HIGH SPEED PNEUMATIC VALVE

摘要

A pneumatic valve directs pressurized air to and air exhaust from a surgical implement, such as a dual actuation vitreous probe. The pneumatic valve includes an axially symmetric valve body configured to rotate from a first position, in which the pneumatic valve places a first port of the surgical implement in fluid communication with the pressurized air and a second port of the surgical implement in fluid communication with the air exhaust, to a second position, in which the pneumatic valve places the first port in fluid communication with the air exhaust and the second port in fluid communication with the pressurized air, and back to the first position, in one rotational direction. As such, the axially symmetric valve body continuously rotates in one rotational direction to alternate the pressurized air and the air exhaust between the two ports of the surgical implement to drive the dual actuation operation.
