摘要：
An ophthalmic surgical device 10 includes a housing 12 having a distal end 14 and a proximal end 16. A cannula 18 is attached to the housing distal end 14 and has a distal tip 20 with at least one port 22 in communication with a lumen 19 extending through the cannula 18 and in communication with an aspiration path 24 in the housing 12. A vibration source 26 is held within the housing 12 for vibrating the distal tip 20 for assisting in vitreous and other tissue removal. An aspiration source 152 connected to the aspiration path 24 for applying a negative pressure to the lumen 19 and the at least one port 22 for removing fluids and the vitreous and other tissue from the eye. The vibration source 26 and the aspiration source 152 together create a periodic bidirectional flow of tissue through the port 22 without creating cavitation externally of the distal tip 20.
