Claim:
A biopsy device comprising: (a) a probe assembly; and (b) a needle assembly extending distally from the probe assembly, wherein the needle assembly defines a longitudinal axis, the needle assembly comprising: (i) a needle portion having a distal end; and (ii) a blade assembly comprising: (1) a blade, wherein the blade comprises a first cutting edge and a second cutting edge, wherein the first cutting edge and the second cutting edge are converge to form a point; and (2) a multi-member coupling assembly having a proximal end, wherein the multi-member coupling assembly comprises a first coupling member and a second coupling member, wherein the multi-member coupling assembly is configured to couple to the blade on opposite sides of the blade lateral to the longitudinal axis such that a proximal portion of the blade is laterally interposed between the first and second coupling members, and wherein the proximal end of the multi-member coupling assembly is configured to couple to the distal end of the needle portion.
