Myoelectric and bionic upper limb prostheses with external power source - control of muscle impulses
Main advantages of myoelectric prostheses
Myoelectric and bionic upper limb prostheses — are modern prostheses that are controlled by muscle impulses. Built-in sensors on the skin surface read signals from the muscles and transmit them to a terminal device — hand or wrist, allowing for precise manipulations.
-
Control using muscle impulses: sensors convert signals from muscles into movements of the prosthesis.
-
Multifunctionality: the ability to control from two to five fingers with separate settings for the most frequently performed actions (holding a cup, toothbrush, typing on a computer).
-
Different levels of amputation: prostheses are made for the forearm, wrist and hand.
-
For any age: suitable for both adults and children.
-
Power supply: integrated batteries or inductive batteries ensure autonomous operation of the prosthesis.
-
Quick learning: it is easier to adapt if the patient has had experience using a traction-controlled prosthesis and has a well-formed stump.
Design features
-
Stump receiving sleeve — fits snugly to the limb stump, ensuring high-quality operation of the electrodes.
-
Built-in electrodes — read muscle signals and convert them into prosthetic movements.
-
Terminal device — bionic hand or wrist that provides manipulation.
-
Rotary wrist and switches (if needed) — improve the accuracy of movements and comfort of use.
Features of use
-
The patient controls the prosthesis mainly with visual control, since there is no biofeedback yet.
-
In case of amputation at the shoulder level, signals from the biceps and triceps are transmitted to the elbow and hand.
-
Myoelectric prostheses require regular maintenance of the battery and mechanisms to ensure long-term operation.
Myoelectric prostheses allow you to perform a wide range of actions: hold dishes, write, use cutlery and work tools, type on a computer or perform everyday manipulations with high precision.
