摘要： A surgical access device comprising a tissue separating obturator suitable for connection with a cannula is disclosed. The obturator includes an elongate shaft having a transparent distal tip. The elongate shaft extends along a longitudinal axis and defines a lumen. The transparent distal tip has a tapered configuration and includes an inner surface and an outer surface adapted for penetrating tissue. The lumen is sized and configured to receive an optical instrument such as a laparoscope. The surgical access device further includes a scope lock at the proximal end of the shaft portion. The lock includes a multi-fingered collet coaxial with the lumen. The inner diameter of the collet is smaller than an outer diameter of the optical instrument and the fingers of the collet provide frictional engagement with the outer diameter of the optical instrument that is inserted into the lumen of the obturator.

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.

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 tissue retrieval system can include a tissue retrieval bag with an elongate profile. The tissue retrieval bag can have a relatively large volume, but be rollable to a stowed configuration to fit in a relatively small diameter introducer. The tissue retrieval system can include one or more support arms coupled to the tissue retrieval bag, the support arms biased to position the tissue retrieval bag in an access position once deployed from the introducer. A tissue retrieval system can have a hybrid tissue retrieval bag including material properties that vary along the depth of the bag from an open end to a closed end. A tissue retrieval bag can be used in conjunction with an introducer, or as a stand alone tissue retrieval bag.

摘要： The invention is directed to a method for manufacturing a thin-wall, single-piece optical obturator having an integral tip and shaft. The invention includes providing an injection mold defining a mold cavity having a core pin positioned within the mold cavity. The mold includes at least one gate and multiple core support pins between the core pin and the mold cavity walls, with at least one primary core support pin positioned on a side opposite the at least one gate. The method also includes injecting a transparent molten polymeric material having high flow properties into the injection mold such that the polymeric material flows between the surface of the mold cavity and the core pin. The core support pins substantially prevent the core pin from shifting while the polymeric material is injected into the mold. The high-flow nature of the polymeric material allows for complete filling of the mold cavity.

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 moveable 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.
