This invention is a device (10) for use in endoscopic operative procedures inclu ding an elongate outer member (12), an elongate inner member (14) received in the outer member (12), and a loop forming portion (16) c onnected between the outer member (12), and the inner member (14). The loop forming portion (16) is movable from externally of the bod y from a non-deployed position to a deployed position to form a loop structure. The loop forming portion is movable from externally of the body in a squeezing action to squeeze collected substances from the loop forming portion (16) and into a collection bag (72) of a collection system prior to withdrawal of the loop forming portion (16) from the body. The collection bag (72) is movable between a non-exp anded position facilitating introduction in the body, and an expanded position within the body allowing the loop forming portion (16) to b e positioned in the interior of the collection bag (72), and thereafter moved in the squeezing action. |
