摘要： A tissue retrieval system can contain and withdraw excised tissue specimens from within a body cavity. The tissue retrieval system can include a tissue retrieval bag, a foldable actuator, and an introducer. The foldable actuator can be foldable between an insertion configuration for placement through an access device without the aid of a grasper or applicator, and a deployed configuration for supporting the tissue retrieval bag in an open state. The actuator can have a foldable handle to facilitate withdrawal from the body cavity. After insertion of the tissue specimens into the retrieval bag, the retrieval bag is then cinched closed to prevent spillage of its contents and to prevent contamination of the body cavity and body cavity wall during withdrawal of the retrieval bag from within the body cavity.

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, such as a trocar, includes a pendent valve having an elongate structure extending from a proximal end to a septum valve disposed at a distal end. In operation, the elongate structure follows the angle of the instrument to pre-position the septum valve into the path of the instrument where it is not significantly challenged during instrument insertion or manipulation. The pendant valve can be made to float at both the proximal end and the distal end of the elongate structure, to further reduce the vulnerability of the septum valve. Since the valve is less vulnerable to instrument insertion, it can be formed to minimize friction and maximize the functional range of the access device.
摘要翻译：手术进入装置，例如套管针，包括具有从近端延伸到设置在远端的隔膜阀的细长结构的侧悬阀。在操作中，细长结构遵循仪器的角度，以将隔膜阀预先定位到仪器的路径中，在仪器插入或操纵期间，隔膜阀不会受到严重的挑战。悬挂阀可以制成在细长结构的近端和远端两侧浮动，以进一步降低隔膜阀的脆弱性。由于阀门不易受仪器插入的影响，因此可以形成最小化摩擦力并最大化进入设备的功能范围。

摘要： The invention is directed to a trocar assembly having a channel defined along an elongate axis, the trocar assembly being adapted to receive a surgical instrument, the trocar assembly comprising a septum seal disposed in the channel including a seal tip having a proximal facing surface, the seal tip including portions defining an orifice; and a septum shield including a tubular member having a proximal end and a distal end, and a plurality of blades or leaflets protruding distally from the distal end of the tubular member, the septum shield being placed inside the septum seal such that the blades engage the proximal facing surface of the seal tip. The trocar assembly may further comprise a zero closure seal such as a double duckbill valve disposed in the channel outside of the septum seal. The septum shield operates to reduce the drag force and to minimize axial movement of the septum shield and the instrument during insertion and removal of the instrument through the septum seal. The septum shield may be formed from a rigid plastic material, and the septum seal may be formed of an elastomeric material. The blades or leaflets may overlap or offset one another. The orifice may be expandable to accommodate the instrument having a diameter of about 5-15 mm. The blades or leaflets have distal tips that glide or roll against the instrument during placement of the instrument. The distal tips may comprise of a combination of material, durometer and shield geometry to control the behavior of the septum shield. The trocar assembly may further comprise a second septum shield disposed outside of the septum seal.
