従来、頭部等の毛髪の薄い部分や負傷等により毛髪が失われた部分に、後頭部等のように毛髪が密生している部分から毛髪を採取し、これを1本ないし3本程度にばらばらにして植毛することが行われている。
しかしながら、医師が手作業により毛を1本ずつ植えていくのであるから手術に長時間を要するという不都合があった。
【0003】
【発明が解決しようとする課題】
本発明は、かかる不都合を解消することを目指すものであって、短時間で植毛することができる連続植毛機を提供することを目的とする。
【0004】
【課題を解決するための手段】
ケース(1)の前面に取り付けられ、先端部(18)が斜め方向にそがれていて中空管に形成された針(17)と、トリガー(5)の操作により針(17)の内部を前進して毛髪(H)を押し出すことができるプッシュ・ロッド(7)と、プッシュ・ロッド(7)の前進に連動して針(17)に沿って前進し、針(17)の先端部(18)を植毛部位の定位置に保持することができる押え片(13)とを備え、多数の円形の穴(23)と多数の歯(24)を設けた円盤(22)をケース(1)の外部に回転自在に支持し、歯(24)を1ピッチずつ送ることができる円盤送り機構(21)を備えたことを特徴とする。
【0005】
【発明の実施の形態】
添付の図面を参照しつつ本発明の実施の形態を詳説する。
図1は本発明の連続植毛機が作動しない状態における側面図である。連続植毛機のケース1に細長い溝2が設けられ、溝2にスライダ3が摺動自在に嵌装されている。ケース1に固着された軸4の周りに揺動自在にトリガー5が設けられ、トリガー5の一端はスライダ3に係合しているので、トリガー5を操作することによりスライダ3を摺動させることができる。トリガー5は引張りばね6により牽引されているので、スライダ3は常時溝2の右端に位置している。
スライダ3には細長いプッシュ・ロッド7とL字形の作動杆8が設けられている。プッシュ・ロッド7は毛髪Hを押し出すロッドであり、作動杆8は押え機構9(後述する。)を作動させる杆である。
10はケース1に固着されたグリップであり、グリップ10にはトリガー5の後退動を制限するストッパ11が設けられている。
【0006】
次に、押え機構9の構成について説明する。ロッド12の先端に押え片13が取り付けられている。14はロッド12を常時後方(右方向)へ付勢するばねである。
ケース1の前面に前支柱15が取り付けられ、前支柱15には突出部16が設けられ、突出部16の外周におねじが刻設されている。細長い中空管に形成された針17の先端部18は斜め方向にそがれている。針17の後方は大径部19に形成され、大径部19の後端にはつばが形成されている。20は袋ナットで、大径部19の後端のつばを押えて突出部16のおねじに螺合して針17を固定支持する。押え片13には円孔が設けられていて針17を貫通させ、ロッド12はばね14により後方(右方向)に付勢されているので、押え片13は不作動時は針17の大径部19に当接している。
21は円盤送り機構(後述する。)で、円盤22には多数の円形の穴23があけられている。円盤22は合成樹脂製が望ましい。
【0007】
図2は医師がトリガー5を引いて植毛を実行しているところを示す側面図であり、図2に付されている符号は図1に付されている符号と同一部材を指している。
トリガー5を反時計方向に揺動させると、スライダ3は溝2内を前方(左方向)へスライドし、スライダ3に固着されたプッシュ・ロッド7は前方(左方向)へ進行する。作動杆8はロッド12を押すので、ロッド12の先端に取り付けられた押え片13は針17に案内されて前方(左方向)へ移動する。
【0008】
図3は円盤22を1ピッチずつ回転させる円盤送り機構21を前方から見た正面図である。
図4は円盤送り機構21を矢印A(図1をみよ。)の方向から見た背面図である。
円盤送り機構21の詳細構造は次のとおりである。図3及び図4において、揺動腕26は前方揺動腕26aと側板26bと後方揺動腕26cにより細長いコ字状に形成されており、これが前支柱15とケース1にまたがって揺動自在に支持されている。前方揺動腕26aと後方揺動腕26cの間に架け渡された軸29に爪28が回動自在に支持され、爪28は側板26bに取り付けられたばね30(図4)によって円盤22の方向に常時付勢されている。27は揺動腕を揺動させる把手である。
【0009】
31は揺動制限部材を示す。揺動制限部材31の詳細構造は次のとおりである。図4において、ケース1に支持板32が取り付けられ、支持板32に揺動調整ねじ33と支柱34が取り付けられている。後方揺動腕26cと一体的にL字部26dが形成され、揺動調整ねじ33はL字部26dの揺動に対するストッパとして働く。揺動調整ねじ33を回動させることにより揺動腕26の揺動角を精密に微調整することができる。L字部26dには支柱34を貫通させる穴が設けられ、支柱34には復元ばね35が嵌挿されている。把手27を押し下げるとL字部26dが揺動調整ねじ33の頭部に当接して、揺動は停止する。把手27を放すと、復元ばね35の復元力によって揺動腕26は時計方向(図4)に揺動し、L字部26dが支柱34の頭部に当接して揺動が停止する。
【0010】
爪28が円盤の歯を1ピッチずつ送る態様を図5(a)〜(d)について説明する。爪28はばね30によって常時時計方向に付勢されているので、医師が把手27を押し下げると、爪28の先端が歯▲3▼と歯▲2▼の間の凹所に落ち込み(図5(b))、爪28の揺動に伴って歯▲2▼を1ピッチだけ回動させる(図5(c))。この図5(c)の時期は、図4においてL字部26dが揺動調整ねじ33の頭部に当接する時期と一致する。医師が指を把手27から離すと、揺動腕26は復元ばね35の復元力によって時計方向に揺動するが、L字部26dは支柱34の頭部に当接して停止する(図4)。この期間中、爪28はばね30を圧縮しながら歯▲3▼を乗り越えて歯▲4▼の上面に至って停止する(図5(d))。その後は同じ動作を繰り返して円盤22を1ピッチずつ送って行く。
【0011】
次に、連続植毛の手順について説明する。
事前の準備として、後頭部等のように毛髪が密生している部分から毛髪を採取し、これを1本ないし3本程度にばらばらにしておく。図1において、円盤22をケース1から取り外して毛髪をすべての穴23の中に入れた後、円盤22を再びケース1に取り付ける。
他方、図6は図2のB部の説明的拡大図であり、患者の頭皮に穴あけ用の特殊メスにより多数の穴を予め穿設しておく。穴の深さは真皮の下部ないし脂肪層の上部に達する深さが望ましい。
医師が連続植毛機の針17の先端を頭皮に穿けた穴に挿入し、トリガー5を引くとプッシュ・ロッド7が前進して毛髪Hを押し進め、押え片13もプッシュ・ロッド7の前進に連動して針17に沿って前進する。医師が押え片13を表皮に当接すると連続植毛機の位置が安定し、このとき、毛髪Hはプッシュ・ロッド7により針17の外へ押し出されて、その毛根が脂肪層ないしはその近傍に植毛される。
医師がトリガー5を放すと、トリガー5は引張りばね6に牽引されて時計方向に揺動して図1の位置に復帰する。ロッド12もばね14の復元力により右方向へ移動して押え片13は大径部19に当接する。毛髪Hはプッシュ・ロッド7により押し出されるときに圧縮されるが、針17が穴から引き抜かれると、植毛された毛髪は自身の有する弾力により穴の中でほぼ直線状に復元する。
【0012】
次に、医師が揺動腕26の把手27を下方へ押すと、爪28が円盤22の歯▲2▼を丁度1ピッチ回動させた時に揺動腕26のL字部26dが揺動調整ねじ33に当接して円盤22の回動が停止する(図4及び図5(a)〜(d)参照)。
医師が揺動腕26の把手27を放すと、支柱34(図4)に嵌挿された復元ばね35の復元力により揺動腕26を図4の位置に復帰させる。揺動腕26の揺動に伴って、爪28は歯▲3▼を乗り越えて、図5(d)に示すとおり、歯▲4▼の歯先上に復帰する。
以上に述べた手順を繰り返すことにより、毛髪Hを次々と頭皮に植毛することができる(図6)。
【0013】
【発明の効果】
円盤22はケース1の外部に設けてあるので、円盤22に毛髪収納用の穴23、23・・・を多数あけることができ、したがって多数の毛髪を連続的に高速度で植毛することができる。

Reference numeral 10 denotes a grip fixed to the case 1, and the grip 10 is provided with a stopper 11 for restricting the backward movement of the trigger 5.
[0006]
Next, the structure of the presser mechanism 9 will be described. A presser piece 13 is attached to the tip of the rod 12. Reference numeral 14 denotes a spring that constantly biases the rod 12 backward (to the right).
A front support 15 is attached to the front surface of the case 1, and a protrusion 16 is provided on the front support 15. A screw is engraved on the outer periphery of the protrusion 16. The tip 18 of the needle 17 formed in the elongated hollow tube is tilted in an oblique direction. The rear of the needle 17 is formed in a large diameter portion 19, and a collar is formed at the rear end of the large diameter portion 19. A cap nut 20 presses the collar at the rear end of the large-diameter portion 19 and is screwed into the male screw of the protruding portion 16 to fix and support the needle 17. Since the presser piece 13 is provided with a circular hole to allow the needle 17 to pass therethrough and the rod 12 is urged rearward (rightward) by the spring 14, the presser piece 13 has a large diameter of the needle 17 when not operating. It is in contact with the part 19.
Reference numeral 21 denotes a disk feeding mechanism (described later), and a large number of circular holes 23 are formed in the disk 22. The disk 22 is preferably made of synthetic resin.
[0007]
FIG. 2 is a side view showing that the doctor pulls the trigger 5 to perform hair transplantation, and the reference numerals in FIG. 2 indicate the same members as those in FIG.
When the trigger 5 is swung counterclockwise, the slider 3 slides forward (leftward) in the groove 2 and the push rod 7 fixed to the slider 3 advances forward (leftward). Since the operating rod 8 pushes the rod 12, the presser piece 13 attached to the tip of the rod 12 is guided by the needle 17 and moves forward (leftward).
[0008]
FIG. 3 is a front view of the disk feeding mechanism 21 that rotates the disk 22 by one pitch, as viewed from the front.
FIG. 4 is a rear view of the disk feeding mechanism 21 as seen from the direction of arrow A (see FIG. 1).
The detailed structure of the disk feeding mechanism 21 is as follows. 3 and 4, the swing arm 26 is formed in an elongated U shape by a front swing arm 26 a, a side plate 26 b, and a rear swing arm 26 c, and can swing freely across the front column 15 and the case 1. It is supported by. A claw 28 is rotatably supported on a shaft 29 spanned between the front swing arm 26a and the rear swing arm 26c, and the claw 28 is directed to the disk 22 by a spring 30 (FIG. 4) attached to the side plate 26b. Is always energized. A handle 27 swings the swing arm.
[0009]
Reference numeral 31 denotes a swing limiting member. The detailed structure of the swing limiting member 31 is as follows. In FIG. 4, a support plate 32 is attached to the case 1, and a swing adjustment screw 33 and a support column 34 are attached to the support plate 32. An L-shaped portion 26d is formed integrally with the rear swing arm 26c, and the swing adjustment screw 33 functions as a stopper against swinging of the L-shaped portion 26d. By turning the swing adjustment screw 33, the swing angle of the swing arm 26 can be finely adjusted precisely. The L-shaped portion 26 d is provided with a hole through which the support 34 is passed, and a restoring spring 35 is fitted into the support 34. When the handle 27 is pushed down, the L-shaped portion 26d comes into contact with the head of the swing adjustment screw 33, and swinging stops. When the handle 27 is released, the swinging arm 26 swings in the clockwise direction (FIG. 4) by the restoring force of the restoring spring 35, and the L-shaped portion 26d abuts against the head of the column 34 and stops swinging.
[0010]
The manner in which the claw 28 feeds the teeth of the disk one pitch at a time will be described with reference to FIGS. Since the nail 28 is constantly urged clockwise by the spring 30, when the doctor pushes down the handle 27, the tip of the nail 28 falls into the recess between the teeth (3) and (2) (FIG. 5 ( b)), the tooth {circle around (2)} is rotated by one pitch as the claw 28 swings (FIG. 5C). The timing shown in FIG. 5C coincides with the timing when the L-shaped portion 26d contacts the head of the swing adjustment screw 33 in FIG. When the doctor removes the finger from the handle 27, the swing arm 26 swings in the clockwise direction by the restoring force of the restoring spring 35, but the L-shaped portion 26d comes into contact with the head of the column 34 and stops (FIG. 4). . During this period, the claw 28 gets over the tooth (3) while compressing the spring 30, reaches the upper surface of the tooth (4) and stops (FIG. 5 (d)). Thereafter, the same operation is repeated and the disk 22 is sent one pitch at a time.
[0011]
Next, the procedure for continuous flocking will be described.
As a preliminary preparation, hair is collected from a portion where hair is dense, such as the back of the head, and is separated into about 1 to 3 pieces. In FIG. 1, the disk 22 is removed from the case 1 and the hair is put into all the holes 23, and then the disk 22 is attached to the case 1 again.
On the other hand, FIG. 6 is an explanatory enlarged view of part B of FIG. 2, and a number of holes are previously drilled in the scalp of the patient with a special knife for drilling. The depth of the hole is preferably a depth that reaches the lower part of the dermis or the upper part of the fat layer.
When the doctor inserts the tip of the needle 17 of the continuous hair transplanter into the hole made in the scalp and pulls the trigger 5, the push rod 7 advances to push the hair H forward, and the presser piece 13 is also linked to the advance of the push rod 7. Then, it advances along the needle 17. When the doctor abuts the presser foot 13 against the epidermis, the position of the continuous hair transplanter is stabilized. At this time, the hair H is pushed out of the needle 17 by the push rod 7, and the hair root is implanted in the fat layer or the vicinity thereof. Is done.
When the doctor releases the trigger 5, the trigger 5 is pulled by the tension spring 6 and swings clockwise to return to the position shown in FIG. The rod 12 also moves to the right by the restoring force of the spring 14, and the presser piece 13 contacts the large diameter portion 19. The hair H is compressed when it is pushed out by the push rod 7, but when the needle 17 is pulled out of the hole, the implanted hair is restored to a substantially straight shape in the hole by its elasticity.
[0012]
Next, when the doctor pushes the handle 27 of the swinging arm 26 downward, the L-shaped portion 26d of the swinging arm 26 swings and adjusts when the claw 28 rotates the tooth (2) of the disk 22 just one pitch. The rotation of the disk 22 stops upon contact with the screw 33 (see FIGS. 4 and 5A to 5D).
When the doctor releases the handle 27 of the swing arm 26, the swing arm 26 is returned to the position shown in FIG. 4 by the restoring force of the restoring spring 35 inserted into the column 34 (FIG. 4). As the swing arm 26 swings, the claw 28 moves over the tooth (3) and returns to the tooth tip of the tooth (4) as shown in FIG.
By repeating the procedure described above, the hair H can be implanted in the scalp one after another (FIG. 6).
[0013]
【The invention's effect】
Since the disk 22 is provided outside the case 1, a large number of holes 23, 23... For storing hair can be formed in the disk 22, so that a large number of hairs can be implanted continuously at a high speed. .
