Method for preparing individual integrally implantable auricular cartilage support by fast veneer gluing

Abstract

The invention relates to a method for preparing an individual integrally implantable auricular cartilage support by fast veneer gluing. An auricle reconstructed by an existing method is greatly different from an original ear in appearance or color, and wearing effects are affected. The method includes the steps: firstly, acquiring a slab image of the appearance of a reference auricle and extracting a cartilage contour; secondly, acquiring a three-dimensional solid model of an auricular cartilage; thirdly, additionally arranging a support capable of stably fitting a skeleton and ensuring a correct angle of a repaired auricle; fourthly, additionally arranging a drainage duct; fifthly, layering the acquired three-dimensional solid model to obtain two-dimensional graphs of layers and inputting the two-dimensional graphs to a fast forming machine; and finally, performing layered accumulation or layer-by-layer cutting by the fast forming machine to obtain the auricular cartilage support. The artificial auricular cartilage support prepared by the method is subcutaneously implanted, so that the vivid auricle symmetric to a healthy auricle can be obtained.

Description

technical field [0001] The invention relates to a preparation method of an integrally implanted ear cartilage bionic bracket, belonging to the fields 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 undergo 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 reconstructed auricle obtained is quite different from that of 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
