    摘要: The trocar system includes a cannula insertable through a body wall using an obturator having a distal tip. A traction tread disposed interiorly of the obturator inverts at the distal tip and extends proximally along the outer surface of the obturator or cannula. At the distal tip the tread can facilitate parting rather than cutting the tissue Along the outer surface, the tread can engage the tissue to pull it proximally along the advancing obturator. This produces counter forces which can result in a net proximal force facilitating distention of the abdominal wall and separation of the abdominal wall from internal organs The traction tread can be axially and/or radially continuous. An associated method of operation includes the steps of contacting the body wall with the traction tread at the distal tip, and engaging the body wall with the traction tread along wall portions facing the outer surface

    摘要: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force. An associated method includes the step of rolling the second ring circumferentially of the third ring to form the circumferential retainer.

The hand access system comprises a sheath retractor adapted to dilate a wound stretchable to a desired diameter, the sheath retractor includes a first ring being adapted for disposition interiorly of the wound, a second ring being adapted for disposition exteriorly of the wound, and a sheath being disposed in a generally cylindrical form between the first ring and the second ring and operable to exert a radial retraction force on the wound. The hand access system further comprises a detachable hand seal adapted to be removable from the second ring of the sheath retractor. The sheath retractor may be formed of an elastomeric material, and the hand seal may be formed of a gel material and includes a slit providing an instrument seal in the presence of an instrument or hand and a zero seal in the absence of the instrument or hand. In another aspect, there is disclosed a surgical access device adapted for disposition relative to an incision in a patient comprising a valve including a plurality of overlapping sheets defining an access channel, and a ring having an inner diameter for holding the valve by fixing each of the overlapping sheets along a portion of the perimeter, the access channel extends into communication with the incision in the patient. Each of the overlapping sheets includes a portion of the perimeter that is not fixed to the inner diameter of the ring, which provide open edges defining the access channel. The open edges slightly overlap at the center of the ring. The open edges may have different shapes including at least one of a straight edge, concave, convex and a cross-configuration. The hand access device may further comprise a septum seal formed at the proximal and distal ends of the ring.

    摘要: The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may be formed of a thermoplastic or a thermoset material. The ring-shaped elements may include plastic rings, metallic rings, un-reinforced plastic rings and/or metal reinforced plastic rings assembled along the length of the tubular structure to provide variable flexibility and kink-resistance. The tubular structure may have a cross-section of any geometric shape and it may be bent, twisted or curved without kinking. The ring-shaped elements may have different flexural modulus. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. The ring-shaped elements may be metallic and may be bonded with a resilient, flexible elastomeric adhesive, wherein the ring-shaped elements may have different lengths and may be fused closer or further apart to one another depending on the characteristics of a portion or section of the tubing. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. The ring-shaped elements may be truncated to provide a bending bias. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure. In yet another aspect of the invention, some of the ring-shaped elements may be radiopaque, or the ring-shaped elements may comprise of different colors to operate as indicators along the tubular structure.

    摘要: A medical device for viewing inside a body and for retrieving an object from a location within the body, the medical device comprising an endoscope having a tube defining a working channel and a basket engageable with the object. In one embodiment of the invention, the basket does not require a sheath and is disposed through the working channel such that the endoscope operates to contain or activate the sheathless basket. In another embodiment of the invention, a single push wire with a collar at its end is used in place of a sheath to control the opening and closing of the basket. In another embodiment of the invention, a tapered and funnel-shaped sheath surrounding the basket is used to contain or activate the basket. The invention minimizes the basket crossing profile so as to improve fluid flow in the working channel.

    摘要: A surgical access device includes a single valve that forms a seal with the body wall and provides an access channel into a body cavity. The valve has properties for creating a zero seal in the absence of an instrument as well as an instrument seal with instruments having a full range of instrument diameter. The valve can include a gel and preferably an ultragel comprised of an elastomer and an oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The single valve can be used as a hand port where the instrument comprises the arm of a surgeon, thereby providing hand access into the cavity. A method for making the surgical access device includes the combining of a gelling agent with an oil, preferably in a molding process. A method for using the device includes steps for creating an opening with the instrument. In a particular process, an organ can be removed from the body cavity through the single valve to create an organ seal while the organ is addressed externally of the body cavity. The valve and method are particularly adapted for laparoscopic surgery wherein the abdominal cavity is insufflated with a gas thereby requiring the zero seal, the instrument seal, and the organ seal in various procedures.
