To provide a holding jig for holding an instrument used for a surgery or a surgery training, in which the instrument can be rotated with a fixed one point as a center of the rotation and with two directions orthogonal to each other as axial directions of the rotation even if the structure is simplified.SOLUTION: A holding jig 1 includes: a holding member 4 for holding instruments 2, 3； a supporting member 5 for rotatably supporting the holding member 4； and a supporting member 6 for rotatably supporting the supporting member 5. The axial direction of the rotation of the holding member 4 and the axial direction of the rotation of the supporting member 5 are orthogonal to each other. The holding member 4 comprises: a holding part 4a that holds a part to be held 3a of the instrument 3 having an axial center CA2； a holding part 4b that holds a part to be held 2a of the instrument 2 having an axial direction CA1； and a connection part 4d for connecting the holding part 4a and the holding part 4b. The intersection point C of a center line CL1 that becomes a center of the rotation of the holding member 4 and a center line CL2 that becomes a center of the rotation of the supporting member 5 is arranged on extension lines EL1, EL2 of the axial centers CA1, CA2.SELECTED DRAWING: Figure 4【課題】外科手術または外科手術の訓練で使用される機器を保持する保持具において、構成を簡素化しても、固定された一点を回動の中心点にするとともに互いに直交する２方向を回動の軸方向とする機器の回動が可能な保持具を提供する。【解決手段】保持具１は、機器２、３を保持する保持部材４と、保持部材４を回動自在に支持する支持部材５と、支持部材５を回動自在に支持する支持部材６とを備え、保持部材４の回動の軸方向と支持部材５の回動の軸方向とは直交している。保持部材４は、軸心ＣＡ２を有する機器３の被保持部３ａを保持する保持部４ａと、軸心ＣＡ１を有する機器２の被保持部２ａを保持する保持部４ｂと、保持部４ａと保持部４ｂとを連結するための連結部４ｄとを備えている。保持部材４の回動の中心となる中心線ＣＬ１と、支持部材５の回動の中心となる中心線ＣＬ２との交点Ｃは、軸心ＣＡ１、ＣＡ２の延長線ＥＬ１、ＥＬ２上に配置されている。【選択図】図４
