Abstract

A scalpel (11) having a sharp tip end, a guide pipe (12) adjacent to the scalpel and an insertion needle (13) having a hair rood drawing portion (13a) at the tip end thereof passing through the guide pipe are all provided inside a body (10) so as to be able to project from the body. The hair root drawing portion (13a) hooks on the root (31a) of a hair (31) to thereby insert the insertion needle into the guide pipe. The scalpel is allowed to project a specified length from within the body so as to advance into a subcutaneous tissue (46) and the guide pipe having the insertion needle thereinside is allowed to advance into the subcutaneous tissue through an incision made by the scalpel. While the insertion needle is left in the subcutaneous tissue (46) to allow the hair root to be retained by the hair root drawing portion, the scalpel and the guide pipe are restored into the body and then the insertion needle is restored. Hair roots can be uniformly transplanted with little bleeding, without being smashed, and in a short time, to thereby grow the hairs in normal shapes.

Description

Technical Field Flocking method and flocking device

TECHNICAL FIELD The present invention relates to a hair transplanting method and a hair transplanting device for transplanting hairs with hair roots one by one to necessary parts of a body. Background art

Conventionally, when hair, eyebrows, etc. become thin with age or are lost due to injury, etc., the part where the hair is dense, such as the back of the head, is cut off using a scalpel, and the hair root is collected from this part. A hair transplanting method of implanting a hair root into thinned skin such as hair is known. One of the flocking methods is a single flocking method that makes the hairline feel more natural.

Furthermore, in this single hair transplantation method, a part where many hairs including hair roots are densely grown is cut off from the skin such as the occipital region, and the hairs are arranged one by one, and the hair is implanted with a needle, a scalpel, or the like on the epidermis. After drilling holes, there is a method in which the hair roots arranged side by side are pinched one by one with tweezers and pressed into the holes drilled in the epidermis. However, in this method, if the hair root is pinched with tweezers, the hair root is damaged and the survival rate of the hair tends to be low, and if a hole is made in the epidermis with a syringe needle or a scalpel, the position of the hole is difficult to understand due to bleeding There was a problem.

Conventionally, Japanese Patent Application Laid-Open No. HEI 4-152924 discloses a hair transplanter for solving this problem. As shown in Fig. 16, in this flocking device, a hollow flocking needle 2 having a sharp tip is attached to the distal end of the body 1 with a screw 3, and a slit 2a is provided at the distal end of the flocking needle 2. . A core shaft 4 that penetrates a flocking needle and projects a predetermined length is inserted into the body main body 1 so as to be able to protrude and retract. The mandrel 4 is housed in the flocked needle 2 by the elastic force of the spring 5, and an operation part 6 of the mandrel 4 is provided at the upper end of the body 1. When implanting using this implanter, insert the root 7a of the hair 7 into the implanted needle 2 according to the slit 2a as shown in Fig. 17 (a). After that, the flocking needle 2 is inserted into the epidermis 8 at the position where the flocking is to be performed. Then, as shown in Fig. 17 (b), the body body 1 (Fig. 16) is pulled up while pressing the operation part 6 (Fig. 16) of the core shaft 4, and the follicle 6a is It is pushed into the formed hole 8. Next, as shown in FIG. 17 (c), when the hair implantation needle 2 is detached from the epidermis 8, the hair 7 with the hair root 7a is transplanted into the subcutaneous tissue.

However, in the above-mentioned conventional hair transplanter, when the hollow hair implantation needle 2 is pierced into the epidermis 8, a part of the epidermis is cut off, so that bleeding is apt to occur. is there. Further, since the hair root 7a is pushed by the core shaft 4, the hair root is clogged in the flocked needle 2, or the hair root is crushed and deformed. From the deformed hair root, there was a drawback that hair with a normal shape could not grow, for example, hair that had shrunk after hair transplantation.

FIG. 2A shows that the scalpel 11 is at the first position, the guide pipe 12 is at the second position, and the insertion needle 13 is at the third position.

As shown in FIG. 7, the scalpel 11 is an elongated flat plate having a width and thickness of, for example, about 2.5 mm and about 0.5 mm, and has a sharp V-shaped tip. As shown in FIG. 8, the guide pipe 12 has a cylindrical shape with an outer diameter and a wall thickness of, for example, about 1.3 mm and about 0.15 mm, and has a diagonally cut end. Further, as shown in the dashed line in FIG. 6 and in FIG. 9, the insertion needle 13 has a thickness of, for example, about 1.0 mm and has a follicle retracting portion 13a bent diagonally upward at the tip thereof. The root portion 13a and the needle body 13b of the insertion needle form an obtuse angle.

Returning to FIG. 1, inside the body 10, a female actuator 16 for reciprocating the knife 11 and a guide actuator for reciprocating the guide pipe 12 are provided. 17 and an insertion needle actuator 18 for reciprocating the insertion needle 13 are provided. In this embodiment, the actuators 16 to 18 are air cylinders. These actuators may be constituted by a stepping motor other than an air cylinder, an electromagnetic solenoid, or the like. The toner rod 16 a of the cylinder 16 is a female 1 1 via the intermediate rod 21 Is connected to the base end. The piston rod 17 a of the air cylinder 17 is connected to the base end of the guide pipe 12 via the intermediate port 22. Further, the piston rod 18 a of the air cylinder 18 is connected to the proximal end of the insertion needle 13.

The three air cylinders 16 to 18 are controlled by the controller 25. The controller 25 is supplied with compressed air from an air pressure source 26, and a DC voltage is applied from a battery 27. The controller 25 is turned on and off by a switch 28 provided on the outer surface of the body 10. A skin suppressing portion 29 is provided on the outer surface of the tip of the body main body 10, and a ring-shaped skin contact portion 29 a is provided at the tip of the skin suppressing portion 29 to be in contact with the skin to be transplanted. The distance from the skin contact portion 29a to the opening 10b is shorter than the length of the scalpel 11, which will be described later, protruding from the opening 10b.

As shown in FIGS. 1 and 3, a through hole 19 is formed in the body main body 10 so as to cross the body main body 10, and the through hole 19 accommodates a force trigger 30. Is accepted. As shown in FIGS. 3 to 6, a plurality of hairs 31 having hair roots 31a are arranged in the cartridge 30 in the same direction. In this embodiment, seven hairs are arranged. However, the force bridging 30 of the present invention is not limited to seven hairs, and may be configured to arrange a greater number of hairs. The cartridge 30 has a hair arrangement table 32 and a follicle holding lid 33. In this embodiment, seven concave grooves 34 are formed on the upper surface of the hair arrangement table 32 at right angles to the longitudinal direction of the hair arrangement table 32 and parallel to each other. As shown in FIG. 6, one end of the groove 34 is formed shallow, and the rest is formed deep. A notch 36 is formed at the bottom of the other end of the concave groove 34. As shown in FIGS. 4 to 6, the upper surface of the follicle-suppressing lid 33 is formed flat, and seven convex portions 37 that can be inserted into the concave grooves 34 are formed on the lower surface thereof in parallel with each other.

As shown in FIGS. 3, 4, and 6, a rack 38 orthogonal to the groove is formed on the lower surface of the hair array base 32 where the groove 34 is formed shallowly. The lower surface of the hair arrangement table 32 excluding the rack 38 is formed flat. As shown in FIGS. 1 and 3, a pinion 39 rotatably mounted on a support shaft 39 a provided near one end of the through hole 19 of the body 10 is combined with the rack 38. . The pinion 3 9 has a dial 4 1 that is larger in diameter than this pinion and concentric with the pinion. Is formed. As shown in FIG. 3, a pin 42 engaging with the rack 38 is provided near the other end of the through hole 19 of the body 10. A spring 43 is provided at the lower end of the pin 42. Spring 43 biases pin 42 to engage rack 38.

A method of using the thus configured flocking device will be described.

First, as shown in FIGS. 4 and 5, the hairs 31 were arranged so that the hair roots 3 1 a were located in the notches 36 in all the seven concave grooves 3 4 of the hair arrangement table 32 of the cartridge 30. Thereafter, the convex portion 37 of the follicle suppressing lid 33 is inserted into the concave groove 34. Thus, the roots 31 a of the hairs 31 arranged in the grooves 34 are slightly suppressed by the convex portions 37. Next, as shown in FIG. 3, the cartridge 30 is inserted into the through hole 19 of the body 10. When the pinion 39 is engaged with the rack 38 and the dial 41 is turned by hand, the cartridge 30 is moved in a direction orthogonal to the longitudinal direction of the body 10. When the first notch 36 reaches the third position of the insertion needle 13, the rotation of the dial 41 is stopped. As a result, as shown in FIGS. 6 and 2 (a), the hair root 31a of the insertion needle 13 comes into contact with the hair root 31a.

Next, grasp the handle 10a of the body 10 into which the cartridge 30 has been inserted, and press the skin restraining portion 29 against the skin 45 to be planted as shown in Fig. 2 (a). . With reference to FIGS. 2 (a) to 2 (g), control of the error cylinders 16 to 18 by the controller 25 will be described below. When switch 28 shown in FIG. 1 is pressed, controller 25 starts control.

As shown in FIG. 2 (b), the air cylinder 18 inserts the insertion needle 13 at the third position into the guide pipe 12 and advances to the vicinity of the tip. As a result, the hair retraction portion 13a of the insertion needle 13 hooks the hair root 31a, and draws the hair 31 together with the insertion needle 13 into the guide pipe 12. Next, as shown in FIG. 2 (c), the jaw cylinder 16 causes the scalpel 11 at the first position to protrude from the opening 10b by a predetermined length to enter the fourth position of the subcutaneous tissue 46. . This forms a cut in the epidermis 45. Next, as shown in Figs. 2 (c) and (d), the air cylinders 17 and 18 simultaneously project the guide pipe 12 in the second position and the insertion needle 13 in this pipe from the opening 10b. Let it. Guide pipe 1 2 moves along knife 1 1 Therefore, the guide pipe 12 surely enters through the above-mentioned cut and reaches the fifth position in the subcutaneous tissue 46. The hair root retracting part 13a, on which the hair root 31a has been caught, reaches the sixth position in the subcutaneous tissue 46 without being deformed while protecting the hair root with the guide pipe 12.

In Fig. 2 (d), the guide pipe 12 is advanced to the fifth position in the subcutaneous tissue when the scalpel 11 is at the fourth position in the subcutaneous tissue 46, but the scalpel 11 starts to be pulled up. Or when the knife 11 is being pulled up, the guide pipe 12 may be made to enter together with the insertion needle 13. In this case, the knife and guide pipe will pass each other. Alternatively, the guide pipe 12 may be inserted together with the insertion needle 13 after the knife 11 is pulled up to the first position. Next, as shown in Fig. 2 (e), the air cylinders 16 and 17 pull up the knife 11 and the guide pipe 12 and return them to the first position and the second position, respectively. Store. At this time, the air cylinder 18 does not operate, and the follicle retraction portion 13a keeps the follicle 31a at the sixth position inside the subcutaneous tissue 46. Subsequently, the air cylinder 18 pulls up the insertion needle 13 as shown in FIG. 2 (f), returns to the third position as shown in FIG. 2 (g), and stores it in the body 10.毛 Because the follicle retraction portion 13a of the insertion needle 13 forms an obtuse angle with the needle body 13b, it can be smoothly removed from the follicle 31a. The ring-shaped skin contact portion 29 a of the skin holding portion 29 allows the portion to be planted to be accurately positioned. The epidermis abutment portion 29a is transferred to the next portion to be transplanted after flocking.

Subsequently, the user of the flocking device rotates the dial 41 and jolts the cartridge 30 while receiving a sense of moderation by the pin 42, and the next notch 36 becomes the third position of the insertion needle 13. When the position 3 is reached, stop turning the dial 41. Hereinafter, the operations of FIGS. 2 (a) to 2 (g) are repeated for a desired number of flocking.

The above three air cylinders 16 to 18 are the first embodiment It is controlled by the controller 25 as well as the state. A through-hole 62 a through which the insertion needle 53 can be inserted is formed at the end of the intermediate holes 61 to 63, and a step portion near the tip that elastically deforms the insertion needle 53 in the direction of pressing down. 6 2b is formed (Fig. 11 (a)) ₀

A through hole 59 is formed in the body 50 so as to cross the body 50 (FIG. 10), and a cartridge 70 is accommodated in the through hole 59 (FIG. 10). ~ Figure 14). In the cartridge 70, a number of hairs 31 each having a hair root 31a are arranged in the same direction (FIGS. 11 (a) and 14). As shown in detail in FIGS. 13 and 14, the cartridge 70 includes a hair arrangement table 72 and a hair body lid 73. The hair arranging table 7 2 has a plurality of hair root housings 7 4 extending in parallel with each other at predetermined intervals and a single hair body housing 7 7 capable of housing the hair body 3 1 b extending from the hair root 31 a. And The follicle receiving portion 74 is a circular hole (having a diameter of, for example, 0.8 to 1.3 mm) formed extending in a direction perpendicular to the longitudinal direction of the hair aligning table 72. A cutout 76 (with a width of, for example, 0.3 mm) into which the follicle retraction portion 53a of the insertion needle 53 can be inserted is formed on the upper surface. In addition, the hair lid 73 is inserted into the hair body housing part 77 so as to prevent the hair body 31 b housed in the hair body housing part 77 from protruding from the cartridge 70. Be composed. Further, a rack 78 extending in the longitudinal direction of the hair alignment table 72 is formed on the lower surface of the hair alignment table 72. This rack 78 has the same function as the rack of the first embodiment. Except for the above, the configuration is the same as that of the first embodiment.

A method of using the thus configured flocking device will be described.

First, as shown in FIGS. 13 and 14, all of the large number of hair root accommodating portions 74 of the hair arranging base 72 of the cartridge 70 accommodate the hair roots 31 a and the hair main body accommodating portion 77. After arranging the hairs 31 so as to accommodate the hair body 31b, the hair body lid 73 is inserted into the hair body housing portion 77. This prevents the hair body 31b from protruding from the cartridge 70. Next, as shown in Fig. 1 ◦, when the cartridge 70 is inserted into the through hole 59 of the body 50, the pinion 39 is engaged with the S rack 78, and when the dial 41 is turned by hand, the cartridge is removed. 7 0 Jog in the direction perpendicular to the longitudinal direction of the main body 50. When the first notch 76 reaches the locus drawn by the follicle retraction portion 53a when the insertion needle 53 moves, the rotation of the diaphor 41 is stopped.

With reference to FIGS. 11 (a) to (e) and FIGS. 12 (f) to (i), control of the air cylinders 16 to 18 by the controller 25 will be described below. When the switch 28 shown in FIG. 10 is pressed, the controller 25 starts the control. When the air cylinder 18 moves the insertion needle 53 in the direction indicated by the solid line arrow in Fig. 11 (a), the insertion needle 53 contacts the step 6 2b formed on the intermediate rod 62. As a result, the hair root retracting portion 53a pierces the hair root 31a in the cartridge 70 (FIG. 11 (b)). When the insertion needle 53 moves toward the opening 50b in this state, the follicle retraction part 53a is inserted into the guide pipe 52 with the follicle 31a hooked, and the guide pipe 5 It advances to near the tip of 2 (Fig. 11 (c)). At this time, the base end of the hair root retracting portion 53a passes through the slit 52a. Next, the air cylinder 16 causes the scalpel 51 at the first position to protrude from the opening 50b by a predetermined length to enter the fourth position of the subcutaneous tissue 46 (FIG. 11D). This forms a cut in the epidermis 45.

In this state, the air cylinder 16 retracts the knife 51 from the fourth position, and at the same time, the air cylinders 17 and 18 open the guide pipe 52 in the second position and the insertion needle 13 in the pipe 52. Protrude from part 10b (Fig. 11 (e)). In this case, the scalpel 51 and the guide pipe 52 pass each other, that is, almost simultaneously with the scalpel 51 exiting the cut, the guide pipe 52 enters the subcutaneous tissue 46 from this cut, so that the cut is minimized. Size can be suppressed. As a result, hair can be transplanted with less bleeding than in the first embodiment. The above-mentioned guide pipe 52 reaches the fifth position in the subcutaneous tissue 46, and the hair root retracting portion 53a on which the hair root 31a is hooked is deformed while protecting the hair root 31a with the guide pipe 52. Instead, it reaches the sixth position in the subcutaneous tissue 46 (FIG. 12 (f)). On the other hand, the knife 51 reaches the first position. FIG. 11 (d) While the knife 51 was being pulled up, the guide pipe 52 was inserted together with the insertion needle 53, but as with the first embodiment, the knife 51 was attached to the subcutaneous tissue 4. The guide pipe 52 may be advanced to the fifth position in the subcutaneous tissue when in the fourth position in FIG. In this case, although the cut is slightly larger, the guide pipe 52 can be reliably inserted into the cut.

Next, the air cylinder 17 pulls out the guide pipe 52 from the skin 45 and stops it with its tip located in the ring-shaped skin contact portion 29a (FIG. 12 (g)). At this time, the air cylinder 18 does not operate, and the follicle retraction unit 53 a keeps the follicle 31 a at the sixth position inside the subcutaneous tissue 46. In this state, the air cylinder 18 pulls up the insertion needle 53 to near the third position and stores it in the body 50 (FIG. 12 (h)). Since the follicle withdrawal portion 53a of the insertion needle 53 forms an obtuse angle with the needle body 53b, it smoothly separates from the follicle 31a. Further, the air cylinder 17 returns the guide pipe 52 to the fifth position and stores it in the body 50. The ring-shaped skin contact portion 29 a of the skin holding portion 29 allows the portion to be planted to be accurately positioned. The epidermal contact portion 29a is transferred to the next portion to be transplanted after transplanting.

Subsequently, while using the pin (not shown), the user of the flocking device rotates the dial 41 and jogs the cartridge 70 while feeling a moderation with the pin (not shown), and the next notch 76 inserts the insertion needle 5. When reaching the locus of 3, stop the dial 4 1 from rotating. Hereinafter, the operations of FIGS. 11 (a) to (e) and FIGS. 12 (f) to (i) are repeated for a desired number of flocks.

The numerical values such as the width and thickness of the scalpel, the inner diameter and thickness of the guide pipe, and the width of the slit described in the first and second embodiments are merely examples and are not limited thereto. Not something.

In the first and second embodiments, the guide pipe is inserted into the subcutaneous tissue together with the insertion needle and the hair root in a state where at least the tip of the insertion needle with the hair root hooked is inserted into the guide pipe. After inserting the guide pipe into the subcutaneous tissue, at least the tip of the insertion needle with the hair root hooked may be inserted into the guide pipe. That is, first open the epidermis with a scalpel and place this scalpel in the subcutaneous tissue At the same time as pulling out the scalpel while leaving it, a guide pipe adjacent to the scalpel is inserted into the subcutaneous tissue from the cut incision. Next, the hair root and at least the tip of the insertion needle are inserted into the guide pipe while the hair root of the hair is hooked by the insertion needle, and the scalpel and the guide pipe or the guide pipe are pulled with the insertion needle and the hair root remaining in the subcutaneous tissue 內. Unplug. Further, the insertion needle is pulled out with the hair root remaining in the subcutaneous tissue. In this hair transplanting method, similarly to the hair transplanting methods described in the first and second embodiments, the hair root can be transplanted into the subcutaneous tissue without breaking the hair root.

As described above, according to the present invention, since the scalpel, the guide pipe, and the insertion needle are separately protruded from the body main body and stored, the following excellent effects are obtained.

(a) If the lengths of the scalpel, guide pipe and insertion needle protruding from the body body are set by a stopper, etc., even if there is no skilled skill, the roots can be evenly distributed at a predetermined depth in the subcutaneous tissue. Can be planted. In addition, if a scalpel, guide pipe and insertion needle are made to enter the subcutaneous tissue with an air cylinder, even if there is no skilled skill, the hair roots can be implanted more efficiently and uniformly at a predetermined depth in the subcutaneous tissue. Can be.

(b) Instead of pushing the hair root into the subcutaneous tissue, while protecting the hair root with a guide pipe, drag the hair root into the subcutaneous tissue with an insertion needle, and the hair root retraction part smoothly separates from the hair root, so enter the subcutaneous tissue. Hair follicles do not shrink, but rather stretch. Thereby, hair having a normal shape is grown.

(c) Unlike a conventional pipe-shaped flocking needle, the epidermis is not cut because a flat scalpel is used and a guide pipe is inserted from an incision made by the scalpel. Immediately after cutting the epidermis with a scalpel, a follicle is inserted, and this follicle closes the cut. From these facts, there is less bleeding due to hair transplantation, and the degree of damage to the subcutaneous tissue is smaller than when a conventional hair transplantation needle is inserted.

(d) By using a cartridge in which a plurality of hairs are arranged in advance, hair can be transplanted almost continuously, and the time for transplanting hair can be greatly reduced. Industrial applicability

The hair transplanting method and the hair transplanting device of the present invention can be used to transplant hairs with hair roots one by one in a short time and uniformly to a necessary part of a body without crushing the roots, without requiring skilled skills. It can be used as a method and an apparatus.
