Definitions

  • Suturing instruments for assisting a medical practitioner in placing stitches during surgical procedures are useful, particularly in surgical procedures requiring the placement of secure and accurate sutures in difficult to access regions of the body, including internal body regions. Instruments and methods for suturing remotely are especially important in minimally invasive surgical procedures such as laproscopic and endoscopic procedures. In addition to helping to access remote regions of the body requiring suturing, suturing instruments may also allow the efficient manipulation of very small needles and the formation of small and precise sutures
  • a suture is attached to the center of a double-ended needle and can be passed between the two jaws. At least one end of the needle protrudes from one or the other jaw at all times. The protruding needle may become caught in tissue, a problem that is exacerbated in difficult to access regions and regions offering limited maneuverability, such as the subacromial space of the jaw. Similar devices are described in US 5,814,054, US 5,645,552, US 5,389,103, US 5,645,552, and US 5,571,090.
  • the diameter of the distal end of the device is less than 12 mm, less than 10 mm, less than 8 mm, or less than 6 mm.
  • the jaws at the distal end of the device may be appropriately scaled.
  • the first and second jaws may be less than about 30 mm long, less than 27 mm long, less than 25 mm, less than 20 mm long, etc.
  • the elongate neck region may have a diameter that is less than the diameter of the closed first and second jaws.
  • the jaws in the distal region are typically oriented so that they open and close perpendicular to the long axis of the device, however alternative configurations are possible.
  • the control may be biased (e.g., by a spring) so that return of the control to the relaxed position causes return of the tissue penetrator to the retracted position.
  • the tissue penetrator is triggered and fully extends after triggering, and returns automatically to the retracted position.
  • the tissue penetrator is controlled by the jaw control. For example, when the jaw control is activated to close tissue between the jaws, the tissue penetrator is activated. In some variations the tissue penetrator is extended when the pressure applied to the jaw control exceeds some threshold.
  • the tissue penetrator may be extended when the force applied to the jaw control exceeds about 2 lbs, about 5 Ib, about 81b, about 10 Ib, about 121b, about 151b, about 201b, etc.
  • the tissue penetrator movement is linked to additional pressure on the jaw control, so that continuing to squeeze the jaw control further extends tissue penetrator.
  • the tissue penetrator is "triggered” and fully extends after triggering, regardless of the amount of pressure applied to the jaw control above the threshold to trigger. Return of the tissue penetrator from the extended (tissue piercing) configuration to the contracted (at least partly within the jaw) configuration may be automatic or controlled (e.g., by decreasing the pressure on the jaw control).

  • the tissue clamping region typically includes a first jaw having first tissue-contacting surface, and a second jaw having a second tissue-contacting surface, wherein the tissue-contacting surfaces of the first and second jaws are substantially parallel when the tissue clamping region is opened.

  • the system may also include a suture attached to the suture attachment region of the shuttle.
  • the suture passer may be a continuous suture passer that includes a suture shuttle dock functionally connected to the second jaw and configured to releasably secure the suture shuttle.

Thus, when the tissue penetrator is extended from the first jaw, it meets the shuttle dock on the second jaw. As described above, this may be accomplished by coordinating the compound motion of the jaws as they are opened and closed.

Abstract

La présente invention concerne des éléments de passage d'une suture permettant de suturer un tissu d'une manière continue, en faisant passer à travers le tissu une suture fixée à une navette pour suture. Un élément de passage d'une suture peut inclure une première mâchoire, une seconde mâchoire et un pénétrateur de tissu qui peut se rétracter et s'étendre depuis la première mâchoire. Le pénétrateur de tissu peut présenter une région d'engagement de navette de suture, et la seconde mâchoire peut inclure un dock de navette. La navette de suture peut être transférée entre la première et la seconde mâchoires lorsque le pénétrateur de tissu s'étend depuis la première mâchoire et vient en prise avec la seconde mâchoire. Dans certaines variantes de l'élément de passage du tissu, l'une ou les deux mâchoires pénètrent dans le tissu. Dans certaines variantes, les mâchoires s'ouvrent en parallèle, permettant aux grandes régions tissulaires de se positionner entre les mâchoires.
