摘要：

To develop the novvel device for neuroendoscopic hematoma removal, we describe the Ho:YAG laser-induced liquiud jet system for hematoma fragmentation and liquefaction. Two types of nozzle were used (nozzle 1: internal diameter: 200 gm, nozzle 2: internal diameter: 1000 gm, each length: 5mm) and the pressure profiles of LILJ ejected from those nozzles were measured. And also the effectiveness of present system was evaluated by calculating liquefaction rate (measured as the percentage of the weight loss of the treated artificial hematoma) in vitro experiments.
