Swiss scientists have learned how to create prostheses using the tissues of the patient himself. This makes it possible to ensure a high level of implantable prosthesis survival, while at the same time reducing the volume of surgical intervention.
To create a unique prosthesis, a special 3D printer is required, as well as the patient's cartilage tissue, which, after multiplying at the cellular level, is mixed with a biopolymer and then the prosthesis is printed using a previously created model. Cartilage is harvested using a biopsy from the knee or fingers. Some time after implantation, the biopolymer decomposes without harming the patient's body, and cartilage remains in the prosthesis. Scientists have created a prosthetic nose to demonstrate the new technology.
It is expected that with the help of the new 3D printing technology, surgeons will be able to carry out prosthetics of the nose, ears, and also restore articular cartilage. But when it will be available to patients is still unknown. Now experts are actively testing it on laboratory mice.
Note that 3D printing technology is already used in medicine. For example, a year ago in the Netherlands, a unique operation was successfully performed to transplant a 22-year-old patient with the upper part of the skull, created on a 3D printer. Earlier, with his help, surgeons from the UK returned Steven Power's face.
