A cyclic aperture flow regulator system has an adjustable fluid aperture in a fluid path connecting the aspiration port of a surgical probe with a vacuum source. The cross-sectional area of the fluid aperture can be modified by an actuator. The actuator is controlled to modify the cross-sectional area of the adjustable fluid aperture in cycles. During each cycle, the fluid aperture cross-sectional area is substantially reduced or closed. The cycles occur at a rate fast enough to produce a substantially steady flow, with minimum flow ripple and pressure ripple.

A post-occlusion chamber collapse canceling system for a surgical apparatus that detects the breaking of occlusions by tissue fragments in the distal end of the aspiration path and produces a response consisting in a transitory blockage of the distal end the aspiration path to terminate the chamber collapse and a transitory venting of the aspiration line to relieve the vacuum, in a way that post-occlusion chamber collapses are cancelled.

A post-occlusion chamber collapse canceling system for a surgical apparatus that detects the breaking of occlusions by tissue fragments in the distal end of the aspiration path and produces a response comprising a transitory blockage of the distal end the aspiration path to terminate the chamber collapse and a simultaneous transitory venting of the aspiration line to relieve the vacuum, in a way that post-occlusion chamber collapses are cancelled.

An IOL injector device allows for both powered and manual delivery of an IOL. The injector has a tubular housing. A plunger is longitudinally disposed within the housing and has first and second ends. The first end is disposed towards the front end of the housing. A drive system is coupled to the housing. The drive system causes longitudinal translation of the plunger along the primary axis of the housing. A normally engaged clutch system is coupled to the drive system. The normally engaged clutch system allows manual disengagement of the drive system. A knob coupled to the plunger allows for manual operation of the injector.

An improved computer based surgical video overlay system that allows relevant surgical data from a surgical apparatus to be combined as a graphic image with the video image of a surgical procedure in which the data from the surgical apparatus is sent wireless to the video overlay console. Elimination of the data cable between the surgical apparatus and the video overlay console is advantageous in an operating room environment. The same computer based surgical video overlay system runs computer program that occupies a user interface to allows definition of operation modes, input of relevant data, selection of data overlay graphic screen templates and various methods for customization. A time coded-data file is created and stored including all the relevant parameters of a surgical procedure. This file contains the same time-code included in the graphic image overlaid in the surgical video signal. An precise match can be performed between the recorded data on file and the surgical video recording. An audio pre-amplifier section is provided to include surgical apparatus meaningful sounds produced during surgery. The alternative embodiment considers the use of an embedded computer within the video overlay console making the system capable of standalone operation providing a user interface and data input/output capabilities.

A method to improve phacoemulsification efficiency by providing bursts of axial ultrasonic activity in synchronization with a fraction of a lower frequency axial oscillatory activity, the fraction corresponding to the portion of the low frequency signal that displaces toward the lens fragments and distally from the phacoemulsification hand-piece. Ultrasonic bursts synchronized with displacement of the phacoemulsification needle tip toward the lens tissue increases efficiency allowing the reduction of the required ultrasonic power minimizing heat generation and cavitation.

A surgical instrument controller and actuating system that allows precise hand operated control of a powered instrument based on the detection of variations on the gripping force by means of pressure sensors located on the instrument handle. The grip pressure signal is processed by an electronic actuator controller which in turn drives an actuator system. The actuator system produces an actuation force that is proportional to the gripping force change detected at the instrument handle. The actuation force is transmitted to the active members of the instrument allowing precision proportional activation of surgical instruments such as micro forceps and micro scissors. The system allows an operator to precisely regulate the action of a surgical instrument by variation of the griping force applied over the handle of the instrument.
