Threading Structure Patents (Class 112/224)
  • Patent number: 10052098
    Abstract: A surgical instrument includes first and second members configured to receive tissue therebetween. The first member is adapted to receive suture, the second member is coupled to the first member, and a grasper coupled to the second member engages the suture received by the first member. A method of passing suture includes loading suture into a first member of a suture passing surgical instrument, stabilizing tissue between the first member and a second member of the surgical instrument, passing suture through tissue via the first member of the surgical instrument, holding the passed suture via suture grasper of the surgical instrument, and removing the first member from the tissue. Advantageously, a novel bendable or deflectable needle may be utilized, e.g., in conjunction with the surgical instrument. The bendable or deflectable needle may have one or more unique configuration with respect to a suture slot defined in a distal portion thereof.

  • Patent number: 8733262
    Abstract: A needle thread passing device is capable of being constructed in a small size for easy storage. A needle receiving member 34 has a needle insertion hole 34c and a thread insertion slit 34e forming an angle with the needle insertion hole 34c. A needle threader member 42 is movable between positions away from and close to the needle receiving member 34 and has a needle threader pin 48b that can push a thread inserted through the thread insertion slit 34e into a needle eye 52a of a needle 52 inserted into the needle insertion hole 34c when the needle threader member 42 moves from the position away from the needle receiving member 34 to position close thereto. A cover 32 can move with respect to a main body 30 containing the needle receiving member 34. The needle threader member 42 is constantly biased toward the position away from the needle receiving member 34.

  • Patent number: 8028870
    Abstract: In an eyeless sewing needle, a periphery of an axial hole at the base end is heated to make a fibrous structure be a granular structure without directionality, and at least a part of a heat-affected zone made between the fibrous structure and the granular structure due to the heating is within a range that is three times the diameter of the sewing needle and that extends from an effective base of the axial hole towards the needlepoint. This allows provision of a flexible sewing needle so that the hole periphery can be processed while keeping a hard state at the position of the needlepoint slightly away from the axial hole.

  • Publication number: 20090266281
    Abstract: A new needle design is described. The eye of the needle is gapped in such a way that it can be threaded easily without having to insert the thread through the eye of the needle. Rather a thread is guided naturally into the groove of the gap and allowed to fall into the eye of the needle. The gap is fashioned in such a way as to prevent thread fallout during operation as well as fabric from getting caught in the gap.

  • Patent number: 4385575
    Abstract: Easy-threading sewing needles, in two embodiments, for hand needles and sewing machine needles are disclosed, as well as a method for making the easy-threading structure. The needles have eyes defined by sidewalls, one of which is slit along a plane which passes from the outer surface into the eye and divides the sidewall into an elongated inner clip member and a conforming retaining member. The clip member is mechanically spring-biased against the retainer but may be resiliently bent inward to open the slit by pressing a thread loop against the outside of the sidewall. The clip springs back against the mating surface of the retainer as soon as the thread enters the eye and the pressure is removed. The machine needle includes an off-center eye and the thread trap formed on the thinner sidewall, the point of the needle being formed off-center under the eye and a smooth shoulder projecting outward just under the entrance to the slit.
