摘要： A surgical cutting instrument is disclosed for percutaneously debulking tissue through an access sheath commonly used in minimally invasive laparoscopic or endoscopic surgical procedures. The cutting instrument includes a inner rotary member tube having a cutting edge at the distal end thereof for cutting and slicing tissue. The outside surface of the rotary inner cutting member tube and outer sheath annularly close about the distal ends thereof for preventing perforation of the surgical tissue bag in which the tissue is contained. The inner cutting member tube includes a hollow passageway for suctioning and aspirating tissue and fluid through the tube and into a collection chamber or out through a vacuum or suction line attached thereto. Vacuum or suction control ports are included at the proximal end of the inner cutting member tube and stationary sheath for also controlling the amount of vacuum or suction applied to the tissue. The surgical cutting instrument includes a control handle for grasping by the physician. A collection chamber is connected to a coupler connected to the stationary sheath for collecting tissue therein. The inner cutting member tube extends through the collection chamber to a drive motor or to a remotely positioned rotary drive mechanism. A vacuum line is attached to the collection chamber for drawing tissue and fluid through the inner cutting member tube and into the collection chamber.

摘要： A surgical access device is adapted for performing laparoscopic surgical procedures with at least one instrument passing through the surgical access device and through an incision in the abdominal wall of a patient with the abdominal cavity pressurized with an insufflation gas. The surgical access device is adapted to provide instrument access to the abdominal cavity for surgical procedures while generally maintaining insufflation pressure in the abdominal cavity. The surgical access device comprises an access seal. The access seal comprises a material formed of a mixture comprising a triblock copolymer and an oil. The access seal is adapted to be disposed relative to the abdominal wall in an operative position. The material of the access seal is adapted to form a seal to generally maintain insufflation pressure within the abdominal cavity. At least one opening is formed through the material of the access seal between a proximal portion and a distal portion of the access seal. The at least one opening when operatively disposed is in communication with the incision and forms a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The material of the access seal is adapted to conform to a surface of an instrument inserted through the working channel.

摘要： A surgical obturator adapted to penetrate a body wall includes an elongate shaft having an axis which extends between a proximal end and a distal end. A bladeless tip, disposed at the distal end of the shaft has an outer surface which extends to a blunt point. The outer surface has a pair of side sections separated by an intermediate section. The side sections extend from the blunt point radially outwardly with progressive positions proximally along the axis. These side sections include a distal portion in proximity to the blunt point, and a proximal portion in proximity to the shaft. The distal portion of the side section is twisted radially with respect to the proximal portion of the side section. The outer surface in radial cross section has the general configuration of a geometric shape which rotates in a first direction about the axis with progressive proximal radial cross sections along the axis.

摘要： A surgical access device includes an access seal adapted to be disposed within an incision within an abdominal wall. The access seal has an external flange adapted to be disposed external to the abdominal wall and an internal flange adapted to be disposed internal to the abdominal wall. The access seal with flanges is formed monolithically. There are access channels through the access seal. The access channels span the thickness of the abdominal wall and form working channels between a location external to the abdominal wall and a location internal to the abdominal wall. The access seal is formed of an elastomeric material adapted to conform to a surface of an instrument inserted through the working channel to form an instrument seal along a length spanning the thickness of the abdominal wall. The elastomeric material is adapted to form an abdominal seal within the abdominal wall.

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.
