Apparatus for positioning a medical instrument
First Claim
1. An apparatus for positioning a medical instrument relative to a patient, said apparatus comprising:
- a drive assembly for moving the medical instrument along a first axis that extends in a direction substantially parallel to the length of the instrument;
a rotable adapter for connecting the drive assembly to a positioning device, said adaptor comprising an axle for being received by the drive assembly and a pair of cooperating hubs, a first of said hubs extending from said axle and a second of said hubs being secured to said first hub by a holding member;
a positioning system comprising;
a substantially C-shaped arm having a first section comprised of said adapter;
a second section containinga first motor system for rotating said adapter and medical instrument about a first point positioned outside the body of the patient and a second axis that extends substantially perpendicular to said first axis; and
a third section operatively connected toa second motor system for rotating said adapter, said medical instrument and said first motor system about a third axis that extends substantially perpendicular to said second axis; and
a remote control unit for selectively operating at least one of said drive assembly motor, said first motor system and said second motor system.

Abstract
The present device provides an apparatus for securely positioning a medical instrument relative to a patient. The apparatus comprises a drive assembly for moving the medical instrument along a first axis that is substantially parallel to the length of the instrument; an adapter comprising an elongated member and a pair of cooperating hubs for connecting the drive assembly to a positioning system. The cooperating hubs serving to allow separation of sterile from non sterile components. The positioning system comprises two motors each for moving the instrument about a different axis than the drive assembly. The apparatus moving the instrument about a point which is external to the patient. The device further comprises a sterile bag which encloses the positioning system, the bag having at least one opening for receiving an axel from a sterile adapter assembly, thereby rendering the entire apparatus sterile.
