Guide block for biopsy or surgical devices

摘要

One embodiment having features of the invention is directed to a guide block for an MRI device which has a block body with a proximal face, a distal face, and four parallel passageways extending between the two faces. The first passageway is centrally disposed, the second passageway is disposed vertical or horizontal to the first, the third passageway is located diagonal to the first and has a longitudinal opening in fluid communication with the first passageway, and the fourth passageway is diagonal to the first and in an opposite side of the body from the third passageway. In an alternative embodiment the guide block has at least one passageway that is not parallel to the longitudinal axis.

主权项

1. A guide block and grid-like breast receiving pressure plate assembly for a tissue removing device, comprising:
a. a guide block having a proximal face with at least a first proximal opening, a distal face with at least a first distal opening, a body length between the proximal and distal faces with a central longitudinal axis extending within the guide block between the proximal and distal faces, a first passageway configured to extend within the guide block between the first proximal opening in the proximal face and the first distal opening in the distal face, the first passageway being oriented at an angle with respect to the central longitudinal axis that is not parallel to the central longitudinal axis; and b. a grid-like breast receiving pressure plate having a plurality of openings configured to slidably receive the guide block, each opening of the plurality of openings in the grid-like pressure plate having a central longitudinal axis concentric with the central longitudinal axis of the guide block when the guide block is slidably disposed in a predetermined one of the plurality of openings in the grid-like breast receiving pressure plate.
