protéziseket

A protézis (plural: protézisek) is an artificial device designed to replace a missing body part. These devices are crucial for restoring function, appearance, and overall quality of life for individuals who have lost limbs, organs, or other body structures due to injury, disease, or congenital conditions. The development and application of prosthetics represent a significant field within biomedical engineering and medicine.

Prosthetic limbs are perhaps the most commonly recognized type of prosthesis. These can range from simple cosmetic replacements to highly sophisticated devices that mimic the function of natural limbs, often incorporating advanced electronics and sensors. For example, modern prosthetic legs can allow users to walk, run, and even navigate uneven terrain, while prosthetic arms can enable gripping and manipulation of objects. The materials used in prosthetic limbs are carefully selected for durability, lightness, and biocompatibility, with common options including plastics, carbon fiber, and specialized metals.

Beyond limbs, prosthetics are also used to replace internal organs or parts of organs. Dental prosthetics, such as dentures and implants, are a common example, restoring the ability to eat and speak. Cochlear implants can restore hearing, and artificial heart valves can improve cardiovascular function. The design and fitting of a prosthesis are highly personalized, requiring close collaboration between the patient, prosthetist, and medical team to ensure optimal fit, comfort, and functionality. Rehabilitation and training are often essential components of prosthetic use, helping individuals adapt to their new device and regain independence.
