Choi hair Transplant Implanter Pen originated at the Kyungpook National University (KNU) in Korea. The implanted helps works to combine the act of making a wound site in recipient area and implantation of an extracted graft into one act. We use a high platelet count solution to preserve individual donor grafts. Grafts are then loaded into syringe-shaped instrument and implanted directly into scalp without need to create donor incisions first. Thus avoiding the unnecessary trauma to the scalp Choi Implanter is a pen-like device featuring a hollow needle attached to a tube and plunger apparatus. During a hair procedure with the Choi Implanter, the hair restoration physician and/or technicians loads harvested follicular units into the implanter pen The surgeon then inserts the needle at an appropriate angle in the scalp (making the incision site) and implants the graft by pressing down on the plunger. Normally, anywhere from 2-6 Choi implanters are used concurrently during a procedure and the device comes in a variety of needle sizes to fit single, double, and triple follicular unit grafts According to some hair restoration experts, there are distinct advantages to the Choi Implanter device. Adequate graft survival rates, Decreased bleeding during recipient site creation Surgical Grade Steel IMPLANTER PEN According to some hair restoration experts, there are distinct advantages to the Choi Implanter device.
