Abstract: A surgical access system includes an access device and a distal smoke evacuator. The access device includes a proximal rim configured for positioning on an external side of an opening in tissue, a distal rim configured for positioning on an internal side of an opening in tissue, and a body interconnecting the proximal and distal rims. The body is configured to extend through an opening in tissue and defines a passageway extending therethrough for insertion of a surgical instrument through the opening in tissue into an internal surgical site. The distal smoke evacuator is integrated into or coupled to the distal rim. The distal smoke evacuator includes a tube ring adapted to connect to a source of suction to evacuate smoke circumferentially about an internal side of an opening in tissue.

Abstract: A device for furling a tissue specimen retrieval bag includes a housing supporting a spindle assembly therein, the spindle assembly including a drive shaft having a proximal end, a distal end, and a gear disposed therebetween. An activation switch is pivotably coupled to the housing and is configured for selective, operable engagement with the gear. The activation switch is selectively positionable relative to the gear between a first position wherein the gear and drive shaft are locked from rotation in a first direction and a second position wherein the gear and drive shaft are free to rotate in the first direction. An elongated shaft is operably coupled to the distal end of the drive shaft and is configured for rotation therewith. A biasing element is configured to provide a rotational load to the drive shaft.

Abstract: An electrode assembly for an electrosurgical instrument includes a housing configured to operably receive a distal end of an instrument shaft, the housing including a pair of opposing spring clips. An active electrode is included having a proximal end configured to engage the distal end of the shaft and includes a cutting edge defined about a periphery thereof. An insulator is included that encapsulates the active electrode while leaving the cutting edge exposed. A pair of return electrodes is included that is each configured to operably engage an exposed side of the insulator, each return electrode including a recess defined therein configured to removably receive a distal end of each respective spring clip such that, upon selective engagement of the active electrode with the distal end of the shaft, each spring clip removably snaps into each respective recess to removably lock the active and return electrodes to the housing.

Abstract: A kit for extracting a tissue specimen includes a specimen container having a proximal rim and a specimen bag operably supported about the proximal rim and depending therefrom. The specimen bag includes a plurality of ribs depending from the proximal rim having a series of mechanical interfaces associated therewith and extending therealong. The kit also includes a cutting guard having a body with proximal and distal ends. The distal end is configured for insertion within the specimen bag when disposed within an incision and the proximal end defines an opening therein configured to facilitate introduction of one or more surgical instruments therethrough. The cutting guard includes one or mechanical interfaces operably associated with the body of the cutting guard configured to selectively engage one of the series of mechanical interfaces of one of the plurality of ribs of the specimen container upon insertion of the cutting guard within the incision.

Abstract: A tenaculum includes a first handle and a second handle pivotally coupled to each other about a pivot pin. The first handle includes a palm grip configured to support a palm of a user's hand. The second handle includes a loop defined therein configured to support a user's digit to facilitate pivoting the first handle toward the second handle. A first grasper arm extends from the first handle. A second grasper arm extends from the second handle. The first and second grasper arms are configured to grasp tissue. A first ratchet extension extends from the first handle towards the second handle and a second ratchet extension extends from the second handle towards the first handle. The first ratchet extension is configured to selectively engaged the second ratchet extension upon movement of the first and second handles towards one another to engage tissue between the first and second grasper arms.

Abstract: An instrument port for surgical instruments includes a patient interface body configured to engage a patient access point, e.g., wound. The patient interface body includes a distal end configured to facilitate insertion into the patient access point and a proximal end including a lip defining a cuff therein. The patient interface body including a channel defined therethrough that extend from proximal to distal ends. A flexible seal is configured to securely seat within the cuff and includes an instrument opening configured to align with the channel. A seal guard is configured to sit atop the flexible seal and includes an instrument opening configured to align with the channel and the flexible seal instrument opening. A port cover is configured to engage the lip to encapsulate the flexible seal and the seal guard and defines an opening configured to align with the channel, the flexible seal instrument opening and the seal guard opening.

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 and is movable relative to the first shaft between a retracted position, wherein the end effector assembly is disposed within the first shaft, and a deployed position, wherein the end effector assembly extends from the first shaft in an expanded configuration. The end effector assembly includes a bag brim having a wire support with first and second ends that operably engage the distal end of the second shaft. The bag brim is transitionable from a first collapsed configuration within the first shaft to an expanded configuration upon deployment therefrom. The wire support includes torsion springs disposed between the first and second ends that cooperate to facilitate expansion of the bag brim upon deployment from the first shaft.

Abstract: A specimen containment device includes an actuation assembly, a bag assembly, a bag locking mechanism, and an articulation locking mechanism. 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 specimen retrieval device includes an elongated shaft assembly having a proximal end portion and a distal end portion. An end effector is supported on the distal end portion of the elongated shaft assembly and includes a first arm and a second arm. The first arm includes a first distal finger and the second arm includes a second distal finger. The first and second fingers are configured to selectively engage one another to support a collection bag on the first and second arms.
