我们开发了一种用于柔性神经内窥镜的执行器驱动的脉冲水射流装置（ADPJ），以实现有效的组织解剖和脉管系统保存。尽管灵活性对于微创来说是一个强大的优势，但延性曲率对解剖轮廓的影响仍然未知。本研究的目的是阐明ADPJ连接管曲率变化对解剖安全性和有效性的影响。使用三个不同内径（1.0、0.75、0.5 毫米）的 ADPJ 连接管来解剖大脑模型。它们以 3 个角度弯曲：0°、60° 和 120°。分别使用平均深度和变异系数（CV）评估解剖轮廓的有效性和安全性。连接管内径越大，解剖深度越深。无论每个管的弯曲程度如何，解剖深度都不会改变。无论内径和曲率如何，CV 都没有显着差异。柔性神经内窥镜的延性曲率不影响 ADPJ 解剖剖面的有效性和安全性。在众多仪器中，管状装置，包括 ADPJ 等抽吸和注射装置，可以安全有效地使用，而不受灵活性相关的限制。
We developed an actuator-driven pulsed water jet device (ADPJ) for flexible neuroendoscopy to achieve effective tissue dissection with vasculature preservation. Although flexibility is a strong advantage for minimally invasiveness, the effect of the ductile curvature on the dissection profiles remains unknown. The purpose of this study was to clarify the impact of the curvature change of the ADPJ connecting tube on the dissection safety and efficacy. Three ADPJ connecting tubes with different inner diameters (1.0, 0.75, 0.5 mm) were used to dissect the brain phantom. They were bent at 3 angles: 0°, 60°, and 120°. The dissection profiles were evaluated using the mean depth and coefficient of variation (CV) for efficacy and safety, respectively.The larger inner diameter connecting tube dissected more deeply. The dissection depth was not changed regardless of the curvature degree in each tube. There was no significant difference in CVs regardless of inner diameter and curvature. The ductile curvature of the flexible neuroendoscope did not affect the efficacy and safety of the ADPJ dissection profile. Among the numerous instruments, tube-formed devices, including suction and injecting devices such as ADPJ, can be used safely and effectively without flexibility-related limitations.
