    • An irrigation and aspiration apparatus for cataract surgery or the like, which is particularly suitable for aspiration and removal of the cortex lentis during the surgical operation. As for the structure, the irrigation and aspiration apparatus of the present application includes a selector coupling to which ends of a plurality of aspiration tubes are connected, while the other ends of the aspiration tubes are respectively connected to handpieces which can perform aspiration, so that one of the handpieces for aspirating irrigating fluid and the like from a diseased eye of a patient can be chosen by switching the selector coupling. With this structure, aspiration and removal of the residual cortex after removal of the lens nucleus in the surgery of the crystalline lens can be accomplished easily and reliably, thereby relieving the doctor and the patient from the stress and load of the surgical operation.
    • 一种用于白内障手术等的灌洗和抽吸装置,其特别适用于在外科手术期间抽吸和去除皮质松果体。 关于该结构,本申请的冲洗和抽吸装置包括选择器联接器,多个抽吸管的端部连接到多个抽吸管的端部,而吸引管的另一端分别连接到可执行抽吸的手柄,使得 可以通过切换选择器联接器来选择用于从患者的眼睛吸入冲洗液等的手柄之一。 利用这种结构,可以容易且可靠地实现在晶状体手术中去除晶状体核后的残留皮质的抽吸和去除,从而缓解医生和患者的外科手术的压力和负荷。
