Abstract: An aspiration system to control vacuum pressure in an ultrasonic surgical handpiece to result in improved control responsiveness during aspiration. The system comprises a console including a vacuum pump. The system includes a cassette comprising a joint that divides a vacuum path into at least two flow paths. A first joint port couples to a first flow path. A second flow path is coupled to a second joint port, a third flow path is coupled to a third joint port, and a fourth flow path is coupled to a port on a surgical waste receiver. A first sensor senses pressure in the fourth flow path and provides a waste receiver pressure signal. A second sensor senses pressure in the third flow path and provides a tip pressure signal. The controller controls a position of a first vent valve and a second vent valve based on the waste receiver pressure signal and the tip pressure signal, respectively.

Abstract: A console-based surgical system comprises a plurality of handheld surgical instruments, each instrument having a connector line and an instrument visual indicator coupled to the instrument and/or connector line. The system further comprises a footswitch having a connector line and a footswitch visual indicator coupled the footswitch and/or connector line. The system further comprises a console, which in turn comprises a plurality of instrument ports, with the connector lines of the handheld instruments being connected to the instrument ports. The console further comprises a footswitch port, with the connector line of the footswitch connected to the footswitch port. The console further comprises a controller configured to associate the footswitch port with one of the instrument ports such that the footswitch is operable to actuate a function of the handheld surgical instrument connected to the associated instrument port. The controller is further configured to activate the footswitch visual indicator and the instrument visual indicator of the associated instrument port to display outputs that correspond with one another.

Abstract: An aspiration system to control vacuum pressure in an ultrasonic surgical handpiece to result in improved control responsiveness during aspiration is described. The system comprises a console comprising a vacuum pump, a surgical waste receiver, a clean side flow path, the clean side flow path positioned between the vacuum pump and the surgical waste receiver, a dirty side flow path, a fluid backflow device in communication with the dirty side flow path, a clean side venting mechanism in communication with the clean side flow path, and a second venting mechanism in communication with the fluid backflow device, wherein the dirty side flow path is positioned between the ultrasonic surgical handpiece and the fluid backflow device.
