Description

Description: TECHNICAL FIELD The present invention relates to a hair transplanter, and relates to a hair transplanter used to transplant a single piece of raw hair to a necessary part of the body.

(Conventional technology) When hair or body hair is lost due to illness or injury due to an accident, raw hair such as hair is transplanted to the area. A hole is made for this, and several downy hairs with supporting tissue cut off from the head are planted together in that hole. Then, the work of inserting several pieces of downy hair into the hole is performed by pinching it with tweezers or the like.

(Problems to be Solved by the Invention) In the above-mentioned conventional hair transplantation, since the hole to be bored in the site to be hair-transplanted is large, the hole remains as a scar even if the downy hair is fixed and grown after the hair transplantation. , The appearance is not good, and it is understood that the hair is planted at a glance.

Also, because the holes for hair transplantation are large one by one, bleeding is severe when the holes are made close to each other, and scars remain as described above, so the holes are generally opened at intervals. Therefore, there is a problem that the hair transplantation becomes coarse, and even after the growth, it becomes transparent and unnatural, and the survival rate is poor.

The present invention has been made in view of the above-mentioned problems of the conventional techniques. The purpose of the present invention is to adjust the direction and amount (coarse / dense) of hair transplantation, which enables natural hair transplantation and scarring. It is to provide a hair transplanter capable of performing hair transplant that does not remain.

(Means for Solving the Problems) In order to achieve the above object, the hair transplanter of the present invention is
A flocking needle is attached to the tip of the hollow body body, and a supporting tissue fixing core shaft projecting and retracting from the tip of the flocking needle is housed in the body body and is configured so that it can be operated to project from the outside of the body body. There is.

The flocking needle attached to the body body has a sharp tip,
In addition, a slit having a predetermined length is carved rearward from the tip. Further, an outer skin guide that moves up and down in synchronization with the supporting tissue fixing core shaft may be provided on the outer side of the body body.

The epidermis guide is connected to the core shaft for fixing the supporting tissue in the body body, and penetrates and projects from the tip of the body body, or protrudes through the slit of the flocking needle on the outer periphery of the tip of the core shaft for fixing the tissue support. It is good to do.

Further, when the above-mentioned epidermis guide is a rod rod supported in parallel with the supporting tissue fixing core axis, the tip portion contacting the epidermis may be in a shape in which the rod rod is cut, or a hair is transplanted at the tip of the rod rod. It is also possible to attach a frame so as to surround the needle.

(Operation) According to the above means, when the pushing operation portion of the supporting tissue fixing core shaft provided at the upper end of the body main body is pushed, the core shaft slides in the flocking needle to a predetermined length from the tip, Be projected. Therefore, the supporting tissue attached to the virgin hair is inserted and set in the tip portion of the flocking needle, and the virgin hair is projected outward from the slit formed in the flocking needle. In that state, hold the hair transplanter in your hand, insert it into the skin of the hair transplant part, and then pull up the body body while pushing the pushing operation part to support the upper end of the supporting tissue. Implants the supporting tissue in the hole formed by the flocking needle, and the flocking needle is detached from the skin.

Also, in the case where the hair transplant device is equipped with the epidermal guide,
When the flocking needle is inserted into the skin, the epidermal guide contacts the epidermis to regulate the insertion amount of the flocking needle, and the epidermal guide moves up and down in synchronization with the supporting tissue fixing core shaft, so that the pushing operation unit is pushed. Simultaneously, the raw hair with supporting tissue is transplanted into the hole, and at the same time, the epidermis guide projects and pushes up the main body of the body to detach the hair transplant needle from the skin.

(Effects of the Invention) Since the hair transplant device according to the present invention has the above-described configuration, one piece of raw hair with a supporting tissue can be reliably and reliably provided without damaging the supporting tissue (hair root portion). Can be easily flocked.

And, in the above-mentioned hair transplant, in a state where a hole is opened with a thin hair-transplanting needle, the downy hair and the supporting tissue set in the needle are pushed in by the supporting-tissue fixing core shaft for transplantation, so that there is almost no bleeding, Moreover, since the holes for flocking are very small, there is no fear of leaving scars as in the past.

Further, when the hair transplanter is provided with an epidermal guide that moves up and down in synchronization with the supporting tissue fixing core shaft, when the hair transplant needle is inserted into the skin, the epidermal guide contacts the skin and regulates the insertion amount of the needle. During the implantation of downy hair by pushing the core shaft for fixing the supporting tissue, the epidermis guide simultaneously moves down, which pushes the body body upward, and the flocking needle is detached from the skin.

Therefore, even a first person can easily plant hair with a uniform insertion depth.
