AbstractAn automatic bone traction device includes a main body, a distractor (18), a flexible shaft (13) and connectors (9, 11). The main body consists of a high torque movement mechanism (2) which contains a step motor, a series of transmission gears, a PCB (3) and a button battery (6). The flexible shaft is used to connect the transmission gear assembly and the bone distractor (18) with the connectors (9,11). And then the generated driving torque is transmitted to the distractor (18) through the flexible shaft (13). The flexible shaft (13) allows the main body of the bone traction device to be mounted away from the bone distractor at a convenient location for the user.
