Abstract: An aspiration device to be used with an irrigation-aspiration handpiece may comprise a curved body having a radius of curvature based on a human equatorial lens diameter, an interface adapted to attach the curved body to a first end of an aspiration lumen in the irrigation-aspiration handpiece, and multiple aspiration ports formed in the curved body. The multiple aspiration ports may be adapted to draw material into the aspiration lumen when a suction source is used to apply vacuum pressure at a second of the aspiration lumen while the aspiration lumen is attached to the aspiration device. The multiple aspiration ports may be arranged to distribute the vacuum pressure over an aggregate surface area of the multiple aspiration ports while the suction source applies the vacuum pressure.

Abstract: A surgical tool assembly is disclosed. The surgical tool assembly includes a forceps instrument including a proximal handle portion with an actuator, and a distal forceps portion including jaws. The actuator selectively moves the jaws. The surgical tool assembly includes an infusion assembly including a tube configured to be connected to a fluid source at a primary tube end and connected to a fitting at a paracentesis tube end. The fitting defines a passage configured to receive the distal forceps portion of the forceps instrument. An infusion sleeve extends away from the fitting. The infusion sleeve is arranged concentric around an outer surface of the distal forceps portion to define a fluid pathway. The jaws extend beyond a terminal end of the infusion sleeve such that the jaws are arranged outside of the infusion sleeve.
