Claim:
A biological tissue transfer method for transferring within a body a stomach on which a treatment target site is present, the method comprising: (a) attaching part of a first traction member to a first position which is on the stomach and is different from the target site, and which is different from a connecting position at which an esophagus is connected to a thoracic diaphragm which supports the esophagus within the body; (b) attaching part of a second traction member to a second position which is on the stomach and is different from the target site, the connecting position, and the first position, and which serves as an apex of a triangle formed together with the connecting position and the first position, the triangle surrounding the target site, the triangle formed in part by a first straight line extending through the connecting position and the first position and a second straight line extending through the connecting position and the second position; (c) extending the first traction member along the first straight line in a first direction extending from the connecting position to the first position, and extending the second traction member along the second straight line in a second direction extending from the connecting position to the second position; (d) transferring the stomach within the body by applying traction on the first traction member along the first straight line in the first direction and by applying traction on the second traction member along the second straight line in the second direction; and (e) performing a surgical procedure on the target site after transferring the stomach.
