PROBLEM TO BE SOLVED: To provide an advancing/retracting assist tool for endoscope treatment devices configured that an operator can perform an operation of a treatment device without releasing a hand holding an insertion tube of an endoscope.SOLUTION: One end of an advancing/retracting assist tool 100 is connected to a treatment device insertion part 254 of an endoscope 200 by a first connecting member 120, and the other end is fixed to an insertion tube 220 of the endoscope 200 by a second connecting member 140. The treatment device 300 is inserted from the second connecting member 140, passes through a flexible tube 110 of the advancing/retracting assist tool 100 and a treatment device insertion channel 240 of the endoscope 200, and projects from a distal end of the insertion tube 220. An operator holds an operation part 260 of the endoscope 200 with the left hand, and holds a flexible tube 226 of the insertion tube 220 with the right hand, while holding a portion of the second connecting member 140 with the right hand. The operator can advance/retract the treatment tool 300 of the portion of the second connecting member 140, while operating the flexible tube 226 with the right hand.COPYRIGHT: (C)2014,JPO&INPIT【課題】術者が内視鏡の挿入部を把持する手を放すことなく処置具の操作を行えるように構成された内視鏡処置具の進退補助具を提供する。【解決手段】進退補助具100は、その一端が第1の連結部材120によって、内視鏡200の処置具挿入部254に接続され、他端が第2の連結部材140によって、内視鏡200の挿入部220に固定される。処置具300は、第2の連結部材140から挿入され、進退補助具100の可撓管110及び内視鏡200の処置具挿通用チャンネル240を通り、挿入部220の先端から突出する。術者は、左手で内視鏡200の操作部260を把持し、右手で第2の連結部材140部分を把持しつつ挿入部220の可撓管部226を把持する。術者は、可撓管部226を右手で操作しながら、第2の連結部材140部分の処置具300の進退操作を行うことができる。【選択図】図1
