Abstract: A surgical retrieval apparatus includes a specimen retrieval bag including a rim movable from a collapsed configuration when positioned within a delivery tube to an automatically expanded configuration when advanced from the delivery tube. The rim is configured to receive a tissue specimen when the rim is in the expanded configuration. The retrieval bag defines a proximal portion with respect to the incision and a distal portion with respect to the incision. A specimen retrieval system further includes a delivery tube defining a longitudinal axis and includes the surgical retrieval apparatus contained therein that is configured to be inserted through a first opening in a patient's skin. The delivery tube defines an internal volume extending from a proximal end to a distal end of the delivery tube. The surgical retrieval apparatus is separable from the delivery tube.

Abstract: A method of retrieving a tissue specimen comprising inserting a surgical retrieval apparatus through an opening in a patient's skin, the surgical retrieval apparatus including a support member and a retrieval bag extending from the support member and having an opening to receive the tissue specimen. A net is introduced into the retrieval bag and placed over the tissue specimen. The net and retrieval bag are removed from the patient's body to remove the tissue specimen.

Abstract: A surgical retrieval apparatus includes an elongate tubular member having a drive rod slidably disposed therein. A support member is operably coupled to a distal end of the drive rod. A pouch is attached to the support member and has a closed end and an open end. The pouch is securely coupled to the support member.

Abstract: A specimen retrieval apparatus includes a housing having an elongated tubular member extending distally therefrom. The elongated tubular member defines a longitudinal axis. An end effector assembly is coupled to a distal end of the elongated tubular member. The end effector assembly is configured to retain a specimen retrieval bag thereon. An articulation mechanism is operatively coupled to the elongated tubular member and the end effector assembly. The articulation mechanism is configured for selectively articulating the end effector assembly with respect to the longitudinal axis of the elongated tubular member.

Abstract: A surgical retrieval apparatus includes a housing defining a longitudinal axis and including an elongated sleeve extending distally therefrom. The housing and the elongated sleeve cooperate to define a lumen extending longitudinally therethrough. A shaft having an end effector disposed at a distal end thereof is selectively translatable between a first position, wherein the end effector is disposed within the elongated sleeve, and a second position, wherein the shaft is translated through the lumen such that the end effector extends distally from the elongated sleeve. An articulation mechanism operably coupled to the end effector is configured for articulating the end effector relative to the longitudinal axis. A specimen retrieval bag is coupled to the end effector and is deployed therefrom upon movement of the end effector from the first position to the second position.

Abstract: An instrument for cleaning a scope lens having an elongated sheath having proximal and distal end portions and a sheath interior and exterior. The sheath interior is dimensioned and configured to slidingly receive a scope therein. A fluid conduit transports fluid and has a fluid discharge opening to deliver fluid to the lens of the scope, the conduit coupled to the sheath exterior.

Abstract: A method and system for removing tissue from a body cavity is provided. The system includes a retrieval bag that is insertable through a first incision in tissue and includes open and closed ends. A surgical instrument is insertable into the body cavity and configured to grasp and excise a sample/specimen from within the body cavity and selectively substantially seal the retrieval bag. A fluid circulator in fluid communication with the surgical instrument and the open end of the retrieval bag is configured to evacuate gaseous matter from within the body cavity and into the open end of the retrieval bag such that the retrieval bag substantially encircles the excised tissue specimen.

Abstract: A method for modifying a tissue specimen includes providing a specimen modifying apparatus configured to modify the specimen to thereby prevent seeding from the specimen. The specimen modifying apparatus is inserted through an opening in tissue and positioned adjacent the tissue specimen to be modified. The tissue modifying apparatus is activated to modify the tissue specimen to thereby inhibit seeding from the tissue specimen.
