Description

本発明は、患者の頭皮のうち、毛髪がない領域あるいは毛髪が少ない領域に対し、その患者の他の領域にある比較的生命力の強い毛髪の毛根およびその周部領域を含む皮膚をドナーとして採取して移植する際に使用され、毛髪付きの皮膚をドナーとして採取し、吸引する毛髪移植用具のためのニードルに関する。   The present invention collects, as a donor, a skin containing a hair root and a peripheral region of a relatively vigorous hair in the other region of the patient with respect to a region of the patient's scalp where there is no hair or hair is low. The present invention relates to a needle for a hair transplantation tool that is used for transplantation, and that collects and aspirates skin with hair as a donor.

近年、かつらや人工毛植毛法に代わる薄毛に対する処置として、自毛植毛法が注目されている。自毛植毛法とは後頭部や側頭部など患者の毛髪のうち、比較的生命力の強い毛髪の毛根およびその周部領域を含む皮膚をドナーとして採取し、該ドナーを同じ患者の頭皮のうち毛髪の少ない領域や毛髪のない領域に移植する施術法に係る。自毛植毛は、かつらや人工毛植毛と異なり、患者自身の毛髪を脱毛部に移植して再生するものであることから、移植先での毛髪の生着率が高く、いわゆる拒否反応がほとんど見られないという利点がある。   In recent years, the self-hair flocking method has attracted attention as a treatment for thinning hair that replaces wigs and artificial hair flocking methods. The self-implantation method is a method in which the hair of the patient's hair such as the occipital region and the temporal region of the patient's hair is collected as a donor, and the skin including the hair root and the peripheral region of the hair is relatively strong. The present invention relates to a treatment method for transplanting to a region with little hair or a region without hair. Self-implantation, unlike wigs and artificial flocking, regenerates the patient's own hair by transplanting it into the hair removal site. There is an advantage that it is not possible.

出願人は、こうした自毛植毛を行うための毛髪移植用具として、下記特許文献１に示す器具の開発を行った。

JP 2007-229330 A

この文献に示される毛髪移植用具は患者の頭皮のうち、毛髪がない領域あるいは毛髪が少ない領域に対し、その患者の他の領域にある比較的生命力の強い毛髪の毛根およびその周部領域を含む皮膚をドナーとして採取して移植する際に使用され、この中で図５に示す移植用具１は、ドナーとして採取する毛髪２を中心として、その周部の皮膚に穿刺され、その部分の皮膚を穿開して吸引し、採取するためのものである。   The hair transplantation device shown in this document includes a hair root of a relatively strong vital force in the other region of the patient and a peripheral region of the region of the patient's scalp where there is no hair or where there is little hair. 5 is used when transplanting the skin as a donor, and the transplanting device 1 shown in FIG. 5 is punctured around the skin around the hair 2 collected as a donor. It is for opening, sucking and collecting.

すなわち、この毛髪移植用具１は、先端の内部にドナーとして採取する毛髪２を中心として、その周部の穿刺され、先端に円筒形の切込口３を備える全体管状のニードル４を備える。ニードル４は図７に示すように全体長尺状からなる直管状のものとされ、移植用具１の内部に交換可能に取付可能とされる。 In other words, the hair transplantation device 1 includes an overall tubular needle 4 that is punctured around a hair 2 collected as a donor inside the tip and includes a cylindrical cutout 3 at the tip. As shown in FIG. 7, the needle 4 is a straight tube having an overall long shape, and can be attached to the inside of the transplantation device 1 in a replaceable manner.

移植用具１には、先端の内部に取り付けられるニードル４の切込口３が対応する皮膚領域に穿刺された状態において、該ニードル４を軸回り（図５、図６のＡ方向）に回転可能とし、ドナー領域の皮膚を切込口３により穿開可能とする回転駆動手段としてのモータ５が備えられる。さらに移植用具１には、モータ５によるニードル４の軸回りの回転により穿開されて、切込口３内に留置されるドナー領域の皮膚を、吸引エアにより切込口３からニードル４の内部にドナーとして吸引し、さらにニードル４から該ニードル４に管路６を介して接続されるチューブ７により、採取容器８（ドナー貯留部）へと矢印Ｃ方向に搬送するための吸引手段としてのポンプ（不図示）が備えられる。 The transplant tool 1 can be rotated about the axis (A direction in FIGS. 5 and 6) in a state in which the cutout 3 of the needle 4 attached to the inside of the distal end is punctured in the corresponding skin region. And a motor 5 serving as a rotational drive means for enabling the skin of the donor region to be opened by the incision 3. Further, the transplant tool 1 is opened by rotation of the needle 4 around the axis of the needle 4 by the motor 5, and the skin of the donor region placed in the cut opening 3 is sucked into the inside of the needle 4 from the cut opening 3 by suction air. As a donor, and a pump as a suction means for conveying in the direction of arrow C to the collection container 8 (donor reservoir) by a tube 7 connected from the needle 4 to the needle 4 via a conduit 6 (Not shown) is provided.

すなわち、移植用具１によるドナーの採取は、モータ５を作動させてニードル４を軸回りに矢印Ａ方向に回転させ、ニードル４の切込口３を数mm程度頭皮に対し法線方向（矢印Ｂ方向）に穿刺し、毛根を含むドナー９を切込口３内に保持させる。この状態で吸引手段としてのポンプの作動により、切込口３内の皮膚を矢印Ｃ方向に吸引し、ニードル４の内部に吸引する。 That is, donor collection by the transplantation device 1 is performed by operating the motor 5 to rotate the needle 4 around the axis in the direction of arrow A, and the incision 3 of the needle 4 is in the direction normal to the scalp (arrow B). The donor 9 including the hair root is held in the incision 3. In this state, the operation of the pump as the suction means causes the skin in the incision port 3 to be sucked in the direction of arrow C and sucked into the needle 4.

ニードル４内に吸引されたドナー９は、管路６を介してチューブ７へと搬送され、さらに採取容器８へと搬送されて貯留される。採取容器８内にある程度の量のドナー９が捕集された状態において図８に示す容器８を開け、容器８内のネット１０に捕集されたドナー９を採取して移植先の頭皮に移植するようにしていた。 The donor 9 sucked into the needle 4 is transported to the tube 7 through the conduit 6 and further transported to the collection container 8 and stored. In a state where a certain amount of donor 9 is collected in the collection container 8, the container 8 shown in FIG. 8 is opened, and the donor 9 collected in the net 10 in the container 8 is collected and transplanted to the scalp at the transplant destination. I was trying to do it.

ところで、移植用具１に交換可能に取り付けられるニードル４は、図６に示すように先端側からモータ５を貫挿する状態で矢印Ｃ方向に挿入して接続され、このためニードル４には図７に示すようにモーター５の軸（内挿軸）に取付けるための支持体１１Ａ、１１Ｂが外装されている。ニードル４は、図７に示すように直管状のものとされるため、先端７で毛髪２を含む皮膚に穿刺される状態において出血量が多くドナー９をニードル４内に吸引する際、血液がドナー９とともに吸引されてしまい、吸引された血液が内径φ１．０〜１．４mm程度の範囲で形成されるニードル４の内壁に付着し易くなる不具合が発生していた。こうした不具合が発生すると、吸引されたドナー９が血液の付着されたニードル４の内壁部分に付着し、さらに該部分に吸引されたドナー９が塊状に詰まる不具合が発生していた。こうしたドナー９が詰まる部分は、ニードル４の基端側に多く発生するものとされていた。   By the way, the needle 4 that is replaceably attached to the transplantation device 1 is inserted and connected in the direction of the arrow C in a state where the motor 5 is inserted from the distal end side as shown in FIG. As shown in FIG. 2, support bodies 11A and 11B for mounting on the shaft (insertion shaft) of the motor 5 are externally provided. Since the needle 4 has a straight tube shape as shown in FIG. 7, when the needle 9 is sucked into the needle 4 when the tip 9 is punctured into the skin including the hair 2, the amount of blood is sucked into the needle 4. The suction | attraction with the donor 9 has generate | occur | produced the malfunction that the attracted blood becomes easy to adhere to the inner wall of the needle 4 formed in the internal diameter (phi) 1.0-1.4mm range. When such a defect occurs, the sucked donor 9 adheres to the inner wall portion of the needle 4 to which blood is adhered, and the sucked donor 9 is clogged into a lump. Such a portion where the donor 9 is clogged was supposed to occur frequently on the proximal end side of the needle 4.

こうした不具合を解消するため、本願の発明者は、ニードル内の詰まりを少なくするため、ニードルの先端の円筒形切込口の形状を、先端部から基端部へとテーパ状に拡開する尖鋭状のものとし、ニードルを毛髪２を中心とする皮膚に穿刺し、穿開する際の出血量を極力少量にする等の方法を試みる実験を行った。しかしながら、こうした先端を先鋭状の切込口としてニードルを形成した場合、確かに最初のうちは切込口を皮膚に穿刺し、穿開した際の出血量は少なくなるものの、先端が先鋭状とされる切込口が挫滅し易くなり、先端の先鋭部が内周方向に変形する不具合が多く発生した。すなわち、切込口にこうした変形が発生すると皮膚に穿刺し、穿開する際の出血量が多くなり、ニードルを交換する頻度は以前の直管状のニードル４に比して、大きく改善されなかった。   In order to eliminate such problems, the inventor of the present application reduces the clogging in the needle, and in order to reduce the clogging in the needle, the shape of the cylindrical cutout at the tip of the needle is sharpened to expand in a tapered shape from the distal end portion to the proximal end portion. An experiment was conducted in which a needle was punctured into the skin centered on the hair 2 and a method of reducing the amount of bleeding at the time of puncture as much as possible was performed. However, when a needle is formed with such a tip as a sharp cut-out, it will certainly reduce the amount of bleeding when the cut is pierced into the skin at first, but the tip is sharp. As a result, there are many problems that the cut-out opening is easily annihilated, and that the tip of the tip is deformed in the inner circumferential direction. That is, when such a deformation occurs in the incision, the amount of bleeding when the skin is punctured and opened increases, and the frequency of replacing the needle is not greatly improved compared to the previous straight tubular needle 4. .

本願の発明者はさらにこうした先端に尖鋭状部を形成するのに加え、様々な加工を加えた結果、内部にドナーが詰まることなく、スムーズにドナーの吸引を行うことができる毛髪移植用具のためのニードルを開発することができた。   In addition to forming a sharp portion at the tip, the inventor of the present application is a hair transplantation device that can smoothly suck a donor without clogging the donor inside as a result of various processing. Of needles could be developed.

すなわち、本発明は、毛髪を含むドナーが内部に詰まることなく、スムーズにドナーの吸引を行うことができる毛髪移植用具のためのニードルを提供することを目的としている。   That is, an object of the present invention is to provide a needle for a hair transplantation device that can smoothly suck a donor without clogging the donor including the hair.

以下、本発明を実施するための最良の形態を図面に基づいて説明する。先ず図２に示す毛髪移植用具２０は患者の頭皮のうち、毛髪がない領域あるいは毛髪が少ない領域に対し、その患者の他の領域にある比較的生命力の強い毛髪の毛根およびその周部領域を含む皮膚をドナーとして採取して移植する際に使用され、ドナーとして採取する毛髪２を中心として、その周部の皮膚に穿刺され、その部分の皮膚を穿開して吸引し、採取するためのものである。   Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. First, the hair transplantation tool 20 shown in FIG. 2 shows the hair root and the peripheral region of a relatively strong vital force in the other region of the patient with respect to the region where the hair is not present or the region where the hair is small in the scalp of the patient. Used for collecting and transplanting the skin containing the donor as a donor, for puncturing the skin around the periphery of the hair 2 to be collected as the donor, for opening the skin of that part, suctioning, and collecting Is.

この毛髪移植用具２０は、先端の内部にドナーとして採取する毛髪２を中心として、その周部の穿刺され、先端に円筒形の切込口２１を備える全体管状のニードル２２を備える。ニードル２２は図１に示すように全体長尺状からなる管状のものとされ、移植用具２０の内部に交換可能に取付可能とされる。 The hair transplantation device 20 includes a generally tubular needle 22 that is punctured around the hair 2 collected as a donor inside the tip and includes a cylindrical cutout 21 at the tip. As shown in FIG. 1, the needle 22 is formed into a tubular shape having an overall long shape, and can be attached to the inside of the transplantation device 20 in a replaceable manner.

移植用具２０には、先端の内部に取り付けられるニードル２２の切込口２１が対応する皮膚領域に穿刺された状態において、該ニードル２２を軸回り（図２のＡ方向）に回転可能とし、ドナー領域の皮膚を切込口２１により穿開可能とする回転駆動手段としてのモータ２３が備えられる。さらに移植用具２０には、モータ２３によるニードル２２の軸回りの回転により穿開されて、切込口２１内に留置されるドナー領域の皮膚を、吸引エアにより切込口２１からニードル２２の内部にドナーとして吸引し、さらにニードル２２から該ニードル２２に管路２４を介して接続されるチューブ２５により、ドナー貯留部としての採取容器（不図示）へと矢印Ｃ方向に搬送するための吸引手段としてのポンプ（不図示）が備えられる。 In the transplant device 20, the needle 22 attached to the inside of the distal end can be rotated around the axis (direction A in FIG. 2) in a state where the cut-out opening 21 of the needle 22 is pierced into the corresponding skin region. A motor 23 is provided as a rotation driving means for enabling the skin of the region to be opened by the cut opening 21. Further, the transplant tool 20 is opened by rotation of the needle 22 around the axis of the needle 22 by the motor 23, and the skin of the donor region placed in the cut opening 21 is sucked into the inside of the needle 22 from the cut opening 21 by suction air. A suction means for sucking in as a donor and transporting in the direction of arrow C to a collection container (not shown) as a donor reservoir by a tube 25 connected from the needle 22 to the needle 22 via a conduit 24 As a pump (not shown).

すなわち移植用具２０によるドナーの採取は、モーター２３を作動させてニードル２２を軸回りに矢印Ａ方向に回転させ、ニードル２２の切込口２１を数mm程度頭皮に対し法線方向（矢印Ｂ方向）に穿刺し、毛根を含むドナー９を切込口２１内に保持させる。この状態で吸引手段としてのポンプの作動により、切込口２１内の皮膚を矢印Ｃ方向に吸引し、ニードル２２の内部に吸引する。 In other words, donors are collected by the transplantation device 20 by operating the motor 23 to rotate the needle 22 around the axis in the direction of arrow A, and the incision 21 of the needle 22 is in the direction normal to the scalp (in the direction of arrow B). ) And the donor 9 including the hair root is held in the incision 21. In this state, the skin in the incision 21 is sucked in the direction of arrow C by the operation of the pump as the suction means, and sucked into the needle 22.

ニードル２２内に吸引されたドナー９は、管路２４を介してチューブ２５へと搬送され、さらに採取容器（不図示）へと搬送されて貯留される。採取容器内にある程度の量のドナー９が捕集された状態において該容器を開け、容器内のネットに捕集されたドナー９を採取して移植先の頭皮に移植するようにする。 The donor 9 sucked into the needle 22 is transported to the tube 25 via the conduit 24, and further transported to a collection container (not shown) and stored. In a state where a certain amount of donor 9 is collected in the collection container, the container is opened, and the donor 9 collected in the net in the container is collected and transplanted to the scalp of the transplant destination.

移植用具２０に交換可能に取付けられるニードル２２は、図２に示すように先端側からモータ２３を貫挿する状態で矢印Ｃ方向に挿入して接続され、このためニードル２２には図１に示すようにモータ２３の軸に取付けるための支持体２６Ａ、２６Ｂが外装されている。ニードル２２は、先端の円筒形の切込口２１が形成される部分において、先端部から基端部へ角度θ１をもってテーパ状に拡開する尖鋭状部２７を備えてなる（図３参照）。 As shown in FIG. 2, the needle 22 attached to the transplantation device 20 in an exchangeable manner is inserted and connected in the direction of arrow C with the motor 23 inserted through from the distal end side. For this reason, the needle 22 is shown in FIG. Thus, supports 26A and 26B for mounting on the shaft of the motor 23 are externally provided. The needle 22 includes a pointed portion 27 that expands in a tapered shape at an angle θ1 from the distal end portion to the proximal end portion at a portion where the cylindrical cutout 21 at the distal end is formed (see FIG. 3).

拡開する尖鋭状部２７のテーパ角度θ１は、１０〜２０度程度とされ、また尖鋭状部２７のニードル２２の先端部を基端とする軸線方向での長さＬ１（図４参照）は、０．３mmから１．２mm程度の範囲のものとされる。尖鋭状部２７の形成は、中空針材の先端の外側をグラインダで研磨したり、溶解して行われる。   The taper angle θ1 of the sharpened portion 27 that expands is about 10 to 20 degrees, and the length L1 (see FIG. 4) in the axial direction with the distal end portion of the needle 22 of the sharpened portion 27 as the base end is set. In the range of about 0.3 mm to 1.2 mm. The sharpened portion 27 is formed by polishing or melting the outside of the tip of the hollow needle material with a grinder.

ニードル２２は、この尖鋭状部２７が形成される先端側の長さ領域Ｌ３に対し、基端側の長さ領域Ｌ４の外径が大きくなるように設定して形成される。すなわち、ニードル２２は、直管状の中空針材の先端側を絞り加工し、尖鋭状部２７が形成される先端側の長さ領域Ｌ３においてその管内径Ｄ１を小さくし、基端側の長さ領域においてその管内径Ｄ２が大径になるよう設定して加工形成される。   The needle 22 is formed such that the outer diameter of the length region L4 on the proximal end side is set larger than the length region L3 on the distal end side where the sharpened portion 27 is formed. That is, the needle 22 is drawn at the distal end side of the straight tubular hollow needle material, and the tube inner diameter D1 is reduced in the distal end length region L3 where the sharpened portion 27 is formed, and the proximal end length is reduced. In the region, the tube inner diameter D2 is set so as to be a large diameter and processed.

すなわちニードル２２は、先端側の軸線方向での長さ領域Ｌ３を１０mmないし１５mm程度とし、その部分の管内径Ｄ１をφ０．８mm〜φ１．２mm程度になるよう形成している。一方先端側の長さ領域Ｌ３に対する基端側の軸線方向での長さ領域Ｌ４を１２０mmないし１４０mmとし、その部分の管内径をφ１．２mm〜φ１．４mm程度になるよう形成している。   That is, the needle 22 is formed such that the length region L3 in the axial direction on the distal end side is about 10 mm to 15 mm, and the tube inner diameter D1 of that portion is about φ0.8 mm to φ1.2 mm. On the other hand, the length region L4 in the axial direction on the proximal end side with respect to the length region L3 on the distal end side is set to 120 mm to 140 mm, and the inner diameter of the tube is formed to be about φ1.2 mm to φ1.4 mm.

さらに尖鋭状部２７が形成される切込口２１の最先端部には、管内壁側から管外壁側から管外壁側方向へ前記尖鋭状部２７と逆方向に最先端部に向けて角度θ２において拡開する逆テーパ部２８が形成される（図４の拡大部分参照）。逆テーパ部２８の拡開角度θ２は１０〜２０度程度とされ、また逆テーパ部２８のニードル２２の先端部の基端とする軸線方向での長さＬ２（図４の拡大部分参照）は、１０〜３０μmの範囲で形成される。逆テーパ部２８の形成は図３に示すようにニードル２２の先端の切込口２１に斜歯状のグラインダ３０を挿入し、研磨することにより形成される。   Further, the cutting edge 21 where the sharpened portion 27 is formed has an angle θ2 at the angle θ2 from the inner wall side of the tube toward the outermost portion in the direction opposite to the sharpened portion 27 from the outer wall side of the tube toward the outer wall side of the tube. The reverse taper part 28 which expands is formed (see the enlarged part in FIG. 4). The expansion angle θ2 of the reverse taper portion 28 is about 10 to 20 degrees, and the length L2 in the axial direction of the reverse taper portion 28 as the base end of the distal end portion of the needle 22 (see the enlarged portion in FIG. 4) is , In the range of 10-30 μm. The reverse taper portion 28 is formed by inserting a bevel-shaped grinder 30 into the cut-out opening 21 at the tip of the needle 22 and polishing as shown in FIG.

こうして形成されるニードル２２によると、先ず先端部から基端部へとテーパ状に拡開する尖鋭状部２７を備えることとし、さらに該尖鋭状部２７における最先端部に管内壁側から管外壁側方向へ尖鋭状部２７と逆方向に最先端部に向けて拡開する逆テーパ部２８を備えることとしたため、長い期間使用した場合においても切込口２１における挫滅変形の発生が少なく、交換頻度を少なくすることが可能となる。 According to the needle 22 formed in this way, first, it is provided with the sharpened portion 27 that expands in a tapered shape from the distal end portion to the proximal end portion, and further, the outermost wall of the sharpened portion 27 from the inner wall side to the outer tube wall. Since the sharpened portion 27 in the lateral direction and the reverse tapered portion 28 that expands in the opposite direction toward the most distal portion are provided, even when used for a long period of time, there is little occurrence of crushing deformation in the incision 21 and replacement The frequency can be reduced.

また先端が尖鋭状とされるため、皮膚に穿刺し、穿開した場合における出血量が少なくなり、また速やかなドナー９の吸引が可能となるため、従来のように血液を吸引することにより発生していたドナー９のニードル内での詰まりを抑制することが可能となる。特に、本願の発明者が様々なサイズのニードルを形成する試行錯誤を繰り返す中、上記実施形態に示すように尖鋭状部２７の長さＬ１を０．３mm〜１．２mmとし、テーパ角度θ１を１０〜２０度とするのが最も良好に詰まりを抑制することが可能となった。   In addition, since the tip is sharp, the amount of bleeding is reduced when the skin is punctured and opened, and the donor 9 can be quickly aspirated. It is possible to suppress clogging of the donor 9 in the needle. In particular, while the inventor of the present application repeats trial and error to form needles of various sizes, the length L1 of the sharpened portion 27 is set to 0.3 mm to 1.2 mm as shown in the above-described embodiment, and the taper angle θ1 is set. It became possible to suppress clogging best by setting it to 10 to 20 degrees.

また逆テーパ部２８の軸線方向での長さＬ２に関しても１０〜３０μmとし、かつテーパ角度θ２についても１０〜２０度程度とするのが最も良好に詰まりを抑制することが可能となった。   In addition, the length L2 in the axial direction of the reverse taper portion 28 is set to 10 to 30 μm, and the taper angle θ2 is set to about 10 to 20 degrees to most effectively suppress clogging.

さらに実施形態に係るニードル２２によると、先端部から基端部へとテーパ状に拡開する尖鋭状部２７を備えることとし、さらに該尖鋭状部２７における最先端部に管内壁側から管外壁側方向へ尖鋭状部２７と逆方向に最先端部に向けて拡開する逆テーパ部２８を備えることに加えて、さらに尖鋭状部２７が形成される先端側の長さ領域Ｌ３に対し、基端側全体の長さ領域Ｌ４の管内径をＤ１からＤ２と大径になるよう設定し、形成したため、ニードル２２の基端部において吸引したドナー９が詰まることもない。こうした現象は、恐らくニードル２２が先端から基端部に向けて拡開することにより、ニードル２２内で乱流が発生し、しかも基端部が大径となるのでドナー９の血液が付着する割合が少なくなることに起因することによるものと推測される。   Further, according to the needle 22 according to the embodiment, the sharpened portion 27 that expands in a tapered shape from the distal end portion to the proximal end portion is provided, and further, the outermost wall of the sharpened portion 27 from the inner wall side to the outer tube wall. In addition to having a reverse tapered portion 28 that expands toward the most distal portion in the opposite direction to the sharp portion 27 in the lateral direction, in addition to the length region L3 on the tip side where the sharp portion 27 is further formed, Since the tube inner diameter of the entire length region L4 of the proximal end side is set so as to increase from D1 to D2, the donor 9 sucked at the proximal end portion of the needle 22 is not clogged. This phenomenon is probably due to the rate at which the blood of the donor 9 adheres because the needle 22 expands from the distal end toward the proximal end to generate turbulent flow in the needle 22 and the proximal end has a large diameter. It is presumed that this is due to the fact that there is less.

以上の実施形態によれば、毛髪を含むドナーが内部に詰まることなく、スムーズにドナーの吸引を行うことができる毛髪移植用具のためのニードルを提供することが可能となる。   According to the above embodiment, it is possible to provide a needle for a hair transplantation device that can smoothly suck a donor without clogging a donor including hair.

本発明は、毛髪移植手術において、ドナーとしての毛髪を採取する作業を円滑かつ短時間に行うことができ、その分毛髪の生着率の向上が図られることになる。よって自毛による頭髪の再生手術の信頼性を高めることが可能となる。   According to the present invention, in the hair transplantation operation, the operation of collecting hair as a donor can be performed smoothly and in a short time, and the survival rate of the hair can be improved accordingly. Therefore, it becomes possible to improve the reliability of the regenerating operation of the hair with the own hair.
