PROBLEM TO BE SOLVED: To provide a medical clip device which enables a clip body and an operation wire to be easily connected to and separated from each other without use of a fracture structure, and which makes the number of components small.SOLUTION: A clip body and an operation wire are connected to and separated from each other by a hook structure. Thus, the risk of production of a broken piece by rupture is eliminated when the clip body and the operation are separated from each other. The clip body and a female part of ta hook are formed by one wire-like member to reduce a number of components. The opening and closing of the clip body and the contraction and expansion of the hook structure are interlocked with each other to improve operability.SELECTED DRAWING: Figure 1【課題】 破断構造を用いることなくクリップ体と操作ワイヤとの連結及び分離が容易に行え、かつ部品点数の少ない医療用クリップ装置を提供すること【解決手段】 クリップ体と操作ワイヤとを、ホック構造によって連結及び分離することで、クリップ体と操作ワイヤとを分離する際に破断による破片発生の虞をなくした。また、クリップ体とホック雌部とを一つの針金状部材で形成して、部品点数を削減すると共に、クリップ体の開閉とホック構造の縮拡とを連動させることで、操作性を向上させた。【選択図】図1
