Device for supporting an elongated body and for the controlled translational movement of the same
First Claim
1. A device for holding and for controlled translational movement, in a longitudinal direction, comprising:
- a first gripping part (5) configured for gripping a needle (2), movable relative to a support (3) in a manner that is commanded and/or controlled in a translational direction (Z) with a predetermined maximum travel; and
a second part (6) that is stationary relative to the support (3) and able to guide the needle (2) when the needle (2) is moved by the first movable gripping part (5) and, if necessary, to keep said needle (2) in position when the latter is not engaged with said first movable gripping part (5),the first and second parts (5 and 6) being aligned in the translational direction (Z) and whereby the first gripping part (5) can be moved alternatively between a proximal position of the second part (6) and a distant position of the device (1),wherein the first gripping part (5) comprises movable jaws (7), whereby the needle (2) is locked and the first gripping part (5) is a mandrel through which the needle (2) passes, whereby said mandrel (5) can be moved in rotation with the needle (2) around the translational direction (Z), and the jaws (7) are mounted, with a capability of guided sliding, in a body (10) with a tubular passage (10″
) that is designed to receive the needle (2), and the mandrel (5) presents in an open state a maximum opening of the jaws (7) and an opening degree to ensure total relaxation of the needle without lateral pulsation, such that movement of said jaws (7) is generated by a rotational movement of a rotary maneuvering ring (9) that surrounds the body (10),the needle being a needle for a percutaneous medical procedure, andthe device is configured to be mounted on an adjustable support, a platform or an arm of a robotic device in a manner that is controlled in position and in orientation.

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.
