The present application relates to a biological tissue transfer method for transferring a biological target tissue within the body, the method comprising: (a) attaching part of a first traction member to a first position which is different from a connecting position at which the target tissue is connected to other biological tissue (b) attaching part of a second traction member to a second position which serves as the apex of a triangle formed together with the connecting position and the first position that surrounds the target site (c) extending the first traction member in the direction from the connecting position to the first position, and extending the second traction member in the direction from the connecting position to the second position and (d) transferring the target tissue within the body by applying traction on the first traction member and the second traction member respectively.
