A new method and design for a percutaneous biopsy system that cuts only the tissue lesion specimen and that does not penetrate through or beyond the targeted tissue into intact tissue. The proposed mechanism operates only in the targeted lesion space and leaves healthy or unsuspicious tissue intact. The proposed biopsy mechanism will cut the specimen in front of the tip of the guiding needle. The device may be image guided by ultrasound, any x-ray based modality or magnetic resonance (MRI).
