Figure 3 This invention discloses a suture instrument for an endoscopic surgical system, comprising a needle carrier platform 1, a suture needle assembly 2, a needle holder 3, and a needle pusher assembly. The suture needle assembly 2 is sleeved on one end of the needle carrier platform 1 along its length and is composed of multiple suture needle units 21 connected together. The needle holder 3 is movably inserted through the needle carrier platform 1. The suture needle assembly 2 is located between the needle carrier platform 1 and the needle holder 3. A needle holding half-ring clamp 31 is detachably connected to one end of the needle holder 3 near the suture needle assembly 2. A rotating assembly is also provided on the needle holder 3, which includes a rotating rod 35 and a needle separation plate 36. The needle holding half-ring clamp 31 and the needle separation plate 36 are spaced apart by the width of a single suture needle unit 21. The thickness of the needle separation plate 36 is set to match the gap between adjacent suture needle units 21, and its width is set to 1- 3mm, therefore, by rotating the rotating assembly, the separating needle plate 36 can be inserted counterclockwise downward into the gap between adjacent suture needle units 21, so as to separate a single suture needle unit 21 from the suture needle group 2, and the single suture needle unit 21 can be clamped by the needle holding half ring clamp 31 and the separating needle plate 36; the needle pushing assembly is connected to the suture needle group 2, and can push the suture needle group 2 to the gap between the needle holding half ring clamp 31 and the separating needle plate 36, so that the separating needle plate 36 can peel out the single suture needle unit 21.

The length of the needle pushing rotating shaft 12 is longer than that of the threaded sleeve 11, so that both ends of the needle pushing rotating shaft 12 can pass out of the threaded sleeve 11. A clamping piece 121 is fixed on one end of the needle pushing rotating shaft 12 close to the suture needle group 2, which is specifically provided as a clamp in the embodiment. The clamp can clamp the suture needle group 2, and then rotate the other end of the needle pushing rotating shaft 12 away from the suture needle group 2 to push the suture needle group 2 to translate forward on the needle loading experimental table 1.
