Abstract
A tissue retrieval arrangement for enclosably retrieving body tissue from a mammalian body cavity. The retrieval arrangement comprises an elongated thin walled sheath-like retrieval bag having a proximal end and a distal end. A plurality of receiving tips are arranged on the distal end of the sheath to permit receipt of a grasper jaw in each of the receiving tips and thus permit safe retrieval of a body tissue between the receiving tips when moved by the grasper jaws. The bag is everted over the severed tissue once the receiving tips have grasped the tissue, and the now enclosed tissue and bag may be safely removed from the patient.
Claims18
A tissue retrieval arrangement for enclosably retrieving body tissue from a mammalian body cavity comprising:
- an elongated thin walled sheath-like retrieval bag having a proximal end and a distal end;
- an arrangement of receiving tips on said distal end of said sheath to permit receipt of a grasper jaw in each of said receiving tips and thus permit safe retrieval of a body tissue between said receiving tips moved by said grasper jaws therewithin.
A method of retrieving body tissue from a body cavity of a mammalian patient comprising:
- placing an elongated grasper device with a jaw arranged on a distal end thereof into an elongated tissue retrieval bag having a proximal end and a distal end, said retrieval bag having receiving tips on said distal end thereof to receive said jaws respectively therein;
- severing a tissue from a body portion of the patient;
- grasping said tissue by manipulating said jaws and said receiving tips onto said tissue;
- everting said retrieval bag about said tissue;
- and
- withdrawing said retrieval bag with said tissue now inside, from said body cavity of the patient.
A method of retrieving body tissue from a body cavity of a mammalian patient comprising:
- placing an elongated grasper device with a jaw arranged on a distal end thereof into an elongated tissue retrieval bag having a proximal end and a distal end, said retrieval bag having receiving tips on said distal end thereof to receive said jaws respectively therein as said grasper is inserted into said bag;
- severing a tissue from a body portion of the patient;
- grasping said tissue by manipulating said jaws and said receiving tips onto said tissue;
- pulling on said proximal end of said retrieval bag to evert said bag about said tissue being grasped;
- and
- withdrawing said retrieval bag with said tissue now in said everted bag, from said body cavity of the patient.
