Abstract
A surgical biopsy instrument for the extraction of at least one tissue sample from a body is disclosed having a piercing needle for penetrating the body. The piercing needle has a piercing tip and a tissue receiving port. A cutting member having a distal sampling segment is used with the piercing needle. The sampling segment has a cutting edge and a bore therein. The sampling segment is breakable from the cutting member. A tissue sample is acquired within the sampling segment of the cutting member after the tissue sample is taken at the tissue receiving port of the piercing needle. The sampling segment is removed from the piercing needle and the sampling segment containing the tissue sample is removed from the cutting member.
