ADJUSTABLE ELASTIC ANTAGONIST MUSCLE REPLACEMENT MECHANISM

摘要

The present invention is an anatomic system which uses the principle of applying higher elastic tonus than the rest tonus of the agonist muscles to provide the function of the antagonist muscles, and which is designed in a simplest way to provide the said purpose and which can be integrated to the body. The static mechanism of the invention is an elastic mechanism which applies a continuous stable tension in order to keep the joints open. The tension of the mechanism is calibrated by increasing or decreasing the amount of the liquid in a chamber which has flexible and elastic walls up to a certain via a port. In the dynamic mechanism of the invention, the tension applied by the elastic mechanism can be changed according to the motion the patient wants to perform.

1. An adjustable elastic antagonist muscle replacement mechanism for eliminating the deficiency of the antagonist muscles capable of implementing higher tension than the resting tonus of agonist muscles that is the tension which they apply when the muscles do not generate any function, comprising:
an adjustable tension chamber, which is fanned from a loose polymer mesh in its middle segment, shaped like shuttle and the walls of which is coated with biocompatible elastomer:and wherein
a screw hole is configured for attachment of the adjustable tension chamber to the bones; a tendon suture is configured for attachment of the adjustable tension chamber (5) to the tendons or soft tissues; an injection port provides liquid in a desired amount being filled or discharged in to the adjustable tension chamber via an injector and can be left at a pouch formed under the skin; a nozzle is reinforced with a hardened elastomer clamp in the least mobile proximal part of the chamber; a biocompatible elastomer tube provides the injection port connected to the nozzle (10); an adjustable tension chamber capable of applying linear tension between two anatomic localization.
