Abstract

A biopsy needle, a biopsy needle assembly and methods to perform biopsy are disclosed. The biopsy needle includes a primary needle section formed as a hollow tube; a converging section accurately converging from a wall of the hollow tube of a first end of the primary needle section to form a piercing tip; a secondary needle section; and a body. The converging section of the biopsy needle further includes an opening on a lateral wall having a third cutting edge. The body of the biopsy needle is coupled to a second end of the primary needle section and may be coupled to an actuator to control a linear and a rotational movement of the biopsy needle.
