    Abstract: A surgical instrument has a hollow tubular member, and a pressurization unit that has an outer valve portion, a pressurization device having a movable part configured to generate pressurized fluid when the movable part is moved, and an inner valve portion. The inner valve portion includes a first flow passage that is configured to fluidically connect a first port and a second port of the outer valve portion to each other when the inner valve portion is in a first position, and a second flow passage that is configured between the inner valve portion and the outer valve portion to fluidically connect the first port and a third port when the inner valve portion is in a second position. A sealing system fluidically isolates the second port and the third port from each other at any position of the inner valve portion. Pressurized fluid from the pressurization device causes the inner valve portion to move from the first position to the second position, thereby providing positive pressure to the hollow tubular member.

    Abstract translation: 外科器械具有中空的管状构件和具有外部阀部分的加压单元,具有可移动部件的加压装置,所述可移动部件被配置为当可移动部件移动时产生加压流体,以及内部阀部分。 内部阀部分包括第一流动通道,其构造成当内部阀部分处于第一位置时将外部阀部分的第一端口和第二端口彼此流体连接;以及第二流动通道, 内阀部分和外阀部分,当内阀部分处于第二位置时,流体地连接第一端口和第三端口。 密封系统在内阀部分的任何位置处将第二端口和第三端口彼此流体地隔离。 来自加压装置的加压流体使得内部阀部分从第一位置移动到第二位置,从而为中空管状构件提供正压力。
