Laparoscopic tissue retrieval system

摘要

A tissue retrieval system can contain and withdraw excised tissue specimens from within a body cavity. The tissue retrieval system can include a tissue retrieval bag, a foldable actuator, and an introducer. The foldable actuator can be foldable between an insertion configuration for placement through an access device without the aid of a grasper or applicator, and a deployed configuration for supporting the tissue retrieval bag in an open state. The actuator can have a foldable handle to facilitate withdrawal from the body cavity. After insertion of the tissue specimens into the retrieval bag, the retrieval bag is then cinched closed to prevent spillage of its contents and to prevent contamination of the body cavity and body cavity wall during withdrawal of the retrieval bag from within the body cavity.

主权项

1. A tissue retrieval system comprising:
a tissue retrieval pouch having an open end, a closed end opposite the open end, and a cuff extending peripherally around the open end; an actuator having a first end, a second end opposite the first end and comprising:
a generally cylindrical segment between the first end and the second end, the cylindrical segment defining a longitudinal axis of the actuator;a hoop segment extending from the generally cylindrical segment to the second end of the actuator, at least a portion of the hoop segment being positioned within the cuff of the tissue retrieval pouch; anda flexible section between the first end and the second end such that the actuator is foldable at the flexible section about an axis transverse to the longitudinal axis between a first configuration in which the hoop segment extends distally from the generally cylindrical segment and a second configuration in which the hoop segment extends proximally from the generally cylindrical segment; an introducer comprising a tubular introducer member having a first end, a second end opposite the first end, and a lumen extending therebetween, wherein the actuator is slidably disposed in the lumen of the introducer such that at least a portion of the hoop segment extends from the second end of the introducer; and a coupler coupling the tissue retrieval pouch to the second end of the introducer and maintaining a position of the tissue retrieval pouch relative to the second end of the introducer.
