Skin biopsy in one click

Today, there are two methods of skin biopsy: the thin section method, which involves the removal of a thin layer of skin, which then heals on its own, as well as the puncture skin biopsy, which is performed using a special tool that is placed perpendicular to the surface of the skin and advanced deep into, to capture the deeper layers of the skin and subcutaneous fat. To avoid discomfort during the procedure, the skin biopsy is performed under local anesthesia. However, both of these techniques may soon give way to a more modern and simple "click method" that will speed up the diagnosis of pathologies such as skin cancer.

New possibilities for diagnosing skin cancer

The Carlos III University of Madrid (Universidad Carlos III de Madrid), in collaboration with the Institute for Health Research at the Ramon Cajal Hospital, has developed a new skin biopsy technique. The new instrument allows skin biopsies to be performed with fewer instruments and reduces the procedure time from 30 minutes to 5. In addition, the procedure does not require local anesthesia or specialized personnel.

"This invention is a compact and easy-to-use ergonomic instrument and allows the use of only one device to obtain a skin sample. The new device is able to make an incision and automatically remove a tissue sample, while adhering to all sanitary and hygienic standards established by the Institute for Research in the field of "Ramon Cajal", – says Jesús Meneses, one of the developers of MAQLAB Research Group.

Early detection of skin cancer

The invention will help speed up the diagnosis of pathologies such as skin cancer, and will also optimize the work of doctors who go through a large number of patients. This is of paramount importance in areas such as dermatology. The device will allow the patient to leave the doctor's office with a diagnosis, which means that treatment can be started earlier if necessary.

"The device prototype is ready for demonstration and is currently under patent protection," says Christina Castejon, researcher at MAQLAB Research Group. The next step is to find ways to bring it into service on a massive scale.
