Problems solved by technology

[0003] Intestinal scissors are often used in gastrointestinal surgery. The existing surgical scissors are mainly composed of two simple scissors. During the scissors process, the hands must be clamped by one hand, which makes the hands prone to fatigue.
[0004] At the same time, although there were shadowless lights, it was difficult to accurately observe the corresponding organizational situation at that time
