Dr. Bernstein demonstrates how he places the tensioner on the patient in a robotic hair transplant procedure. The tensioner is a plastic picture frame-like device that adds tension to the patient’s scalp allowing for improved harvesting. It also has little dots, called fiducials, on its outer border which the robot “reads” for proper orientation. The robot scans the edges of the tensioner, reads the dots, and uses them to orient the robotic arm and punch tool.
The ARTAS Robotic System uses a small, window-like device called a tensioner to help hold the scalp in place and to help guide the 3D optical technology that locates and extracts follicular units.
