DEVICE FOR EXPANDING OR CONTRACTING HUMAN OR ANIMAL TISSUES FOR IMPLANTING IMPLANTS

摘要

Said device has a threaded cylindrical shaft (1) having a thread (2) in its lower half disposed in the opposite direction of the thread (3) provided in its upper half thereby enabling the location of two end bodies (4 and 5). Once the implant is implanted, the end pieces can be separated or moved towards one another by actuating the cylindrical shaft. The shaft is actuated (1) by a recess (6) which enables the insertion of a tool for mechanically actuating the shaft.
