摘要
根据流体能量损失、流速、流量与枪体结构的关系,选择合适的喷嘴形式,选择合理的射流部分参数,提出为提高水刀喷枪可靠性采用的枪体内加过滤网、可更换堵塞的射流管、可调节的握柄、可清除残留组织细胞的负压吸引外管的结构,从而使水刀喷枪达到可多次使用,且故障率低或快速排除故障的性能.
According to the relationship between the energy loss of the fluid,the flow velocity,and the flow with the gun body structure.Take the gun body plus filter method to solve the problem that when the water knife nozzle is small that easy jams.Adopt replaceable type jet tube solve appear jams when cannot promptly eliminate malfunction.Use adjustable grip handle solve the different length require in different surgery.Adopt casing tube wall approach to solving the negative pressure attract residual tissues and cells is not easy cleared,so that the water spray can be used repeatedly,and the failure rate is low or quick troubleshooting performance.
