Abstract

A device for supporting and controlling the translational movement of an elongated body, the body extending along the longitudinal axis thereof in the form of a rod, such as a needle intended for a percutaneous medical procedure. The device is designed to be mounted to a support that can be controlled in terms of position and orientation, and includes: (i) a first member for gripping the body, whose movement can be controlled in the translation direction with a pre-determined maximum stroke; and (ii) a second fixed member which can guide the elongated body when the body is moved by the first mobile gripping member and which can maintain the body in position when the body is not engaged with the first member.
