摘要:
A phacoemulsification probe for use with eye surgery comprises a connector for interconnecting the probe with a phacoemulsification machine. A probe tip has a first end with a first central axis running therethrough connected with the connector and a second end with a second axis running therethrough. The second axis is at a predetermined angle to the first central axis. The probe tip further includes a body defining a channel therein for aspirating material from a surgical region within an eye through an opening in the second end along a first vector. The body includes a straight portion around the central axis connected to the first end and a curved portion connecting the straight portion to the second end. A fluid sleeve surrounds at least a portion of the probe tip and has a first end and a second end. The fluid sleeve has a first portion at the first end having a first diameter that prevents a fluid from flowing between the fluid sleeve and the body of the probe tip. The fluid sleeve further has a second portion having a second diameter that defines a channel between an inner surface of the fluid sleeve and an outer surface of the body of the probe tip for injecting a fluid into the surgical region within the eye. The fluid sleeve defines at least one opening for injecting the fluid from the channel into the surgical region of the eye along at least one second vector.
