Embodiment 1

[0028] Such as figure 2 As shown, a minimally invasive venous vessel ligation device includes an arc-shaped wire needle 1, and the needle of the wire needle 1 is provided with a ring for fixing Figure 5 The winding groove 2 of the ligature wire 9 in the middle, the winding groove 2 is offered along the circumferential direction of the wire needle 1. Wire pin 1 is used with figure 2 The state shown is fed from the ligature 9 below the blood vessel 7 . to combine image 3 It can be seen that the wire needle 1 is also provided with a thread hooking groove 3, the thread hooking groove 3 runs through all the winding grooves 2, the thread hooking groove 3 is arranged along the length direction of the wire needle 1, and the thread hooking groove 3 is opened in the wire needle 1 on the side, with figure 2 The state of the wire needle 1 is the criterion, the outer arc of the wire needle 1 is the outside, and the inner arc of the wire needle 1 is the inside.

[0029] Such as ...

Embodiment 2

[0036] The difference between this embodiment and the first embodiment is that the wire needle 1 is also provided with a wire fixing hole, and the wire fixing hole is located on one side of the wire winding groove 2, and the wire winding groove 2 is a threaded groove in this embodiment. In actual use, the ligature 9 is passed through the fixing hole and then wound in the winding groove 2, so that the ligature 9 can be more stably fixed on the wire needle 1. In addition, the thread groove structure can make the ligature 9 more fit on the wire needle 1 , and further improve the fixing stability of the ligature 9 .

Embodiment 3

[0038]The difference between this embodiment and the first embodiment is that the length of the free end of the lead needle 4 is smaller than the length of the hook clip 5, so that the hook clip 5 can be pulled apart to form a clamping space.

Abstract

The present invention relates to the technical field of surgical instruments, in particular to a minimally invasive venous vessel ligation device, comprising a wire needle and a guide wire needle, an annular winding groove for fixing the ligature thread is arranged at the needle head of the guide wire needle, and a needle head of the wire guide needle is provided with There is a puller mechanism that transfers the ligature secured on the guide needle to the leader needle. The invention solves the problem of troublesome operation in the prior art.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a minimally invasive venous vessel ligation device. Background technique [0002] In the prior art, in the treatment of varicose veins and varicose veins, surgical therapy can be carried out if necessary. By cutting the skin, the ligature is sent into the skin tissue to encircle the blood vessel, and the blood vessel is ligated. [0003] In the prior art, there are usually two ways to ligate blood vessels. One is to directly use a curved hook needle to pierce under the blood vessel from the skin incision on one side of the blood vessel, and then pass through the skin incision on the other side of the blood vessel, so that the ligation thread covers the blood vessel. , and then tie the ligature thread to achieve vascular ligation. This method of ligation will bind the skin tissue between the two incisions, which is not only unsightly, but also leads to incomplete clo...
