Abstract
A tissue bag for surrounding tissue (2) during a surgical procedure comprises a bag body (6) capable of forming an enclosure, an opening (9) in the bag body, and one or more inflatable ribs (8) located on the bag body. The ribs (8) are such that inflation of the one or more ribs to a first extent causes the bag to deploy to an open position in which the bag is capable of being placed over tissue with the tissue received through the opening. Inflation of the one or more ribs (8) to a second further extent causes the bag to envelop the tissue with the opening (9) being smaller in diameter than in the open position. The ribs may each include at least first and second discrete longitudinal portions (10), (11) with an angled end face (15) therebetween.
Claims23
A tissue bag for surrounding tissue during a surgical procedure, the tissue bag comprising:
- a bag body capable of forming an enclosure;
- an opening in the bag body;
- and
- a first inflatable rib including a first tip and a second inflatable rib including a second tip located on the bag body, the first tip being spaced from the second tip by a first distance,
- wherein:
- inflation of the first and the second inflatable ribs to a first extent causes the bag to deploy to an open position in which the bag is capable of being placed over tissue with the tissue received through the opening, and
- inflation of the first and the second inflatable ribs to a second further extent causes the bag to envelop the tissue with the opening being smaller in diameter than in the open position and the first tip to be spaced from the second tip by a second distance that is shorter than the first distance.
A method of encapsulating tissue for surgical purposes comprising:
- introducing a tissue bag into the body of a patient, the tissue bag including:
- a bag body capable of forming an enclosure,
- an opening in the bag body, and
- a first inflatable rib including a first tip and a second inflatable rib including a second tip located on the bag body, the first tip being spaced from the second tip by a first distance;
- inflating the first inflatable rib and the second inflatable rib to a first extent such that the bag deploys to an open position;
- placing the bag over the tissue to be enclosed, with the tissue being received through the opening;
- and
- further inflating the first and the second inflatable ribs to a greater extent such that the first tip is spaced from the second tip by a second distance that is shorter than the first distance and the bag envelops the tissue with the opening being smaller in diameter than in the open position.
A method of morcellating a uterus, comprising:
- introducing a tissue bag into the body of a patient, the tissue bag including a bag body capable of forming an enclosure, an opening in the bag body, and a first inflatable rib including a first tip and a second inflatable rib including a second tip located on the bag body, the first tip being spaced from the second tip by a first distance;
- inflating the first and the second inflatable ribs to a first extent such that the bag deploys to an open position;
- placing the bag over the uterus, with the uterus being received through the opening;
- iv) further inflating the first and the second inflatable ribs to a greater extent such that the first tip is spaced from the second tip by a second distance that is shorter than the first distance and the bag envelops the uterus with the opening being smaller in diameter than in the open position;
- and
- morcellating the uterus within the tissue bag.
