Abstract

The invention provides a small-aperture artificial blood vessel preparation device based on electrostatic spinning. The device supplies power to a spinning solution injection device and a receiving device through a high-voltage power device, so that a static electric field is formed between a needle head in the spinning solution injection device and a receiving stick in the receiving device; furthermore, an injection sliding table control device is used for providing convenience for adjusting a distance and an angle between the needle head and the receiving stick; the structure of the receiving stick is different from the existing structure, as threads are formed on the receiving stick; and therefore, an artificial blood vessel with a spiral slot on the inner wall can be prepared, and a prepared small-aperture artificial blood vessel is very good in smoothness.

Description

technical field [0001] The invention relates to the field of preparation of artificial blood vessels, in particular to a preparation device for artificial blood vessels with internal spiral grooves. Background technique [0002] In recent years, the incidence of coronary heart disease, atherosclerosis and other diseases has been increasing day by day, and artificial vascular transplantation has attracted much attention as the main means of treating vascular diseases. Electrospinning square technology was invented by American Formhals (Formhals) in 1934 and has been widely used in the preparation of tissue engineering scaffolds. Artificial blood vessels made of electrospun fibers have high porosity and large specific surface area. , high fiber fineness and uniformity, large aspect ratio, etc. These excellent properties that cannot be obtained by traditional methods endow electrospun fibers with a wide range of application prospects. In addition, electrospinning technology...
