    摘要： A surgical access device comprising an instrument access channel extending through an instrument seal and a shroud comprising an inverting region disposed distally of the instrument seal exhibits improved tear-resistance of the instrument seal from instrument manipulation, for example, instrument withdrawals. Some embodiments of the inverting region invert through the instrument seal on instrument withdrawal. Some embodiments of the inverting region induce at least a portion of the instrument seal itself to invert on instrument withdrawal.

    摘要： The invention is directed to a bladeless trocar obturator to separate or divaricate body tissue during insertion through a body wall. In one aspect, the obturator of the invention comprises a shaft extending along an axis between a proximal end and a distal end; and a bladeless tip disposed at the distal end of the shaft and having a generally tapered configuration with an outer surface, the outer surface extending distally to a blunt point with a pair of side sections having a common shape and being separated by at least one intermediate section, wherein each of the side sections extends from the blunt point radially outwardly with progressive positions proximally along the axis, and the shaft is sized and configured to receive an optical instrument having a distal end to receive an image of the body tissue. With this aspect, the tapered configuration facilitates separation of different layers of the body tissue and provides proper alignment of the tip between the layers. The side sections include a distal portion and a proximal portion, the distal portion of the side sections being twisted radially with respect to the proximal portion of the side sections. The intermediate section includes a distal portion and a proximal portion, the distal portion of the intermediate section being twisted in a first radial direction and the proximal portion of the intermediate section being twisted in a second radial direction opposite the first radial direction.

    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.
