Detailed Description

As shown in fig. 1, a multifunctional surgical instrument comprises a fixed handle 1, a movable handle 2, a connecting rod 3, a pull rod 4 and a binding clip 5, wherein two ends of the connecting rod 3 are respectively connected with the fixed handle 1 and the binding clip 5, the connecting rod 3 is of a hollow structure, the pull rod 4 is partially arranged in the hollow structure of the connecting rod 3, one end of the pull rod 4 is connected with the binding clip 5 through a transmission mechanism, and the other end of the pull rod is fixedly connected with the movable handle 2. As shown in fig. 2, the fixed handle 1 is connected with the movable handle 2 through a shaft, a first limit post 6 and a second limit post 7 are arranged on the fixed handle 1, and the first limit post 6 and the second limit post 7 are respectively positioned at two sides of the movable handle 2. The first limiting column 6 and the second limiting column 7 limit the relative movement distance between the movable handle 2 and the fixed handle 1, and the tissue is prevented from being accidentally injured due to overlarge relative movement between the movable handle and the fixed handle.

As shown in fig. 3, the binding clip 5 includes a first binding clip 13 and a second binding clip 14, the first binding clip 13 and the second binding clip 14 are fixed on the connecting rod 3 through a positioning shaft 15, the first binding clip 13 and the second binding clip 14 respectively include a grabbing portion 8 and a shearing portion 9, the grabbing portion 8 is far away from the positioning shaft 15, and the shearing portion 9 is close to the positioning shaft 15. The grasping portion 8 of the first binding clip 13 and the grasping portion 8 of the second binding clip 14 are respectively provided with meshing teeth 11 which are matched with each other on the opposite end surfaces. Mouse teeth 12 which are matched with each other are respectively arranged at one ends, far away from the shearing part 9, of the grabbing part 8 of the first tong head 13 and the grabbing part 8 of the second tong head 14. A transition part 10 is arranged between the grabbing part 8 and the shearing part 9, and the length ratio of the grabbing part 8 to the transition part 10 to the shearing part 9 is 2:1: 1. By arranging the transition part 10, the situation that the shearing part 9 accidentally injures the tissue when the grabbing part 8 grabs the tissue is avoided.

As shown in fig. 4, the transmission mechanism includes a first connecting rod 16 and a second connecting rod 17, the first connecting rod 16 and the second connecting rod 17 are arranged in a crossing manner, one end of the first connecting rod 16 is connected with the end of the first binding clip 13, the other end is fixedly connected with the key head 18, one end of the second connecting rod 17 is connected with the end of the second binding clip 14, the other end is fixedly connected with the key head 18, and the pull rod 4 is fixedly connected with the key head 18.
