TIP AND HANDPIECE FOR OCULAR SURGERY, OCULAR SURGERY SYSTEM USING THEREOF

摘要

The present invention relates to an intraocular surgery tip, an intraocular surgery handpiece, and an intraocular surgery system using the same. The intraocular surgery tip irrigates a flushing medium to an intraocular affected area at a particular level of pressure, and is used for an intraocular surgery, including a cataract surgery, which aspirates an affected area tissue needed to be removed through an aspirating path. To this end, the intraocular surgery tip comprises: a flushing pipe having one end connected to a flushing medium accommodating unit for accommodating a flushing medium, having the other end equipped with a spraying unit for spraying the flushing medium, and providing a particular level of positive pressure into an eyeball through the flushing medium supplied from the flushing medium accommodating unit; and an aspirating pipe formed to surround the flushing pipe, having one end connected to a vacuum pump, having the other end equipped with an aspirating hole, and aspirating a biological tissue in an eyeball through the aspirating hole to the outside of the eyeball. The flushing pipe and the aspirating pipe are inserted in an eyeball, and a biological tissue separated from a vesica by a particular level of positive pressure of the flushing medium provided from the flushing pipe is aspirated by the aspirating pipe. Accordingly, a conventional inconvenient method used for removing fine cortex residues is excluded, and a surgery time may be reduced.
