1. An adjustable elastic antagonist muscle replacement mechanism, which detects the muscle activity the patient wants to perform, capable of being changed under the control of an electronic system, of an elastic system which provides the tension applied by muscle or muscle group which lost their function, the mechanism comprising:
an adjustable tension chamber, which is formed from a loose polymer mesh in its middle segment, wherein the loose polymer mesh comprises a shuttle structure, and wherein the outer surface of the loose polymer mesh is coated with biocompatible elastomer; wherein the adjustable tension chamber contains an electrorheological fluid in it;
a screw hole is placed on one end of the adjustable elastic antagonist muscle replacement mechanism and is configured for attaching the adjustable tension chamber to the bones;
a tendon suture is placed on the other end of the adjustable elastic antagonist muscle replacement mechanism and is configured for attaching the adjustable tension chamber to the tendons or soft tissues;
a sensor-stimulator unit is adapted to configure the tension that is applied by the adjustable tension chamber and is adapted to change viscosity of the electrorheological fluid in the adjustable tension chamber;
a sensor electrode for detecting the electric activity generated by the peripheral nerves of the patient;
an afferent cable for transferring detected electric activity to the sensor-stimulator unit; wherein the sensor-stimulator unit is capable of generating an electric current according to the detected electric activity;
an efferent cable for transferring the electric current to a stimulator electrode connected to the adjustable tension chamber;
wherein the adjustable tension chamber is capable of applying a variable tension between two anatomic localization.
