MR compatible neurosurgical positioning apparatus
First Claim
1. An apparatus for supporting a surgical instrument in the operative environment of an imaging device, the apparatus comprising:
- means for supporting the surgical instrument in a desired position along a desired trajectory, the means for supporting including a first member having a first aperture extending therethrough adapted to receive the surgical instrument and a second member having a second aperture extending therethrough, the second aperture adapted to receive the surgical instrument, the relative positions of the first and second members being selectively adjustable to vary the relative position of the first and second apertures thereby securing the surgical instrument; and
means for securing the means for supporting.

Abstract
An apparatus (1) for supporting a surgical instrument in the operative environment of an imaging device comprises components all made of a material compatible for use in the operative environment of the imaging device. The components of the apparatus (1), made of such a material, include a member (32) that has a spherical surface and includes a bore (50) extending through the member along its diameter. A grip (26) has a grip surface (40) defining an aperture that is adapted to receive the member for rotatable movement within the aperture. The grip (26) extends around the member (32) in a circumferential path and has a gap (42) therein. A fastener (30) is operatively connected to the grip (26). The fastener (30) is adjustable to change the size of the gap (42) and adjust the compressive force applied to the received member (32) in the grip.
