Abstract
A vitreous disintegration device with multiple intake ports and a laser for vitreous disintegrating. The probe includes a needle to accommodate the ports for a more continuous and fluidic uptake of vitreous from an eye of a patient. Additionally, the use of a laser may be employed to disintegrate the vitreous in a manner that avoids blocking of ports and thus, further promoting the fluidic uptake. The laser may reach the ports at the channel at substantially the same time or in succussion. Further, the use of a laser for the disintegrating means that cutter vibrations may be reduced.
Claims15
A vitreous disintegration device comprising:
- a tubular implement with at least two ports for the uptake of vitreous humor into a channel defined by the implement;
- and
- at least one laser emitting device in a surgical console coupled to the implement for delivery of a laser through an optical fiber to the channel and adjacent the at least two ports for disintegrating vitreous humor during uptake.
A vitreous disintegration device comprising
- a tubular implement with at least two ports for the uptake of vitreous humor into a channel defined by the implement;
- and
- at least one laser emitting device inside the vitreous disintegration device for delivery of a laser through the channel and adjacent the at least two ports for disintegrating the vitreous humor during uptake.
A method of performing a vitrectomy, the method comprising:
- advancing an implement of a vitreous disintegration device into an eye of a patient;
- withdrawing vitreous through at least two ports of the implement and into a channel thereof;
- and
- disintegrating the vitreous with a laser in the channel.
