    摘要: In accordance with the present invention, there is provided a lie loaded packing assembly for a valve which comprises a valve body defining a passage having a valve stem moveably disposed therein and selectively moveable between open and closed positions. Extending about a portion of the valve stem is a packing. One end of a sleeve of the valve bears axially onto and compresses the packing, with a spigot of the valve being cooperatively engaged to the opposite end of the sleeve. A clamp of the valve is cooperatively engaged to the valve body, with a pair of bolts extending between and being secured to the clamp, the spigot, and a flange member which is itself cooperatively engaged to the spigot. The combination of the bolt, spigot and flange member provide an integral spring construction for the valve.

    摘要: An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop positioned therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.

    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: A trocar system for providing access across a body wall includes a trocar and an anchor provided in the form of a first helix. The anchor is adapted for placement in an operative position wherein the anchor extends at least partially through the body wall. A second helix formed on the trocar is size and configured to engage the first helix of the anchor so that rotation of the trocar relative to the anchor moves the second helix along the first helix. In this manner, the trocar is drawn into the anchor as it moves into the body wall. A proximal force applied to the anchor resists tenting of the abdominal wall. The anchor also holds the layers of the body wall together thereby resisting peritoneal separation.

    摘要: A surgical access device is adapted to facilitate access through an incision in a body wall having an inner surface and an outer surface, and into a body cavity of a patient. The device includes first and second retention members adapted to be disposed in proximity to the outer surface and the inner surface of the body wall, respectively. A membrane extending between the two retention members forms a throat which is adapted to extend through the incision and form a first funnel extending from the first retention member into the throat, and a second funnel extending from the second retention member into the throat. The throat of the membrane has characteristics for forming an instrument seal in the presence of an instrument and a zero seal in the absence of an instrument. The first retention member may include a ring with either a fixed or variable diameter. The ring can be formed in first and second sections, each having two ends. Couplings can be disposed between the ends to accommodate variations in the size of the first retention member. The first retention member can also be formed as an inflatable toroid, a self-expanding foam, or a circumferential spring. A plurality of inflatable chambers can also provide the surgical access device with a working channel adapted for disposition across the body wall. A first retention member with a plurality of retention stations functions with a plurality of tethers connected to the membrane to change the shape of the membrane and the working channel. A stabilizing platform can be used to support the access device generally independent of any movement of the body wall.

    摘要: A positionable internal retraction device is provided comprising a malleable ring member and a web-like structure. The retraction device operates to temporarily reposition tissues and organs from an operative site to provide a clear access and visual path for the surgeon. The ring member may be elongated, twisted, folded, bent or deformed to provide an appropriate insertion profile and subsequent functional shape. The retraction device may be shaped for both open and minimally invasive surgeries. The retraction device is atraumatic and may be used for retraction of delicate tissues and organs. The ring member may have different bending biases. The web-like structure may be constructed of any elastic material that can stretch and recover from the shaping and reshaping of the ring member. In another aspect of the invention, the ring member further comprises an internal lumen defining a wall, which may be of any geometric shape providing a desired bending bias. The ring member may further include a reinforcement member placed within the lumen and made of a “shape memory” material that allows the reinforcement member to return to its desired shape or condition after being bent. The reinforcement member may be placed in some sections of the ring member to keep these sections substantially straight. Each of the ring member, the reinforcement member and the internal wall may have a cross-section or profile of any geometric shape to provide a desired bending bias in a preferred plane. In yet another aspect of the invention, the ring member further comprises a second lumen and a second reinforcement member placed within the second lumen to provide a desired bending bias.
