two groups of operation components 2 for alternately clamping the suture needles 3 are symmetrically arranged on two sides of the mounting plate 1, the two groups of operation components 2 are matched to suture the surgical incision 701 on the upper side of the bile duct 7 coated with the drainage tube 6 by using the suture needles 3 with both ends being needle heads, the defect that the needle inserting direction needs to be frequently adjusted in the suture process of the existing single-needle suture needle 3 is overcome, the operation is convenient, and the suture difficulty of the incision of the bile duct 7 under a laparoscope is reduced;
the auxiliary arm 5 with two groups of polymerization frames 507 is arranged, when the arc bottom plate 505 at the bottom end of the vertical rod 503 is propped against the top side of the drainage tube 6, the two groups of polymerization frames 507 are synchronously driven to gather together the two sides of the operation incision 701, so that the rear side suture needle 3 is used for suturing the operation incision 701, the top side of the drainage tube 6 is compressed downwards to improve the defect that the drainage tube 6 is easy to puncture in the existing suturing mode, the suturing is firmer, and the safety guarantee capability is stronger.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
