Abstract:
An electro-mechanical traction device is provided which includes a motor driven linear actuator connected to a guided carriage. A second carriage is mounted in tandem with the first on a common guide. The two carriages are connected by a spring. A patient engaging device is connected to the second carriage. The linear actuator and carriage guide are mounted to a common surface. When power is provided to the linear actuator motor, it moves the first carriage. The motion is transmitted through the spring to the second carriage and patient engaging device to provide traction to the patient. Reversing the motor relieves the traction force.
