DEVICES AND METHODS FOR BIOPSY

摘要

The present subject matter relates to a biopsy needle assembly (102) for performing biopsy. In one implementation, the biopsy needle assembly (102) includes a biopsy needle (106) which further includes a primary needle section (202), formed as a hollow tube, where the primary needle section (202) comprises a first end and a second end; a converging section (204) arcuately converging from wall of the hollow tube of the first end of the primary needle section to form a piercing tip (108). The converging section (208) further includes an opening on lateral wall to form cutting edges to extract the tissue sample. The biopsy needle (106) also includes a body (208) coupled to the second end of the primary needle section (202), where wherein the body (208) may be adapted for coupling to an actuator to initiate a movement of biopsy needle (106).
