The recipient site incisioning is a crucial stage which directly affects the hair transplant result. The process requires attention on the following aspects simultaneously:

-Decision for the right blade type and dimension
-Linear motion
-Penetration force
-Angle, direction, tilt
-Density and natural distribution
-Avoiding intersecting
-Bleeding control
-Time management

Force, Stroke


The harmony between the penetration force and stroke enables the required tissue separation with equal quality and uniform depth allowing more comfortable placement of the grafts. The adjustability of the penetration force brings the advantage to adapt the incisions on different skin types. Fatigue, curved hand, imperfect anatomical movement, or distraction are factors that may cause irregular depths with manual incisions. Especially after the first thousand incisions, the depth may start to be disordered. The Robopen makes the cuts at the desired depth every single time. It is hard to control manually the stroke and how much force is to be applied during each incision. If the stroke is longer than necessary it may create a larger wound on the surface and also damage the subcutaneous revascularization which nourishes the hair follicles.

For instance, with a blade length of 4 mm, the target depth of the incision is 4 mm, but when more force and stroke is applied than necessary, the incision depth can reach 5 to 7 mm. This is very undesired. The clearest damage of this uncontrolled situation is necrosis. Even if necrosis does not occur, wastage of grafts, weak hair growth, and deformation of the skin are possible in this area and around.

Angle &

Linear Motion

More regular incisions: With manual incisions there is changes of linear axis due to the curved anatomical movement of the hand, due to the irregular full linear movement which affects the size of the incision. The ideal linear motions are deprived from the fallible movements of the wrist, elbow or shoulders and fatigue. The perfectly linear cuts can be made and maintained effortlessly. Incision intersection under the skin, which causes tissue and vascular damage are prevented.

The Robopen makes the cuts at the desired depth each single time. An aesthetic hair transplant result can only be achieved if the incisions are made in the right angles. The Angle can be controlled through the Angle Indicators on the tip of the device. The protractor at the lower part of the device helps the surgeon by showing the angles that the surgeon can use as a reference during the surgery on each position.

Comfort &


Recipient site incisions demand a lot of attention and time. A certain position has to be held for a considerable amount of time during manual incisions. Due to thousands of repetitive motions and the special attention required for each one, the surgeons who perform manual incisions, often experience back and muscle pain. The semi-robotic Robopen ensures less muscle pain due to the ergonomic design of the device and the shorter process. Fatigue and surgical time are reduced, and the hand/arm position will be more comfortable. While the palm-friendly design, the right weight, and surface make the incision process more comfortable, allowing you to create aesthetic hair transplant results adequately. You can plan the frequency and pattern, then drag the Robopen and the desired cuts are made. Enjoy the process! The process has been made more comfortable for the physician and patient due to the shorter process and better hand and arm positions.

The incision distribution is very important. To provide a natural-looking hair transplant result the distance between incisions often need to be less than 0.9 mm. With the Robopen, the cuts are made at the ideal depth, spacing, and alignment. The regularly parallel linear axis prevents the intersection on the dermis of neighboring incisions.

All features of the Robopen can be controlled by the LCD screen. The menu provides settings that can be adjusted and configured by the user. The batteries can be quickly changed during the surgery, which makes the process cordless. The soft button technique enables the smooth launching or cessation and minimizes fatigue of the fingers after a long surgery. The surgery time is also reduced due to its speed options. Incisions are counted by the sensitive sensors automatically. Distraction and speed are not hindrances anymore to know the exact number of incisions.

Incision Distribution &


With the stable linear axis motion each incision does not intersect neighboring incisions, So the follicles placed in each incision will be surrounded by the maximum amount of undisturbed tissue to promote revascularization-capillary growth to provide a blood supply to each transplanted follicle. Otherwise lower success rates can occur.

Doctors will be able to create more aesthetic hairlines thanks to the linear motion made by the device. More time can be saved for the aesthetic aspects of the surgery.
