Abstract
An ophthalmic endoprobe including a hand-piece and a cannula assembly having a longitudinal axis is provided. The cannula assembly including an inner tube concentric with an outer tube; wherein the hand-piece may further include a motor powered by a pneumatic energy source, the motor providing motion to a transmission shaft; and a transmission system to couple the shaft motion to the cannula assembly; wherein the transmission system provides a counter-rotating motion to the inner tube and the outer tube about the longitudinal axis of the cannula. A fluid console for use in endoscopic ophthalmic microsurgery including a pneumatics module to obtain a pneumatic force from an external source and provide an adjustable pneumatic force; a scanning module coupled to the pneumatics module; and an endoprobe coupled to the scanning module is also provided.
