Description

Hole punch for hair follicle extraction

technical field

The invention relates to a puncher for removing hair follicles.

Background technique

Affected by external factors such as social pressure and environmental pollution, more and more people are troubled by hair loss or baldness. Although baldness is not a disease, it seriously affects people's appearance, and even causes them to have low self-confidence and dare not develop interpersonal relationships. Therefore, the problem of baldness cannot be ignored.

At present, surgical methods have been used clinically to improve the problem of baldness. This operation is commonly known as "hair transplant surgery", which refers to a cosmetic surgery process that moves hair follicles from a certain place on the scalp (donor) to a place where it is needed (recipient) . Surgery usually uses the hair follicle, which is the natural composition of the hair follicle, as the basis for movement, resulting in the most natural appearance after surgery. A hair follicle basically contains 1 to 4 hairs, its diameter is about 1mm, and its depth is about 4-6mm.

At present, the most popular hair follicle transplantation technique is the hair follicle transplantation method (FUE, Follicular Unit Extraction). In the FUE technique, a hollow cylindrical and sharp-edged perforating tool such as a needle tube is used to first cut or scratch the edge of the hair follicle, and then use the extraction tool to pull out the hair follicle. However, the punching action is performed artificially; during the operation, the rotating needle tube should be steadily pushed into the scalp until a cylindrical hole with an ideal depth (about 2-5mm) is punched; then other tools are used to grasp the upper part of the hair follicle Gently pull out the hair follicles.

There are several inherent problems with the use of needles to remove hair follicles. First, through the connection between the hand and the wrist, the hand will naturally draw an arc. This non-linear movement can easily cause the hair follicle to be completely or partially cut off during the perforation process, thereby destroying the integrity of the hair follicle, resulting in injury and death of the hair follicle .

Second, it is very difficult to maintain straight-line movement when the hair follicle and the scalp present an extremely acute angle, and there is a greater chance of crossing the hair follicle.

Third, the high excision rate makes it more time-consuming to obtain hair follicles.

Fourth, during one operation, the hand has been repeatedly performing the action of moving the punching instrument back and forth steadily up to thousands of times. In the long run, this repetitive action may cause occupational injury to the wrist.
