Tissue specimen retrieval bag, method for retrieving tissue
View Patent ↗Provided is a tissue retrieval bag. The bag is made primarily of a first material, the bag having a region defining an opening; a pleated fold intersecting the opening. The bag has at least one porthole on at least one side of the bag. The at least one porthole is covered by a second material, the second material being different from the first material. The bag also includes a first hem circumferentially formed around the opening, the first hem forming insertion points adapted to receive a first draw string.
1. A tissue retrieval bag, wherein the bag is made primarily of a first material, the bag comprising:
a region of the bag defining an opening;
a pleated fold intersecting said opening;
at least one porthole on at least one side of the bag, wherein the at least one porthole is covered by a second material, the second material being different from the first material, wherein the first material is rip-stop nylon and the second material is polyurethane; and
a first hem circumferentially formed around said opening, said first hem forming insertion points adapted to receive a first draw string.
2. The bag as recited in claim 1 , further comprising a second hem circumferentially formed around said opening, said second hem forming insertion points adapted to receive a second draw string and said second hem being located inferior to said first hem.
3. The bag as recited in claim 1 , wherein the porthole has a diameter of between 3 and 20 mm.
4. The bag as recited in claim 1 wherein the fold is restricted to a distal-most region of said opening.
5. The bag as recited in claim 1 wherein the fold is restricted to a part of the opening opposite the insertion points.
6. The bag as recited in claim 1 wherein the bag opening remains open once the bag is unfolded.
7. The bag as recited in claim 1 wherein the opening has a diamond-shaped cross section.
8. The bag as recited in claim 1 further comprising a means for deploying the fold from a medially directed to a laterally directed configuration.
9. The bag as recited in claim 1 further comprising a proximal longitudinal side in opposition to the pleated fold, a portion of that proximal longitudinal side reinforced so as to receive a means for manipulating the bag.
10. The bag as recited in claim 9 , wherein the portion is formed into a generally planar region adapted to receive a grabbing tool.
11. The bag as recited in claim 1 , further comprising a plurality of looped tabs on an exterior surface of the bag.
12. A tissue retrieval bag, wherein the bag is made primarily of a first material, the bag comprising:
a region of the bag defining an opening;
a pleated fold intersecting said opening;
at least one porthole on at least one side of the bag, wherein the at least one porthole is covered by a second material, the second material being different from the first material;
a first hem circumferentially formed around said opening, said first hem forming insertion points adapted to receive a first draw string; and
wherein the bag comprises luminescent regions that emit light when illuminated by a light inserted in the patient.
13. A tissue retrieval bag, wherein the bag is made primarily of a first material, the bag comprising:
a region of the bag defining an opening;
a pleated fold intersecting said opening;
at least one porthole on at least one side of the bag, wherein the at least one porthole is covered by a second material, the second material being different from the first material;
a first hem circumferentially formed around said opening, said first hem forming insertion points adapted to receive a first draw string; and
a proximal longitudinal side in opposition to the pleated fold, a portion of that proximal longitudinal side reinforced so as to receive a means for manipulating the bag, wherein the portion is formed into a pocket and the manipulating means is a blunt probe.
