AI Technical Summary

⚠Technical Problem

Existing training models differ greatly from the performance characteristics of human brain tissue, have complex structures, and unclear feedback, resulting in unsatisfactory training effects. This is especially true for young doctors, as puncture surgery is difficult and prone to errors.

⚗Method used

A simulated brain tissue and lateral ventricle were prepared using self-healing hydrogel material, combined with conductive cloth and indicator light system to simulate real feel and provide puncture angle feedback. The lateral ventricle puncture model was constructed using 3D printing technology.

🎯Benefits of technology

It improves training effectiveness, reduces costs, can be reused multiple times, and enhances puncture accuracy and training efficiency through the indicator light system.

Abstract

The present application relates to the technical field of medical teaching aids, and provides a lateral ventricle puncture model for training and a preparation method therefor. The lateral ventricle puncture model for training of the present application comprises: a skull module and a brain module. The brain module comprises simulated brain tissue and a simulated lateral ventricle, the interior of the simulated lateral ventricle is a cavity structure, and the simulated lateral ventricle is filled with simulated cerebrospinal fluid, wherein the simulated brain tissue and the simulated lateral ventricle are made of a self-healing hydrogel material; and the self-healing hydrogel material comprises the following components in percentage by weight: 8-10% of a total of acrylic acid, N-isopropylacrylamide and dopamine acrylamide, 0.1-0.3% of oxidized hydroxypropyl methylcellulose, an initiator, and the remainder being water. The lateral ventricle puncture model for training has a material having properties close to those of human brain tissue, can better simulate the tactile sensation during puncture, and improve the training effect; and has an excellent self-healing property, can be reused multiple times, and reduce costs.
