我们开发了一种驱动器驱动的脉冲水射流（ADPJ）装置，以实现最大程度的病变剥离和最小的正常结构损伤风险。尽管具有独特的解剖特征，但存在组织弥散扩散的风险；然而，目前还没有确定的方法来量化色散。因此，本研究旨在评估与分散相关的因素，并提出一种简单的实验方法，使用分光光度法来评估湿场中的分散程度。亚甲基蓝染色的脑幻影明胶浸泡在蒸馏水溶液中，用ADPJ解剖。将分散的明胶溶液搅拌加热溶解。用分光光度法测定了溶液的吸光度。首先，构建参考标准曲线，确定吸光度与明胶分散量之间的关系。观察到明显的比例相关性，这表明吸光度测量可以帮助评估色散的数量。利用这种方法，我们发现高的解剖力、不足的吸力以及喷嘴尖端与目标之间不适当的距离与分散增加有关。这种方法可能构成一个通用的和可靠的方法来评估分散和帮助发展的手术装置。
We developed an actuator-driven pulsed water jet (ADPJ) device to achieve maximal lesion dissection with minimal risk of normal structural damage. Despite the unique dissection characteristics, there is a risk of dissemination of tissue dispersion; however, there is no established method to quantify the dispersion. Hence, this study aimed to assess the factors associated with dispersion and propose a simple experimental method using spectrophotometry to evaluate the degree of dispersion in a wet field. Methylene blue-stained brain phantom gelatin was immersed in a chamber with distilled water solution and dissected with an ADPJ. The dispersed gelatin solution was stirred and warmed to dissolve. The absorbance of the solution was measured spectrophotometrically. First, a reference standard curve was constructed to confirm the relationship between the absorbance and the amount of the dispersed gelatin. A clear proportional correlation was observed, which indicated that absorbance measurements can help evaluate the amount of dispersion. Using this method, we revealed that a high dissection force, insufficient suction, and inappropriate long distance between the nozzle tip and the target were associated with increased dispersion. This method might constitute a versatile and reliable approach to evaluate dispersion and aid in the development of surgical devices.
