Description
Technical Field
The invention relates to the technical field of thrombus removing instruments, in particular to a thrombus removing catheter and a thrombus removing device with the same.
Background
Arteries help to transport blood rich in oxygen and various nutrients to various parts of the body. When arteries in the lower extremities become occluded, sufficient blood or oxygen is not available, which is called Peripheral Arterial Disease (PAD). Peripheral arterial disease is due to the formation of lipid plaques on the vessel wall, the plaques being composed primarily of cholesterol, calcium and fibrous tissue. The plaque narrows or even completely occludes the arterial lumen, blood flow is reduced, and the lower limbs lack sufficient oxygen to maintain normal metabolism.
At present, still face very big challenge in PAD's thrombus clear away art, often will use the thrombus to clear away when patient's emergency intervention treatment, medical staff is carrying out the thrombus to patient and is clear away the operation time, holds accurate rescue time, and the lesion position is directional fast, practices thrift operation time, and high efficiency clears away the thrombus external. When the thrombus of the lesion blood vessel is removed, the blood vessel at the lesion position is protected.
In the current thrombus treatment scheme, two main treatment schemes are used, one is stent treatment, a stent is implanted at a position where thrombus lesion occurs in a blood vessel, the stent has the advantages of short treatment time and obvious clinical effect, the defect is that the stent is implanted into a foreign body, an antithrombotic drug needs to be taken for a long time after the stent is implanted, the stent cannot be taken out once being implanted, and only a bridging scheme is needed if thrombus is coagulated at the stent again. The second method is to embed a thrombolysis catheter at the lesion site where thrombus occurs, and continuously release thrombolysis medicine to the lesion site by using a medicine spray hole on the thrombolysis catheter, and has the disadvantages of slow thrombolysis effect and long period.
Based on the above-mentioned disadvantages of the conventional thrombus removal methods, mechanical thrombus removal methods will become the mainstream development of thrombus removal in the future. Because the blood vessels are layered one by one, each layer is tightly attached together, the mechanical method adopts the liquid medicine to impact the thrombus, so that the thrombus is broken, the damage to the target blood vessel is reduced as much as possible, and the blood vessel layer is prevented from being flushed to form an interlayer to cause complications.
However, in the conventional mechanical thrombus removal method, when the thrombus is impacted by the jet liquid, the jet liquid is ejected from the ejection port and directly impacts the inner wall of the blood vessel, which is likely to cause damage or stimulation to the inner wall of the blood vessel, thereby causing complications.
