1. A medical instrument, comprising
a flexible band body having a distal end and a proximal end;
a flexible first rod-shaped body having a distal end and a proximal end; and
a flexible second rod-shaped body having a distal end and a proximal end,
wherein
the distal end of the band body and the proximal end of the first rod-shaped body are connected,
the distal end of the first rod-shaped body and the proximal end of the second rod-shaped body are connected via a connecting portion,
the band body is more flexible than the first rod-shaped body and the second rod-shaped body,
the second rod-shaped body and the band body have a locking feature capable of tightening the band body to the second rod-shaped body at a desired position,
when tightened by the locking feature, the proximal end of the first rod-shaped body and the distal end of the second rod-shaped body are connected via a part of the band body, the connecting portion is inflected, and a loop having a desired size can be formed by the first rod-shaped body, the second rod-shaped body and the part of the band body,
the second rod-shaped body further has a feature for placing the rest of the band body along an outer surface of the second rod-shaped body in a direction from the distal end to the proximal end of the second rod-shaped body when tightened by the locking feature;
wherein the feature for placing the rest of the band body along the outer surface of the second rod-shaped body comprises a groove having a shape corresponding to the band body and being provided on the outer surface of the second rod-shaped body.
