Abstract
The invention relates to a biopsy device having the ability to adjust the size of the sample to be removed. The biopsy device includes biopsy needle assembly and cannula insertion guide co-axially aligned therewith such that longitudinal adjustment of the cannula insertion guide likewise adjusts the exposure of the stylet and cutting edge of the biopsy needle assembly thereby changing the size of the resulting sample. A longitudinal adjusting element is positioned between and connects the cannula insertion guide and housing of the device. The invention is particularly useful in biopsy procedures where improved control over sample size and cutting stroke are desirable.
