摘要：
A prosthetic system (1) includes a prosthetic foot (4) with a foot member (6) defining a first and second end portions (8, 10). A pump mechanism (2) is coupled to the foot member (6). The pump mechanism (2) includes a housing (36) defining a cavity (50), and a membrane (42) situated in the cavity (50). The pump mechanism (2) is movable between an original configuration and an expanded configuration. A movable member (34) includes a first portion (68) coupled to the membrane (42) and a second portion (66) arranged to slidably engage the foot member (6). Relative movement between the first and second end portions (8, 10) moves the first portion (68) of the movable member (34) relative to the housing (36) and slides the second portion (66) along a length of the foot member (6) to shift the pump mechanism (2) between the original and expanded configurations.
