Definitions

  • the present invention relates to the field of cannulas providing conduits for receiving medical instruments that are to be used in performing surgery in a body cavity.
  • Systems and techniques in which access to the abdominal cavity is gained through a natural orifice are advantageous in that incisions through the skin and underlying muscle and peritoneal tissue may be avoided.
  • Use of such systems can provide access to the peritoneal cavity using an access device inserted into the esophagus, stomach or intestine (via, for example, the mouth, vagina, or rectum). Instruments are then advanced through the access device into the peritoneal cavity via an incision in the wall of the esophagus, stomach or intestine.
  • Fig. 1 is a perspective view of a multi-lumen cannula
  • Figs. 2 A and 2B are perspective views of one of the cannula tubes of Fig. 1 in the collapsed position and the expanded position, respectively.
  • Fig. 3 is a cross-section view taken along the plane designated 3-3 in Fig. 1 in an embodiment having an optional seal within the cannula.
  • Fig. 4 is a cross-section view of a modified form of the port which includes sealing mechanisms.
  • Fig. 1 illustrates a multi-lumen cannula 10.
  • the cannula includes a cannula body 12 having a proximal opening 14 and a distal opening 16.
  • the cannula body may be an elongate overtube positionable to extend from a natural body orifice into a body cavity within which a procedure is to be performed.
  • the cannula body 12 may be an access cannula that extends through an opening in the abdominal wall for single port surgery or laparoscopic procedures.
  • a plurality of collapsible tubes 18 extends through the cannula body 12.
  • Each of the collapsible tubes 18 includes a proximal instrument port 20 positioned outside the proximal end of the cannula body 12 and a distal opening 22 positioned distal to the distal opening 16 of the cannula body 12.
  • An intermediate section 24 extends between the proximal and distal ends.
  • the intermediate section 24 of each tube is collapsible as shown in Fig. 2A.
  • the collapsible nature of the tubes allows the cannula body 12 to contain a collection of tubes having cross-sections that, in combination, exceed the available space within the cannula body. For example, five collapsible tubes having diameters of 3mm, 5mm, 5mm, 10mm and 15mm might be positioned within a cannula body 12 having a diameter of 25mm or less.
  • the tubes 18 are constructed such that they will expand to the expanded position (Fig. IA) when an instrument is inserted into the instrument port 20 and advanced to the distal opening 22.
  • the instrument port 20 and distal opening 22 do not significantly collapse, but instead retain their open shape when the intermediate section 24 is in the collapsed position. This facilitates insertion of the instruments into the instrument ports 20, and also minimizes binding of the tubes as instruments are advanced towards the distal openings.
  • Suitable materials for the tubes 18 include thin walled or highly flexible polymeric materials.
  • the tubes may include a lubricious lining to facilitate advancement of instruments through the collapsed tubes.
  • the shapes of the instrument port 20 and distal opening 22 may be reinforced using resilient rings embedded in the tube material, or by thickened regions of the tubing material.
  • the cannula will preferably include a seal sealing the gaps between the tubes 18.
  • the seal may be a membrane 26 (Fig. 6) extending between each of the tubes 18 and circumferentially connected to the walls of the cannula 12.
  • a preferred membrane will be constructed to give play between the tubes such that movement of tube (e.g. from movement of an instrument shaft within that tube) does not cause others of the tubes to move.
  • the membrane can include loose/excess membrane material 28 between the tubes, or it may be highly elastic, or formed with pleats or bellows type structures 30 that allow for an increase in distance between adjacent tubes or between tubes and the surrounding wall of the cannula.
  • valves may be positioned within the tubes 18 so as to maintain insufflation pressure within the abdominal cavity during use of the system 10.
  • each port 20 may be equipped with a sealing system having a first seal providing for self- sealing of the port in the absence of a medical instrument within the port, and a second seal that creates a seal against the shaft of instruments passed into the port.
  • an annular seal 32 may be positioned most proximally, with a flap- or duckbill valve 34 located distal to the annular seal. During use, duck-bill valve remains closed when there is no instrument in the port 20. Instruments passed through the port 20 will pass between the flaps of the valve, thus releasing the seal provided by the valve.
  • the tubes 18 are placed within the cannula body 12 and the cannula body is placed such that the distal opening 16 is within a body cavity and the proximal opening 14 is positioned extracorporeally.
  • the surgeon will select an instrument needed to perform a procedure within the body cavity, and s/he will insert that instrument into the instrument port 20 of a tube 18 having an appropriate diameter, causing expansion of the tube as described above.
  • the tubes 18 may have color coding or other markings allowing the surgeon to easily determine which of the tubes is most appropriate for the selected instrument. Additional instruments are selected and likewise advanced through the most suitable ones of the tubes. As instrument changes are made throughout the procedure, different combinations of the tubes 18 are utilized.

Abstract

L'invention concerne un système d'accès médical qui comprend une canule (10) et une pluralité de tubes d'accès (18) placés dans la canule, chaque tube d'accès comprenant une ouverture proximale (20), une ouverture distale (22) et une section comprimée (24) entre les ouvertures proximale et distale. La section comprimée peut se modifier pour prendre une position élargie en réponse au passage d'un instrument dans la lumière. Les tubes présentent divers diamètres transversaux, ce qui permet à l'utilisateur de choisir d'utiliser une combinaison de tubes appropriée au protocole mis en œuvre. Les tubes pouvant être comprimés, le corps de la canule peut contenir un ensemble de tubes ayant des sections transversales dont la somme dépasse l'espace disponible dans le corps de la canule.
