Tubular instrument and manipulation system

A manipulation system that collects a microscopic object, the manipulation system comprising:

• a tubular instrument including:
• a first tube part;
• a second tube part connected to an end of the first tube part;
• and
• a third tube part connected to another end of the first tube part, wherein a longitudinal direction of the third tube part intersects with a longitudinal direction of the first tube part, and is parallel to a longitudinal direction of the second tube part;
• a manipulator fitted with the tubular instrument;
• a sample stage on which a container for holding the microscopic object is mounted;
• a first microscope disposed above the sample stage;
• a second microscope disposed at a side of the sample stage;
• a first image pickup device that picks up an image of the third tube part provided parallel to a mounting surface of the sample stage, through the first microscope;
• a second image pickup device that picks up an image of the third tube part provided parallel to a mounting surface of the sample stage, through the second microscope;
• a third image pickup device that picks up an image of a side of the sample stage from a third direction that intersects with a first direction picked up by the first image pickup device and a second direction picked up by the second image pickup device;
• a display unit that displays a first image picked up by the first image pickup device, a second image picked up by the second image pickup device, and a third image picked up by the third image pickup device;
• and
• a storage unit that stores therein the first image, the second image, and the third image in an associated manner based on an image pickup time.
