US Patent 8398578 Capsule friendly tips for phacoemulsification and for irrigation/aspiration

A surgical tool whose shaft terminates into a tip having a smooth, rounded edge and that has pores on its top or side, but none one the underside of its base. There may be a flattened base indicative of the shape of a bubble, basket, funnel, circular disc, oblong shape, Maltese cross or mulberry. The pores may be directed backward. A spring spiral may be provided within the shaft to exert a spring bias. The globe may be in the form of a sleeve fitted over a conventional phacoemulsification tip and needs to be positioned to keep the phacoemulsification tip from contacting the sleeve during operation. Alternatively, the globe may be part of a tip itself.
