The invention relates to the technical field of human bioengineering, in particular to a 3D printed tissue engineering stent with a specific form and structure. The 3D printed tissue engineering stentcomprises a structure body, wherein the structure body is composed of multiple sets of parallel mesh strips, the directions of the parallel mesh strips are different in different sets, and reinforcing ribs cross-connecting the mesh strips are arranged between the mesh strips. The 3D printed tissue engineering stent with the specific form and structure has the advantages that the mesh strips are connected through the reinforcing ribs distributed at intervals, so that the macroscopic shape of the stent forms a model of a physiological shape, and an auricle stent is prepared by adopting a 3D printing titanium alloy method, thereby preparing for improving an existing commonly used microtia external auricle reconstruction surgery, eliminating the trouble of cutting cartilago costalis through achest surgery, reducing the pain of a patient, simplifying the cumbersome steps of auricular stent preparation, reducing the workload and work intensity of a physician, reducing the operation difficulty, shortening the operation time, reducing the possibility of complications, providing more choices of surgical methods for the patient and his or her families, and having good application prospectsand market demands.
Description
technical field [0001] The invention relates to the technical field of human bioengineering, in particular to a 3D printed tissue engineering scaffold with a specific shape and structure. Background technique [0002] The basis of the treatment of congenital microtia is the reconstruction of the external auricle. The normal auricle is composed of thin skin soft tissue wrapped elastic cartilage support, has an elastic thin shell structure, and is composed of helix, antihelix, tragus, antitragus, earlobe, concha, triangular fossa, and scaphoid fossa Equal composition, convex and concave circles, complex shape, so auricle reconstruction is a difficult and complicated operation. At present, the main clinical surgical methods are mainly divided into two categories, one is dilator method ear reconstruction, including semi-inclusive method and all-inclusive method, and the other is non-expandable method, including Brent-Nagata method (also known as direct ear reconstruction). Bur...
