  • Publication number: 20140005719
    Abstract: An object of the present invention is to provide a revolutionary suture needle of exceptionally high marketability. The suture needle curves in the lengthwise direction of the needle body. A curved inner surface portion extending from a needle distal end (3) to a predetermined position P1 towards the basal end of a distal end portion (2) of circular cross section is furnished with frictional resistance reducing means for reducing the frictional resistance to less than that of a curved outer surface portion from the needle distal end (3) to the predetermined position P1 towards the basal end. The frictional resistance reducing means is a chamfered portion (4) chamfered at a surface passing through the needle distal end (3). The needle distal end (3) is furnished at a position coincident with the center axis L of the needle body (1).
