The 4D bioprinter that recreates the fabric arrives in Brazil

Rokit’s Dr. Invivo 4D bioprinter, technology that will enable the printing and subsequent regeneration of organs, such as kidney, liver and heart grafts, which will reduce the need for organ donation and the rate of rejection and infection.

The first license granted by Anvisa to the equipment is for the treatment of more complex skin lesions and wounds, such as diabetic foot ulcers, burns, skin cancer, among others.

“This is cutting-edge and innovative technology that will help thousands of people. In this first step we will avoid many amputations, especially in patients with diabetic feet and difficult to heal wounds. It is initially available for the private network, but we hope it will soon be offered to SUS patients as well, as the treatment is very affordable and will bring big savings to the government, ”says Dr. Maurício Pozza, partner-owner of 1000Medic, the company in charge of bringing the technology to the country.

Also according to Pozza, the results are faster than traditional methods, with a total wound healing in 30 days, occurring in over 85% of patients treated with the technology.

Initially, the treatment kits for the production of the biological adhesive will be available in hospitals that have the bioprinter. Hospitals and clinics wishing to purchase the printer and kits can do so through 1000medic, the exclusive distributor of the equipment in Brazil.

Currently, 3 cases have been treated in Pato Branco, Paraná, for demonstration to the Thereza Mussi hospital team. The equipment is already available for commercial use throughout Brazil.

According to the distributor, soon the idea is to have distributors in the four regions of Brazil to serve selected cases.

How tissue bioprinting is performed

The first step is to remove all the necrotic tissue. Then, a photo of the wound is taken with the help of an iPad with 4D software, which measures all wound dimensions. Then the photo is sent to the bioprinter.

Then, a small liposuction is performed in the abdominal region of the patient, where the adipose tissue rich in stem cells is located. This fabric is microfiltered and then mixed with natural fibrin glue.

To produce the biological dressing, a reagent is introduced into the printer and creates the tissue base. Subsequently, the stem cell material is added to form the dressing. This biological dressing is ready in about seven minutes.

Once ready, it is placed over the wound, which remains closed for 30 days, which is time for healing to take place. The entire surgical process takes about 30 minutes.
