PHACOFRAGMENTATION AND PHACOASPIRATION TIP
First Claim
1. Phacofragmentation and phacoaspiration tip for cataract surgery, regardless the cataract hardness, prepared for insertion of its distal end into any of the corneal incisions made for fragmentation and aspiration of an area—
- whether or not opacified—
of the lens. This phaco tip (1;
1′
) has been conceived as a cannular body, hollow by virtue of an axial orifice extended throughout the length of the tip, endowed with a proximal portion (1a;
1′
a) designed for connection with any type of handle. Its main characteristic is that the body of the phaco tip presents, from the head portion to the distal end (2;
2′
) an intermediate section (1b) of cannular body with a length (“
L”
) that spreads through most of the total length of the tip. After that intermediate portion (1b), the tip presents a distal end portion (1c;
1′
c) that in turn presents a strong external conicity as it advances towards the free end, and a length (“
L”
;
“
L′
1) a lot shorter than the length of the intermediate portion (1b;
1b′
), which determines a reduction of the thickness that when reaching the mentioned free end (2;
2′
) forms a slimmed edge, sharp but not cutting in itself to end in a blunt point.

Abstract
Description of a phacofragmentation and phacoaspiration tip used in cataract surgery prepared for insertion of its distal end into any of the corneal incisions made for the fragmentation and aspiration of the lens. The tip is made up by an internally hollow cannular body that comprises a proximal portion for connection to any type of handle. The main characteristic is that this phaco tip presents a portion from the head portion up to the distal end and a distal end portion that in turn presents a pronounced external conical shape as it progresses towards the free end which length is considerably shorter than the intermediate portion, determining a gradual or staggered reduction in the thickness which, upon reaching the mentioned free end, forms a slimmed edge, polished although not cutting in itself, that ends in a blunt or rounded shape which is defined through an “r” radio.
