摘要： The object is to seek a position for an insertion opening through which a treatment tool inserted inside a body cavity may reach an affected area while avoiding an obstacle. A first light emitting portion placed in an insertion portion applies light to an affected area inside a body cavity. A second light emitting portion placed in the insertion portion applies light to an inner wall of the body cavity toward the opposite side of the first light emitting portion. At this time, a light pathway on which the light from the first light emitting portion and the second light emitting portion will not strike the obstacle (e.g., an organ outside than the affected area, etc.) inside the body cavity is searched for. By making, in the position that the light from the second light emitting portion strikes, an insertion opening for inserting a treatment tool, the treatment tool can reach the affected area without interfering with the obstacle.

摘要翻译： 目的是寻找插入开口的位置，通过该位置插入体腔内的治疗工具可以到达受影响的区域，同时避免障碍物。 放置在插入部分中的第一发光部分将光照射到体腔内的受影响区域。 放置在插入部分中的第二发光部分将光线朝向第一发光部分的相对侧向体腔的内壁施加光。 此时，搜索来自第一发光部和第二发光部的光在其内部不会撞击体腔内的障碍物（例如，受影响的区域外的器官等）的光路径。 通过在来自第二发光部的光的位置上形成有用于插入处理工具的插入开口，处理工具可以到达受影响的区域而不会妨碍障碍物。
