PROBLEM TO BE SOLVED: To provide an absorption sheet base plate for surgical operation hardly causing a fold in a string member of an absorption sheet for surgical operation, and allowing the absorption sheet for surgical operation to be easily removed.SOLUTION: An absorption sheet base plate 1 for surgical operation holds an absorption sheet 2 for surgical operation including an absorption sheet body 3 and a string member 4. The base plate includes a base plate body 11 having a front part 16 and a back part. The base plate body 11 includes a sheet disposition part 17 located at the front part 16 to dispose the absorption sheet body 3. The front part 16 is provided with a plurality of string member support parts 18, 19 and 20 which the string member 4 is sequentially wrapped around. The string member support parts 18, 19 and 20 are disposed so that the angle (a) made between the base end side of the wrapped string member 4 from the string member support part 18 and the forward end side is an obtuse angle at least at the string member support part 18 corresponding to the most base end side of the string member 4.COPYRIGHT: (C)2014,JPO&INPIT【課題】手術用吸収シートの紐部材に折癖がつきにくく、手術用吸収シートが取り外しやすい手術用吸収シート台板を提供する。【解決手段】吸収シート本体3および紐部材4を有する手術用吸収シート2を保持するための手術用吸収シート台板1に関する。表面部16および裏面部を有する台板本体11を備える。この台板本体11は、表面部16に位置し吸収シート本体3を配設するシート配設部17を有する。また、紐部材4が順次巻き掛けられる複数の紐部材支持部18,19,20を表面部16に設ける。これら紐部材支持部18,19,20は、少なくとも紐部材4の最も基端側に対応する紐部材支持部18において、巻き掛けられた紐部材4の紐部材支持部18より基端側と先端側との角度aが鈍角になるように配置する。【選択図】図1
