1. An anastomosis clamp delivery system for deploying an anastomosis clamp (1), comprising a distal end (2), a middle flexible sheath (3), and a handle (4),
wherein the distal end (2) comprises a pulling cable (202) and a transparent cap (203), and the pulling cable (202) passes through the transparent cap (203) and is connected to the handle (4) via the middle flexible sheath (3); and
wherein the anastomosis clamp (1) is provided within the transparent cap (203), with the anastomosis clamp (1) being pressed against the pulling cable (202), so that the anastomosis clamp (1) to be released, being confined by the transparent cap (203), is in its cylindrical configuration,
when deploying the anastomosis clamp (1), a movement of the handle (4) drives the pulling cable (202) to push off the anastomosis clamp (1), such that the anastomosis clamp (1) is released from the delivery system;
wherein the distal end (2) further comprises a thrust ring (201); wherein
the thrust ring (201) is placed in the transparent cap (203);
the pulling cable (202) passes in a loop way and connects the thrust ring (201) and the transparent cap (203);
the pulling cable (202) that passes the thrust ring (201) and the transparent cap (203) is connected to the handle (4) via the middle flexible sheath (3);
an axial length of the thrust ring (201) is smaller than that of the transparent cap (203); and
the dis-continuous ring formed by the outer rings of the anastomosis clamp (1) abuts against the thrust ring (201).
