The rapid growth of using ultrasound-guided interventional procedures, including biopsy and drainage, which considered painful procedures, leads to improving the practice cycle of ultrasound-guided procedures. Fabrication of low-cost tissue-mimicking phantoms that serve as a training tool medium for kidney needle biopsy procedures has dramatically overcome the drawbacks associated with these practices, such as reducing the number of miss lesions, medical errors, and recurrence rate as well as these phantoms are widely available and considered a good substitute for cadavers which were not always available and relativity expensive. However, several drawbacks are associated with current kidney phantom models, mainly the short shelf life and the high fabrication cost.
This study aims to fabricate a realistic three-dimensional static mature human kidney phantom from low cost and available material for training on ultrasound-guided interventional procedures mainly biopsy test; the material used to fabricate our model is the gelatin-agar mixture.
This model proved that it is a tissue-mimicking material by measuring their acoustic properties which nearly the same as real human kidney tissue.
The results of practicing interventional procedures on our phantom model showed good and easy uses for interventional procedures training as well as make it a preferable and economically affordable model.
包括活检和引流在内的超声引导介入操作的快速发展,这些操作被认为是痛苦的过程,这导致了超声引导操作实践周期的改善。制造低成本的组织模拟体模作为肾穿刺活检操作的训练工具介质,极大地克服了与这些实践相关的缺点,如减少漏诊病变的数量、医疗差错和复发率,并且这些体模广泛可得,被认为是尸体的良好替代品,而尸体并非总是可用且相对昂贵。然而,当前的肾脏体模模型存在一些缺点,主要是保质期短和制造成本高。
本研究旨在用低成本且可得的材料制造一个逼真的三维静态成熟人类肾脏体模,用于超声引导介入操作(主要是活检测试)的训练;用于制造我们模型的材料是明胶 - 琼脂混合物。
通过测量其声学特性,该模型证明是一种组织模拟材料,其声学特性与真实人类肾脏组织几乎相同。
在我们的体模模型上进行介入操作的实践结果表明,它对于介入操作训练具有良好且易于使用的特点,并且使其成为一种更可取且经济上可承受的模型。
