PROBLEM TO BE SOLVED: To provide a leg support tool for surgeon, which enables a surgeon to smoothly perform a long time continuing surgery, while reducing the surgeons fatigue during the surgery.SOLUTION: The leg support tool for surgeon includes: a base part 1 placed on a floor a rod-like support post 2 attached on the base part and a leg support part 6 attached on the support post so as to rotate and supporting a knee or shin of a surgeon. During surgery, the surgeon presses his/her knee or an upper part of shin and leans against the leg support part 6 and performs surgery in a comfortable posture. When the leg support part 6 is rotated, thereby the surgeon twists his/her body and receives a surgery instrument from a nurse, a leg contact part 602 can move in a front/rear direction when viewed from the surgeon as a user.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】外科医の手術中の疲労を軽減させながら、円滑に長時間に及ぶ手術を行えるようにする外科医用脚支持具を提供すること。【解決手段】床に置かれる台部1と、台部に取り付けられた棒状の支柱2と、支柱に回転可能に取り付けられ、外科医の膝又はすねを支持する脚支持部6とを備えている。外科医は手術の際、膝又はすねの上部を脚支持部6に押し当ててもたれかかり、楽な姿勢で手術を行う。脚支持部6が回転することにより外科医が体を捻って看護師から手術器具を受け取る場合、脚接触部602が使用者である外科医からみて前後方向に移動可能となっている。【選択図】図1
