A surgical instrument support is provided having an articulated arm (28) with first structure (80) on a proximal end (22) of the arm. A lockable target ball (96) is rotatably mounted on a distal end (30) of the articulated arm, and the lockable ball has a hole therein for receiving and supporting a surgical instrument. A mount (36) has second structure (76, 78) that receives and secures the proximal end of the articulated arm. The first structure on the articulated arm cooperates with the second structure on the mount to automatically align the proximal end of the articulated arm with the mount in a repeatable relationship. The mount is adapted to be releasably attached to a fixed structure (22). Thus, after establishing a desired alignment of the lockable ball to a patient, the articulated arm can be removed from the fixed structure and then subsequently remounted therein without losing the desired alignment of the lockable ball with the patient.

L'invention concerne un support d'instrument chirurgical. Ce support comprend un bras (28) articulé comportant une première structure (80) sur son extrémité (22) proximale. Une boule (96) cible verrouillable est montée de manière rotative sur l'extrémité (30) distale du bras articulé. Cette boule verrouillable comporte un orifice destiné à recevoir et à supporter un instrument chirurgical. Le support comprend en outre un système (36) de fixation comprenant une seconde structure (76, 78) destinée à recevoir et à fixer l'extrémité proximale du bras articulé. La première structure montée sur le bras articulé coopère avec la seconde structure montée sur le système de fixation pour aligner automatiquement l'extrémité proximale du bras articulé avec le système de fixation selon une relation reproductible. Le système de fixation est conçu pour être monté de manière amovible sur une structure (22) fixe. Ainsi après avoir réalisé l'alignement souhaité de la boule verrouillable avec le patient, on peut détacher le bras articulé de la structure fixe puis le remonter sur cette dernière en conservant l'alignement désiré entre la boule verrouillable et le patient.
