DISPOSABLE HANDHELD PHACOMORCELLATION DEVICE

摘要

Disposable handheld phacomorcellation devices and methods for removing lens fragments from an eye of a patient are disclosed. In one embodiment, the phacomorcellation device includes a stationary outer tubular cutting member and a rotatable inner cutting member positioned within the stationary outer tubular cutting member. The outer tubular cutting member and the rotatable inner cutting member each include at least one cutting port having at least one cutting edge. The at least one cutting edge of the outer tubular cutting member and the at least one cutting edge of the inner cutting member cooperate to form a bird beak cutting structure as the inner cutting member rotates with respect to the outer cutting member. The cutting port of the outer tubular cutting member can be substantially closed during rotation of the inner cutting member, thereby preventing lens fragments from floating toward a posterior region of the eye.
