Q: I understand that in robotic hair transplant, a robot performs the extraction part of the FUE procedure. What’s the outlook on the robot doing more of the hair transplant procedure? — B.B., Greenwich, CT
A: Currently, the ARTAS® Robotic System is a technology for extracting grafts. This is the most difficult part of a follicular unit extraction procedure, but it is only one part.
There are two other major parts to the FUE procedure: one part is the creation of recipient sites (in our practice, we create the recipient sites first, so that once we harvest the grafts, we can immediately place them into the scalp), and the other part is graft placement.
Recipient site creation involves more than merely making holes in the recipient area.
It involves making decisions on hairline design, graft distribution, hair direction, recipient site size and depth. When done manually, the surgeon first designs the new hairline so that the hair transplant will look as natural as possible, particularly as the person ages. Next, the surgeon will demarcate the extent of the area to be transplanted and decide on the graft distribution (i.e., how much hair will be placed in each part of the scalp) and then prepare a “recipient site” on the part of the scalp that has lost hair. The surgeon will then manually create incisions in the recipient site into which the follicular units will be placed.
On February 8, 2014, Dr. Bernstein unveiled “recipient site” creation capabilities of the hair transplant robot. These new capabilities allow the doctor to import a hairline design and other markings that have been made on the patient’s scalp directly into the robot. The robot then maps the design onto a precise 3-D model of the patient’s head. The physician can then program the proper distribution, direction and depth of the future recipient sites and the robot then creates the sites according to the physician’s specifications.
Graft placement, the last step, is perhaps the most challenging to automate. Engineers are currently working to design and build the capacity to automate the placement of extracted follicular units into recipient site incisions. Done manually, it requires significant hand-eye coordination and a very slow learning curve. For the hair transplant robot, it will be a significant challenge with development taking several years or more.
