Abstract
A specimen retrieval device includes a tubular body, an inner shaft slidably positioned within a longitudinal bore of the tubular body, and a specimen bag supported on the distal portion of the inner shaft. In embodiments, the tubular body tubular body is formed of a lubricious material. The specimen bag is formed from a pattern and welded by a radiofrequency welder. The specimen bag includes a tail section through which the inner shaft passes, and the tail section may be attached to a handle at a proximal portion of the inner shaft.
Claims13
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;
- and
- a specimen bag supported on the support member at the distal portion of the inner shaft, the specimen bag including an open end, a body, and a tail portion having a longitudinal bore through which the inner shaft passes,
- wherein the inner shaft is movable in relation to the tubular body from a non-actuated position in which the specimen bag is positioned in a non-deployed state within the longitudinal bore of the tubular body to an actuated position in which the specimen bag is positioned in a deployed state externally of the distal portion of the tubular body.
A method comprising:
- cutting a fabric to form a pattern having a body portion and flaps that may be folded and attached to the body portion of the pattern to form a specimen bag;
- cutting holes along the periphery of the pattern;
- placing the pattern on a radiofrequency welder and locating the pattern in the proper position with the holes along the periphery of the pattern;
- folding at least some of the flaps of the pattern and attaching them to the body portion of the pattern with the radiofrequency welder to form a channel at a mouth of the specimen bag;
- placing a reinforcement tab at a proximal portion of the pattern;
- folding a flap at the proximal portion of the pattern and attaching it to the body portion of the pattern with the radiofrequency welder to form a tail section of the specimen bag, the tail section including the reinforcement tab sandwiched between the flap and the body portion of the pattern;
- and
- folding a last flap at a distal portion of the pattern and attaching it to the body portion of the pattern with the radiofrequency welder to form a body of the specimen bag.
