Devices and methods are provided for removing fluid from a trocar or from surgical instruments passed therethrough, and for preventing such fluid from accumulating. For example, an exemplary method for removing fluid from a trocar can include positioning a trocar to extend into a body cavity and vibrating the trocar to prevent fluid in the trocar from being deposited on surgical instruments passed therethrough. In one embodiment, the trocar can be selectively vibrated by activating a foot pedal or remote control, or according to an output of a sensor. |
