Remotely adjustable tissue displacement device |
摘要 |
The invention relates to an apparatus for displacing tissue within the body, wherein the apparatus includes two or more attachment members selectively displaceable with respect to each other via a driving member. The driving member preferably is rotatable and is caused to rotate by a magnetic actuator that can be activated by a magnetic field from outside the body. |

1. A bone displacement apparatus comprising: a first bone attachment member; a second bone attachment member; and a displacement mechanism configured for subcutaneous implantation in a position accessible by a magnetic field transmitted through skin, the displacement mechanism comprising a rod operatively coupled to the first bone attachment member, a drive member operatively attached to the rod, the drive member having first screw threads, a tubular member operatively coupled to the second bone attachment member, an inner surface of the tubular member having second screw threads to engage the first screw threads, and a magnet rotatable back and forth in opposite directions, wherein when an external rotating magnetic force is applied to a magnet, the rod moves in a displacement direction in accordance with a rotational interaction of the first screw threads and second screw threads, wherein the drive member is driving by a ring having a tab that contacts a tooth of the drive member. |
