Medical simulation training is widely used to effectively train for invasive medical procedures such as peripheral nerve blocks. Traditionally, accurate haptic training relies on expensive cadavers, manikins, or advanced haptic robots. Proposed herein is a novel concept for haptic training called the low-cost haptic force needle insertion simulator (LCNIS), which uses material fracture inside disposable cartridges to accurately replicate the force of inserting a needle into tissue. Cadaver and material fracture experiments were performed to develop and determine the accuracy of the LCNIS. The material testing showed that polycarbonate had the highest maximum needle puncture force of the materials tested, 9.85 N, and that fluorinated ethylene propylene had the lowest maximum puncture force, 0.84 N. The cadaver results showed that the error between the three peak forces in a cadaver and a cadaver mimicking cartridge was 1.00 N, 0.01 N, and 1.54 N. The standard deviation of these peaks was 0.60 N, 0.55 N, and 0.41 N. This novel method of haptic simulation can easily be adapted to recreate any type of force and, therefore, could be utilized to train for a wide variety of medical procedures.
医学模拟训练被广泛用于有效训练外周神经阻滞等有创性医疗程序。传统上，精确的触觉训练依赖于昂贵的尸体、人体模型或先进的触觉机器人。本文提出了一种称为低成本触觉针插入模拟器（LCNIS）的触觉训练新概念，它使用一次性墨盒内的材料断裂来准确模拟将针插入组织的力。进行了尸体和材料断裂实验，以开发和确定 LCNIS 的准确性。材料测试表明，聚碳酸酯的最大针穿刺力最高，为 9.85N，氟化乙烯丙烯的最大穿刺力最低，为 0.84N。尸体结果表明，尸体和尸体模拟墨盒中三个峰值力之间的误差为 1.00N、0.01N 和 1.54N。这些峰值的标准偏差分别为 0.60N、0.55N 和 0.41N。这种新的触觉模拟方法可以很容易地适应任何类型的力的重现，因此可以用于训练各种医疗程序。
