DEVICE FOR GUIDING INSERTION DEVICE TO BE INSERTED INTO BODY CAVITY AND SYSTEM FOR GUIDING INSERTION DEVICE TO BE INSERTED INTO BODY CAVITY

摘要

A device (10) for guiding an insertion device to be inserted into a body cavity has an insertion section (12) to be inserted into a body cavity (20) and also has a lumen (16) formed in the insertion section and functioning as a guidance section. The lumen (16) guides a thread (24) to a position on the opposite side of a target organ (22) in the body cavity (20) from an insertion hole into which the insertion section (12) is inserted, where the thread (24) functions as the insertion device for securing, in the body cavity (20), a space for treating the target organ (22).
