Embodiment 1

[0039] Such as Figure 1-3 And attached Figure 4 , 5 as shown in Figure 4 , the aneurysm 6 is located at the top of the arterial bifurcation, when the aneurysm clip treats the aneurysm at the top of the arterial bifurcation, press the handle 3 on the elastic clip body 1 to open the mouth of the aneurysm, and then place the opened semi-tubular The aneurysm clip is placed on the top of the artery 7 so that the open side of the aneurysm clip is aligned with the aneurysm mouth, the handle is released, the aneurysm clip seals the aneurysm mouth, and finally the handle 3 is removed from the round hole 2 on the aneurysm clip ,Such as Figure 5 As shown, the treatment process is completed.

Embodiment 2

[0041] Such as Figure 6 , 7 as shown in Figure 6 As shown, the aneurysm 6 at the top of the curved arterial bifurcation, when treating the aneurysm at the top of the arterial bifurcation, directly press the handle 3 on the elastic clamp body 1, so that the aneurysm clamp mouth is opened, and then the opened semi-tubular The elastic clip body 1 is placed on the top of the bifurcated artery, so that the open side of the aneurysm clip is aligned with the aneurysm mouth, the handle is released, the aneurysm clip seals the aneurysm mouth, and finally the handle 3 is lifted from the round hole 2 of the elastic clip body 1. remove, such as Figure 7 As shown, after the treatment process is completed, the entire clip body fits the outer wall of the artery, and is set according to the curvature of the blood vessel to better fit the outer wall of the blood vessel.

Embodiment 3

[0043] Such as Figure 8-10 as shown in Figure 8As shown, the aneurysm 6 is located on the curved artery. The difference from Example 2 is that the bending direction of the elastic clamp body 1 is different. As long as it is suitable for different blood vessel shapes, different degrees of curvature can be selected according to the actual situation. The elastic clip body 1 fits the actual blood vessel shape to the greatest extent. Such as Figure 9 As shown, installed in place, such as Figure 10 As shown, it belongs to the effect after the installation is completed.

Abstract

The invention relates to an aneurysm clip for treating artery sidewall and apex aneurysms with vascular branches. The aneurysm clip comprises an elastic clip body with a C-shaped section and handles which are inserted into an outer wall of the clip body through a plurality of round holes; the round holes are located in an outer wall of one end with an opening of the elastic clip body; round holes are formed in an outer wall of a free end at one side of the opening of the elastic clip body; two handles are arranged; each handle is omega-shaped; a semi-pipe-shaped structure of the aneurysm clip is adaptive to an artery outer wall, can be used for sealing the openings of the aneurysms very well and can also be used for reinforcing and protecting peripheral vascular walls. After the aneurysm clip is released, a lesion segment blood vessel can be protected from being further invaded by diseases and recurrence of the aneurysms is prevented. The handles of the aneurysm clip can be taken off after the aneurysms are released and peripheral brain tissues are not influenced; the volume is small and surgical injuries are further reduced; furthermore, damages, caused by surgical equipment, to peripheral tissues are reduced and influences, caused by surgeries, on patients are reduced to the minimum.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an aneurysm clip used for clamping an aneurysm on the side wall of an artery with blood vessel branches and on the top of a bifurcation. Background technique [0002] An aneurysm is a permanent dilated disease that occurs due to localized weakness of the arterial wall, which can occur on the side walls of the artery and at the top of the arterial bifurcation. Cerebral aneurysm is a peripheral aneurysm, which refers to a tumor-like protrusion produced by the limited expansion of the cerebral artery wall. The protruding aneurysm wall gradually becomes thinner under the continuous impact of blood flow and eventually ruptures and bleeds. Cerebral aneurysm rupture and hemorrhage have acute onset, severe symptoms, no obvious aura, and high mortality and disability rates. The treatment of cerebral aneurysms is mainly divided into surgical clipping and endovascular interve...
