- 3. Apparatus according to claim 2 comprising a pair of manifolds disposed in a recessed portion of said cylindrical body's interior passageway, said manifolds comprising an open end located in said proximal end of said cylindrical body and a plurality of openings disposed along at least one side of said recessed portion so as to provide filament conduits for said plurality of closure filaments.
- 4. Apparatus according to claim 3 comprising a plurality of longitudinally-extending rigid spars securely fastened to said net.
- 5. Apparatus according to claim 4 wherein said closure filaments slidably pass through said openings formed in said spars.
- 6. Apparatus according to claim 5 wherein said at least one pulling end extends through one of said manifolds and is operatively fastened to said retracting means.
- 7. Apparatus according to claim 6 wherein said net further comprises a deployment ring attached to at least one of said longitudinally-extending spars.
- 8. Apparatus according to claim 1 wherein said containment element comprises a cylindrical bag having a closed off distal end and an open proximal end.
- 9. Apparatus according to claim 1 wherein said cylindrical body is pivotally connected to a hinge positioned at said shaft's distal end.
- 10. Apparatus according to claim 9 wherein said handle assembly further comprises a sleeve slidably surrounding said shaft and adapted for covering said hinge.
- 11. Apparatus according to claim 10 wherein said handle assembly houses said retracting means.
- 12. Apparatus according to claim 11 wherein said retracting means comprise an advancing mechanism and a holding mechanism.
- 13. Apparatus according to claim 12 wherein said advancing mechanism and said holding mechanism are substantially identical to one another and further wherein said advancing mechanism is fastened to at least two piston rods so as to reciprocate back and forth within said shaft's interior passageway and said holding mechanism is fixably fastened to an interior surface of said shaft.
- 14. A morcellator system comprising a morcellator device in combination with a tissue containment device,
- said morcellator device comprising:
- an outer tube having a distal end terminating in a distal end surface, a proximal end, an internal passageway extending between said distal end and said proximal end, and an opening formed in said distal end at a location proximal to said distal end surface and communicating with said internal passageway;
- an inner tube having a distal end terminating in a distal end surface adapted for morcellating tissue, a proximal end, and an interior passageway extending between said distal end of said inner tube and said proximal end of said inner tube, with said inner tube being sized and disposed so as to make a close sliding fit within said outer tube;
- a handle assembly comprising a body and actuating means, with said proximal end of said outer tube being attached to said body and with said proximal end of said inner tube being attached to said actuating means;
- said actuating means being adapted to move said inner tube between (1) a first distal position wherein said opening formed in said distal end of said outer tube is closed off by said inner tube, and (2) a second proximal position wherein said opening formed in said distal end of said outer tube is at least part way open;
- first tissue holding means connected to said inner tube and projecting into the interior passageway of said inner tube so as to permit tissue to move proximally through said inner tube and to prevent tissue from moving distally through said inner tube; and
- second tissue holding means connected to said outer tube and projecting into said interior passageway of said inner tube so as to permit tissue to move proximally through said outer tube and to prevent tissue from moving distally through said outer tube; and
- said tissue containment device comprising:
- a shaft having a distal end, a proximal end, and an interior passageway extending between said distal end and said proximal end;
- a cylindrical body releasably connected to said distal end of said shaft, said cylindrical body comprising a distal end, a proximal end and an interior passageway extending between said distal end and said proximal end of said cylindrical body, and further comprising at least one manifold located within said cylindrical body's interior passageway, said manifold being adapted to guide closure means;
- containment means deployable from said cylindrical body, said containment means comprising a flexible, generally cylindrical containment element, at least one substantially rigid, longitudinally-extending spar connected to said flexible, generally cylindrical containment element, a plurality of openings formed in said spar, and closure means extending out of said at least one manifold and through said plurality of openings formed in said spar wherein said containment element is sized so as to receive both said tissue and said distal end of said outer tube of said morcellator device;
- a handle assembly;
- release means for permitting said containment means to be moved from (1) a first fully retracted position wherein said containment element is substantially fully withdrawn into said cylindrical body's interior passageway, and (2) a second fully deployed position wherein said containment element is substantially fully extended out of said cylindrical body's interior passageway; and
- retracting means connected to said closure means and adapted to move said containment means from said aforementioned second fully deployed position wherein said containment element is substantially fully extended out of said cylindrical body's interior passageway, to (3) a third intermediate position wherein said containment element is partially withdrawn into said cylindrical body's interior passageway, said retracting means being adapted to progressively retract said containment element further and further into said cylindrical body's interior passageway.
