System for collecting and preserving tissue cores

The present disclosure provides a tissue sample retaining and preservation system, comprising: a tissue removal device configured to sever tissue samples; a tissue collector operatively connected to the tissue removal device and configured to receive the tissue samples; a temperature control sleeve disposed at least partially about the tissue collector, and a base member defined by an inner wall member and an outer wall members that are spaced apart from one another to define a hollow channel extending around the perimeter of the base member, the inner wall member further defining a reservoir configured to receive a cooling medium, wherein the temperature control sleeve is disposed within the base member and the temperature control sleeve at least partially defines a tissue collection chamber that selectively receives the tissue collector therein, and wherein the temperature control sleeve is in communication with the reservoir, while the tissue collector chamber is not in communication with the reservoir.
