AI Technical Summary

Technical Problem

The material texture of the existing rib cartilage engraving training model is very different from that of the human rib cartilage, which makes it impossible for doctors to effectively simulate the operating environment during surgery, and the practice effect is not good.

Method used

A three-dimensional model of rib cartilage was constructed using CT scanning technology, and a highly simulated rib cartilage engraving training model was printed using the agilus series materials through SLA 3D printing technology.

Benefits of technology

The high authenticity of the rib cartilage engraving training model is achieved, and the appearance and texture are close to the real human rib cartilage, which improves the authenticity and reliability of surgical training and reduces the possibility of human error.

Abstract

The invention discloses a costal cartilage sculpture training model related to microauricular malformation reconstruction and a manufacturing method of the costal cartilage sculpture training model. According to the method, the costal cartilage carving training model can be directly printed in one step from the digital model through the precise CT scanning and the advanced three-dimensional reconstruction technology in combination with the SLA 3D printing technology. The advantage of this one-step molding is that it avoids the complexity and errors of multi-step assembly and joining that may occur in conventional manufacturing methods. And each model is integrally formed, so that the accuracy of the model and the integrity of the structure are ensured. The method not only improves the production efficiency, but also reduces the possibility of human errors, thereby improving the reliability and training effect of the model. Doctors and surgeons can use these models for surgical simulation and training without having to worry about the inaccuracy or untrueness of the models.
