Adapter assembly for stereotactic biopsy
First Claim
1. A medical device, comprising:
- a base;
a cradle moveably mounted to the base; and
an indexing guide moveable with the cradle and including a receptacle within which a portion of a medical instrument is received, the indexing guide including at least one guide lock slidably attached to the indexing guide, the guide lock moveable axially through application of an axial force to the guide lock between a locked position, in which the guide lock engages a portion of the medical instrument received within the receptacle to substantially prevent rotation and axial movement of the portion of the medical instrument received in the receptacle relative to the indexing guide and the cradle, and an unlocked position, in which the guide lock is disengaged from the medical instrument received in the receptacle, wherein the medical instrument includes at least one notch and the guide lock is configured to be received in the notch to prevent movement of the medical instrument in a first axial direction and the indexing guide includes a lip adjacent the receptacle, the lip including a projection extending inward of the receptacle and engagable with the medical instrument to prevent movement of the medical instrument in a second axial direction.

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.
