Abstract: A tissue specimen retrieval device includes a first shaft and a second shaft telescopically movable relative to the first shaft. The second shaft supports an end effector assembly at a distal end thereof. The end effector assembly includes a tissue specimen bag supported by a first bag arm and a second bag arm. The first and second bag arms open the tissue specimen bag when the second shaft is in the deployed position. An insertion cap extends outwardly from the tissue specimen bag. The insertion cap retains the first and second bag arms at distal ends thereof. The insertion cap includes a release mechanism. The release mechanism releases the first and second bag arms from the insertion cap upon retraction of the second shaft from the deployed position.

Abstract: A tissue specimen retrieval bag assembly includes a tissue specimen bag having an open proximal end and a closed distal end, the proximal end including a cuff defined therein and extending therearound. A flexible bag brim is disposed within the cuff and is transitionable between a first, collapsed configuration and a second, expanded configuration. The flexible bag brim includes a cross section configured to facilitate both furling the tissue specimen bag onto itself around the bag brim when the bag brim is disposed in the second, expanded configuration and securing the tissue specimen bag in a desired furled configuration.

Abstract: A removable seal assembly configured to engage an access device includes a body including a proximal portion, a distal portion, and a passageway extending longitudinally therethrough. The proximal portion defines an annular distally-oriented surface and the distal portion defines an annular proximally-oriented surface. The body is configured for positioning within an access device such that the annular distally-oriented surface and the annular proximally-oriented surface engage opposing surfaces of the access device therebetween. An O-ring disposed about the body between the annular distally-oriented surface and the annular proximally-oriented surface. The O-ring is configured to establish a fluid tight-seal between the body and the access device.

Abstract: An electrosurgical system includes an electrosurgical generator having active and return terminals, an electrosurgical instrument including an active electrode, a return instrument including a return electrode, an active plug configured to connect to the active terminal of the generator, a return plug configured to connect to the return terminal of the generator, an active cable extending from the return plug to the electro surgical instrument, a return cable extending from the return plug to the return instrument, a connector cable extending from the active plug to the return plug, and a mechanical switch mechanism disposed within the return plug. The mechanical switch mechanism has a disengaged position in which the active plug is electrically disconnected from the active cable and an engaged position in which the active plug is in electrical communication with the active cable.

Abstract: A surgical system includes an active terminal, a return terminal, an active electrode, a return electrode, an active plug configured to connect to the active terminal, and a return plug configured to connect to the return terminal. The return plug is coupled to the return electrode and coupled between the active plug and the active electrode. The return plug is configured to break an electrical connection between the active plug and the active electrode when the return plug is not connected to the return terminal and to establish an electrical connection between the active plug and the active electrode when the return plug is connected to the return terminal.

Abstract: A tissue guard includes a body defining an open proximal end, an open distal end, and a lumen extending through the body between the open proximal end and the open distal end. The tissue guard further includes a lip extending radially outwardly from the open proximal end of the body. The lip includes a plurality of spaced-apart cut-outs defined about the outer circumference of the lip to define a plurality of tabs of the lip. Each tab includes an outer edge segment. The body and the lip are monolithically formed as a single piece of material.

The actuation assembly includes a handle assembly, an elongated member, a release rod, and a holding assembly. The bag locking mechanism is disposed in mechanical cooperation with the handle assembly and enables the actuation assembly to selectively retain the bag assembly. The articulation locking assembly is disposed in mechanical cooperation with the handle assembly and is configured to selectively lock the holding assembly in a first position where at least a portion of the holding assembly is disposed along a longitudinal axis defined by the elongated member.

Abstract: A handle assembly for actuating an end effector includes a feedback mechanism for providing an audible and/or tactical response to indicate to the user that the handle assembly is fully actuated. The feedback mechanism may include a hammer member configured to strike a surface of the handle assembly to create the audible and/or tactical response.

Abstract: A rotation knob assembly, handle assembly including the same, and surgical instrument including the same are disclosed. An outer knob of the assembly defining a longitudinal lumen and at least one transverse aperture having a threaded portion and a smooth portion. An inner sleeve of the assembly includes a body defining a longitudinal lumen and at least one transverse. At least one stepped pin of the assembly includes a body portion disposed within the smooth portion of the at least one outer knob transverse aperture and a tip portion disposed within the at least one inner sleeve transverse aperture to fix the outer knob and the inner sleeve with one another. At least one screw of the assembly is threadingly engaged within the threaded portion of the at least one outer knob transverse aperture to retain the outer knob and the inner sleeve fixed with one another.

Abstract: A gastrectomy device includes an elongated member and a tube. The elongated member has a proximal end and a distal end and defines a longitudinal side window disposed adjacent the distal end. The elongated member defines a first longitudinal channel, a second longitudinal channel, and a plurality of side apertures. The first longitudinal channel is in communication with the longitudinal side window and the plurality of side apertures is in communication with the second longitudinal channel. The tube extends through the first longitudinal channel. An array of lights is associated with the tube to provide illumination. The tube is movable through the elongated member between a first state, in which the tube is disposed within the first longitudinal channel of the elongated member, and a second state, in which a portion of the tube extends through the longitudinal side window of the elongated member.

Abstract: A surgical clip applier is provided and includes a ratchet mechanism having a rack member connected to a drive channel such that axial translation of the drive channel results in axial translation of the rack member, the rack member defining a first set of teeth along a first side thereof and a second set of teeth along a second side thereof.
