Definitions

  • the present invention relates generally to suturing devices and methods, such as for the percutaneous closure of body lumens and tissues by means of sutures, and particularly to a suturing guide assembly that facilitates passing sutures and needles through tissues to create stitches.
  • suturing devices are known in the art that puncture the skin with needles and percutaneously deliver sutures to the site.
  • endoscopic procedures where access to the work site is not readily available, the surgeon must use auxiliary devices to be able to grasp the suture strands and pass them through desired tissue.
  • PCT/IB2016/054972 describes a multiple-needle suturing assembly, which can be used to close a tissue puncture site with suture thread, such as a puncture site through the wall of a body lumen, or a percutaneous vascular puncture site at the distal end of a tissue tract.
  • the assembly can achieve closure wholly within the tissue tract leading to a puncture site and can be manipulated entirely from the portion of the device lying outside of the tissue tract.
  • the assembly can be used in various medical procedures, such as but not limited to, laparoscopic procedures, endoscopic procedures, arthroscopic procedures, and the like.
  • the present invention seeks to provide a suturing guide assembly, as described in more detail further below.
  • the guide of the present invention may be used in endoscopic or laparoscopic procedures, such as but not limited to, laparoscopic port closure, intra-abdominal suturing, closure of peritoneum or intra-abdominal knot-tying, hernia mesh fixations and many other surgical procedures.
  • the guide may be used to form any complex suture pattern, by passing needles of a multiple-needle suturing tool through holes of the guide, puncturing the tissue with the needles, passing the suture up through the tissue and guide, repositioning the suturing tool through other holes of the guide and repeating the steps of puncturing and passing the sutures up through the tissue and guide.
  • the guide of the invention comprises a stem having groups of needle lumens for inserting therein needles of a multiple-needle suturing tool, each of the groups comprising at least two needle lumens, and each of said needle lumens comprising an entry opening, a passageway and an exit opening in which each of said passageways connects one of the entry openings with one of the exit openings.

  • One group (designated group "A") of needle lumens 12 is used for the multiple needles of the suturing tool.
  • the group is a pair of needle lumens.
  • the needle lumens of at least one particular group are parallel with respect to each other for multiple-needle suturing tools in which all the needles are parallel with respect to each other (which is the case for a dual-needle suturing tool as in Figs. 5A-5B), and are not parallel for non-parallel multiple-needle suturing tools.
  • the suturing guide assembly 10 includes at least two groups of needle lumens, such as group "A" and group "B", for performing any desired stitch, such as but not limited to, cross, interweaved, complex stitches, etc.
