Biopsy guide

Abstract

Abstract A surgeon can select an entry point and a target point in a preoperative image volume of the patient. The target point and entry point form a trajectory line (28) along with the surgeon wishes to perform a surgical procedure such as a biopsy and line up a surgical instrument. In the present invention, once a surgical platform (10/22) is moved along a guide arm or arc (12) close to a point on the trajectory line (28) the surgical platform (22) is locked to the guide arm (12). A pivot point position at the centre of a ball joint (26) in the middle of a metal plate is then arranged to be exactly at a point on the trajectory line (28). The metal plate is locked down and the ball joint (26) is rotated to ensure that the surgical sleeve (24) extends exactly along the trajectory line (28). This allows a decoupling between the position and orientation movements required to line the surgical sleeve (24) up with the trajectory line (28) to perform a surgical procedure. An interoperative localization device (ILD) is used to track the position of the surgical guide relative to the image space.
