Minimum standard for amputee
Minimum standard for amputee
The minimum standard for amputees is actually light, labor-saving, safe and comfortable.
Lightweight refers to: the joint itself weight is low, the alloy knee joint we now import is to choose light and durable, and prosthetic accessories, acceptance cavity every link should be in line with the principle of reducing the prosthetic weight to choose.
Labor saving refers to: we want to choose air pressure or hydraulic power knee joint.
Safety refers to: the knee joint with geometric lock, or load-lock knee, manually unlocked knee joint, etc., this kind of knee joint can let patients alternately downstairs, down the slope, bus, steps will not fall. You think about walking without worry, do not worry about falling down, can let go of the courage to walk, so that gait is more natural.
Comfortable refers to the adaptation of the cavity and residual limbs. The technology of accepting the cavity is very important, do a good job of patients not stuck, gait naturally, go further.

The attention for installing the thigh prosthesis
The attention for installing the thigh prosthesis
Patients with thigh amputations generally choose prosthetic limbs according to the length of the residual limbs, and hydraulic joints are suitable for patients with knee amputation. With medium and long residual limbs can choose a number of joints, air pressure or hydraulic four-link air pressure knee joint or multi-axis geometric lock knee joint can be selected. The short stump must be locked with a multi-axis air pressure or hydraulic knee joint.
Today, take you to understand the prosthetic knee joint. All the knee joints are mechanical joints, increasing the air pressure, hydraulic, intelligent control unit on the mechanical joint is the air pressure knee joint, hydraulic knee joint and intelligent knee joint. Some knee joints also have a multi-axis geometric lock or a single bearing heavy self-locking device.
According to the length of the residual limb, the shape of the amputation level is different, whether there is skin grafting needs to look at the residual limb first, and then the suitable prosthetic assembly scheme is recommended within the scope of the patient's purchasing power. The walking gait is also related to the patient's age, weight, living environment and the level of the technician when the prosthetic limb was first assembled.

Weight affects prosthetic comfort
Weight affects prosthetic comfort
Some patients and editors reported that the feet are a bit hard, and the experience is not as good as before. Here, the editor will explain in detail the relationship between weight and prostheses. Every lower limb prosthesis has a weight-bearing range. If the weight is higher than the weight of the prosthesis, it is easy to cause damage to the prosthesis, and the weight is too much below the weight-bearing limit. Some phenomena such as hard feet will occur.
The prosthetic master’s suggestion is that the weight of the fitted prosthesis exceeds the limit of the prosthesis by about 20 kg, because the weight of the user of the prosthesis must not be higher than the weight limit of the prosthesis, then the weight of the patient must be below the limit of the prosthesis, too much, too little. It's not so good. It is best for prosthetic patients to take a scientific and reasonable degree.
For the prostheitc foot plate, weight is not the main factor determining the comfort of the prosthesis. Because each calf prosthesis has a different design and different forces, the people who use it are also different. For example, some comfortable calf prosthetic feet, as long as the patient's weight is within the maximum weight-bearing range of the foot, regardless of the patient's weight distance and the maximum weight-bearing amount, it will not affect the comfort, because it is designed for the patient to use the calf prosthesis very comfortable .
However, some energy-storing feet are different. It is designed to compress the feet through suitable gravity for the patient to walk, and the feet will then generate reaction forces to make the patient walk more easily. The greater the weight, the greater the reaction force, but the greater the weight, the easier it is to damage the prosthesis, so at this time, the patient's weight must be carefully considered to fit the standard of the prosthesis.

Is it better to have a silicone (gel) liner for the prosthesis socket, or an inner liner, or even an adsorption type? What are the characteristics?
Is it better to have a silicone (gel) liner for the prosthesis socket, or an inner liner, or even an adsorption type? What are the characteristics?
1. The silicone sleeve experience is the best, but the price is the most expensive.
2. The gel sleeve is secondly softer than the silicone sleeve (suitable for obvious bony processes), and the stability is lower. The price is cheaper than the silicone sleeve, but the service life is shorter, so it is generally not recommended. But if the legs are not shrunk for the first time, you can install a cheaper one. It will save money if you change the cavity after a few months of shrinking and change the silicone sleeve.
3. The traditional inner liner is usually made of polyethylene foam and is relatively hard. If it is not done well, it is easy to wear and tear. If the technology is good, it can also be done well. However, if the technology is generally recommended, silicone sleeves are generally recommended. Negative pressure is not conducive to the health of residual limbs.
4. Adsorption is suitable for short stumps of thighs. If the traditional inner liner is easy to fall off, and the silicone sleeve is too expensive, then this method is adopted. This kind of socks cannot be added. , The skin is definitely not very comfortable in direct contact with the receiving cavity, and the use of negative pressure suspension is harmful to the stump and can only be adapted.
