Surgical method and apparatus
View Patent ↗A method and apparatus for directing relatively gentle pulses of heated surgical fluid against the capsular bag to assist in the removal of lens epithelial cells and cortical material adhered to the capsular bag.
1. A lavage tip for handpiece, comprising:
a) an inner tube having a distal end coaxially mounted within an outer sleeve so as to form a fluid path between the inner tube and the outer sleeve;
b) a plurality of interior tubes contained within the inner tube; and
c) a hood at the distal end of the inner tube, the hood reducing the velocity of fluid exiting the interior tubes.
2. A method of polishing a capsular bag, comprising the steps of:
a) holding a first handpiece tip near a capsular bag, the first handpiece tip having
i) an inner tube having a distal end coaxially mounted within an outer sleeve so as to form a fluid path between the inner tube and the outer sleeve;
ii) a plurality of interior tubes contained within the inner tube; and
iii) a hood at the distal end of the inner tube, the hood reducing the velocity of fluid exiting the interior tubes;
b) holding a second handpiece tip near the capsular bag, the second handpiece tip capable of aspirating tissue removed from the capsular bag; and
c) directing fluid exiting the first handpiece tip against the capsular bag.
