Guide wire for aortic arch interventional therapy

Abstract

The invention discloses a guide wire for aortic arch interventional therapy. The guide wire is characterized by comprising guide wire heads (1) and a guide wire main body (2), wherein each guide wirehead (1) comprises a tip cap (3) and a shaping section (4); and the guide wire main body (2) is connected with the n guide wire heads (1), and n is a natural number larger than or equal to 2. According to the scheme of the guide wire, enough supporting force can be obtained on the wall of a blood vessel, the guide wire is not prone to falling off from the intersection of large-angle blood vessels,and an important role is provided in the channel construction process of interventional operation. Because the operation channel can be stably established, the ray time of patients and doctors is reduced, the general anesthesia time of the patients is shortened, the operation risk is reduced, and the vascular injury is reduced.

Description

technical field [0001] The present invention relates to medical equipment, and more particularly, to a guiding wire for interventional treatment of aortic arch. Background technique [0002] The invention patent belongs to the branch of interventional medicine. The guide wire is a consumable that is routinely used in interventional medical operations. It not only has the function of guiding the catheter into the blood vessels of the body, but also brings the catheter into the specifically selected target blood vessel or diseased blood vessel through the operation of professional doctors, so as to establish a surgical channel. In some cases, due to the difference in the nature and location of the lesion, the catheter needs to be replaced. At this time, the guide wire is an important tool necessary for replacing the catheter. [0003] For example, in the treatment of cardiovascular diseases, at present, interventional therapy is an effective treatment method in the treatment ...

AI Technical Summary

Problems solved by technology

If the surgical channel is unstable, it will cause the surgical catheter to fall off from the diseased blood vessel, which may cause local vascular endothelial damage, or cause rupture of the diseased blood vessel or vascular lesion (such as aneurysm, etc.), and the emboli in the blood vessel will fall off, aggravating the original disease, even life-threatening

4. The risk of surgical failure increases. If the interventional operation fails, the patient will be forced to switch from minimally invasive to open surgery for active treatment

However, since the incidence of cardiovascular and cerebrovascular diseases is positively correlated with the patient's age, and elderly patients cannot tolerate the trauma of open surgery, the failure of interventional surgery will cause most patients to lose their chances of surgery, which will seriously threaten their lives.

[0007] Many drawbacks of existing guide wires have caused huge risks and injuries to medical staff and patients, therefore, those skilled in the art are committed to developing a guide wire for aortic arch interventional treatment
