Abstract

A surgical system with a variable controller that allows the user to selectively vary the level of venting performance.

Claims

1. A surgical system, comprising:

a surgical handpiece having an aspiration function;

a control console;

an aspiration pump at least partially located in the control console, the aspiration pump providing vacuum to the surgical handpiece through an aspiration line;

an aspiration vent in the aspiration line between the handpiece and the pump;

a reservoir coupled to the aspiration vent; and

a user input device coupled to the control console, the user input device comprising a touchscreen and/or a keyboard for receiving user input, wherein the user input comprises a venting parameter for the aspiration pump or the aspiration vent, and wherein the system is configured to vary the venting parameter of the aspiration vent or the aspiration pump according to the received user input, wherein the venting parameter is directly related to performance of the aspiration pump or the aspiration vent during a venting event;

wherein the user input comprises a requested amount of aspiration fluid to displace and wherein varying the venting parameter of the aspiration vent comprises opening the vent until the requested amount of aspiration fluid has been displaced from the reservoir.
