PROBLEM TO BE SOLVED: To provide a surgery area securing device capable of stably securing a surgery area through a simple operation.SOLUTION: A surgery area securing device 10 comprises a body part 11 that includes plural wires arranged at intervals in order to form a truncated cone shape. The body part 11 has a maximum diameter that changes by applying force to the wires 14 and changing at least one of each attitude and each shape of the wires 14. When performing an endoscopic surgery, the device secures a surgery area by inserting the body part 11 into a body cavity in a state of reducing its diameter and then expanding the diameter of the body part 11 in the body cavity.COPYRIGHT: (C)2014,JPO&INPIT【課題】簡易な操作で、術領域を安定的に確保できる術領域確保装置を提供する。【解決手段】術領域確保装置10は、円錐台形を構成するべく間隔を開けて配置された複数の線材14を有する本体部11を備える。この本体部11は、線材14に力を加え、当該線材14の姿勢および形状の少なくとも一方を変更することで最大径が変わる。内視鏡手術を行う際は、この本体部11を縮径した状態で、体腔内に挿入した後、体腔内において本体部11を拡径し、術領域を確保する。【選択図】図2
