Specimen retrieval device
A specimen retrieval device includes a tubular body defining a longitudinal bore, an inner shaft slidably disposed within the longitudinal bore of the tubular body, and a specimen bag affixed to a support mechanism at the distal portion of the inner shaft. The specimen retrieval device includes a drain tube that passes from within specimen bags and out of the specimen retrieval device that permits passage of fluids out of the specimen bag prior to removal of the device from the body.
1. A specimen retrieval device, comprising:
a tubular body defining a longitudinal bore, the tubular body having a proximal portion, a distal portion, and a hand grip supported on the proximal portion of the tubular body;
an inner shaft having a proximal portion, a distal portion, an actuation handle supported on the proximal portion of the inner shaft, and a support member extending from a distal portion of the inner shaft;
a specimen bag supported on the support member at the distal portion of the inner shaft, the specimen bag including a body defining an opening; and
a drain tube defining a longitudinal bore, the drain tube having a proximal portion, a distal portion communicating with the interior of the body of the specimen bag, and pores at the distal portion of the drain tube.
2. The specimen retrieval device of claim 1 , wherein the support member includes a pair of resilient fingers which support the specimen bag and open the opening of the specimen bag in a deployed state.
3. The specimen retrieval device of claim 2 , wherein the resilient fingers are positioned adjacent the opening of the specimen bag.
4. The specimen retrieval device of claim 1 , wherein the specimen bag is furled about the inner shaft in a non-deployed state.
5. The specimen retrieval device of claim 1 , further comprising at least one pull string having a proximal portion and a distal portion encompassing the opening of the specimen bag, wherein the proximal portion of the pull string extends proximally from the actuation handle.
6. The specimen retrieval device of claim 5 , wherein the at least one pull string includes two pull strings.
7. The specimen retrieval device of claim 5 , wherein the proximal portion of each of the two pull strings extends proximally from the actuation handle.
8. The specimen retrieval device of claim 1 , wherein the drain tube passes through the longitudinal bore of the tubular body.
9. The specimen retrieval device of claim 8 , wherein the proximal portion of the drain tube extends from the proximal portion of the tubular body.
10. A specimen retrieval device, comprising:
a tubular body defining a longitudinal bore, the tubular body having a proximal portion, a distal portion, and a hand grip supported on the proximal portion of the tubular body;
an inner shaft having a proximal portion, a distal portion, an actuation handle supported on the proximal portion of the inner shaft, and a support member extending from a distal portion of the inner shaft;
a specimen bag supported on the support member at the distal portion of the inner shaft, the specimen bag including a body defining an opening;
at least one pull string having a proximal portion and a distal portion encompassing the opening of the specimen bag, wherein the proximal portion of the pull string extends proximally from the actuation handle; and
a drain tube defining a longitudinal bore, the drain tube having a proximal portion, a distal portion communicating with the interior of the body of the specimen bag, and pores at the distal portion of the drain tube.
11. The specimen retrieval device of claim 10 , wherein the at least one pull string includes two pull strings.
12. The specimen retrieval device of claim 11 , wherein the proximal portion of each of the two pull strings extends proximally from the actuation handle.
