DEVICE FOR SUPPORTING AN ELONGATED BODY AND FOR THE CONTROLLED TRANSLATIONAL MOVEMENT OF SAME

摘要

The device has a fixed chuck (6) to guide an elongated body when the body is displaced by a body gripping chuck (5), and to support the body in a position when it is not held by the chuck (5). The chuck (5) is displaced alternately to the proximal and distant positions of the chuck (6). Actuators (24``, 25``) are grouped on a support plate connected on a platform of a robotic device opposite to a support structure carrying the chucks. The elongated body gripping chuck (5) is displaced in a controlled manner in a translation direction (Z) with a preset maximum traverse. The chucks (5, 6) are aligned in the direction (Z). An independent claim is also included for a system for assisting a percutaneous medical procedure guided by medical imagery.
