  • Method for calibrating performance range of a pneumatically sealed trocar
    Patent number: 10695511
    Abstract: A method and assembly for calibrating the pneumatic performance range of a system for delivering pneumatic power to a trocar, which includes the steps of: supplying pneumatic power to a trocar to achieve a desired cavity pressure; measuring the pneumatic power and cavity pressure over a time period, as the system attempts to maintain the desired cavity pressure; calculating performance characteristics of the trocar based on the measured cavity pressure and pneumatic power values; and adjusting the pneumatic power supplied to the trocar based upon the performance characteristics of the trocar.
