Usage |
The cable-controlled upper limb prosthesis is suitable for patients with wrist amputation, forearm amputation, elbow joint amputation, and upper arm amputation. After certain use training, it can assist patients in lifting, holding, eatingwith a spoon, writing with a pen, and supporting Take simple daily activities such as cycling. Normally, it is in thefunctional position where the thumb, index finger, and middle finger are combined. When picking up objects, thehand is opened by pulling the traction cable, and the hand is closed by the torsion of the spring. This kind of prosthetic hand has a simple structure and saves effort to hold things. |
Classification of upper limb prostheses:
Classified according to the function of the prosthesis: 1 decorative upper limb prosthesis, 2 lock-controlled upper limb prosthesis, 3 myoelectrically controlled upper limb prosthesis, 4 hybrid upper limb prosthesis.
Decorative upper limb prosthesis:
It is a passive prosthesis.
Emphasis on lifelike appearance, comfortable wearing and light weight
, Easy to operate. Passive with some upper limbs
Basic functions, such as passive hand opening and closing, passive flexion and extension
Elbow etc.
In principle, it is suitable for all amputation planes, multi-purpose
For finger amputation, high upper limb amputation and certain difficult-to-fix
A patient with a rope grip.
Cable controlled upper limb prosthesis:
Also known as 'active grip arm
It is an upper limb prosthesis with its own power source. its function live
movement is through the residual limb movement and the shoulder girdle control system
Completed. In order to make the various functions work together
, and require extensive training from the patient.
Cable-controlled upper limb prosthetics are suitable for use in addition to hand amputation
All amputation planes except for high amputation
patients, especially shoulder amputees, using the prosthesis is very
difficulty.
The prosthetic hand assembled can be divided into two types: free hand opening and free hand closing.
kind.
Open hands freely: thumb, index finger, and middle finger in normal state
Pinch the function bit of the object. finger stretching by traction
Open, rely on the torsion of the spring to close the fingers, the structure is simple
Single, saves effort by holding objects, but amputee cannot control force at will
size, soft, weak items can be deformed, pinched
broken.
Close your hands at will: in a more natural open position under normal conditions
The finger is closed by the traction cable to form a pinching functional position
. The grip strength when fetching objects can be controlled by the patient through the traction cable
When holding objects, the residual limbs should continue to use force.
It can also be installed for daily life or professional work
Tool hand designed for movement.
Myoelectric control of upper limb prosthetics: a source of external force
type prosthetics, the particularity of this system is for the upper limb
Prosthetics have important effects, and their fitting effects are not
only depends on the structure of the prosthesis, but more importantly
To what extent a reliable 'human-machine connection' can be achieved,
That is, whether the amputee can make the artificial limb complete with the body
Combined.
How Myoelectric Prosthetics Work
Myoelectric signals from the muscles of the stump will be used to control the
The functional activity of the prosthetic limb, this EMG signal in the muscle
Produced during contraction and can be measured on the skin surface with
several volts. It is led out by electrodes and controlled after amplification
The movement of the motor. Through special mechanical reduction gear
Converts the rotational energy of the motor into gripping function and rotation
wrist movement etc.
Hybrid upper limb prosthetics: cable-controlled, motorized, muscular
Electrical and other control methods are integrated and applied to prosthetics,
Internal and external power sources work together.
It is mostly used for the amputation plane above the elbow joint.
2. The significance of assembling upper limb prostheses:
●Play a non-negligible role in the psychological rehabilitation of patients
Play the role of human body balance
@Children wearing prosthetics as soon as possible is good for balance and can prevent
Scoliosis caused by imbalance; good for children
Children adapt to prosthetics and can learn how to use them as soon as possible
With prosthetics, it is especially important when fitting myoelectric hands.
