BACKGROUND
1. Field

The present invention relates to a hair identifying device and an apparatus for automatically separating hair follicles including the same.

2. Description of the Related Art

As the human body ages, hair loss (alopecia) may be experienced, wherein hair falls out from the scalp, for various reasons such as physical changes, genetic effects, hormone effects, eating habits, stress, irregular lifestyles, and environmental factors. Alopecia patients account for about 20% to 30% of the world's population, and the percentage continues to increase.

Especially in modern society where great importance is attached to beauty, the quantity of hair has a lot of influence on appearance. In general, when hair loss occurs, self-confidence decreases and may be the cause of stress such as appearing older than the person's age. Thus, according to the stage of hair loss, various types of hair loss management methods have been proposed, such as scalp management, hair loss shampoo, drug treatment, and self-hair transplants.

In self-hair transplants, since follicles without hair loss genes are taken from the back of the head, hair loss is permanently prevented and the effect is visible to the naked eye within a short period of time. Recently, hair transplants for young people have also been on the rise for beauty purposes, to look younger and boost self-confidence or to organize the forehead hairline.

Such self-hair transplants can be divided into an incisional hair transplant method that removes a portion of the patient's own scalp and a non-incisional hair transplant method that extracts only follicles one by one.

In the incisional hair transplants, several follicle separating professionals separate the follicles one by one after cutting and removing a portion of the scalp, which takes a long time and the speed of separating hair follicles varies greatly depending on the skill of the worker. In addition, there are problems such as irregular separation of follicles, varying quality of follicle separation even if a same worker does the job depending on the worker's condition that day, long operation time which makes the patient feels uncomfortable and increases operation costs due to the labor costs of the follicle separating professional.

In the non-incisional hair transplants, follicles are extracted and then the connective tissue of the extracted follicles need cutting and trimming so that they can be easily planted on the scalp. Accordingly, there are problems where the fatigue level of both doctor and patient increases, and as the concentration of the doctor decreases due to the accumulation of fatigue, this causes damage to healthy follicles such as cutting the same when collecting the follicles, which lowers engraftment rate.

To cope with these problems, for example, in Korean Patent No. 10-1800365, an apparatus for automatically separating follicles in an incisional hair transplant or in a non-incisional hair transplant.

There is a case in which follicles are classified by the number of hairs after separating follicles from a scalp in the incisional hair transplant or in the non-incisional hair transplant. Conventionally, this type of work has been done by a worker with naked eyes. However, because the follicle parts are not transparent, it is hard to identify the hairs so that the follicles may be damaged while being cut.

BEST MODE(S) FOR CARRYING OUT THE INVENTION

Exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

In this specification, a skin tissue refers to a tissue cut out from a certain part of a back of a head of an alopecic patient where there are no hair loss genes.

In this specification, a connective tissue refers to a tissue surrounding and supporting units of follicles in the skin tissue.

FIG. 1 is a functional block diagram of an automatic hair-follicle separating apparatus 1 according to some embodiments of the present invention. FIG. 2 is a functional block diagram of a follicle separating unit 10 according to some embodiments of the present invention.

As shown in FIG. 1, the automatic hair-follicle separating apparatus 1 includes a follicle separating unit 10 and a follicle separation control unit 20.

The follicle separating unit 10 collects various information and data on an image obtained by scanning the scalp cut from a back of a head of an alopecic patient, and after separating units of follicles from a connective tissue without damaging the same, follicles are selected and stored based on the number of hairs formed in each of the separated units of follicles.

As shown in FIG. 2, the follicle separating unit 10 includes an incisional follicle separating unit 100, a non-incisional follicle separating unit 200, and a hair identifying device 300.

The incisional follicle separating unit 100 is configured to scan the scalp cut from the back of the head of the alopecic patient to separate each unit of follicles from the connective tissue formed in the skin tissue, and to select follicles based on the number of hairs included in a unit of follicles.

The hair identifying device 300 is used, for example, to identify hairs in the final process of the incisional follicle separating unit 100 or the non-incisional follicle separating unit 200.

FIG. 3 is a functional block diagram of a hair identifying device 300 according to some embodiments of the present invention. FIG. 4 is a schematic diagram showing a work of cutting a follicle with a blade by a worker. FIG. 5 is a schematic diagram showing a process of determining the number of hairs of a double follicle. FIG. 6 is a schematic diagram showing a process of determining the number of hairs of a triple follicle.

As shown in FIG. 3, the hair identifying device 300 includes an image acquiring unit 310, an image processing unit 320, a hair count determining unit 330, a control unit 340, and a display unit 350.

The hair identifying device 300 identifies the number of hairs in each follicle that is obtained by removing skin tissues surrounding the follicle on a follicle separating plate.

That is, the hair identifying device 300 classifies the follicles into single follicles with one hair in one follicle, double follicles with two hairs in one follicle, and triple follicles with three hairs in one follicle, quadruple follicles with four hairs in one follicle, and the like.

In some embodiments of the present invention, the image acquiring unit 310 uses a laser photosensor to place a follicle at a focal plane and records an image of the follicle with light passing through or reflected from the follicle.

In some embodiments of the present invention, the image acquiring unit 310 records a hair 22 to a follicle 24 with a photosensor array to acquire an image of the hair 22 and the follicle 24.

In some embodiments of the present invention, the image acquiring unit 310 uses laser light as a light source, aligns a focal point of the hair 22 with a focal point of a sensing pinhole with the light from the point source, and measures a hair region with a portion other than the focal plane not showing in the image. The image acquiring unit 310 can use a confocal laser scanning microscope.

Although it is described that the image acquiring unit 310 uses a laser light source in the above example, the present invention is not limited to this scheme, but various recording means can be used such as an ultrasonic sensor array, an infrared sensor array, and the like.

The image acquiring unit 310 can measure a minute change of reflected light from a single hair using the confocal laser scanning microscope or visualize the internal structure by scanning the area from the hair 22 to the follicle 24. A two-dimensional image can be reconstructed as a three-dimensional image with the help of a computer software program.

In some embodiments of the present invention, the image acquiring unit 310 includes a light emitting unit for emitting light of a predetermined wavelength towards a follicle and a light receiving unit for receiving reflected light from the follicle and converts the received light into an electrical signal.

In some embodiments of the present invention, the light emitting unit includes a light-emitting element array having a plurality of light-emitting elements arranged in an arrayed manner and a light-receiving element array having a plurality of light-receiving elements respectively corresponding to the plurality of light-emitting elements.

In some embodiments of the present invention, the image processing unit 320 converts the acquired image of the hair 22 and the follicle 24 into a grayscale image, removes a noise signal from the grayscale image, passes the noise-free image through a sharpening filter, and emphasizes edges of the image.

After emphasizing the edges of the image, the image processing unit 320 performs a contour detection process or an edge detection process to extract the edge of the image.

The image processing unit 320 processes the image of the hair 22 and the follicle 24 as black (pixel value 0) and the background other than the image of the hair 22 and the follicle 24 as while (pixel value 255).

The hair count determining unit 330 can calculate a position of each hair in a follicle and a distance between hairs from the image obtained by the image processing.

Although the image processing by the image processing unit 320 is describe above to calculate the position of each hair and the distance between hairs as an example, the present invention is not limited to this scheme, but various other methods can be used to calculate the position of each hair and the distance between hairs.

For example, the position of each hair and the distance between hairs can be directly calculated through machine learning from the image before the image processing or after the image processing.

In addition, in a case in which a hair is cut in the middle, the hair count determining unit 330 can set the minimum length of the hair to eliminate the cut hair from the determination of the hair count. To this end, the hair count determining unit 330 can determine a cut hair from the image of the hair and the follicle obtained through the image processing, exclude the cut hair from the hair count, and set a position between the cut hair and a normal hair as the cutting position.

Referring to FIG. 5, a process of identifying the number of hairs by the hair count determining unit 330 for a double follicle having two hairs in one follicle is described below.

The hair count determining unit 330 sets an image of extracted edges as an interest area 30 and spatially divides the interest area 30 to build pixel coordinates.

The hair count determining unit 330 draws a horizontal imaginary line in the horizontal direction on black pixels of the interest area 30 and sets black pixels included in the horizontal imaginary line as feature points.

The hair count determining unit 330 obtains a width between hairs by calculating a distance between pixel coordinates of the feature points. The width represents a distance between hairs in the horizontal direction.

The hair count determining unit 330 draws a plurality of horizontal imaginary lines 33a, 33b, 33c, 33d, and 33e in the horizontal direction on the black pixels at a plurality of positions of the edges representing each hair 22 and sets the black pixels include in each of the plurality of horizontal imaginary lines 33a, 33b, 33c, 33d, and 33e as a plurality of feature points 31a and 32a, 31b and 32b, 31c and 32c, 31d and 32d, and 31e and 32e.

The hair count determining unit 330 can calculate distances between hairs at a plurality of positions of the hair 22 from the distances between pixel coordinates of the feature points 31a and 32a, 31b and 32b, 31c and 32c, 31d and 32d, and 31e and 32e.

The hair count determining unit 330 determines whether the calculated minimum distance is within a predetermined error range of a reference minimum distance, and if the minimum distance is within the error range, determines the follicle as a double follicle including two hairs because the hairs form a ‘V’ shape. The reason why the hair count determining unit 330 determines whether the calculated minimum distance is within a predetermined error range of reference minimum distance is to figure out the distance between two hairs gradually decreases as the two hairs meet together at the follicle in the end.

When two hairs are identified in one follicle, the hair count determining unit 330 extracts a horizontal imaginary line 33a having the maximum value among the distances between the two hairs, calculates a midpoint 34 that is the center of the horizontal imaginary line 33a, and sets the pixel coordinates of the midpoint 34 as a cut position for descending a blade.

The hair count determining unit 330 compares the distance between two hairs to determine whether the distance decreases from one side of the interest area 30 to the other side of the interest area 30 or not, and if it is determined that the distance does not gradually decrease, the distance decreases so that the minimum distance falls within the error range but increases again, or the minimum distance does not fall within the predetermined error range of the reference minimum distance, classifies it as a follicle inappropriate to separate hairs because of tangled hairs, crossed hairs, cut hairs, and the like.

The control unit 340 outputs the follicle inappropriate to separate hairs, position coordinates of hairs classified by the hair count determining unit 330, the distance between hairs, the pixel coordinates of the midpoint 34 included in a two-dimensional or three-dimensional image to the display unit 350.

Referring to FIG. 6, a process of identifying the number of hairs by the hair count determining unit 330 for a triple follicle having three hairs in one follicle is described below.

The hair count determining unit 330 sets an image of extracted edges as an interest area 40 and spatially divides the interest area 40 to build pixel coordinates.

The hair count determining unit 330 draws a horizontal imaginary line in the horizontal direction on black pixels of the interest area 40 and sets black pixels included in the horizontal imaginary line as feature points. In this case, three feature points are formed on a single horizontal imaginary line.

The hair count determining unit 330 draws a plurality of horizontal imaginary lines 33a, 33b, 33c, 33d, and 33e in the horizontal direction on the black pixels at a plurality of positions of the edges representing each hair 22 and sets the black pixels include in each of the plurality of horizontal imaginary lines 41a, 41b, and 41c, 42a, 42b, and 42c, 43a, 43b, and 43c, and 44a, 44b, and 44c.

The hair count determining unit 330 can now calculate the distance between hairs at a plurality of positions of the hair 22 from the distance between pixel coordinates of the features points.

When three features points are formed on a single horizontal imaginary line, the hair count determining unit 330 calculates a first distance between the pixel coordinates of the feature points 41a and 41b, a first distance between the pixel coordinates of the feature points 42a and 42b, and a first distance between the pixel coordinates of the feature points 43a and 43b, and a first distance between the pixel coordinates of the feature points 44a and 44b, and calculates a second distance between the pixel coordinates of the feature points 41b and 41c, a second distance between the pixel coordinates of the feature points 42b and 42c, and a second distance between the pixel coordinates of the feature points 43b and 43c, and a second distance between the pixel coordinates of the feature points 44b and 44c.

The hair count determining unit 330 compares the plurality of first distances to determine whether the distance decreases from one side of the interest area 40 to the other side of the interest area 40 or not, and if the distance gradually decreases, calculates a first minimum distance.

The hair count determining unit 330 compares the plurality of second distances to determine whether the distance decreases from one side of the interest area 40 to the other side of the interest area 40 or not, and if the distance gradually decreases, calculates a second minimum distance.

The hair count determining unit 330 determines whether the calculated first minimum distance and the second minimum distance are within a predetermined error range of reference minimum distance, and if the first minimum distance and the second minimum distance are within the error range, determines the follicle as a triple follicle including three hairs because the hairs form a ‘W’ shape.

When three hairs are identified in one follicle, the hair count determining unit 330 calculates a midpoint 45 that is the center of the distance between the pixel coordinates of the feature points 41a and 41b, sets first pixel coordinates of the midpoint 45 as a cut position for descending a blade, calculates a midpoint 46 that is the center of the pixel coordinates of the feature points 42a and 42b, and sets second pixel coordinates of the midpoint 46 as a cut position for descending a blade.

Upon the control unit 340 receiving the first pixel coordinates of the midpoint 45 and the second pixel coordinates of the midpoint 46 from the hair count determining unit 330 and a control command to obtain a single follicle and a double follicle from an input unit (not shown), sends one of the first pixel coordinates and the second pixel coordinates to a control module (not shown) of a cutting device (not shown).

Then, a blade descends to one of the first pixel coordinates and the second pixel coordinates to divide the follicle into a single follicle and a double follicle.

Upon the control unit 340 receiving the first pixel coordinates of the midpoint 45 and the second pixel coordinates of the midpoint 46 from the hair count determining unit 330 and a control command to obtain three single follicles from the input unit, sends both the first pixel coordinates and the second pixel coordinates to the control module of the cutting device (not shown).

Then, the blade descends to both the first pixel coordinates and the second pixel coordinates to divide the follicle into three single follicles.

As shown in FIG. 7, the incisional follicle separating unit 100 includes a conveyor belt unit 110, a scalp data analyzing unit 120, a first cutting unit 130, a second cutting unit 140 and a follicle selective unit 150.

The conveyor belt 110 is a conveyor belt formed horizontally from a leading end to a trailing end and configured to rotate in a single linear direction by a rotation of a driving motor controlled by the follicle separation control unit 20 to transport the connective tissue including a unit of follicles positioned on one side above the conveyor belt 110.

The conveyor belt 110 is configured to have a locking projection formed protruding to the left and right peripheral ends of a belt rail such that an antibacterial cutting plate 111 (see FIG. 18) is fitted and coupled along the central periphery.

The antibacterial cutting plate 111 directly supports the skin tissue including the follicles and transports the skin tissue according to the rotation of the conveyor belt 110.

As shown in FIG. 18, the antibacterial cutting plate 111 is sterilized by a belt having a repetitive sawtooth shape pattern with a slope heading upward in a forward direction and formed of an antibacterial, corrosion-resistant and elastic material (for example, silicon).

The antibacterial cutting plate 111 prevents contamination and damage of follicles by blocking infection caused by exposure to bacteria through the side of the connective tissue in direct contact cut from a patient.

According to some embodiments of the present invention, the antibacterial cutting plate 111 is composed of disposable consumables that are discarded when follicle separation is completed in consideration of hygiene issues.

The scalp data analyzing unit 120 scans the cut skin tissue to measure the average density of hairs formed in the scalp, measures the hardness of the skin tissue, and collects dataficated information.

As shown in FIG. 8, the scalp data analyzing unit 120 includes a scanning unit 121, a monitor unit 122, and a skin hardness measuring unit 123.

The scanning unit 121 is positioned in the vertical direction on an upper side of a conveyor belt unit, and is configured to include moving up and down along a scanning guide rail formed in an up-and-down direction, scanning a cut skin tissue as a whole to determine a follicle distribution, and measuring an interval between follicles to determine an average density of the hair in the skin tissue.

According to some embodiments of the present invention, the scanning unit 121 scans the whole skin tissue by moving up and down in an up-and-down direction according to the size and length of the cut skin tissue and adjusting the focal length, and it is possible to zoom in/out of the portion to be scanned to provide the monitor unit 122 with a partially enlarged and reduced screen.

The monitor unit 122 enlarges and displays the screen scanned by the scanning unit 121, and outputs the information measured by the skin hardness measuring unit 123 to the screen.

That is, the monitor unit 122 allows a doctor to visually check the overall state of the cut skin tissue, and provides information on the skin hardness measured by the skin hardness measuring unit 123.

According to some embodiments of the present invention, the skin hardness measuring unit 123 is positioned to be supported by one side of the left side of the conveyor belt, a skin hardness measuring pin moves in x and y directions in the upper direction of the conveyor belt, and when a skin tissue is detected by a skin tissue sensor for the first time, it is lowered vertically and the skin hardness measuring pin positioned at a lower end measures the intensity of the force piercing through the scalp tissue.

As shown in FIG. 9, the skin hardness measuring unit 123 includes a hardness measuring support 123a, an x-axis moving bar 123b, and a y-axis moving unit 123c.

The hardness measuring support 123a is a rectangular plate shape formed upright on one side of the left side surface of the conveyor belt 110 in the traveling direction of the conveyor. An x-axis guide rail 123a-1 configured to be movable in the x direction, which is the conveyor traveling direction, is formed in the upper inner direction. This allows an x-axis moving bar 123b to reciprocate in the x direction within the range of the x-axis guide rail 123a-1.

The x-axis moving bar 123b is a straight bar formed perpendicular to the conveyor travel direction, is coupled to the x-axis guide rail 123a-1, and moves in the x direction which is the conveyor travel direction, and a y-axis guide rail 123b-1 which is movable in the y direction is formed on the bottom surface. Through this, the y-axis moving unit 123c is reciprocated in the y direction within the range of the y-axis guide rail 123b-1.

The y-axis moving unit 123c is inserted into the y-axis guide rail 123b-1 to form a hydraulic cylinder 123c-1 that moves in the y direction and moves up and down in the vertical lower direction, and a skin tissue sensor 123c-2 is formed on one side of a lower end of the hydraulic cylinder 123c-1, and a skin hardness measuring pin 123c-3 is formed on the lower end of the hydraulic cylinder 123c-1.

When the skin tissue sensor 123c-2 is located in front of the conveyor belt unit and when a skin tissue moving backwards is detected for the first time, the skin tissue sensor 123c-2 transmits the detection information to the follicle separation control unit 20 to stop the rotation of the conveyor belt 110. In addition, the hydraulic cylinder 123c-1 is moved down to measure the intensity of force of the skin hardness measurement pin 123c-3 piercing through the skin tissue to provide to the follicle separation control unit 20.

At this time, a pressure sensor is formed inside the skin hardness measurement pin 123c-3 to measure the pressure applied when the lower pin penetrates the skin tissue. The cutting force of the first cutting blade follicle separation control unit 134 and the second cutting blade follicle separation control unit 143 are set depending on the measured intensity of the pressure.

The lower pin 123c-4 is detachably coupled to the lower end of the skin hardness measuring pin 123c-3 to facilitate replacement and repair.

The first cutting unit 130 is positioned at a rear end of the scalp data analyzing unit 120 in the traveling direction of the conveyor belt to set the moving interval of the cutting blades according to the measured density from the scalp data, and cuts the scalp tissue into thin slices.

As shown in FIG. 10, the first cutting unit 130 includes a first cutting scanning unit 131, a first monitor 132, a first pin fixing unit 133, and a first cutting blade follicle separation control unit 134.

The first cutting scanning unit 131 having a rectangular shape is positioned in a vertical direction on one side of an upper end of the conveyor belt, and moves up and down along the scanning guide rail formed in the vertical direction, scanning the front of the cut skin tissue to check the cutting position and recording an image of slicing the skin tissue in real time.

The first cutting scanning unit 131 scans the whole skin tissue by adjusting the focal length by moving up and down in the vertical direction according to the variable cutting position, and it is possible to zoom in/out of a portion to be scanned to provide a partially enlarged and reduced screen to the first monitor unit 132.

The first monitor unit 132 enlarges and displays the screen scanned by the first cutting scanning unit 131, so that a doctor can visually check the state of the front of the skin tissue and the screen information of being cut into slices.

The pin fixing unit 133 is supported on one side of the left side of the conveyor belt, and detects the position of the skin tissue identified by the scan in the first cutting scanning part, so that the vertical support pins located on the left and right sides of the front and rear are moved to the x and y directions. When the skin tissue is detected by the skin tissue sensor coupled to each vertical support pin which is moved in the axial direction, the pin fixing unit 133 moves down in the vertical direction to fix the skin tissue.

As shown in FIG. 11, the pin fixing unit 133 includes a pin fixing support 133a, a front pin fixing bar 133b, and a rear pin fixing bar 133c.

The pin fixing support 133a has a rectangular plate shape formed upright on one side of the left side surface of the conveyor belt 110 in the traveling direction of the conveyor. An x-axis guide rail 133a-1 movable in the x direction which is the traveling direction of the conveyor is formed in the upper inside direction. This allows the front pin fixing bar 133b and the rear pin fixing bar 133c to reciprocate in the x direction within the range of the x-axis guide rail 133a-1.

The front pin fixing bar 133b has a straight bar shape formed perpendicular to the conveyor traveling direction, is coupled to the x-axis guide rail 133a-1, and is moved in the x direction which is the conveyor traveling direction, and a y-axis guide rail 133b-1 is formed longitudinally at the bottom surface, and a front left pin support 133b-2 and a front right pin support 133b-3 are coupled to the y-axis guide rail.

The skin tissue sensor 133b-3b is formed at one lower end of the hydraulic cylinder 133b-3a, and the front right pin 133b-3c is formed at the lower end of the hydraulic cylinder 133b-3a.

The rear pin fixing bar 133c is coupled to the x-axis guide rail 133a-1 in the shape of a straight bar formed perpendicularly to the conveyor traveling direction and moved in the x direction which is the conveyor traveling direction, and a y-axis guide rail 133c-1 is formed longitudinally at the bottom surface, and the rear left pin support 133c-2 and the rear right pin support 133c-3 are coupled to the y-axis guide rail.

The rear left pin support part 133c-2 has a hydraulic cylinder 133c-2a whose upper end is inserted into the y-axis guide rail 133c-1 and is moved in the y direction and moves up and down in the vertical lower direction. The skin tissue sensor 133c-2b is formed at one lower end of the cylinder 133c-2a, and a rear left pin 133c-2c is formed at the lower end of the hydraulic cylinder 133c-2a.

The skin tissue sensor 133c-3b is formed at one lower end of the cylinder 133c-3a, and a rear right pin 133c-3c is formed at the lower end of the hydraulic cylinder 133c-3a.

According to some embodiments of the present invention, the front left pin 133b-2c and the front right pin 133b-3c are spaced apart from the rear of the first cutting blade follicle separation control unit 140 so that the front left and right sides of the skin tissue are pierced and supported in the vertical direction. The rear left pin 133c-2c and the rear right pin 133c-3c support and pierce the rear left and right sides of the skin tissue in the vertical direction, so that when the front side of the skin tissue is cut in a sliced form through the first cutting blade 134d-1, the skin tissue is prevented from being pushed and moved to another position, supporting stable cutting to be performed.

Also, according to some embodiments of the present invention, the front left pin 133b-2c is detachably screw-coupled to the lower end of the hydraulic cylinder 133b-2a, the front right pin 133b-3c to the lower end of the hydraulic cylinder 133b-2a, the rear left pin 133c-2c to the lower end of the hydraulic cylinder 133c-2a, and the rear right pin 133c-3c to the lower end of the hydraulic cylinder 133c-a, respectively, thereby facilitating replacement and repair.

This is to facilitate replacement when the pin is damaged during the cutting operation, and to replace the follicles after the separation of the follicles from the patient's connective tissue, thereby maintaining a clean sanitary condition at the time of follicle separation of the next patient.

The first cutting blade follicle separation control unit 134 is supported and positioned on one side of the right side of the conveyor belt, and a hydraulic cylinder having a blade fixed to the front perpendicularly to the conveyor belt travel direction is formed, rotates at a constant speed in the vertical direction, and descends. The skin tissue is cut into slices while reciprocating back and forth by a hydraulic cylinder.

As shown in FIG. 12, the first cutting blade follicle separation control unit 134 includes a first cutting blade support 134a, a first cutting rotary unit 134b, a first cutting hydraulic cylinder 134c, and a first cutting blade frame 134d.

The first cutting blade support 134a is a rectangular plate shape formed upright on one side of the right side surface of the conveyor belt 110 in the traveling direction of the conveyor. An x-axis guide rail 134a-1 movable in the x direction which is the traveling direction of the conveyor is formed in the upper inner direction. This allows the first cutting rotary unit 134b to reciprocate in the x direction within the range of the x-axis guide rail 134a-1.

The first cutting rotary unit 134b supports the first cutting hydraulic cylinder 134c perpendicularly to the conveyor traveling direction and moves in the x direction, and a rotating shaft is formed based on one side of the upper center to rotate the first cutting hydraulic cylinder 134c in an up-and-down direction.

When the first cutting blade 134d-1 (see FIG. 13) cuts the skin tissue, the first cutting rotation part 134b slowly moves down within an angle range of 30° to −2°, and when the skin tissue is cut into slices, it moves up rapidly to prepare for the next process.

In a state where the first cutting blade 134d-1 is maintained at an angle of about 30° based on the first cutting rotary unit, when the skin tissue including a unit of follicles is located in the lower direction, the first cutting blade 134d-1 moves downward in the left and right directions, down to an angle of −2° to cut the skin tissue including the units of follicles in a slice form up to an upper side of the antibacterial cutting plate 111. This allows the skin tissue, including the units of follicles, to be completely cut into slices.

The first cutting hydraulic cylinder 134c is axially coupled perpendicularly to the upper inward direction of the first cutting rotary unit 134b and the first cutting blade frame 134d is coupled to the end of the cylinder to reciprocate the first cutting blade frame 134b through the reciprocation movement of the cylinder.

The first cutting hydraulic cylinder 134c reciprocates the first cutting blade frame 134d to stably cut the elastic skin tissue in a slice form.

The first cutting blade frame 134d is coupled to the end of the first cutting hydraulic cylinder 134c, and the first cutting blade 134d-1, which is easily coupled and detachably fitted in the lower direction, and a skin tissue sensor 134d-2 is formed at the front left and right sides.

Upon detection of the front part of the skin tissue positioned in a lower direction through skin tissue sensor 134d-2 formed at the front left and right sides, the first cutting blade frame 134d is lowered gradually in the vertical direction by the first cutting rotary unit 134b and reciprocated by the first cutting hydraulic cylinder 134c to cut the skin tissue into slices.

The second cutting unit 140 is formed upright in the rear end direction of the first cutting unit 130 to the left of the conveyor belt travel direction, the cutting blade is reciprocated in the vertical direction of the conveyor belt, and the each unit of follicles are individually separated by scanning each unit of follicles of the skin tissue cut into slices and cutting the left and right side portions respectively in the first cutting device.

According to some embodiments of the invention, the second cutting unit 140 further removes the tissue attached to the side portion of each incision of the units of follicles.

According to some embodiments of the present invention, the automatic hair-follicle separating apparatus 1 may further include a third cutting device unit (not shown) for removing tissue attached to the side portion of each unit of follicles cut between the second cutting unit 140 and the follicle selective unit 150.

As shown in FIG. 14, the second cutting unit 140 includes a second cutting scanning unit 141, a second monitor unit 142, and a second cutting blade follicle separation control unit 143.

The second cutting scanning unit 141 has a rectangular shape positioned in the center of one side of the upper end of the conveyor belt, and identifies the unit of follicles by scanning the connective tissue cut into slices by moving up and down along a scanning guide rail formed in a vertical direction. In addition, the position and direction information of the identified units of follicles is provided to the follicle separation control unit, and an image of scalp tissue being cut into slice shaped unit of follicles is taken in real time.

The second cutting scanning unit 141 moves up and down in the vertical direction and adjusts a focal length according to a variable cutting position to scan the connective tissue having a slice shape, and it is possible to zoom in/out of a portion to be scanned to provide a partially enlarged and reduced screen to the second monitor unit 142.

The second monitor unit 142 is located on the left side of the upright second cutting unit 140, and enlarges and displays the screen scanned by the second cutting scanning unit 141, so that a doctor can visually check the state of the slice shaped connective tissue and the screen information of cutting into units of follicles.

The second cutting blade follicle separation control unit 143 is a “ custom-character ” shaped frame rotated 90 degrees clockwise () across the top of the conveyor belt, and the cutting blade reciprocates in the lower direction of the frame. The left and right sides of the units of follicles included in the sliced connective tissue are cut at regular intervals and separated into units of follicles individually.

As shown in FIG. 15, the second cutting blade follicle separation control unit 143 includes a cutting blade support 143a, the second cutting rotary unit 143b, the second cutting hydraulic cylinder 143c, and the second cutting blade frame 143d.

The cutting blade support 143a is a “ custom-character ” shaped frame rotated 90 degrees clockwise () across the top of the conveyor belt in the vertical direction, and a vertical guide rail 143a-1 is formed in the lower direction which reciprocates the second cutting rotary unit 143b in the vertical direction.

The second cutting rotary unit 143b has an upper end coupled to the vertical guide rail 143a-1 of the cutting blade support 143a, and rotates in a horizontal direction to form the second cutting hydraulic cylinder 143c and the second cutting blade frame 143d.

The second cutting rotary unit 143b receives the position and direction information of the follicles primarily through the second cutting scanning unit 141 and secondarily receives the position and direction information of the follicles through the follicle position sensor 143d-2. After receiving the information and moving to a position in the side vertical direction of the follicles, the second cutting rotary unit 143b rotates in the horizontal direction according to the direction of the follicles to set the position and direction for cutting only the left and right sides of the follicle in the slice shaped connective tissue.

Through this, regardless of the condition of the worker, the left and right sides of the slice-shaped connective tissue can be cut and separated without damage according to the direction of the follicles, thereby improving the engraftment rate of the follicles.

The second cutting hydraulic cylinder 143c has a cylinder shape coupled to the lower end of the second cutting rotary unit 143b and moves the second cutting edge frame positioned at the lower end while moving down and up in the vertical direction.

The second cutting blade frame 143d has a rectangular frame shape coupled to the lower end of the second cutting hydraulic cylinder 143c, and the second cutting blade 143d-1 is detachably coupled to the lower end by fitting. The follicle position sensor 143d-2 is configured to detect the position and the direction of the follicle in the lower direction in the center of the front upper side.

According to some embodiments of the present invention, the second cutting blades 143d-1 may be detachably coupled in a fitted manner to facilitate replacement. This is to maintain clean hygiene at the time of separation of the follicles of the next patient by replacing when the follicles are separated after the clean cutting is not made due to damage or wear of the cutting blade.

The follicle position sensor 143d-2 detects the position and direction of the follicles before the second cutting hydraulic cylinder moves down and sets the secondary position and rotation angle of the second cutting rotary unit, whereby the follicle damage can be minimized by the second cutting blade to maximize the engraftment rate of follicles.

Follicle selective unit 150 is cut in the form of follicles to the bottom of the frame of the “ custom-character ” shape rotated 90 degrees clockwise formed upright to the rear end direction of the second cutting unit 140 to the left of the conveyor belt travel direction. Each follicle is picked up, transported in a vertical direction, and selected and classified according to the number of hairs formed in the separated units of follicles.

As shown in FIG. 16, the follicle selective unit 150 includes a selective support 151, a follicle selective transporting unit 152, a follicle selective sensor 153, a follicle selective pincer 154, and a follicle storing unit 155.

As shown in FIG. 17, the follicle selective transporting unit 152 has a cylindrical shape coupled to the vertical guide rail 151a of the selective transporting support 151 at the top thereof, is reciprocated in the vertical direction and supports the follicle selective hydraulic cylinder 152a and the follicle selective transporting frame 152b coupled in the lower direction.

The follicle selective hydraulic cylinder 152a has a cylindrical shape coupled to the lower end of the follicle selective transporting unit 152, and the follicle selective transporting frame 152b is coupled to the lower end thereof, and the connective tissue in the form of slices cut in units of follicles is cut in the lower direction. The position of the follicle selective transporting frame 152b is controlled by moving up and down depending on whether it is the skin tissue is positioned.

As shown in FIG. 18, the follicle selective transporting frame 152b has a semicircular vertical rotary unit 152b-1 shaft-coupled to the lower end of the follicle selective hydraulic cylinder 152a, and has a rectangular plate shaped frame formed in front of the vertical rotary unit, and a follicle bottom support frame 152b-2 and a follicle top support frame 152b-3 having the same length as the width of the conveyor belt in the front surface vertical direction of the frame.

As shown in FIG. 19, the follicle bottom support frame 152b-2 is positioned at the bottom of the sawtooth pattern of the antibacterial cutting plate 111 of the conveyor belt so that when the hair of the separated follicles is placed on the follicle support bottom silicon 152b-2a, the follicle support top silicon 152b-3a is engaged with the follicle support bottom silicon 152b-2a with the follicle support bottom silicon 152b-2a lowered vertically to pick up hair separated in units of follicles positioned therebetween.

Thereafter, the follicle selective hydraulic cylinder 152a is raised, and the vertical rotary unit 152b-1 is rotated so that the follicle selective transporting unit 152 moves in the vertical direction along the vertical guide rail 151a.

The follicle support top silicon 152b-3a and the follicle support bottom silicon 152b-2a are made of a material having frictional force and elasticity and having antibacterial properties.

This prevents the hair of the separated unit of follicles from being exposed to bacteria or strongly picked up and damaged by bending, and prevents the hair from sliding down and falling down.

The follicle selective sensor 153 is formed so as to match the height of the units of follicles picked up during vertical movement of the follicle selective transporting unit, and detects the number of hairs formed in each of the separate units of follicles passing through the front direction to transport to the follicle separation control unit 20.

As shown in FIGS. 20-22, when the number of hairs formed in the unit of follicles passing through is one, the first follicle selective pincer 154a is moved and the hair is picked up so as to be stored in the first follicle storage groove 155a.
