  • Patent number: 6076255
    Abstract: This invention relates to a needle attached suture manufacturing method and apparatus capable of cutting a suture exactly at the same length, with a simple construction and high efficiency. A transport/holding device 42 holds a suture Y and transports the suture straight forward toward a needle swaging device 20 a distance corresponding to a predetermined target value. Thereafter, the suture Y is cut at a certain position to obtain a suture strand. The suture strand is then inserted in an insertion hole formed at the end of a needle and is swaged by the needle swaging device 20. As an altered method, after the suture Y is inserted in the insertion hole of the needle, the suture Y is cut at a position away from the end of the needle a predetermined target distance.
