and into the enclosure defined by the film in its deployed state;   partially closing the opening defined by the ring to secure the ring in a partially compressed state while the film remains in its deployed state;   removing the ring in its partially compressed state out of the patient's cavity with the film remaining within the patient's cavity;   releasing the ring from its partially compressed state to move to its uncompressed state; and   removing the specimen from the enclosure and out through the opening of the ring.   
     
     
         19 . The method of  claim 18  wherein the securing the ring in its compressed state and the film in its confined state further comprises wrapping a strap connected to the ring around portions of the ring and portions of the film and fastening the strap to itself and the releasing the film from its confined state to its deployed state and the ring from its compressed state to its uncompressed state further comprises unfastening the strap from itself. 
     
     
         20 . The method of  claim 19  wherein the partially closing the opening defined by the ring to secure the ring in a partially compressed state while the film remains in its deployed state further comprises threading the strap through a loop defined by a tab connected to the ring and pulling the strap through the loop to narrow the opening defined by the ring.
