摘要：
A biopsy device for obtaining tissue samples from human or animal tissue is optimized for the sampling of tissues that are resilient and difficult to cut using conventional approaches. The biopsy device includes a cutting cannula, an inner member including a toothed rack having a sharpened distal tip configured to be introduced into the body and a sample notch for receiving the at least one severed tissue sample, the inner member receivable in the cutting cannula, and a cutting mechanism configured for causing the cutting cannula to be longitudinally displaced in a distal direction from a first position at the proximal end of the sample notch exposing the sample notch, to a second position at the distal end of the sample notch, so as to sever said tissue sample from remaining body tissue at the harvesting site. The toothed rack may be a rotatable and may be rigid.
