The invention discloses an artificial blood vessel skeleton preparation device and method. The artificial blood vessel skeleton preparation device comprises a rotary charging barrel assembly, a skeleton rotating assembly and a translation driving assembly, wherein the skeleton rotating assembly is located below the rotary charging barrel assembly. During use, materials are injected into a first charging barrel and a second charging barrel respectively, a rotating seat is started to rotate, and the rotating shaft is driven to rotate, so that material filaments from the first charging barrel and the second charging barrel are knotted and laid on the surface of the rotating shaft; and the translation driving assembly drives one of the rotary charging barrel assembly and the skeleton rotating assembly to translate relative to the other one along the axis direction of the rotating shaft, so that the material wires are laid on the rotating shaft, and the skeleton is obtained. Compared with a knotless skeleton in the prior art, the skeleton produced by the invention is of a net-shaped pipe structure formed by knotting material filaments, so that the mechanical property is improved.
Description
technical field [0001] The invention relates to the technical field of artificial blood vessel skeleton preparation, in particular to an artificial blood vessel skeleton preparation device and method. Background technique [0002] Cardiovascular disease is a common disease that seriously threatens human life and health. The effective means of treating severe cardiovascular diseases is usually blood vessel transplantation. The best blood vessel for vascular transplantation is autologous blood vessel transplantation, but the source and quality of autologous blood vessel transplantation are difficult to guarantee to a large extent. Non-degradable materials are likely to cause restenosis and rejection of blood vessels when they are used in patients. [0003] In order to improve the long-term patency of artificial blood vessels, the current strategy is to use degradable materials as artificial blood vessels. Compared with non-degradable polymer materials, the mechanical propert...
