Abstract

The utility model relates to a laparoscopic surgery clip applier. The laparoscopic surgery clip applier comprises a clamp device, a clamp rod device and a handle device. The handle device is connected with the clamp rod device, the clamp rod device is connected with the clamp device, and the clamp device comprises two clamps. The laparoscopic surgery clip applier is characterized in that one of the clamps is provided with a protecting lug structure. The laparoscopic surgery clip applier protects the inside as well as the outside of the lock catch of a ligature clip through the protecting lug structure of the clamp, avoids drop-off of the ligature clip due to that the lock catch of the ligature clip is pressed and scraped by blood vessels or tissues during clinical usage and can safely and effectively occlude the blood vessels and tissues and organs inside a human body.
