Using a 3D printer, you can create prosthetic devices from the patient’s tissues


Swiss scientists have learned to create artificial limbs using the patient’s tissues. This allows to ensure a high level of survival of the implant prosthesis, while reducing the amount of surgical intervention.

To create a unique prosthesis requires a special 3D-printer, as well as the cartilaginous tissue of the patient, which after multiplying at the cellular level is mixed with the biopolymer and then the previously created model prints the prosthesis. The cartilage is collected using a biopsy from the knee area or fingers. After some time after implantation, the biopolymer decomposes without causing harm to the patient’s body, and the cartilage remains in the prosthesis. To demonstrate the new technology, scientists created a prosthetic nose.

It is expected that with the help of new technology 3D print surgeons will be able to perform prosthetics of the nose, ears, and also to restore articular cartilage. But when it is available to patients, it is still unknown. Now experts actively test it on laboratory mice.

Note that the technology of three-dimensional printing is already used in medicine. For example, a year ago in the Netherlands, a unique operation for transplanting a 22-year-old patient of the upper part of the skull, created on a 3D printer, was successfully performed . And earlier with his help surgeons from Great Britain returned the face to Stephen Powers.
