use the combination shown in fig3 b to accomplish the steps shown in fig6 9 in a single step the hollow tube 50 can be considered equivalent to the probe 40 shown in fig4 a before the vacuum is applied the solid rod 51 can be slid within the probe 40 and the phaco shield 30 can be slid over the probe 40 after triggering the rod 51 to spread the ends 52 the rod is rotated and the phaco shield 30 is slid into place the flaps 23 are guided over the nucleus the rod 51 is rotated and removed the vibrating mechanism is attached to the rod 50 probe 40 and the vacuum is applied through the space vacated by rod 51 the inserting device although the invented phaco shield has been described for use in the removal of cataracts from the eye it can be used in a variety of areas in the body where unwanted materials are found within and in proximity to delicate vulnerable body tissue and a minimal incision is desirable such areas include but should not be considered limited to 1 foreign objects within the vitreous humor of the eye to be removed without damaging the retina 2 fatty deposits or blood clots within arterial areas to be shattered without damaging the walls of the arteries 3 lumbar discs to be removed by emulsification the shield can be modified to prevent injury to nerves or laterally to the spinal cord thus in its broadest sense this invention relates to the use of a device having a substantially sharp leading edge that is manipulated by the surgeon to remove usually by shattering of an unwanted.
