摘要： The problem that a metal wire joined integrally to a hole formed in a proximal end face of a medical suture needle is susceptible to bending damage is reduced.A suture needle A has a blind hole 5 which is formed in a proximal end face 3, inserts the end of a wire 10 thereinto, and joins the wire 10 thereto by caulking, and a counterbore 6 which is formed on the proximal end face 3 side of the blind hole 5 and has a dimension D at least in the proximal end face 3 larger than a dimension d of the blind hole 5 and a depth L smaller than a depth of a caulked portion with respect to the blind hole 5. A suture needle with wire inserts the end of the wire 10 into the blind hole 5 to caulk the outer circumference of the suture needle corresponding to the blind hole 5, thereby integrally joins the wire 10 thereto.

摘要： A simple fabrication method for a suture needle coated with silicone, which prevents silicone from penetrating into a hole is provided.The fabrication method for a suture needle coated with silicone includes the steps of: facing a hole 12 formed at a base of an eyeless suture needle 10 downward and supporting it with a gripping unit; and coating silicone on the entire outside of the eyeless suture needle, making the inner wall of the hole be the base material of the eyeless suture needle. Consequently, the silicone can be prevented from intruding into the hole by a simple method.

摘要： Provided is a suturing needle, which can be reliably held by a needle holder, which can transmit a high thrust, and which can reduce the fear of damaging a patient and the deformation when a strong force acts. The suturing needle has a representative constitution including a needle tip portion (1) having a needle tip (1a) for piercing the tissues, a tapered portion (2) continuing to the needle tip portion (1), a trunk portion (3) continuing to the tapered portion (2), and a thread attaching portion (4) continuing to the trunk portion (3) for connecting the suturing thread. The suturing needle is characterized in that the needle tip portion (1) is formed to have a circular section continuing to the sharp needle tip (1a), an angular section continuing to the sharp needle tip (1a), a circular section continuing to the blunt needle tip (1a) or an angular section continuing to the blunt needle tip (1a), in that the tapered portion (2) is formed to become gradually thicker from the needle tip portion (1) to the trunk portion (3), in that the trunk portion (3) is formed to have a substantially triangular section, the upper face of which is formed of a wave shape having at least two ridges and the slopes of which are formed of two flat faces, in that the trunk portion (3) is also formed to have relations of R1≧R2≧R3, when a peak (5) or the joint portion between the two flat faces has a diameter of R1, when the crest of the ridges has a roundness of R2, and when a valley (7) has a roundness of R3, in that the valley (7) is formed to correspond partially to the peak (5), and in that the thickness becomes continuously larger from the tapered portion (2) to the trunk portion (3).
