  • Patent number: 10052089
    Abstract: An insertion tongue of the retractor device may be pushed into the subject through the trocar incision, along one side of the organ. The tip of the insertion tongue pushes the impacted organ and its endoscopic recovery bag slightly away from the cavity wall. A scalpel is passed through the insertion guide with the tip of the scalpel blade in the retention guide on the back of the insertion tongue, and with the sharp side of the scalpel blade facing away from the organ and from the tongue of the retractor device. The scalpel is then passed down through the cavity wall, with its tip in the retention guide, while tension on the retractor device handle away from the organ, and gentle outward traction on the organ (and bag) permits removal of the organ (and bag) as soon as the opening is just large enough to allow it.

  • Patent number: 8876709
    Abstract: A surgical retractor for illuminating a surgical field includes an ergonomic handle, a retractor blade coupled with the handle, a quick release mechanism, and an illuminator blade. The retractor blade is adapted to engage and retract tissue, and the quick release mechanism is adapted to couple the handle with the retractor blade. The illuminator blade acts as a waveguide to transmit light by total internal reflection. Light is extracted from the illuminator to illuminate the surgical field. The retractor blade is releasable from the handle without requiring uncoupling of the illuminator blade from the handle and also without requiring optical uncoupling of the illuminator blade from a light source. The retractor may also be adapted to evacuate smoke from the surgical field.

  • Publication number: 20140323808
    Abstract: A surgical assembly includes a cannula and an obturator. The cannula has open proximal and distal ends defining a lumen therebetween. The lumen defines an inner surface of the cannula having a mating structure. The obturator is generally tubular and has an outer surface including a corresponding mating structure. The respective mating structures of the obturator and the cannula engage each other so as prevent relative rotation of the obturator and cannula, and to prevent inadvertent disconnection of an upper valve housing attached to the cannula.

  • Publication number: 20140323809
    Abstract: An instrument access device includes a wound protector and retractor, a proximal assembly coupled to the wound protector and retractor, and an instrument receiver which can be releasably coupled to the proximal assembly. The instrument receiver has a valve assembly through which an instrument is passed and a cannula portion which extends in use through an incision which has been retracted and protected by the retractor. The instrument receiver has an insufflation/desufflation port. The proximal assembly comprises an inner proximal ring member and an outer proximal ring member. The proximal end of the retractor sleeve is located between the proximal ring members. The inner proximal ring member has a slot for receiving and releasably engaging with an insufflation port section of the instrument receiver.

  • Patent number: 8864659
    Abstract: A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, includes a seal anchor member comprising a compressible material and being adapted to transition between a first expanded condition to facilitate securing of the seal anchor member within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract and a second compressed condition to facilitate at least partial insertion of the seal anchor member within the tissue tract. The seal anchor member defines a central longitudinal axis and has leading and trailing ends. At least one longitudinal object port extends between the leading and trailing ends and is adapted for reception of a surgical object whereby compressible material defining the at least one longitudinal object port is adapted to deform to establish a substantial sealed relation with the object.

  • Publication number: 20140303446
    Abstract: A single-arm stabilizer having suction capability includes a single, small leg through which suction can be applied. The leg has an upper surface and a lower surface that are spaced apart to define a chamber. The lower surface includes a plurality of openings that are disposed adjacent each other. A support arm is connected to the leg in order to position the leg as desired. A suction line is in fluid communication with the chamber in order to create a vacuum within the chamber. The stabilizer can be used to stabilize any desired portion of a patient's body, but is particularly effective at stabilizing the septum of a patient's heart. Such stabilization can be accomplished by inserting the leg into the patient's heart through the aorta.

    Abstract: Embodiments of a surgical access system useful for single or limited port procedures comprise a trocar comprising a fixation cannula, a retractor, and a gel cap removably coupled to the retractor. The gel cap comprises a gel pad that acts as an artificial body wall, through which instruments may be inserted into a body cavity, either directly or through one or more trocars. The fixation cannula comprises a retainer and a bolster, which together, capture the artificial body wall therebetween, thereby fixing the trocar thereto. The gel pad permits flexible instrument placement, as well as translational and angular degrees of freedom for the instruments while maintaining a gas tight seal.

  • Publication number: 20140257039
    Abstract: Disclosed herein are systems, devices, and methods for retracting tissue and removing surgical smoke using a smoke evacuation conduit positioned on or within an internal surface of the retractor blade such that the conduit does not protrude onto the external surface of the blade, along with a smoke intake port on or flush with the exterior surface of the blade and set back from the tip to minimize tissue aspiration. The systems and devices allow for the channeling of surgical smoke away from the surgical site while avoiding occlusion of the surgeon's field of view and preserving the surgeon's freedom of motion.
