Single axis knee joint with manual lock VS Bearing lock knee joint

.Single axis knee joint with manual lock VS Bearing lock knee joint Some patients hope that the knee joint has very good safety, so you can choose a manually locked knee joint, which can be manually locked, and will automatically unlock at the early stage of walking. This is the most stable knee joint. Although this joint requires more power to use and looks stiff and clumsy, it can walk in a locked condition. The manually locked knee joint is very suitable for patients with weak control of the prosthesis and for active patients who often walk on uneven terrain.   Another option is the weight-bearing self-locking knee joint, which is also very stable and is usually used in the first prosthesis. When weight is applied to the joints, the joints will not bend until the effect of gravity is eliminated (raise the leg to prepare to walk). The system uses constant damping during the swing phase of the prosthesis, but uses gravity to keep it mechanically locked during the standing phase. For older or less active amputees, this knee joint is the most common choice.

pneumatic knee joint VS Hydraulic knee joint

.pneumatic knee joint VS Hydraulic knee joint Both air pressure and hydraulic pressure are known as the use of fluid mechanics to control joints, which provide variable resistance, allowing patients to walk comfortably at different speeds.   These devices consist of pistons in cylinders, including air or liquid. When the knee is bent, compressed air stores energy, which is then released when the knee joint is extended. Gait control is further enhanced by adding spring coils. Pneumatic joints can generally provide excellent swing control performance, but the efficiency is lower than that of hydraulics.   For active amputees, hydraulic joints can provide the closest function to a normal knee joint. The hydraulic system uses a liquid medium (usually silicone oil) instead of air to respond to various travel speeds. Although hydraulic knee joints provide a smoother gait, they are heavier and require more maintenance, and the assembly cost is very high.

The maintenance of lower limb prosthesis fitting sleeve

The maintenance of lower limb prosthesis fitting sleeve   The foam plastic decorative coat of the skeletal thigh prosthesis, it needs to bend frequently the knee joint part most easily aging fracture. When using lower limb prosthesis with decorative coat, we should pay attention to avoid the collision of hard and sharp objects, and carry out regular maintenance. If there is slight damage, you can use the same material to paste and repair, if there is fracture or large area damage, you need to find a professional to replace. Daily cleaning can use 75% alcohol or soapy water to wipe the outer side of the decorative coat, and dry naturally.

Basic function of upper limb orthosis

Basic function of upper limb orthosis   1） Fixed function Also known as static function, fixed of joints, fracture sites to promote healing of lesions or tissues. This kind of orthosis is used to fix limb function, limit abnormal movement of limbs, restore upper limb function, suitable for inflammation of upper limb joint and tendon sheath, traumatic injury, etc. 2） Adjuvant function   Also known as dynamic function, this kind of orthosis is used to prevent the occurrence of upper limb deformity and joint overstretch, to ensure the effect after operation and the normal development of bone during development.   3） Corrective function Also know as orthopaedic function to prevent and correct joint deformities. This type of orthosis is used to control the development of deformities by applying only a small force through the principle of three-point force correction to correct deformities of the fingers, wrists, elbows and shoulders without pain. 4） Also know as enhanced function, compensatory loss of muscle function. This type of orthosis uses elastic devices such as springs, rubber bands, plastic elastomers, or through pneumatic, electric or cable-controlled devices to strengthen finger movement and train muscle strength. Including the use of some auxiliary tools, self-help appliances to help paralyzed patients restore function. 5） protective funtion   Protect weak muscles. Protect the upper limb from injury or lesion, prevent overstretch or strain of joints and tendons, promote the healing of lesions, and also protect some surgical scar sites. From simple wood splint to complex suspension and traction equipment, all belong to this kind of norm distortion.   SHIJIAZHUANG AOSUO O&P

Main role of upper limb orthosis

Main role of upper limb orthosis   The advantages of an upper-limb orthosis in treatment depend on clinical, and effective choice limits, aids, or creates movement. The correct use of these features can play a very important role in achieving the following goals, which are achieved through appropriate combinations of static, moving and dynamic orthosis components. 1） Prevention and correction of malformations 2） Protect the painful, inflammatory and healing tissues. 3） Increase the function, assist or compensate to stabilize structurally unstable joints. 4） Static orthosis are rigid structures that keep the body in an ideal position. 5） The orthosis of movement has joints that allow patients to produce motion from their own muscles or some external power sources. The design of joints and alignment determine the allowable motion plane and arc, while the brake can further limit the motion arc.   SHIJIAZHUANG AOSUO O&P
