Surgical aspirator probe with adaptive tip

摘要

A surgical tip having a soft adaptive distal end that conforms to the irregular cross sectional contours of lens fragments, this construction allowing better occlusion of the tip distal end by adapting to the irregular shapes of the lens fragments thus improving the efficiency of the lensectomy probe by enhancing vacuum build up, reducing the total irrigant volume required to complete the lensectomy process and protects the lens capsule from accidental rupture said soft tip being usable with vibratory based, laser-based and water-jet based lensectomy handpieces as well as lens aspiration cannula.

主权项

1. A lensectomy probe comprising: a) a controllable vacuum source; b) a probe distal end conforming an aspiration opening, said aspiration opening in fluid communication with aspiration means; c) the probe distal end with a rim including an elastic deformable portion circularly disposed around said aspiration opening in a way that said elastic deformable portion is adaptive to conform by pressure or vacuum to the irregular cross sections of lens tissue fragments providing faster and better occlusion of said tip aspiration opening by said lens tissue fragments.
