PROBLEM TO BE SOLVED: To provide an endoscope localization method.SOLUTION: An endoscope localization method includes the following steps: a localization assist device is attached to a machine arm, and a terminal end of a positioning mechanism of the localization assist device is overlapped with a spherical rotary center defined by the machine arm then an endoscope is inserted into the localization assist device and fixed the positioning mechanism of the localization assist device is removed, and a terminal end of the endoscope is overlapped with the spherical rotary center of the machine center and the endoscope is inserted into a conduit which is inserted into a body cavity to complete localization. By the above mentioned steps, the endoscope localization method of the present invention includes reducing a preparation time before operation, and improving accuracy of localization work. Furthermore, it is not necessary to cause the body cavity to be brought into contact with other tools, thereby reducing an infection risk.SELECTED DRAWING: Figure 1
