How much does it cost to have a prosthesis for the whole arm?
Prosthetic limbs, also known as "prosthetic limbs", are artificial limbs for amputees to use to compensate for part of the function of the missing limb. There are upper limb prosthesis and lower limb prosthesis. Mostly made of aluminum, wood, leather, plastic and other materials, its joints using metal parts.
Prosthetics refers to artificial limbs, used to replace the limb dysfunction (whether temporary or permanent), or used to cover up the limb disability. The biggest difference with prosthetics (such as breast implants, prosthetic noses, wigs and so on) is that prosthetics are more functional and refer only to the upper and lower limbs.Classification
According to the part? Upper limb prostheses? The whole arm and shoulder prosthesis: refers to the amputation part of the shoulder blade part of the prosthesis used by people, more common in electrical burns patients, is considered to be a very serious disability. Upper elbow prosthesis (full arm prosthesis): refers to the amputation site up to the elbow and above the use of prostheses. The lower elbow prosthesis: a prosthesis used by people who amputate up to the elbow. (The one used by Captain Hook is a below-elbow prosthesis!) Finger prostheses: may be a single finger or multiple fingers. Lower limb prosthetics:? Above-knee prosthesis: Amputation to the thigh part of the use. Below-knee prosthesis: for amputation to the calf. Foot prosthesis: for amputation to the foot. Foot prosthesis: for amputation of the sole of the foot. By function? Functional prostheses without organs: like Captain Hook's hook, the function is very simple, and many upper limb prostheses utilize modular kits that allow for different prostheses to be fitted in different situations. Functional Prosthetics with Organs: Most lower limb prosthetics are fitted with knots and spring systems, or even electronic power feedback systems, while many upper limb prosthetics utilize wires and springs to achieve grasping and other actions. Aesthetic prosthetics:? Prosthetics are made purely for aesthetics, such as the prosthetic hand, and can be very helpful to amputees in building self-esteem. Many prosthetic fitters also work on the make-up (painting) of these prostheses.It's not a big deal to rely on power.
There are now electronic prostheses on the market that contain computers and small actuators that help mechanical joints make more subtle movements.The medical engineering community has also been working on a number of new technologies to improve the quality of life of people with disabilities.
Currently, the medical engineering community is also actively researching artificial nerves or artificial muscles, and perhaps one day amputees will be able to use these new technologies to restore full functionality to their limbs.Technology
Recently, after detailed research, British medical experts developed a prosthetic metal implanted directly into the patient's bone, the patient will not only feel comfortable, and the prosthetic limb will become stronger and more useful. According to Hong Kong Wen Wei Po reported that the University College London Biomedical Engineering Center and a medical device center, the joint efforts to develop a revolutionary new technology, called through the skin of the bone within the prosthetic limb technology (ITAP), the researchers of the antlers in the skin of the animal after a detailed study of the growth of the way to come up with skin tissue surrounded by the growth of metal ideas. The new technology actually connects the prosthesis directly to the human bone, and the titanium rods in the prosthesis reach into the skin, causing the skin tissue to grow slowly around the metal implant, and the two are tightly bonded together, and the researchers believe that the new technology can solve the problem of bacterial infections in the transplanted part of the body. The trial of the new technique began in February of last year, and included two people who lost their arms in the July 7 London bombing. The attending doctors hope that this technology will help more patients who were injured in the 7.7 bombing and need to replace their prosthetic limbs. They have been recruiting more suitable people for the trial and expect to have the 20th patient participate in the trial in December this year, and this new technology is believed to have a wider use in the coming years. Not only does this technology look better than previous prosthetic technology, but it will actually make prosthetics stronger, more useful, and more realistic. By connecting the artificial limb to human bone and bonding the metal implant in the prosthesis to the skin tissue, the patient feels more comfortable and natural than if the prosthesis were simply strapped to the residual limb, and pain and inflammation are greatly reduced. In addition, a patient who lost a finger was able to pick up a pen and write for the first time in 10 years after participating in a trial of the new technology. On the other hand, some medical experts plan to add electronic devices in the prosthetic limb, connecting the patient's nervous system, the use of bionics to enhance the biological function of the prosthetic limb, so that the patient can more effectively control the prosthetic limb on them. With about 250,000 people undergoing amputations in the United States and Europe each year***, the new technology is expected to help 30 percent of patients, especially young people with no other physical complications. Early clinical tests have shown that patients in the trials are quite happy with the new technology, so doctors hope to help more patients who survived the 7.7 London bombings but need prosthetics, as well as injured military personnel and others who have lost limbs. Some in the medical community believe that ITAP will play an important role in the next generation of bionic prosthetics, and believe that within five years, amputee patients will be able to control their prostheses as they wish with the help of ITAP.Choosing a prosthesis
A person with a limb should be guided by a technician in choosing a prosthesis. Usually, the technician has to provide 2-3 assembly combinations according to the specific situation of the limb disabled person, and explain in detail the characteristics of various options for the patient and his family to choose. After determining the prosthesis assembly program, superb production technology is also needed to ensure the implementation of the design program, especially the production of the receiving cavity, the quality of joints and connectors, and the alignment adjustment of the prosthesis and the body. All of them are highly technical processes. Therefore, it is recommended that friends with limb disabilities choose manufacturers with strong technical force, high reputation and good after-sales service to assemble the prosthesis. What are the main factors to consider when choosing a prosthesis? The following factors should be considered when choosing a prosthesis:? (1) economic situation: according to their own economic situation to decide what price should be installed prosthesis, and then choose among the appropriate products.? (2) the amount of movement: if you need to engage in manual labor, you need to choose a durable product with a long lifespan; if you like to exercise and often walk on uneven surfaces, you need to choose a universal ankle, etc. (3) the weight and the weight of the prosthesis, you need to consider the following factors:? (3) weight and height: each type of joint has its own population. There are applicable weight range, the weight of patients to choose the joints to be able to fit, otherwise the life of the prosthesis will be very short; and light weight patients if you choose to fit the joints of the large weight will feel very heavy, walking laborious, and will not have a good gait. (4) Age: If young people have a lot of exercise, they should choose a flexible prosthesis; if the elderly have less exercise, they should choose a safe prosthesis. (5) gender: women are not suitable for the choice of a larger volume of prostheses; and men generally choose a large volume of strong prostheses. The electromechanical upper arm prosthesis is divided into domestic and imported. And there is a big difference in price according to the mobility of the elbow joint.? Domestic upper limb prostheses are generally priced above 20,000;? Imported upper limb prostheses generally cost more than 40,000 dollars;? The German Ottobock upper arm electromechanical hand is generally priced at 80,000 or more.? The calf prosthesis is mainly composed of a receiving chamber, a connector, and a foot plate. The material of the receiving chamber is mainly resin; the material of the connecting part can be made of alloy steel, aluminum alloy, titanium alloy, etc.; the foot plate has ordinary foot plate, energy storage foot plate, sports foot plate. The calf prosthesis material has domestic and imported. The modern prosthesis currently has a silicone sleeve process (mainly for the residual limb end of the skin conditions are not very good, diabetes or tumor amputation of the patient to use)? So there is no definite answer to how much you need for a calf prosthesis. Calf prosthesis can be divided into ordinary type, standard type, comfortable type. The price of the ordinary type in two or three thousand, the most high-end in six or seven million. This is according to your own actual situation and affordability. Currently, there are many brands in the prosthetic industry, and there are also many assembly units. It is recommended to go to the regular unit assembly, and choose a suitable prosthesis for your own, you can compare prices to do. Precautions after the installation of amputation. Good residual limb is a prerequisite for the assembly of prosthetic limbs, not only before the operation to consider the amputation site and amputation method, the residual limb training after the operation is also very important. First, under the guidance of the medical staff, it is necessary to master the care of the residual limb, maintain the hygiene of the residual limb and the prevention of complications. Secondly,? To pay attention to maintain a good position, in the prosthetic professional and technical personnel under the guidance of the strengthening of muscle strength, strengthen the joint range of motion training, to prevent the residual limb joint contracture and deformity. And as early as possible with a temporary prosthesis, which can accelerate the residual limb atrophy and stereotypes, early activities can reduce complications, help to improve the general physical condition of the amputee and mental condition, for permanent prosthetic limb early access to a satisfactory gait to lay the foundation.=========================================
Unveiling the world's top intelligent prosthetic limbs
Gaining a new limb: the mechanical arm made of cutting-edge technology is driven by 20 micro-motors, which simulate the movements of a living limb with unprecedented precision, and the user controls it through nerve impulses The user controls it through nerve impulses. The arm is even equipped with sensors that record the sense of touch. See accompanying photo, left
Following the heart: After Amanda Kitts's residual limb was surgically rewired with nerves, the muscles can still produce movement that is recorded by an array of sensors. The next generation of prosthetics can listen to the transposed muscle signals and move closer and closer to the flesh-and-blood limbs they were born with. See accompanying photo right
