1. An aseptic processing device for atraumatically morcelizing tissue biopsy samples comprising:
a processing chamber for receiving said tissue biopsy samples;
an axial pin support in fixed position within said chamber;
a stationary cutting disk non-rotatably mounted on said axial pin;
a movable cutting blade rotatably mounted on said axial pin in compressive biased engagement with said cutting disk for atraumatically cutting said tissue biopsy sample therebetween in a slicing action, while maintaining tissue viability;
a retaining clip positioned on said axial pin for maintaining said cutting blade in said biased rotational engagement with said cutting disk; and
an impeller engaging said cutting blade and for rotating said cutting blade about said axial pin and for repeatedly recirculating said tissue biopsy samples between said cutting disk and said cutting blade.
