Abstract

The invention provides a rotating rod for 3D biological printing. The rotating rod is horizontally arranged and driven to rotate and is of a hollow structure, and at least one hole is formed in the surface of the rotating rod; in the 3D biological printing process, a nutrient solution passes through the hollow structure, and part of the nutrient solution penetrates out of the holes. The invention further provides a 3D biological printing platform which comprises the rotating rod and a nutrient supply system and can supply nutrients and a method for printing tubular tissue through the biological printing platform. Accordingly, the possibility that the tissue collapses due to the gravity influence is decreased, the novel method for achieving 3D biological printing of the tubular tissue and supplying the nutrients in the printing process is provided, and a wide application prospect is achieved.

Description

technical field [0001] The present invention relates to bioengineering manufacturing technology in the field of tissue engineering, more specifically, to a rotating rod for 3D bioprinting, a 3D bioprinting platform capable of supplying nutrients and a method for printing tubular tissue using the platform. Background technique [0002] Blood vessels are twists and turns in our body, which undertake the function of transporting necessary nutrients and discharging toxic waste, and escort the normal work of our body organs. It has been a difficult problem to develop new artificial blood vessels for a long time. With the advancement of aging process, abdominal The aortic aneurysm and vascular embolism are becoming more and more serious, the society's demand for artificial blood vessels is increasing, and various artificial blood vessels have also appeared one after another. With the development of modern bioengineering and material science, many new artificial materials and new pr...
