Definitions

  • a sutureless device and method for closing a tissue opening that minimizes the labor, skill, and cost typically required to properly close tissue lacerations.
  • Tissue wounds may be accidental or, a surgical incision and intentional.
  • animals also suffer from tissue wounds that require the skill of a veterinarian to close.
  • tissue wound closure The basic concept of tissue wound closure is to bring the two wound edges mechanically together in close alignment, both vertically and horizontally. When the wound edges are properly aligned, the wound heals more quickly, scarring is lessened and infections are decreased.
  • tissue wound closure is basic, the skills to properly close a tissue wound, using the current most common method of closure with sutures or tissue adhesive is done by a health care profession. It may take years to develop this skill. Access to health care providers is limited and often delayed requiring loss of time to get the repair done. In addition, the cost to get a wound repaired in the Emergency Department ranges anywhere from $500 up to $2,000.
  • the time period between the initial injury and the closure of the wound is also important. To lower the risk of infections it is essential that the wound be closed quickly. The longer the wound is left open, the more bacteria there is that enters the wound and begins to grow.
  • Several studies have shown that a tissue wound is best closed within six hours or less. Many doctors refer to this six-hour period as the“golden period.” Ideally a tissue wound should be closed within three hours. However, many times the patient is not near a medical facility or a doctor is not available for hours or even days. In addition, waiting times in Emergency Departments alone can be over 6 hours.
  • Previous wound closing methods included invasive and traumatizing methods such as sutures and staples. These methods required passing materials through the intact skin around the wound edges. These methods cause additional pain to the patient and increase the risk of infection. These methods, even if used by a skilled physician, may still cause pain and scarring caused by the sutures and staples themselves. It also requires expensive equipment and supplies that the general population do not have direct access to. To limit the pain, many doctors administer a local anesthetic. However, there are a number of adverse events that can occur from using these local anesthetics. These reasons are why such materials cannot be used by the general public and require a license and training.
  • Cyanoacrylates that can be purchased at the store are not suitable or approved for wound closures. They do not have an elasticity component built into the glue and are brittle causing the glue to separate before it is appropriately healed and the wound opens up, causing increased scaring.
  • sutureless devices included strips of fabric or surgical tape.
  • the wound is manually closed and the surgical tape is placed perpendicular to the tissue wound, preventing the wound from reopening.
  • surgical tape can only be applied to small, clean, shallow tissue wounds. These are not adjustable short of removing the entire bandage and replacing it. Removing the bandages may causes the wound to reopen again.
  • sutureless device that can be used easily by untrained users or by the individual themselves. That will allow the user to properly align the skin, and that can flex with the movement of the body.
  • the sutureless device should allow the user to use the device on jagged tissue wounds or contoured or rounded body parts.
  • the design and materials of this device will allow it to be manufactured in high volumes that allows it to be affordable and available to the general public. It will also not require the user to have special equipment, local anesthetic, or training in order to effectively use the product.
  • a principal object of the invention is to provide a sutureless device for easily closing an open tissue wound.
  • the invention easily closes an open tissue laceration, and to produce a device in such a way that it is easily accessible to all, including healthcare providers, veterinarians, and especially the general public.
  • the invention decreases the pain, infection and scarring associated with wound repair.
  • the invention significantly decreases the cost and inconvenience required to repair wounds that are found to be appropriate for closure by the device.
  • the object of the invention is to provide a device that allows the user to delicately close the tissue wound by properly aligning the two skin edges of the tissue wound both horizontally and vertically.
  • the device has flexible and expandable connections between each individual device to allow for irregular wounds or complex skin contour as well as the ability to flex with the movement of the body and adjust to the contour of the body.
  • Still another object of the invention is to provide a device that can be easily adjusted or readjusted for uneven or jagged tissue wounds.
  • the device will enable the individual to fine-tune the exact alignment of the wound for the best possible result in wound closure and decrease in scarring.
  • Another object the device is to allow it to be used as a single unit for a small laceration or as a group of attached units to close a larger or irregularly shaped laceration.
  • the present invention comprises two anchors that attach to opposing sides of an open tissue laceration.
  • the two anchors are connected together by means of a tie strip. As the two edges of the tissue wound are drawn together, the two anchors are brought together.
  • the tie strip ratcheting system prevents the anchors from separating and thus prevents the tissue wound from reopening.
  • a rack and pinion system is utilized.
  • the rack is located on the tie strip, and the pinion is located on a key.
  • a raised boss is located on one of the anchors that corresponds to an orifice on the bottom of the key.
  • the device may utilize a lever to control the distance between the two anchors.
  • the rack and pinion system converts the rotational motion of the key to the linear motion of the tie strip.
  • the movement of the tie strip causes the two anchors to come together and therefore closes the open wound.
  • the tie strip ratchet system prevents the anchor and the wound from reopening.
  • There is a release latch that can be lifted allowing the ratchet to be temporarily released such that you can adjust for potential over tightening, enabling you get the best possible wound closure.
  • a lever may be used to control the movement.
  • an optional lock may be utilized to prevent the movement of the tie strip.

Abstract

L'invention concerne un dispositif et des procédés sans suture pour fermer une ouverture de tissu qui réduit au minimum la main-d'oeuvre, le coût et l'habileté typiquement requis. L'appareil comprend deux ancres qui se fixent de chaque côté d'une plaie à tissu ouvert. Les deux ancres sont reliées l'une à l'autre par une bande de liaison ; la bande de liaison comporte une pluralité de dents et une crémaillère. Au fur et à mesure que les bords de la plaie et les éléments d'ancrage sont rassemblés, le système à cliquet sur la bande de liaison empêche les ancrages et le tissu enroulés de se refermer. Pour commander la distance entre les deux ancres, un système de crémaillère et de pignon et une clé ou un système de levier sont utilisés. La crémaillère est située sur la bande de liaison et le pignon est situé sur la clé.
