Cataract Removal Tool

摘要

A cataract emulsifying tool having a hollow shaft delivering pulsed fluid is improved by having a bend in the hollow tube or an angularly adjustable socket receiving the hollow tube. This disposes the axes of the handle and the hollow shaft at angles to each other to facilitate working over a prominent superior orbital rim or right and left angles ergonomically benefiting a surgeon.

主权项

1. An improvement in an emulsification tool used to direct pulsed fluid against cataract material in an eye to surgically remove cataract material from the eye, the tool having a handle, a hollow shaft, and a tip that delivers the pulsed fluid, the improvement comprising:
an axis of the shaft is disposed at an angle away from an axis of the handle so that a separation of the axes increases with distance from the handle; the separation of the axes is oriented to the shaft to clear a superior orbital rim of an eye while allowing the tip to aim at the cataract material of the eye; the separation of the axes also being arranged to dispose the tip at an effective angle relative to the cataract material while holding the shaft clear of the superior orbital rim; and the angle between the axes being in a range of 2° to 45°, depending on the contour of the superior orbital rim.
