Abstract
An adapter is provided for use with a biopsy device that includes a cutting element having an outer cannula hub removably mounted to a handpiece. The cutting element includes an outer cannula connected to the outer cannula hub and an inner cannula disposed within the outer cannula and attached to the handpiece. The outer cannula hub allows removal of the handpiece and inner cannula from the outer cannula. The adapter includes a base, a cradle moveably mounted to the base and configured to rotatably support the biopsy device therein, and an indexing guide moveable with the cradle having a receptacle within which the outer cannula hub is rotatably received. The cradle and indexing guide are configured to inhibit rotation and axial movement of the biopsy device relative to the cradle, and facilitates removal of the handpiece and inner cannula from the outer cannula, while maintaining registration with the biopsy site.
