Embodiment

[0051] see figure 1 , the present embodiment provides a fixator 100, which is used to anchor the stent to the vessel wall 400 after the interventional treatment of aortic dissection and aneurysm, so as to effectively prevent the occurrence of type I endoleak and stent displacement; In addition, in the case where Type I endoleak has already occurred, the use of the fixator 100 to anchor the stent on the vessel wall 400 at the location of the endoleak is used for salvage and improvement.

[0052] In this embodiment, the holder 100 includes a transmission arm 120 and at least one three-dimensional helical fixed arm 110. The two ends of the three-dimensional helical fixed arm 110 along its length direction are the insertion end 111 and the transmission end, respectively, and the insertion end 111 is a tip. The insertion end 111 may be a conical tip, a rhomboid tip (eg, a Mitsubishi taper), a wedge-shaped tip, or the like. During anchoring, the insertion end 111 is used to pierce ...

Abstract

The invention provides a fixer and a fixation system, which belong to the field of medical equipment. The fixer includes a transmission arm and at least one three-dimensional helical fixation arm. The three-dimensional helical fixation arm has an insertion end and a transmission end along its length direction, and the transmission arm is installed on On the transmission end, the projection of the transmission arm along the central axis of the three-dimensional helical fixed arm falls into the area surrounded by the three-dimensional helical fixed arm. The fixation system includes a fixer, a delivery unit and an adjustment unit. The fixer can be delivered to the position to be fixed and pinned on the blood vessel wall to complete the fastening of the stent and the blood vessel wall, close the gap between the stent covering and the blood vessel wall, and improve the stability of the stent covering. Adhesion to the wall, while improving the anchoring force between the stent and the vessel wall, preventing the stent from shifting.

Description

technical field [0001] The present invention relates to the field of medical equipment, in particular, to a fixator and a fixation system. Background technique [0002] Aortic dissection or aneurysm is a clinically very dangerous vascular disease, which is a great threat to the life of patients. It is mainly caused by hypertension, arteriosclerosis, injury, infection, etc. Under the impact of blood flow, the tumor gradually appeared. After a long period of dilation of the aorta, the blood vessel wall becomes very fragile, and it is very easy to rupture. Once the aneurysm ruptures, it will inevitably cause a lot of bleeding. Some people call it the "bomb" in the body, and it is listed as one of the top 10 deadly diseases in Europe and the United States. one. With the aging of the population, the improvement of people's living standards and the continuous improvement of medical level, the incidence and detection rate of dissection and aneurysm have been increasing year by ye...
