When the ligation position is not satisfied, it can be cut directly. The cutting force of the tissue is smaller than that of the titanium clip, and the tissue is not easy to be cut off.

(2) Convenient: compared with laparoscopic suture and ligation of tissue, the operation of snare ligation is simple, without other special instruments, and can shorten the operation time, especially for beginners to master and use;

(3) Economy: Snare is cheap, and its application can correspondingly reduce the consumption of endoscope cutting and closing device (Endo-GIA), which is expensive, and reduce medical expenses to a certain extent.
