The invention discloses a titanium alloy drug release vascular stent, and relates to the field of vascular stents. The titanium alloy drug release vascular stent comprises a stent body, wherein the stent body is composed of a stent outer membrane and a stent inner membrane, the stent outer membrane and the stent inner membrane are made of a titanium alloy material and are of hollowed-out structures, the portion between the stent outer membrane and the stent inner membrane is filled with a soft body, and the outer surfaces of the left and right sides of the stent outer membrane are fixedly connected with outer protrusions. The titanium alloy drug release vascular stent has the advantages that an inner container is inflated to achieve the flexible expansion of the outer protrusions to bloodvessels, the expansion range is very wide, the adjustment is very convenient, the adjustment can be carried out according to the own situation of a patient, after the expansion is completed, inner protrusions are squeezed through the inner container, thereby squeezing medicine balls, so that drugs in the medicine balls are squeezed into the blood vessels, thereby achieving the drug therapy of theblood vessels, and the vascular stent not only can keep the blood flow of the lumens of the blood vessels smooth, but also can prevent restenosis of the blood vessels, and the practicability is high.
