[PROBLEMS] When performing the sternum suturing needle with wire, in conjunction with the movement of the needle easily rampage the rear end of the wire, there is a risk of causing infection during surgery. The thoracic cavity is narrow, needle operation requires skill. Sternum needles want thicker needle as possible, but invasion increases. Since the wire must be raised twisting with a strong force, it can not be thin. Stump of the needle rear end if there is no tapered portion, there is a possibility of bleeding. The tapered portion of the wire is also essential for the smooth passing. Conventional needle, needle tip after penetration, difficult visibility. The intercostal suture, it is necessary to avoid damage to the internal mammary artery, it is necessary to package that combines a blunt needle and sharp needle. A wire fastening portion is a material of stainless steel or titanium with a diameter of 0.7mm~1.0mm, the wire introduction part of 50mm~300mm from the edge of the one end portion to the diameter 0.30mm~0.55mm The slimming process, the portion of varying diameter, and a tapered shape which varies gently sloping. Needle portion is connected to the wire stump that was processed thin. the shape of the needle rear end wire to connect was a tapered shape. The shape of the needle part, it was the tip portion 15mm~20mm a linear shape. Cutting surface shape of the needle tip straight portion, by looking at the shape of the "V" from the left, to obtain a shape that is inclined to the left side. The needle tip for intercostal suture, it was Sakidon shape. Also is a sharp needle, the necessary number of the plurality are combined in a single surgery and blunt needle and packaged in sterile packaging. BACKGROUND.【課題】針付ワイヤーで胸骨縫合を行う際、針の動きに連動してワイヤーの後端が暴れやすく、術中に感染を起こす危険がある。胸腔内は狭く、針の操作は熟練を要する。胸骨針は出来るだけ針を太くしたいが、侵襲が大きくなってしまう。ワイヤーは強い力で捩じり上げなければならないので、細くできない。針後端の断端はテーパー部分がないと、出血する可能性がある。またワイヤーのテーパー部分もスムーズな通過には不可欠である。従来型の針は、貫通後に針先端が、視認しにくい。肋間縫合には、内胸動脈の損傷を避ける必要があり、鈍針や鋭針を組み合わ
