A method for operating a biopsy device to acquire at least one tissue sample from a body of a living being, including retracting a sample-receiving device through a hollow needle to a sample removal position, a tissue sample being simultaneously transported to the sample removal position by the sample-receiving device; operatively connecting a liquid supply unit to a cavity of the sample-receiving device when the sample-receiving device is at the sample removal position; and delivering a lateral flow of a flushing liquid from the liquid supply unit to the cavity of the sample-receiving device to facilitate a lateral tissue sample ejection from the cavity.
