![]() Depending on how many hairs are grafted, it usually takes approximately 3 to 4 hours of treatment, with breaks. It is considered quite mainstream and is a fairly simple and acceptable procedure. “People are more comfortable now with this type of hair restoration treatment. Using a rechargeable battery system has made the new tool portable and transferable from clinic to clinic and country to country without considering different power supplies. Using a direct drive solution increased the device’s service life and offered a reduction in weight and vibration compared to geared motor solutions. The motor is from maxon’s configurable DCX direct drive range which facilitates the handheld design by offering high power density and torque in a small design. The innovative new drill is exact, reliable and extremely small, the nose is just 0.8mm. “We were going in the wrong direction with our motor choice and consulting Martin allowed us to adapt without wasting a lot of unnecessary time and resources in testing the wrong solutions.” “His advice was extremely valuable and saved us a lot of time on this project. “Martin directed us towards choosing a direct drive motor without gears because this would eliminate the issues around noise and vibration while increasing the product's service life,” explained Ypatidis. After initially deciding to go with a geared motor for their device, the team contacted Martin Leahy, maxon's Sales Engineer in Ireland, to discuss concerns about noise and vibration. He chose maxon's products for the final design because of their small size and relatively high torque compared to similar options available from other manufacturers. ![]() Ioannis Ypatidis, a programmer and roboticist, is the Project Manager who developed the new device. Having been involved in developing various medical devices and surgical tools over the years, the clinic’s experts were confident they could design a more streamlined and effective hand-held follicle extraction device that was light, robust, fast and had wireless capabilities. Most existing follicle extraction devices are heavy and bulky, so the clinic’s experts decided to call on their 20 years industry experience to design a new device for themselves.
