The application relates to an intelligent controllable super-deformation nose prosthesis, belonging to the field of plastic surgery medical instruments, which combines an inner concave hollow omega-shaped structure frame main body shell layer, a Janus interface outer coating and intelligent response materials to construct an anatomic-structure-function integrated nose prosthesis, performs micropore design and hydroxyapatite coating on the ventral side of the nose prosthesis to form a high-adhesion and high-stability nose prosthesis structure, performs smooth design and spermidine coating on the dorsal side of the nose prosthesis to inhibit envelope formation and avoid envelope constraint, combines the inner concave hollow omega-shaped structure design to realize super-orientation deformation performance, and the application of the intelligent response materials can realize non-invasive deformation adjustment through a temperature signal during or after surgery to meet the clinical requirements of intraoperative and postoperative fine adjustment. The nose prosthesis can be applied to plastic surgery, postoperative modification, repair and reconstruction scenes to meet higher-level medical and aesthetic requirements.

The present application relates to the field of biological medical materials and preparation technology, and specifically provides a 3D printing nose prosthesis based on a preset folding line sheet origami structure, the nose prosthesis is made of a biocompatible material, is integrally formed in a foldable sheet form through a 3D printing technology, and is provided with a plurality of preset folding line origami structures on the nose prosthesis, the nose prosthesis can be implanted into the body after being folded along the preset folding lines, and is unfolded along the preset folding lines after being implanted, so as to form a three-dimensional nose support structure; a preparation method of the 3D printing nose prosthesis based on the preset folding line sheet origami structure specifically includes five steps. Through the sheet structure and the preset folding line design, the present application significantly reduces the manufacturing and operation difficulty; the implantation can be completed through a small incision, so that the surgical incision and the infection probability are reduced; the folding and unfolding paths are controllable, and the unfolded form is stable; the material and the printing process selection range are wide, and the adaptability is strong; and the present application is beneficial to the realization of personalized customization and clinical popularization and application.
