  • Method for manufacturing needle attached sutures and apparatus therefor
    Patent number: 5943759
    Abstract: This invention relates to a method for manufacturing a needle attached suture and an apparatus therefor. A needle attached suture is obtained by inserting a suture into an insertion hole formed in the end of a needle N which is held by a needle retaining unit 16 and by swaging the end of the needle with the suture. The method and the apparatus have been developed to accurately position the end of the needle for swaging with the suture to stabilize the swaging strength between the suture and the needle. Before the swaging, the needle is held by the needle retaining unit 16, and the end of the needle N is pushed to a certain position by a rod 99 or its equivalent. Thereby, the end of the needle N relative to the needle retaining unit 16 is accurately positioned.
