[0002] Vascular tissue closure forceps are typically used during surgery to clamp vascular clips onto vascular tissue. However, existing vascular tissue closure forceps are mainly single-clamp, making the process of clamping each vascular clip onto the blood vessel cumbersome and inefficient. Therefore, a double-clamp vascular tissue closure forceps is proposed to address these issues. Utility Model Content

Each V-shaped spring sheet is installed between two forceps heads in the same group, and one end of the two forceps heads is rotatably connected to the same end groove through a rotating shaft. A vascular clamp is placed between the two forceps heads in the same group.

[0015] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0018] Please see Figs. 1-3 As shown, a double-clamp vascular tissue closure forceps includes a first handpiece 1, a second handpiece 2, a traction rod 3, a hinge connector 4, a long catheter 5, a short curved tube 6, a U-shaped block 7, a clamp head 8, a steel wire 9, and a V-shaped spring plate 10. The first handpiece 1 is movably connected to the second handpiece 2 via the hinge connector 4, and one end of the long catheter 5 is connected to the top side of the first handpiece 1. One end of the steel wire 9 located inside the long catheter 5 is connected to one end of the traction rod 3 located at the top of the second handpiece. The two connecting parts at the other end of 9 are fixedly connected to the middle of the two V-shaped spring clips 10 respectively. Each of the V-shaped spring clips 10 is installed between the two clamp heads 8 in the same group, and one end of the two clamp heads 8 is rotatably connected to the same end groove 710 through a rotating shaft. A vascular clamp 11 is placed between the two clamp heads 8 in the same group. The short grooves are respectively opened on the end faces of the two ends of the U-shaped block 7, and a short bent tube 6 is fixedly installed in the middle of the U-shaped block 7. One end of the short bent tube 6 is threadedly connected to the threaded connection end 510 located at the other end of the long catheter 5.
[0019] Furthermore, the U-shaped block 7 has a channel 720 inside, and the two ends of the channel 720 are respectively connected to the inside of the two end grooves 710. The middle part of the channel 720 is connected to the inside of the short bent pipe 6. Another part of the steel wire 9 is inserted into the channel 720.
[0020] Furthermore, the bending angle of the short bend 6 is 120°.
[0021] Furthermore, the first handheld component 1 has a hole structure on one side of its top, and a pulling rod 3 extends into the hole structure.
[0022] Furthermore, the V-shaped spring sheet 10 is in a tensioned state by being pulled by the steel wire 9.
[0023] Working principle: The second hand-held part 2 moves to the right, causing the connecting rod 3 connected to it to move to the left. The connecting rod 3 drives the two V-shaped spring pieces 10 connected by the steel wire 9 to be in the closed state, which further drives the two sets of clamp heads 8 to be in the synchronous closed state. Since there is a vascular clamp 11 between the two clamp heads 8 in each set, the two vascular clamps 11 are clamped and fixed on the same blood vessel by means of the synchronous closed state of the two sets of clamp heads 8, so as to achieve the effect of hemostasis.
[0024] Compared with existing technologies, the difference lies in the fact that, based on traditional vascular fixation devices, a double-clamp structure is adopted, which is beneficial to simultaneously clamp and fix two vascular clamps 11 alternately on the same blood vessel, enhancing the strength of hemostasis and flow, making operation convenient, and solving the problem of low operation efficiency of a single clamped vascular clamp 11.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
