Rod shaped elongated body e.g. needle, supporting and controlled translational displacement device for percutaneous medical procedure, has movable and fixed chucks, and actuators grouped on support plate opposite to chuck carrying structure

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.
