Abstract

A device for the collection and removal of body tissue and/or parts in laparoscopic surgery having an elongated tubular member with proximal and distal extremities and a bore extending therethrough. A sack formed of a flexible material with an opening therein is secured by a rod inside the tubular member to the distal extremity of the elongated tubular member. A drawstring is secured to the sack and circumscribes the opening of the sack and controls the opening and closing of the sack. The drawstring extends into the bore and is connected to a slide mounted around the tubular member. A handle is secured to the proximal extremity of the tubular member and finger rings are secured to the proximal extremity of the slide. Movement of the slide towards the distal extremity of the tubular member opens the sack once inside the patient for receiving the tissue or body part, while movement of the slide in a distal direction causes the sack to close to capture the tissue or body part.

Claims

1. In a device for the collection and removal of body tissue and/or parts in laparoscopic surgery on a patient, an elongate tubular member having proximal and distal extremities and having a bore extending therethrough, a sack formed of a flexible material and having an opening therein, means carried by said tubular member securing at least a side portion of said sack within at least a portion of the length of the distal extremity of said elongate tubular member, drawstring means secured to said sack and circumscribing said opening in said sack for opening and closing said opening in said sack, said drawstring means extending into said bore, slide means slidably mounted on said elongate tubular member and secured to said drawstring means in said bore and handle means secured to the proximal extremity of said tubular member and to said slide means for introducing said sack into the patient and for causing relative movement between the tubular member and the slide means to open said opening in said sack for the collection of body tissue and/or body parts in the patient and to close said opening in said sack after collection of the body tissue and/or parts.

2. A device as in claim 1 together with a capsule having an open end mounted on the distal extremity of the elongate tubular member for enclosing the sack for introduction of the sack into the body cavity of the patient.

3. A device as in claim 2 wherein said sack is movable longitudinally of the capsule to permit the sack to be pushed out from the capsule through the open end and to thereafter permit opening of the sack.

4. A device as in claim 2 together with means carried by the capsule for establishing a sealing engagement between the tubular member and the capsule.

5. A device as in claim 1 wherein said drawstring means for opening and closing of said sack is in the form of a relatively rigid filament which upon movement to open said sack causes the opening of the sack to bow outwardly to facilitate the collection of body tissue and/or parts.

6. A device as in claim 1 wherein the sack has a distal extremity, the distal extremity of said sack extending beyond the distal extremity of the elongate tubular member.

7. A device as in claim 1 wherein said handle means is adapted to be held by the hand of the physician and includes first and second members secured to said slide means adapted to be engaged by fingers of the same hand for causing opening and closing of the opening in said sack.

8. A device as in claim 1 wherein said slide means includes a tubular member co-axially and slidably mounted on the elongate tubular member.
