Abstract

Third ventriculostomy is the preferred treatment for obstructive hydrocephalus, but the biomechanics of brain tissue damage caused by fiber endoscopes remains unclear. In this study, brain tissue material parameters were tested based on the Ogden model to simulate needle puncture mechanics, and replicated the entire fiber endoscope advancement process during third ventriculostomy. It was found that a smaller diameter fiber endoscope, a perpendicular puncture angle, and a faster puncture speed would decrease the damage of brain tissue caused by the fiber endoscope. This study provides valuable insights for optimizing the instrumentation and surgical process of third ventriculostomy.

纤维内窥镜穿透第三脑室造瘘术后脑组织损伤的生物力学研究。

第三脑室造瘘术是治疗梗阻性脑积水的首选方法，但纤维内窥镜引起脑组织损伤的生物力学尚不清楚。在本研究中，基于Ogden模型测试了脑组织材料参数，以模拟针头穿刺力学，并复制了第三脑室造瘘期间的整个纤维内窥镜推进过程。研究发现，直径较小的纤维内窥镜、垂直的穿刺角度和较快的穿刺速度可以减少纤维内窥镜中对脑组织的损伤。这项研究为优化第三脑室造瘘的器械和手术过程提供了有价值的见解。
