Description

Needle channel with rotor guide and multi-channel hair transplanter having the same}

The present invention relates to a hair transplant device, and more specifically, to a multi-channel hair transplant device equipped with a plurality of hair transplant needles (transplant needles) in a bundle.

A hair transplant device (transplant device) is a medical device used in a hair treatment method that harvests hair from the hair growth area of the scalp and transplants it to the scalp of another hair loss area (infertile patient).

As a conventional hair transplant machine, for example, the "multi-channel hair transplant machine" of Korean Patent Publication No. 2019-0109321 is a bundle-type hair transplant equipped with a plurality of basting channels consisting of a needle (transplant needle) and a mandrel slidably inserted into the needle. The device was released.

The hair transplantation (hair transplantation) operation according to a conventional multi-channel hair transplanter is schematically shown in Figure 1. First, as shown in Figure 1(a), the hair follicle to be transplanted is inserted into the inner space at the lower end of the needle 1, and the hair transplanter is lowered as shown in Figure 1(b) and the tip of the needle 1 is inserted into the scalp. . At this time, insert the needle (1) into the scalp until the lower end of the nozzle (5) of the hair transplanter touches the scalp. Afterwards, the needle (1) moves upward relative to the nozzle (5) and the mandrel (3) and rises, leaving the hair follicles in the scalp (Figure 1(c)) and lifting the entire hair transplant device to complete the hair transplant operation (Figure 1(c)). 1(d)).

However, according to this conventional hair transplant operation, the needle must be inserted into the scalp to a depth of approximately 7.5 mm to 8.5 mm, but the deeper the insertion depth, the more safety problems may occur for the patient, such as damage to the patient's scalp and bleeding. Additionally, in order to prevent this, if the practitioner inserts the needle at a shallow depth (i.e., at a depth where the lower end of the nozzle 5 does not touch the scalp), the hair transplanter cannot be supported against the scalp, so the hair transplanter moves left and right. Because it shakes, it is difficult to prevent damage to the scalp in this case as well.

Figure 2 is a perspective view of a hair transplant machine (hair transplanter) according to an embodiment, Figure 3 is a cross-sectional view of the hair transplant machine, and Figure 4 is an exploded perspective view.

Referring to the drawings, the hair transplant device of one embodiment consists of a case 10, and a nozzle portion 20 and an upper cap 30 respectively coupled to the lower and upper portions of the case 10. The nozzle unit 20 is located inside the lower cap 50 that is detachably fastened.

Case 10 is a cylindrical member with open top and bottom. Inside the case 10, an hour hand channel bundle (B) in which a plurality of hour hand channels 1200 are combined in a bundle shape is rotatably disposed. The hour hand channel bundle (B) is a multi-channel unit composed of a plurality of hour hand channels, and may be composed of a bundle main body 1100 and a plurality of hour hand channels 1200 arranged at radial equal intervals on the outer peripheral surface thereof.

A channel rotation means is disposed around the outer periphery of the hour hand channel bundle (B) to rotate the hour hand channel bundle by a predetermined angle by one channel. In the illustrated embodiment, the channel rotation means is a cylindrical lifting gear holder 1400 surrounding the outer peripheral surface of the hour channel bundle and a ratchet ( ratchet) may include a support portion 1300.

The ratchet support portion 1300 is formed to protrude inward on the inner surface of the case 10. The lifting gear holder 1400 can slide in the up and down directions. In one embodiment, the hour hand channel bundle may be rotated by a predetermined angle each time the lifting gear holder 1400 performs one raising and lowering operation. For example, the hour hand channel bundle B can be rotated by one hour channel interval by one raising/lowering operation of the lifting gear holder 1400. The specific configuration and operation of the channel rotation means by the ratchet support 1300, the lifting gear holder 1400, etc. are known, for example, in Korean Patent Publication No. 2019-0109321, etc., so detailed descriptions are omitted.

A mandrel locking portion 1700 is disposed on the side of the case 10. The mandrel locking portion 1700 has a function of temporarily preventing the mandrel from moving by hooking the mandrel (1230 in FIG. 7) slidably disposed inside the hour hand channel 1200.

A nozzle unit 20 is fastened to the lower end of the case 10. In the illustrated embodiment, the nozzle unit 20 may be composed of a ring-shaped nozzle unit frame 21 and a nozzle 25 and a central support unit 22 integrally connected to the frame 21 and formed at the lower end and the center, respectively. You can. The nozzle 25 is a through hole through which one basting channel 1200 can pass, and one basting channel 1200 can protrude downward by a predetermined length through the nozzle 25.

The central support portion 22 has a receiving portion that is open upward and is formed in the center of the nozzle portion 20. As shown in Figure 3, the central shaft 1550 is disposed in the longitudinal direction along the central axis of the case 10. In order to fasten the nozzle portion 20 to the case 10, the lower end of the central shaft 1550 is It is at least partially inserted into the receiving portion of the central support portion 22 of the nozzle portion 20. At this time, the frame 21 of the nozzle unit 20 is engaged with the lower end of the case 10.

In one embodiment, the ring-shaped needle length adjustment ring 40 may be detachably fastened to the lower end of the case 10. The needle length adjustment ring 40 is a ring-shaped member with a thread 41 formed on the inner side, and the thread 41 is configured to engage with the thread 15 formed on the outer lower end of the case 10. The needle length adjustment ring 40 is configured to support the lifting gear holder 40 from below. For example, the needle length adjustment ring 40 is disposed to support the lifting gear holder 1400 from below while contacting one or more connecting protrusions 1420 and 1430 protruding from the outer peripheral surface of the lifting gear holder 1400. The needle length adjustment ring 40 can serve as a stopper that determines the stopping position when the lifting gear holder 1400 descends.

Preferably, the needle length adjustment ring 40 may be configured to adjust the height of connection with the case 10. For example, when fastening by engaging the thread 41 of the needle length adjustment ring 40 and the thread 15 of the case 10, the amount of rotation of the needle length adjustment ring 40 is adjusted to adjust the needle length adjustment ring ( The height at which 40) is fastened to the case 10 can be adjusted. In addition, by adjusting the fastening height in this way, the stopping height when the lifting gear holder 1400 is lowered can be adjusted, so that the needle 1220 of the basting channel that engages the lifting gear holder 1400 and descends is connected to the nozzle portion 20. The degree to which the basting channel needle 1220 protrudes downward through the nozzle 25, that is, the protrusion length of the basting channel needle 1220, can be adjusted.

In one embodiment, the needle length adjustment ring 40 may also have a function to ensure that the nozzle frame 21 and the lower end of the case 10 are engaged. For example, the needle length adjustment ring 40 is fastened to surround the nozzle frame 21 and the lower end of the case 10, thereby preventing the lower end of the case 10 from opening and the nozzle frame 21 from coming off. Accordingly, the central support portion 22 of the nozzle portion 20 is supported by being inserted into the central shaft 1550, and the frame 21 of the nozzle portion 20 is supported by the lower end of the case 10 and the needle length adjustment ring 40. By being supported and fixed, the nozzle unit 20 can be more securely and firmly fastened to the case 10.

According to the configuration of the nozzle unit 20 described above, convenience is provided to the operator when loading (mounting) hair follicles on the needle 1220 of each basting channel 1200. In this regard, Figure 5 is a view showing the lower area of the hair transplant device with the lower cap 50 removed. Referring to Figure 5, most areas of the nozzle portion 20 except for the nozzle 25 and the center support portion 22 are open downward, so that all needles 1220 of each basting channel 1200 of the basting channel bundle are It is exposed. Therefore, in this state, the operator can attach a hair follicle to each needle 1220, so the hair follicle loading operation can be performed much more simply and quickly compared to the conventional structure in which the nozzle 20 had to be removed to load the hair follicle.

Referring again to FIGS. 2 to 4, the hair transplanter includes a push bar 1530 that pushes one basting channel 1200 of the basting channel bundle B in a downward direction. The push bar 1530 is disposed between the upper part of the basting channel bundle (B) and the upper cap 30 within the case 10, and at this time, the push bar 1530 is moved to the upper part by an elastic member such as a spring 1540. It is elastically coupled to the cap 30. The push bar 1530 and the nozzle 25 of the nozzle unit 20 are aligned and positioned in a straight line. Therefore, when the push bar 1530 pushes the hour hand channel 1200 downward, the needle 1220 of the pushed hour hand channel 1200 may protrude by a predetermined length through the nozzle 25.

Figure 6 is a diagram for explaining an hour hand channel bundle (B) according to an embodiment. Referring to Figure 6, the basting channel bundle (B) consists of a bundle main body 1100 and a plurality of basting channels 1200 each coupled to the outer peripheral surface of the bundle main body 1100 so as to be slidable in the up and down directions.

In one embodiment, the bundle body portion 1100 may be composed of a cylindrical channel coupling portion 1110 and a head portion 1120 formed on the channel coupling portion 1110. The channel coupling portion 1110 and the head portion 1120 may be formed as one piece, or may be manufactured separately and combined. The channel coupling portion 1110 and the head portion 1120 have vertical through holes formed inside them, and therefore the central shaft 1550 penetrates the bundle body portion 1100 as shown in Figure 3 or Figure 4. can be placed.

A plurality of slide rails 1115 are formed on the outer peripheral surface of the channel coupling portion 1110 at radial equal intervals based on the central axis of the channel coupling portion 1110. In one embodiment, the slide rail 1115 is long and engraved in the vertical and longitudinal direction, and each hour hand channel 1200 is coupled to each slide rail 1115 by being slidably fitted in the vertical direction.

The head portion 1120 has a larger diameter than the diameter of the channel coupling portion 1110 and thus serves as a stopper to prevent the hour hand channels 1200 from rising any further. As shown in Figure 4, a spring 1520 is interposed between the head portion 1120 and the upper cap 30, and the spring 1520 can elastically support the basting channel bundle B in a downward direction.

Meanwhile, a protective cap 60 for protecting the needles 1220 of the hour hand channel 1200 may be detachably fastened to the lower part of the hour hand channel bundle (B). When attaching the basting channel bundle (B) to the hair transplant machine, remove the protective cap (60) and insert it into the case (10) to install it (see Figure 3 or 4), and replace or exchange the basting channel bundle (B). When removed from the case 10, the needle 1220 can be protected by fastening the protective cap 60 to the basting channel bundle (B).

Figures 7 and 8 are diagrams showing the basting channel 1200 according to an embodiment. Figure 7(a) is a perspective view of the basting channel 1200, Figure 7(b) is a cross-sectional view, and Figure 8 is an exploded perspective view.

Referring to Figures 7 and 8, the basting channel 1200 includes a body portion 1210 having a tubular inner space in the vertical direction, a needle 1220 coupled to the lower portion of the body portion 1210, and the tube. It may be composed of a mandrel 1230 that is slidably disposed in the inner space of the shape.

The tubular internal space of the body portion 1210 may be comprised of an upper first diameter portion 1210a with a relatively large diameter and a lower second diameter portion 1210b with a relatively small diameter. The lower second diameter portion 1210b has a diameter large enough for the mandrel 1230 to pass through, and the upper first diameter portion 1210a accommodates the spring 1241 fitted around the mandrel 1230. It has a diameter large enough to do so. The hair root transplant needle 1220 is inserted and coupled to the body portion 1210 through the open lower end of the second diameter portion 1210b of the body portion 1210. The needle 1220 has a hollow center, that is, a cylindrical shape with a through hole formed along the longitudinal direction, and the through hole of the needle 1220 communicates with the internal space of the body portion 1210.

Figure 9 shows the structure of the lower end of the needle 1220 according to one embodiment. Figure 9(a) is a view when looking toward the central axis from the radial outside of the basting channel bundle (B), and Figure 9(b) is a cross-sectional view seen from the side.

As can be seen in the drawing, a slot hole 1221 that is open to the outside is formed on the lower side of the needle 1220 so that hair follicles can be easily inserted. The mandrel 1230 is inserted into the inner space of the needle 1220, and the lower end of the mandrel 1230 is positioned below the top of the slot hole 1221 and does not protrude below the bottom end of the needle 1220. This slot hole 1221 is formed in a direction facing radially outward of the basting channel bundle (B), thus providing convenience for the operator in mounting hair follicles.

The body portion 1210 includes a side protrusion 1213 formed along one side in the vertical direction. The side protrusion 1213 protrudes in a direction toward the channel coupling portion 1110, that is, in a radial inward direction, and the protrusion shape of the side protrusion 1213 is shaped like a groove of the slide rail 1115 of the channel coupling portion 1110. It is configured to engage with. Accordingly, the side protrusion 1213 of the body portion 1210 is fitted and engaged with the slide rail 1115 of the channel coupling portion 1110, so that the hour hand channel 1200 can slide in the up and down direction along the slide rail 1115.

Referring again to FIGS. 7 and 8, the basting channel 1200 extends from the body 1210 in a direction opposite to the side protrusion 1213 of the body 1210, that is, in a radially outward direction of the basting channel bundle B. It includes an extended catching protrusion 1211. The locking protrusion 1211 includes a slot 1215 formed in an upward and downward direction, a protrusion 1217 extending from the surface of the locking protrusion 1211 to protrude further in a radial outward direction, and a lower end of the locking protrusion 1211, and is formed in one direction. It includes a tooth-shaped ratchet gear 1212 having a large inclination angle.

The slot 1215 is formed in the longitudinal direction (up and down direction) of the body portion 1210 and has a shape that is open toward one side of the body portion 1210. For example, the slot 1215 is formed in the vertical direction on the radially outward surface of the locking protrusion 1211 and communicates with the tubular inner space of the body portion 1210. A mandrel 1230 is disposed in the tubular inner space, and a lever 1231 is coupled to the top of the mandrel 1230. The lever 1231 is guided by the slot 1215 and can slide in the up and down directions. A spring 1241 is fitted around the mandrel 1230. The upper end of the spring 1241 is supported on the lower surface of the lever 1231, and the lower end of the spring 1241 is a step between the first diameter portion 1210a and the second diameter portion 1210b in the body portion 1210. is supported by

The upper end of the slot 1215 is open, and the upper stopper 1250 can be fitted and coupled to the open upper end. The upper stopper 1250 serves as a stopper to prevent the lever 1231 from moving upward any further. As shown in Figure 6, the upper surface of the upper stopper 1250 has a surface inclined in one direction so that the basting channel bundle (B) can rotate smoothly. That is, so that the rotation of the basting channel bundle (B) is not hindered by the push bar 1530 in contact with the upper surface of the upper stopper 1250, the surface 1251 of the upper stopper 1250 is positioned in the rotation direction of the basting channel bundle. It is formed as an inclined surface inclined by a predetermined inclination angle (1253).

The body portion 1210 of the hour hand channel 1200 further includes a locking groove 1219. The locking groove 1219 is formed below the locking protrusion 1211 on the radially outward facing surface of the body portion 1210. The locking groove 1219 can accommodate the latch 1910 of the hour hand channel locking portion 1900.

In one embodiment, the body portion 1210 may further include a rotor guide 1270 extending downward. The rotor guide 1270 extends downward from the lower end of the body portion 1210 to surround at least a portion of the outer peripheral surface of the needle 1220. For example, in the embodiment shown in FIGS. 7 and 8, the rotor guide 1270 surrounds approximately half of the entire circumference (i.e., 360 degrees) of the outer peripheral surface of the needle 1220 (i.e., 180 degrees). It can be configured. However, this is illustrative and, for example, in alternative embodiments the rotor guide 1270 may be configured to surround the needle 1220 between 90 and 270 degrees around the needle 1220.

In addition, for the length of the rotor guide 1270 extending from the lower end of the body portion 1210, the needle 1220 of the basting channel 1200 is connected to the nozzle 25 of the nozzle portion for hair transplantation, as shown in FIG. It is preferable that the lower end of the rotor guide 1270 protrudes lower than the lower end of the nozzle 25 and is exposed to the outside while penetrating the through hole.

Meanwhile, as shown in Figures 3 and 4, the hair transplanter includes a push bar 1530 that pushes one basting channel 1200 of the basting channel bundle B in a downward direction. The push bar 1530 is elastically coupled to the upper cap 30 through an elastic member such as a spring 1540, and is arranged to press one basting channel 1200 of the basting channel bundle B from top to bottom. . The push bar 1530 and the nozzle 21 are aligned and arranged on the same vertical line, so when the push bar 1530 pushes the basting channel 1200 downward, the needle 1220 of the pushed basting channel 1200 ) may protrude by a predetermined length through the nozzle 25.

FIG. 10 schematically shows an exemplary configuration of the nozzle unit 20 according to an embodiment. FIG. 10(a) is a view of the nozzle unit 20 from bottom to top, and FIG. 10(b) is a view. A portion of 10(a) is enlarged to show that the needle 1220 of the hour hand channel 1200 and the rotor guide 1270 are penetrating the nozzle 25.

Referring to Figure 10(a), the nozzle 25 is provided with a through hole 26 for the needle 1220 to pass through. More preferably, the through hole 26 is a hole 26 that partially surrounds the needle 1220 and the needle 1220. The rotor guide 1270 has a shape that can penetrate. For example, in the embodiment of Figure 10(a), the through hole 26 has a small diameter area 26a having a first radius from the center C of the through hole 26 and a smaller diameter area 26a having a first radius from the center C. It may be composed of a large diameter area 26b having a large second radius. The small diameter area 26a is an area through which the needle 1220 that is not surrounded by the rotor guide 1270 penetrates, and the large diameter area 26b is an area through which the rotor guide 1270 surrounding the needle 1220 penetrates. You can.

In one embodiment, the nozzle 25 may further include a slot 27 extending from the through hole 26 to the side of the nozzle 25. The slot 27 may be formed to be aligned in the same direction as the slot hole 1221 of the needle 1220.

Referring to Figure 10(b), the inner circumference (inner peripheral surface) of the through hole 26 of the nozzle 25 defines the first inner peripheral surface 261, which defines the perimeter of the small diameter area 26a, and the perimeter of the large diameter area. It is composed of a second inner circumferential surface 262, and a step portion 263 connecting the first inner circumferential surface 261 and the second inner circumferential surface 262. It will be understood that the length of the step portion 263 corresponds to the difference between the first radius of the small diameter region 26a and the second radius of the large diameter region 26b.

In one embodiment, the second radius of the large diameter region 26b may be equal to or slightly greater than the distance from the central axis of the needle 1220 to the radial first peripheral surface 1271 of the rotor guide 1270. Therefore, as shown in FIG. 10(b), the rotor guide 1270 penetrates while the first outer peripheral surface 1271 of the rotor guide 1270 is in close contact with the second inner peripheral surface 262 of the through hole 26. It moves by sliding relative to the sphere 26.

Additionally, in one embodiment, the rotor guide 1270 has a second peripheral surface 1272 that extends in a radial direction (i.e., in the embodiment shown, the normal vector direction of the surface has a direction perpendicular to the radial direction). The rotor guide 1270 may slide and move relative to the through hole 26 while the second outer peripheral surface 1272 is at least partially in contact with the step portion 263 of the through hole 26. Therefore, the first outer peripheral surface 1271 and the second outer peripheral surface 1272 of the rotor guide 1270 are supported and slid by the second inner peripheral surface 262 and the step portion 263 of the through hole 26, respectively, so that the needle ( 1220) and the rotor guide 1270 can move forward and backward without shaking left or right with respect to the transplanter main body.

Figure 11 shows a mandrel locking portion 1700 according to an embodiment, where Figure 11(a) schematically shows a view from the side and Figure 11(b) shows a view from the front. The mandrel locking portion 1700 is disposed on the radial outer side of the hour hand channel pushed downward by the push bar 1530. In the illustrated embodiment, the mandrel locking portion 1700 is installed on one side of the case 10. The mandrel locking portion 1700 functions to temporarily stop the movement of the mandrel 1230 in the hour hand channel 1200 while the hour hand channel 1200 is pushed downward by the push bar 1530 and then rises again. do.

Referring to the drawing, the mandrel locking portion 1700 includes a latch 1710, a latch receiving portion 1720 that accommodates the latch 1710, and an elastic member interposed between the latch 1710 and the latch receiving portion 1720 ( 1730).

For example, the latch receiving portion 1720 may be fixed to one side of the case 10 by bolting through a bolt groove in the extension area 1723 on both left and right sides. Here, the bolt groove of the latch receiving portion 1720 may be rectangular so that the position of the latch 1710 can be adjusted. The position of the latch determines the length of the mandrel 1230 that protrudes out of the nozzle 25 during the hair follicle insertion operation, thereby affecting the depth of the hair follicles to be transplanted. The latch receiving portion 1720 has a space inside which the latch 1710 can fit, and an elastic member 1730 such as a spring is interposed in this space. Accordingly, the latch 1710 is disposed within a distance that interferes with the vertical movement of the lever 1231 and is configured to elastically retract in a radial outward direction of the hour hand channel bundle (B).

When no force is applied to the clasp 1710, the clasp 1710 protrudes from the clasp receiving portion 1720 (in the radial inner direction of the basting channel bundle (B)) so that when the lever 1231 moves up and down. It comes into contact with the lever 1231. At this time, as shown in FIG. 11(a), the upper side of the contact surface of the latch 1710 in contact with the lever 1231 is inclined upward, and the lower lever contact surface 1711 is formed to be approximately horizontal. Therefore, when the lever 1231 descends downward from the top of the latch 1710, the lever 1231 may descend while pushing the latch 1710 toward the latch receiving portion 1720, but the lever 1231 moves toward the latch 1710. When rising from the bottom to the top, the upper surface of the lever 1231 is caught in contact with the lever contact surface 1711 of the latch 1710, so the lever 1231 cannot rise any further.

Meanwhile, a protrusion 1217 is formed on the side of the slot 1215 of the hour hand channel 1200, protruding radially outward from the hour hand channel bundle (B). This protrusion 1217 is the same as the lever 1231 or protrudes more outward than the lever 1231 in the radial outward direction. In addition, the left and right widths of the latch 1710 are set to interfere with the vertical movement of the protrusion 1217 as well as the lever 1231, and the latch 1710 contacts the protrusion 1217 as shown in the drawing. ) The upper side of the contact surface is inclined upward and the lower protrusion contact surface 1713 is also formed to be inclined downward. Therefore, in either case where the basting channel 1200 rises upward from the bottom of the clasp 1710 or descends downward from the top, the protrusion 1217 pushes the clasp 1710 toward the clasp receiving portion 1720 and the basting channel 1200 Can rise/descend.

The locking and unlocking operations of the mandrel 1230 by the mandrel locking portion 1700 having the above-described configuration will be described with reference to FIG. 12 .

Figure 12(a) shows the state before the hour hand channel 1200 attached to the hour hand channel bundle (B) is lowered. In this state, both the lever 1231 and the protrusion 1217 of the hour hand channel 1200 are located above the latch 1710 of the mandrel locking portion 1700.

When the push bar 1530 pushes the hour hand channel 1200 downward, the hour hand channel 1200 descends. When the basting channel 1200 descends, the protrusion 1217 and the lever 1231 contact the inclined surface of the clasp 1710, so the clasp 1710 is pushed toward the clasp receiving portion 1720 and the basting channel 1200 and The lever 1231 can be lowered.

As shown in Figure 12(b), when the lever 1231 is lowered lower than the latch 1710, the lever 1231 does not go down but rises upward by the spring 1241, but the lever 1231 As the upper surface of comes into contact with the lever contact surface 1711 of the latch 1710, the lever 1231 is caught by the latch 1710.

Afterwards, as shown in FIG. 12(c), when the hour hand channel 1200 rises, the lever 1231 and the mandrel 1230 integrally coupled thereto rise because the lever 1231 is caught on the latch 1710. can not do.

When the hour hand channel 1200 rises further, the protrusion 1217 contacts the clasp 1710 and pushes the clasp 1710 toward the clasp receiving portion 1720, as shown in FIG. 12(d). Therefore, as the latch 1710 retreats toward the latch receiving portion 1720, the latch on the lever 1231 is released, and the lever 1231 and the mandrel 1230 rise due to the elastic force of the spring 1241. You can return to the status of 12(a).

Figure 13 is a diagram illustrating the forward and backward movements of the basting channel 1200 for hair transplantation according to an embodiment.

Figure 13(a) shows the state before inserting the needle 1220 of the basting channel 1200 for hair transplantation into the hair transplantation position on the scalp. In this state, hair follicles for transplantation are accommodated inside the needle 1220, and a part of the needle 1220 and the rotor guide 1270 protrudes below the lower end 25a of the nozzle 25. Specifically, the mandrel 1230 in the needle 1220 protrudes downward by a first distance d1 from the lower end 25a of the nozzle 25, and the lower end 1270a of the rotor guide 1270 protrudes downward from the lower end 25a of the nozzle 25. ) protrudes downward by a second distance d2 from the lower end 25a. At this time, it is preferable that the second distance d2 is larger than the first distance d1. In addition, the second distance d2 is preferably smaller than the third distance d3 from the lower end of the nozzle 25 to the point where the tapered shape of the tip of the needle 1220 begins.

In this state, for example, the operator manually or automatically moves the hair transplanter downwards using an automatic hair transplant device to insert the needle 1220 into the scalp. When the lower end 1270a of the rotor guide 1270 touches the scalp, the needle 1220 no longer enters, so the rotor guide 1270 serves to determine the insertion depth of the needle 1220. Meanwhile, in the state shown in FIG. 13(b), the hair follicles in the needle 1220 may not be completely inserted into the scalp.

Afterwards, the needle 1220 and the rotor guide 1270 begin to move upward relative to the main body of the hair transplanter. For example, as shown in Figure 12(C), the hour hand channel 1200 rises, but since the lever 1231 is caught on the latch 1710, the lever 1231 and the mandrel 1230 integrally coupled thereto do not rise. As a result, the body portion 1210 (integrated with the rotor guide 1270) and the needle 1220 of the hour hand channel 1200 rise. However, since the operator is pressing the hair transplanter body toward the scalp in the state shown in Figure 13(b), the same effect as the hair transplanter body descending relative to the needle 1220 and the rotor guide 1270 occurs. That is, the state of FIG. 13(b) changes to the state of FIG. 13(c), where the needle 1220 and the rotor guide 1270 are stationary with respect to the scalp, and the nozzle 25 and the mandrel 1230 are The mosquito body descends until the lower end (25a) of the nozzle (25) touches the scalp.

As shown in FIG. 13(c), when the lower end 25a of the nozzle 25 touches the scalp, the mandrel 1230, which protrudes further downward by a first distance d1 than the lower end 25a, moves the hair follicle further downward. By pushing it in, the hair follicles can be seated inside the scalp.

And, as shown in Figures 12(c) and 12(d), the mandrel 1230 is stationary while the needle 1220 rises to a certain height, while the body portion 1210 excluding the mandrel 1230 and the needle ( The remaining components of the basting channel 1200, such as 1220) and the rotor guide 1270, continue to rise upward. That is, as shown in Figures 13(c) and 13(d), after the lower end 25a of the nozzle touches the scalp, a relative upward movement of the needle 1220 and the rotor guide 1270 occurs with respect to the scalp (Figure 13 ( d)), After the needle 1220 rises to a certain height, the mandrel 1230 also rises. At this time, the operator or the automatic hair transplant device may keep the body of the hair transplant device in close contact with the scalp so that the lower part of the nozzle 25a is in contact with the scalp until the needle 1220 rises and leaves the scalp. Alternatively, the practitioner or the automatic hair transplant device may keep the hair transplanter body in close contact with the scalp so that the nozzle lower part 25a is in contact with the scalp until the mandrel 1230 rises and leaves the scalp.

In this way, one hair transplant operation can be completed by raising the hair transplanter body upward after the needle 1220 and/or the mandrel 1230 separates from the scalp and rises upward. And in one embodiment, when the needle 1220 and the mandrel 1230 rise to a predetermined height, the basting channel bundle B is positioned at a predetermined angle by a structure such as the ratchet support 1300 and the lifting gear holder 1400. Rotating, the push bar 1530 pushes the basting channel adjacent to the basting channel just used for the hair transplant operation, so that the needle 1220 passes through the nozzle 25 and protrudes downward, as shown in FIG. 13(a). This prepares for the second transplanting operation.

As can be seen from the comparison of the hair transplant operation according to the prior art in Figure 1 and the hair transplant operation according to an embodiment of the present invention in Figure 13, in the present invention, the needle 1220 is inserted into the scalp at a relatively shallow depth and then the nozzle is inserted. (25) and the central axis 1230, the hair transplanter main body performs an additional motion of descending toward the scalp, thereby stably transplanting hair follicles into the scalp, reducing damage or bleeding to the patient's scalp, and reducing the patient's or operator's resistance to the hair transplant procedure. can be alleviated.

As described above, various modifications and variations can be made by those skilled in the art in the field to which the present invention pertains from the description of the above-described specification. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the claims and equivalents thereof as well as the claims described later.
