尽管水射流技术被认为是一种可行的神经内镜切割方法，因为它能够进行选择性组织切割而不会造成热损伤，但与连续用水相关的问题以及随之而来的喷泉效应-组织的反射-可能使水射流在安全性和易于操作方面不适合内窥镜使用。因此，作者在应用脉冲钬：钇铝石榴石（Ho：YAG）激光诱导液体射流（LILJ）期间进行了用水量最小化的实验，同时确保了传统水射流切割器械的切割质量和可控性。我们开发了LILJ发生器，用作刚性神经内窥镜，识别其机械行为，并使用尸体兔心室壁评价其剥离能力。
Although water jet technology has been considered as a feasible neuroendoscopic dissection methodology because of its ability to perform selective tissue dissection without thermal damage, problems associated with continuous use of water and the ensuing fountain‐effect—with catapulting of the tissue—could make water jets unsuitable for endoscopic use, in terms of safety and ease of handling. Therefore, the authors experimented with minimization of water usage during the application of a pulsed holmium:yttrium‐aluminum‐garnet (Ho:YAG) laser‐induced liquid jet (LILJ), while assuring the dissection quality and the controllability of a conventional water jet dissection device. We have developed the LILJ generator for use as a rigid neuroendoscope, discerned its mechanical behavior, and evaluated its dissection ability using the cadaveric rabbit ventricular wall.
