1. A bi-directional medical suturing device having a proximal end and a distal end, the device comprising:
a first needle having a tip directed toward a distal side, the first needle being movable in a longitudinal direction extending from the proximal end to the distal end;
a second needle being disposed more distal than the first needle, the second needle having a tip directed toward a proximal side, the second needle being movable in the longitudinal direction;
a first thread control member including a first holding portion being movable in a direction different from the longitudinal direction between a position where the first holding portion prevents a movement of the first needle and a position where the first holding portion does not prevent the movement of the first needle; and
a second thread control member including a second holding portion being movable in a direction different from the longitudinal direction between a position where the second holding portion prevents a movement of the second needle and a position where the second holding portion does not prevent the movement of the second needle,
the first thread control member and the second thread control member being arranged such that the first holding portion is located more distal than the first needle and more proximal than the second needle, and the second holding portion is located more distal than the first holding portion and more proximal than the second needle in a state where the first needle is located at the most proximal position and the second needle is located at the most distal position.
