Technical Field
The utility model relates to a vasodilatation sacculus with intercepting net.
Background
Cardiovascular diseases become one of the main causes of death of human diseases, such as aortic dissection, arterial embolism, aneurysm and the like in vascular diseases, the consequences of the vascular diseases are generally serious, and if timely and proper treatment is not adopted, the blood vessels can be ruptured and bleeding or infarcted, and the death rate is very high. For the treatment of such vascular diseases, open surgery and minimally invasive interventional therapy surgery are the main procedures at present, and the minimally invasive interventional therapy surgery has gradually become the preferred method for treating the vascular diseases because of the characteristics of no need of laparotomy, small wound, low requirement on the physical conditions of patients and the like.
Vasodilation is used primarily for the treatment of stenoses in vascular areas, which effectively dilates the diameter of the blood vessel and allows blood flow to be unobstructed. However, in the process of expanding the blood vessel, thrombus on the inner wall of the blood vessel falls off, and if the thrombus flows along with the blood, free thrombus is formed, which threatens the health of the body and influences the treatment effect.

Further, the conveying sheath tube is a flexible sheath tube and is used for wrapping the balloon catheter and intercepting the basket when necessary, so that the assembly can better pass through the blood vessel. The conveying sheath has good lubricating performance, and can effectively prevent the blood vessel from being damaged when moving along the guide wire path in the blood vessel. When the conveying sheath tube moves relative to the balloon catheter, the balloon and the intercepting net in the retraction state can be smoothly collected into the inner cavity of the conveying sheath tube, and the surface layer of the intercepting basket is coated with anticoagulant medicines, so that the influence of the operation of the instrument on blood flow is reduced, and the operation effect is better.
Furthermore, the intercepting net basket is a net basket woven by elastic metal wires, so that the intercepting net basket has a super-elastic characteristic and can quickly rebound to a specified shape after being compressed.
Further, the balloon catheter is a non-compliant balloon catheter.
Furthermore, the intercepting basket is arranged at the front end of the balloon on the balloon catheter, so that the intercepting basket and the balloon are closer to the opening of the transmission sheath after extending out of the transmission sheath.
Furthermore, the balloon catheter is provided with a positioning mark which can be detected by a detection device in an auxiliary manner at the front end of the intercepting basket, between the balloon catheter and the balloon and at the rear end of the balloon, so that the position of the working section can be well determined by the aid of the operation process, and the accuracy of the operation is guaranteed.
To sum up, the utility model discloses simple structure, convenient to use, collection vasodilatation in-process blood vessel inner wall thrombus that drops that can be accurate prevent that it from forming free thrombus, guarantee that patient's is healthy.
