    摘要: A trocar fixation device includes a cannula and an elongate tube mounted onto and coupled to the exterior surface of the cannula with the distal end of the cannula extending distally beyond the distal end of the elongate tube. The elongate tube includes a plurality of slits cut at an angle to a longitudinal axis of the elongate tube. The trocar fixation device is activated by rotating the proximal-end region of the elongate tube in a first direction and is deactivated by rotating the proximal-end region of the elongate tube in a second direction, opposite to the first direction. Activation of the trocar fixation device compresses the material positioned between adjacent slits and forces the material radially outwardly, away from the exterior surface of the cannula, thereby forming ridges. Deactivation of the trocar fixation device returns the exterior surface of the elongate tube to a substantially smooth condition.

    摘要: A duckbill check valve and septum combination includes a hollow elastomeric body having an open proximal end, a closed distal end and a pair of opposed flat portions that form a distal edge. The distal edge includes a slit having a periphery that is smaller than the periphery of the instrument inserted therethrough. The slit provides a zero seal in the absence of an instrument and an instrument seal in the presence of an instrument. A shield including a tubular member and a plurality of blades protruding distally from the distal end of the tubular member may be placed inside the check valve and operates to center and guide the surgical instrument through the blades before expanding the slit of the check valve. An instrument inserted into the check valve stretches the distal portion of the duckbill valve to form a septum-like seal around the inserted instrument.

    摘要: The present invention relates to a surgical access device comprising an elongate tubular member having a working channel and an axis extending between a proximal end and a distal end, a septum seal integrally formed at the distal end of the tubular member, and a zero seal disposed at the distal end of the tubular member and distal to the septum seal, the zero seal being sized and configured to seal when no instrument is in place within the working channel of the tubular member, and the zero seal being coupled to the septum seal and having properties to float with the septum seal relative to the tubular member. The tubular member may be formed from an elastomeric material. The tubular member has a wall that may be rigid or semi-rigid, and the tubular member may be reinforced with a coil along a portion of the tubular member. The tubular member may include a distal, mechanically deployable shielding portion. The zero seal may be a duckbill seal constructed with one or more intersecting sealing portions. The duckbill seal may comprise of opposing lip portions separated by a slit portion. The opposing lip portions are coated with or attached to a soft or occlusive material. The occlusive material is one of Kraton, polyurethane or the like. The occlusive lip portions allow a surgical item such as a suture to extend through the slit portion without disrupting the seal. In one aspect, the tubular member and the septum seal are molded together as a single unit and the zero seal is then bonded or fused to the septum seal. In another aspect, the tubular member, the septum seal and the zero seal are all molded together or integrally formed as a single unit. The tubular member may further comprise flexibility enhancing features to allow the tubular member to flex in response to a motion of a surgical instrument within the working channel of the tubular member.

    摘要: The present invention relates to a surgical access port for insertion into a body cavity having an elongate tubular body extending along an axis between a proximal end and a distal end, and a tip disposed at the distal end of the tubular body for penetrating through a body wall and into the body cavity. The distal tip operates to move from a first, penetrating position to a second, retaining position when the body wall has been traversed. The surgical access port may further comprise a seal housing operably connected to the proximal end of the tubular body, the seal housing having an access port providing an opening into the tubular body to allow passage of surgical instruments. The distal tip may be sharp, pointed or bladed. The distal tip may also be substantially blunt or have a conical surface. The access port may further comprise a retention member for connecting the tubular body and the distal tip. The retention member may be biased to hold the distal tip in an off-axis position when there is no axial load, or it may be lightly held in axial alignment and subsequently deflected in the presence of an instrument within the tubular body. The distal tip, which may comprise one or more parts or petals, may reposition to the side of the tubular body in a substantially right-angled condition in the second, retaining position. The repositioned tip remains in an off-axis condition until removal of the access port, at which time the distal tip automatically realigns with the axis of the tubular body as the access port is withdrawn from the body wall. The tubular body may be a thin walled tube. The distal tip may comprise a conical, tapered or rounded shape to separate tissue layers. The distal tip may be solid or hollow, which may act as a specimen bag by closing on a specimen and pulled inside the tip during removal of the access port. The distal tip may be formed from a clear material to allow viewing through an endoscope during placement of the surgical access port.

    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 laparoscopic insufflation device is provided in the configuration of a coil with a blunt tip. The device is capable of passing through the abdominal wall without cutting tissue, and exiting the abdominal wall substantially parallel to the inner surface. While rotation of the coiled device results in forward movement through the abdominal wall, a counter force can be applied to the device to create a safety space between the wall and the interior organs. With the blunt distal tip, parallel exit angle, and safety space, there is substantially no threat to the interior organs during placement of the device. Further space can be generated with the use of pressured gas to produce an abdominal cavity for the subsequent placement of trocars. By rotatably attaching the coiled insufflation device to a trocar, the advantage of a counter force can be used not only to establish the safety space but also to pull the trocar into the abdominal wall with a counterforce which resists tenting.

    摘要: A drainage catheter is adapted to drain fluid from the body cavity through a body conduit and includes an elongate tube and a retention member disposed at the distal end of the elongate tube. The retention member is adapted for movement between a low-profile state facilitating insertion of the catheter and a high-profile state facilitating retention of the catheter in its operative position. A woven mesh forms at least a portion of one of the tube and the retention member. The woven mesh can be formed of filaments heat-settable so that the catheter automatically moves to the high-profile state. Insertion of the catheter can be facilitated using a stylet which can be removed after insertion to permit the catheter to automatically return to its high-profile state.
