摘要:
A pneumatic valve (300, 710) directs pressurized air to and air exhaust (730) from a surgical implement (104), such as a dual actuation vitreous probe (750). The pneumatic valve (300, 710) includes an axialiy symmetric valve body (102, 302) configured to rotate from a first position, in which the pneumatic valve (300, 710) places a first port of the surgical implement (104) in fluid communication with the pressurized air and a second port of the surgical implement (104) in fluid communication with the air exhaust (730), to a second position, in which the pneumatic valve (300, 710) places the first port in fluid communication with the air exhaust (730) and the second port in fluid communication with the pressurized air, and back to the first position, in one rotational direction (320). As such, the axialiy symmetric valve body (302, 304) continuously rotates in one rotational direction (320) to alternate the pressurized air and the air exhaust (730) between the two ports (322) of the surgical implement (104) to drive the dual actuation operation (400).
