PROBLEM TO BE SOLVED: To provide a suture needle for pressurizing and stopping bleeding in a uterus capable of safely performing a surgery of pressurizing and stopping bleeding in the uterus.SOLUTION: A suture needle 1 for pressurizing and stopping bleeding in a uterus includes: a suture needle 10 that includes a trunk part 14 linearly extending in a lengthwise direction D1, and a puncture part 15 provided at a tip end in the lengthwise direction D1 of the trunk part 14 and puncturing into the uterus； and a suture thread 13 attached to a base end 17 in the opposite side of the puncture part 15 in the suture needle 10. The puncture part 15 bulges toward the tip end side in the lengthwise direction D1 and is formed into a spherical surface whose radius in a connecting part with the trunk part 14 is substantially same as a radius of the trunk part 14.SELECTED DRAWING: Figure 1【課題】子宮を圧迫止血する手術を安全に行うことが可能な子宮圧迫止血用縫合針を提供する。【解決手段】子宮圧迫止血用縫合針１は、長さ方向Ｄ１に直線状に延びる胴部１４と、胴部１４の長さ方向Ｄ１の先端に子宮に突き刺すために設けられた穿刺部１５と、を有する縫合針１０と、縫合針１０における穿刺部１５と反対側の基端部１７に取り付けられた縫合糸１３と、を備える。穿刺部１５は、長さ方向Ｄ１の先端側に向かい膨出すると共に胴部１４との接続部における半径が胴部１４の半径と実質的に同一である球面に形成されている。【選択図】図１
