Abstract

一种止血阀、导管鞘以及介入器械(9)的密封方法，止血阀包括壳体(1,100)以及安装于壳体(1,100)内且呈管状结构的密封膜(2,130)，管状结构的内腔(21)作为器械通道(11,131)且贯通壳体(1,100)，壳体(1,100)内设有处在密封膜(2,130)外围用于填充流体的驱动室(12,150)，止血阀还包括可与流体相联动的储能机构(3)，储能机构(3)在密封膜(2,130)状态变化时相应的储能或释能，且在释能时驱使密封膜(2,130)密封器械通道(11,131)。通过储能机构(3)的设计，将密封膜(2,130)形变能量储存起来，从而实现不同器械通过时的兼容性好，密封效果好；通过密封膜(2,130)自身参数的设置、储能结构的参数设置以及两者之间的匹配，实现器械拉拔操作感好，操作力变化小的优点，并且为其他功能提供结构基础。
