Definitions

  • the present invention relates to an all-suture anchor, and more particularly, to a folder type suture anchor for re-establishing soft tissues such as ligaments, tendons, and articular capsules in bone.
  • Ligaments are elastic fibrous connective tissue that has elasticity and is primarily located in joints and connects bones with bones.
  • the ligaments also stabilize or limit the motion of the joints by tightly resisting the movements of the joints, which makes them liable to damage.
  • Ligament injuries include sprains, torsion, tearing, and tearing.
  • Ligament breakage occurs mainly at the site where the ligaments and bones are joined. Therefore, most of the surgery to reseal the broken ligament is in the form of fixing the ligament to the bone.
  • Suture anchor in traditional tradition as described above has the advantage of having a relatively strong fixing force.
  • an all-suture anchor has been developed that is somewhat weak in fixation but can reduce bone damage.
  • Pre-sealed anchors use woven sutures, which generally consist of a thick suture (straight or braided or hollow fiber) portion and a thin suture portion connected thereto.
  • the type of thick suture for fixing used in electric suture anchors is direct irradiation (knot), knitting yarn or hollow fiber.
  • the mechanism of action depends on the various types of coarse sutures used in the electric suture anchor and the condensation method of each coarse suture.
  • the form of direct irradiation has a disadvantage of being difficult and difficult to manufacture because we make the required shape while weaving the yarn in the manufacturing process.
  • Hollow fiber shape is easy to manufacture, but there is a disadvantage that the outer edge of the hollow yarns are not condensed efficiently during condensation.
  • the knitting type has an advantage that the area is large, so that the condensation efficiency is excellent and the manufacturing is easy.
  • the conventional knitting type has a disadvantage in that the fixing force is somewhat reduced because the anchor portion formed by condensation is formed due to the thin thickness but the thickness is large.
  • An object of the present invention has been made in view of the above points, and in particular, to provide a folder-type electric suture anchor that can further increase the fixing force for the electric suture anchor of the knitting type with good condensation efficiency.
