Rounded-end device, system, and method for preventing posterior capsular opacification

摘要

Disclosed herein is an apparatus selectively attachable to an ultrasonic device to disrupt target cells from underlying tissue for treatment of an ocular condition, including a shaft, a coupling portion at an end of the shaft, and a cell disrupting end extending from a distal portion of the shaft. The shaft has a longitudinal axis and a first diameter. The coupling portion includes a connector portion and a hub configured to selectively couple to the ultrasonic device and impart ultrasonic vibration to the shaft. The cell disrupting end is solid and has a second diameter and a smooth, continuous, curved shape.

1. An apparatus to disrupt target cells from underlying tissue for treatment of an ocular condition, comprising:
an ultrasonic device comprising:
a horn; andan aspiration tube extending through the horn; and a first selectively attachable component configured to block the aspiration tube of the ultrasonic device when attached to the ultrasonic device, the first selectively attachable component comprising:
a shaft having a longitudinal axis and a first diameter;a coupling portion at an end of the shaft including a connector portion and a hub configured to selectively couple to the ultrasonic device and impart ultrasonic vibration to the shaft; anda cell disrupting end extending from a distal portion of the shaft and having a second diameter, wherein the cell disrupting end is solid along the longitudinal axis and has a smooth, continuous, curved shape.
