A cartridge includes an electrical connection assembly, a first port, a second port, a pumping mechanism, a valve, and a fluid flow sensor. The electrical connection assembly is configured to electrically couple to an electrosurgical unit. The first port is configured to fluidly couple to a fluid source. The second port is configured to fluidly and electrically couple to a surgical instrument. The pumping mechanism is disposed between the first and second ports and is configured to draw fluid from the fluid source and pump the fluid to the surgical instrument. The valve is disposed between the first and second ports and is configured to selectively obstruct the flow of the fluid therethrough. The fluid flow sensor is disposed between the first and second ports and is configured to sense fluid flow therethrough. The fluid flow sensor is configured to electrically communicate with the electrosurgical unit.
