Surgical system priming with pressure calibration utilizing handpiece orientation

A phacoemulsification system comprising:

• (a) a handpiece comprising a piezoelectric element and a distal end comprising a needle and a sleeve, wherein the distal end is configured to be inserted into an eye and to be vibrated by the piezoelectric element to emulsify a lens of the eye;
• (b) an irrigation module configured to supply a flow of irrigation fluid into the eye, the irrigation module is configured to be coupled with an irrigation channel of the handpiece via an irrigation line so as to enable flow of irrigation fluid therethrough;
• (c) an aspiration module configured for aspirating eye fluid, the aspiration module is configured to be coupled with an aspiration channel of the handpiece via an aspiration line so as to enable flow of an eye fluid therethrough;
• (d) a priming cover configured to fit over the distal end of the handpiece during a priming process;
• (e) one or more external pressure sensors configured to be coupled with the priming cover;
• (f) one or more sensors coupled with at least one of the irrigation channel, the irrigation line, the aspiration channel, and the aspiration line, and configured to monitor at least one of an irrigation pressure in the irrigation channel, an irrigation pressure in the irrigation line, an aspiration pressure in the aspiration channel, and an aspiration pressure in the aspiration line;
• and
• (g) one or more processors configured for operating a priming process including:
• operating the irrigation module to fill the irrigation channel and the irrigation line with irrigation fluid so that the irrigation channel and the irrigation line are free from air and irrigation fluid fills the priming cover;
• wherein the handpiece further comprises at least one orientation detection unit;
• and
• wherein the one or more processors being further configured for obtaining calibration pressure data from the one or more external pressure sensors and orientation data from the at least one orientation detection unit for calibrating pressure output data of the one or more sensors coupled with the irrigation channel, irrigation line, the aspiration channel, or aspiration line based on the calibration pressure data and orientation of the handpiece.
