Abstract
Certain embodiments provide a vitrectomy probe including a housing, an actuator disposed inside the housing, a cutter coupled to the actuator and extending from the housing and an air turbine disposed inside the housing. The air turbine includes a rotor and a plurality of turbine blades coupled to the rotor. The vitrectomy probe includes a valve body interfacing with the rotor. During rotation of the air turbine, air is selectively routed to and from the actuator according to a rotational position of the rotor in relation to the valve body, thereby reciprocating the cutter.
