PROBLEM TO BE SOLVED: To provide a non-uniform pressure distribution to a tissue which cannot be compressed by sufficiently engaging with a small blood vessel or is compressed, and therefore, one of the conventional surgical clips. Or it aims to mitigate or overcome two or more problems. SOLUTION: A surgical clip is a first leg member having an inner surface, an outer surface, and first and second side surfaces, and the inner surface of the first leg member has a concave curve. A second leg member having a member, an inner surface, an outer surface, and first and second side surfaces, and a second leg member having a convex curve on the inner surface of the second leg member. Includes at least one first tooth extending from the first side of the inner surface of the leg member and a first channel defined between the first side surface and the inner surface of the first leg member. be able to. The first and second leg members can be configured to move between the open and closed forms, in which at least one first tooth is received within the first channel. .. [Selection diagram] Fig. 17【課題】現在の外科用クリップは、小血管と十分に係合して圧迫することできない、又は圧迫された組織に不均一な圧力分布を与ることがあるため、従来における外科用クリップの１又は２以上の問題を軽減又は克服することを目的としている。【解決手段】外科用クリップは、内面、外面、及び第１及び第２の側面を有する第１の脚部材であって、この第１の脚部材の内面が凹状の湾曲を有する第１の脚部材と、内面、外面、及び第１及び第２の側面を有する第２の脚部材であって、この第２の脚部材の内面が凸状の湾曲を有する第２の脚部材と、第２の脚部材の内面の第１の側辺から延びる少なくとも１つの第１の歯部と、第１の脚部材の第１の側面と内面との間に定められた第１のチャネルと、を含むことができる。第１及び第２の脚部材は、開放形態と閉鎖形態との間を移動するように構成することができ、閉鎖形態では、少なくとも１つの第１の歯部が第１のチャネル内に受け入れられる。【選択図】図１７
