    摘要： The tissue retrieval system deploys a tissue bag at the surgical site. The bag is supported by the system as tissue is placed within the bag and is closed to isolate the collected tissue and allow the bag and collected tissue to be removed from the body. The bag can be reopened and re-closed as desired through use of a guide bead and cord. The bead also facilitates removal of the collected tissue.

    摘要： A surgical access system comprises a trocar, an insufflating optical obturator slidably insertable into the trocar, and a laparoscope slidably insertable into the obturator. A distal end of the obturator comprises a tip, at least a portion of which comprises a wall with a generally uniform thickness comprising a transparent material. At least one vent hole disposed at the obturator tip is fluidly connected to a gas flow channel defined by an interior surface of the obturator and the laparoscope, which is fluidly connected to an insufflation gas inlet disposed at a proximal end of the trocar. Improved optical characteristics of the trocar system permit precise and accurate visual placement thereof into a body cavity. Accordingly the access system is suitable as a first entry surgical access system. Embodiments of the trocar access are also useful for drug delivery, and/or for fluid and/or tissue aspiration.

    摘要： A surgical access device includes a seal housing and a roller disposed in the housing and defining a working channel. The roller may be stationary or movable within the seal housing to form both a zero seal in the absence of an instrument, and an instrument seal in the presence of an instrument. Rotation of the roller is contemplated and low-friction surfaces are discussed to reduce instrument insertion forces. Multiple rollers, wiper elements, low-friction braid, pivoting elements and idler rollers are contemplated. The rollers will typically be formed of a gel material in order to facilitate the desired compliance, stretchability and elongation desired.

    摘要： The invention is directed to a trocar seal adapted to form a seal around a surgical instrument, the trocar seal comprising a housing having an axis extending between a proximal end and a distal end and forming a working channel sized and configured to receive the surgical instrument; an elastomeric septum seal having a proximal face and a distal face, the septum seal being disposed in the housing and extending transverse to the axis of the housing across the working channel; portions of the septum seal defining a hole having a diameter less than or equal to the diameter of the surgical instrument so that during insertion of the instrument along the working channel the septum seal forms a seal with the instrument; and at least one structure formed integrally with or proximate to the septum seal to prevent inversion of the septum seal upon withdrawal of the surgical instrument. The septum seal or the housing may further comprise a sidewall to include the structure extending from the sidewall to the distal face of the seal to tether the seal distally. The structure may be integrally formed with the proximal face of the septum seal to reinforce the seal, or the structure may be integrally formed with the distal face of the septum seal to tether the seal distally. The structure may be an annular reinforcement or rib, and is formed so as to allow side-to-side movement or floatation of the seal. The trocar seal may further comprise a plurality of radially extending ribs formed on the proximal or distal face of the septum seal to reinforce the seal. The trocar seal may further comprise a tensile element formed on the distal face of the septum seal.

    摘要： A surgical access device or trocar defines an access channel for instruments extending from a proximal end to the distal end thereof. The trocar comprises a cannula and a seal assembly disposed at the proximal end of the cannula. The seal assembly comprises a first or zero seal, a second or instrument seal, and a trocar shield disposed proximally of the first seal and the second seal. The first seal seals the access channel in the absence of an instrument extending therethrough. The second seal seals the access channel in the presence of an instrument extending therethrough. The trocar shield protects the first seal and second seal from damage as an instrument is advanced through the access channel. The trocar shield comprises an open proximal end and a tapered distal end comprising a plurality of longitudinal pleats, converging in an opening.
