Abstract
Apparatuses, systems, and methods are described for selectively generating an aspiration flow within a surgical instrument. Particularly, the disclosure describes example vitrectomy probes operable to selectively generate an aspiration flow in relation to operation of the cutter of the vitrectomy probe. In some instances, one or more valves may be used to form a barrier or closure and create a piston effect in order to selectively generate an aspiration flow.
