Title:
DEVICE FOR INTRABODY EXTENSION WITH SCREWS WORKING IN TRACTION
Document Type and Number:
WIPO Patent Application WO2007144489
Kind Code:
A9
Abstract:
A device for intrabody extension with screws working in traction. A first elongate section (1) receives a second telescopic section (2). Each of these sections includes means (61), (62) for connection to the body at a first end (11), (21), and is linked to a pin (3) containing at least one threading at a second end (12) and (22). Rotation of the pin (3) controlled by means (4) causes relative movement of the two sections (1) and (2). Thus, the pin (3) is mounted between two ends (12) and (22) which move closer when the device is elongated, and the loaded pin length (7) decreases when the device is elongated and the loaded pin length (7) works only in traction. The device according to the invention is specifically designed for making screws for bone elongation and growth prostheses.
