Choi Pen Hair Transplant

Newest hair transplantation instruments for even better results. Follicular Unit Transplantation and Follicular Unit Extraction (FUE) are complex and delicate procedures designed to restore naturally growing hair to the balding scalp. Because of this, hair transplant surgeons are frequently looking for methods to help improve the technique and maximize results. One way hair restoration innovators continually improve the procedure is by inventing new harvesting and implantation tools. One controversial tool that’s been discussed on our hair loss community is the “Choi Implanter Pen”.

When Follicular Unit Extraction was first implemented as a hair transplantation method, graft extraction and implantation was done using simple manual tools. The process was then sped up with the introduction of a machine known as a micro motor, which was using during both the extraction and the re-plantation stages. This mechanic device allowed surgeons to transplant a larger number of grafts through improved extraction. However, the micro motor has a number of disadvantages when used for the implantation of donor grafts.

Working Principle of the Choi Implanter Pen

The Choi Implanter originated at the Kyungpook National University (KNU) in Korea. The idea behind the implanter device was simple: to combine the act of making an incision site in the recipient area and the implantation of an extracted graft into one act. The 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 Choi Implanter is a pen-like instrument with a hollow needle on one of its ends. Using forceps, the graft is placed gently into the hollow needle (at the end of the implanter) and handed back to the physician.

Technicians at the operating room load extracted hair grafts into the hollow needle end. The surgeon then uses the pen to implant the pre-loaded into the scalp. 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.

This process is then repeated for every single graft. Normally, anywhere from 2-7 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. During our typical transplant, our hair transplant surgeon and the team use about 6 pens interchangeably to optimise the implantation time and pace.


Major Improvements and Advantages 

The use of an implanter pen eliminates the need for channel incisions. Previously, the operating team would need to create tiny circular incisions on the scalp and plant grafts inside these channels. Surgeons can now “inject” grafts directly into the recipient zones. This decreases trauma and blood loss during the transplant.

  • Adequate graft survival rates.
  • Decreased bleeding during recipient site creation.
  • Reduced trauma during graft handling.
  • Decreased time of surgery (with an experienced Choi Implanter team) due to the combination of graft site creation/implantation.

As a result, using the Choi Implanter Pen, our surgeons can now achieve significantly higher graft survival rate following the transplant. Furthermore, decreased trauma means faster healing times for our patients. There is clear and onvious evidence of better aesthetic results, as grafts can be positioned with greater precision during implantation.
