Abstract
Embodiments disclose surgical instruments for retrieving excised tissue from a patient and, more particularly, to endoscopic surgical instruments such as pouches or retrieval bags for the removal of tissue through a small incision.
Claims20
A surgical device for removal of biological specimens from within a patient, the device comprising:
- a retrieval bag having an open end, a closed end, and at least one wall extending between the open end and the closed end;
- one or more memory wires configured for coupling to the retrieval bag wherein the memory wire is configured to collapse into a first compressed shape when receiving a compressive force, and expand into a second resting shape when the compressive force is released;
- wherein responsive to the one or more memory wires expanding, the retrieval bag expands;
- and wherein responsive to the one or more memory wires collapsing, the retrieval bag collapses.
1 more element
The surgical device of claim 9 further including:
- an introducer comprised of a longitudinally extending first lumen with a first proximal end and a first distal end with a first diameter;
- and
- a movable actuator comprised of a longitudinal body having a second diameter smaller than the first diameter, a second proximal end and a second distal end;
- wherein the actuator is positioned within the introducer and movable longitudinally through the lumen of the introducer;
- wherein the retrieval bag is positioned in a first compressed position within the lumen of the introducer and distal to the distal end of the actuator;
- wherein upon application of a first push or compressive force upon the actuator from the actuator's second proximal end and towards the actuator's second distal end, the retrieval bag is moved from the first compressed position within the lumen of the introducer to a second deployed position outside of the introducer.
