Abstract:
A biopsy needle for collecting a tissue specimen includes a handle including a handle body that defines a hollow interior that includes a hollow inner housing member and a cannula assembly including an inner cannula, an outer cannula and a snarecoil coil at a distal end that is attached to the outer cannula. The biopsy needle also includes a first biasing element that is coupled to the cannula assembly and is configured to apply a force thereto when stored energy of the first biasing element is released to cause forward projection of the cannula assembly. A first mechanism of the needle has a first component associated with a proximal end of the inner cannula that is received within the inner housing member and a second component associated with the inner housing to cause controlled rotation of the inner cannula relative to the outer cannula after the cannula assembly is projected a predetermined distance.
