Abstract[English]
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.[French]
Certains modes de réalisation concernent un vitréotome comprenant un boîtier, un actionneur disposé à l'intérieur du boîtier, un dispositif de coupe accouplé à l'actionneur et s'étendant à partir du boîtier et une turbine à air disposée à l'intérieur du boîtier. La turbine à air comprend un rotor et une pluralité de pales de turbine accouplées au rotor. Le vitréotome comprend un corps de pompe s'accouplant au rotor. Pendant la rotation de la turbine à air, de l'air est sélectivement acheminé vers et depuis l'actionneur en fonction d'une position de rotation du rotor par rapport au corps de soupape, ce qui permet animer le dispositif de coupe d'un mouvement de va-et-vient.
