Method for preparing biological-material integrally-implanted type ear cartilage bionic carriage

Abstract

The preparation method of biological material integrally-implanted ear soft bone bionic support includes the following steps: 1. preparing laminate image of reference auricle contour; 2. restructuring said image to obtain three-D entity model; 3. layering said three-D entity model to obtain two-D graph of every layer; 4. coding every layer two-D graph to obtain digital control code; 5. inputting digital control code of every layer two-D graph into quick forming machine; and 6. using the quick forming machine to make hierarchical piling and hierrarchical cutting according to the inputted digital control codes so as to obtain the invented ear soft bone support.

Description

technical field [0001] The invention relates to a preparation process of an integrally implanted ear cartilage bionic bracket, which belongs to the field of maxillofacial deformity repair, plastic surgery and rapid prototyping Background technique [0002] Microtia is a congenital deformity that affects physical and mental health. It is usually recommended to have plastic surgery before school age to reduce the psychological pressure of patients after entering society. The current repair methods are as follows: [0003] Wearable: A prosthesis that does not have to be inserted into the body. This prosthesis is not convenient enough to use because it needs to be worn. Due to poor fixation stability, the prosthetic ear deviates from the ideal position, making the decorative effect worse. Moreover, due to the difficulty in color matching, it is difficult to be completely consistent with the patient's skin. After long-term use, indicators such as color and toughness will chan...

AI Technical Summary

Problems solved by technology

Due to the fixed model design, this product cannot be customized for repair

Moreover, the appearance of its products is quite different from that of Chinese patients.

Its expensive cost can reach 50% to 60% of the entire repair cost, which is also unaffordable for Chinese patients

The artificial cartilage is made of polyethylene material, which has high hardness and insufficient elasticity

[0007] Methods such as silicone rubber and allograft cartilage sculpting have also been reported, prone to prolapse and immune problems

[0008] The disadvantage of the above method is that the shape or color of the artificial ear obtained is quite different from the original ear, which affects the wearing effect.

Imported materials are expensive and cannot achieve the symmetry of the restoration result with a healthy ear
