An endoscopic biopsy assembly includes an endoscope that has a working channel and a suction device. A biopsy unit is provided and the biopsy unit is insertable into the working channel in the endoscope for obtaining a tissue biopsy. The biopsy unit is in fluid communication with the suction device such that the suction device urges air inwardly through the biopsy device and into a tissue trap. The biopsy unit is urgeable into a cutting position for obtaining the tissue biopsy. The suction device suctionally urges the tissue biopsy out of the biopsy unit and into the tissue trap thereby facilitating the tissue biopsy to be acquired without removing the biopsy unit from the endoscope. Moreover, the biopsy unit is repeatedly urgeable into the cutting position for obtaining and thusly acquiring multiple tissue biopsies without removing the biopsy unit from the endoscope.
