Description

Technical Field

[0001] The present invention relates to a hair transplant device (hair transplantation device), and more particularly, to a multi-channel hair transplant device in which a plurality of needles for hair transplantation (transplantation needles) are installed in a bundle shape. Background Art

[0002] A hair transplant device is a medical device for a hair surgery method, which collects hair from the hair area of the scalp and transplants it into the scalp of other bald areas with hair loss.

[0003] As an existing hair transplant device, for example, Korean Registered Patent No. 10-2048492 (invention name: hair transplantation machine having a plurality of needle channels arranged radially) discloses a bundle-shaped (multi-channel) hair transplant device in which a plurality of needle channels each composed of a needle (transplantation needle) and a needle shaft slidably inserted into the needle are installed.

[0004] However, since such an existing multi-channel hair transplant device is a manual hair transplant device, every time a user (a surgeon such as a doctor) transplants a hair follicle one by one onto the scalp, the user has to hold the handle of the hair transplant device and perform an action of pushing the main body of the hair transplant device downward. However, performing such a conventional hair transplant surgery that requires transplanting thousands of hair follicles within several hours places a huge physical burden on the user, resulting in a decrease in concentration and having a great impact on the success or failure of the surgery.

[0005] In addition, when replacing internal consumables or cleaning an existing hair transplant device, the upper cover of the hair transplant device needs to be separated from the outer shell of the hair transplant device and then the internal parts need to be taken out. However, due to the complex internal structure of the multi-channel hair transplant device, the disassembly and reassembly work of the hair transplant device are also inconvenient. Summary of the Invention

[0006] Problems to be Solved by the Invention

[0007] The present invention is proposed to solve the above problems of the prior art, and an object thereof is to provide an automatic hair transplant device capable of automatically performing the lifting action of the needle channels in a multi-channel hair transplant device.

[0008] In addition, an object of the present invention is to provide a hair transplant device having a structure that can easily attach and detach an electrified module for automatically performing the lifting action of the needle channels from the main body of the hair transplant device.

[0009] Solutions for Solving the Problems

[0010] According to an embodiment of the present invention, a multi-channel hair transplant device is disclosed.

However, it should be understood that for those skilled in the art, the present invention can be implemented even without these various specific details. It should be noted in advance that in some cases, in order to avoid confusion when describing the present invention, the description of parts that are well known in the art and have little relation to the present invention will be omitted.

[0039] Figure 1 is a perspective view of a multi-channel hair transplant device according to an embodiment of the present invention, Figure 2 is an exploded view of the multi-channel hair transplant device.

[0040] Referring to Figure 1 and Figure 2 , a multi-channel hair transplant device (hereinafter, simply referred to as "hair transplant device") according to an embodiment includes: a hair transplant device main body A, a needle channel bundle B, and an electrification module C. In one embodiment, the hair transplant device can be assembled by detachably combining the hair transplant device main body A, the needle channel bundle B, and the electrification module C.

[0041] The main body A of the hair transplantation device, as a module for accommodating the needle channel bundle B, includes: a housing 10; a nozzle portion 20 attached to the front end of the housing 10; and a lifting gear support portion ( Figure 5 1400 in it), which is arranged inside the housing 10 in a manner that can be lifted and lowered.

[0042] The housing 10 is a cylindrical component capable of accommodating the needle channel bundle B. The lifting gear support portion 1400 arranged inside the housing 10 is a cylindrical component, which can be clamped between the housing 10 and the needle channel bundle B accommodated therein, and can be lifted and lowered along the vertical direction relative to the housing 10.

[0043] On at least one side surface of the lifting gear support portion 1400, a connecting component 1450 can be attached. The connecting component 1450 is arranged to protrude to the outside of the housing 10 and is detachably connected to the sliding component ( Figure 8 530 in) of the electrification module C. Therefore, as will be introduced below, as the sliding component 530 moves along the vertical direction under the action of the driving portion ( Figure 8 510 in), the lifting gear support portion 1400 combined with the sliding component 530 will also move along the vertical direction together. For the specific structure of this main body A of the hair transplantation device, reference will be made to Figures 5 to 7 for later description.

[0044] In addition, in this specification, for each component such as the lifting gear support portion 1400, the sliding component 530, the needle channel 1200, the needle head 1220, and the needle shaft 1230, "rising", "retracting", or "receding" means that the component moves in a direction away from the scalp; "descending" or "advancing" of each component means that the component moves towards the scalp.

[0045] The needle channel bundle B includes: a bundle center component 1100; and a plurality of needle channels 1200, which are respectively combined to the outer surface of the above-mentioned bundle center component 1100 in a manner that can slide along the vertical direction. Each needle channel 1200 can be combined in a manner that can slide along the radial outside of the bundle center component 1100. In each needle channel 1200, a needle head 1220 protrudes at the front end. Inside the needle head 1220, a needle shaft ( Figure 4 1230 in) capable of sliding along the vertical direction is embedded. At the front end of the needle shaft 1230, that is, at the lower end of the needle shaft 1230 in the internal space of the needle head 1220, a hair follicle can be clamped, and in a state where the needle head 1220 is inserted into the patient's scalp, the needle shaft 1230 relatively descends to push the hair follicle into the scalp, thereby performing the hair transplantation operation. For the specific structure of the needle channel bundle B, reference will be made to Figure 3 and Figure 4 for later description.

[0046] The electrification module C is a component that descends from the upper part of the hair transplant device main body A and is detachably coupled to the hair transplant device main body A, and has a driving unit that automatically raises and lowers the lifting gear support unit 1400. The electrification module C includes: a cylindrical housing 30; and an upper cover 34 attached to the upper part of the housing. On the upper cover 34, terminals 341 (e.g., USB terminals) for communicating with the outside or receiving power from the outside and a button 342 for turning on / off the power of the electrification module C may be provided.

[0047] In one embodiment, the electrification module C may include: a drive button 525 for starting the lifting action of the lifting gear support unit 1400. For example, as Figure 1 shown, the drive button 525 may be located at the position of the user's thumb or index finger for the convenience of the user (e.g., doctor) to operate when holding the hair transplant device for a hair transplant operation.

[0048] The drive button 525 may communicate with the control unit ( Figure 8 310 in) inside the electrification module C by wire or wirelessly. When the user presses the drive button 525, under the control of the control unit 310, the sliding member 530 and the coupled lifting gear support unit 1400 perform the lifting action.

[0049] In an alternative embodiment, a motion sensor or a touch sensor may also be provided to replace the drive button 525. When the user touches the motion sensor or the touch sensor with a finger, the sensor will detect the finger, and the control unit 310 may perform the lifting action of the lifting gear support unit 1400. In another alternative embodiment, the hair transplant device may also include a gyroscope sensor instead of the drive button 525. The gyroscope sensor can detect the motion or state of the hair transplant device in real time (e.g., at what angle the hair transplant device stands or lies flat, etc.), and the control unit 310 may perform the lifting action of the lifting gear support unit 1400 according to the real-time detection signal of such a gyroscope sensor.

[0050] In one embodiment, the electrification module C may further include a separation button ( Figure 10 550 in), and the user can disassemble the hair transplant device by pressing the separation button 550, as Figure 2 shown. That is, as Figure 2 shown, separating the electrification module C from the main body A of the hair transplant device and pulling up the bundle center member 1100 exposed at the upper part of the hair transplant device main body A can separate the needle channel bundle B from the hair transplant device main body A, whereby the user can simply and quickly replace the needle channel bundle B.

[0051] Next, the needle channel bundle B will be described with reference to Figure 3 and Figure 4 .Figure 3 This is a diagram for explaining a needle channel bundle B according to an embodiment, Figure 4 in which a perspective view and a cross-sectional view of the needle channel 1200 are schematically shown.

[0052] Referring to Figure 3 , the needle channel bundle B includes: a bundle center member 1100; and a plurality of needle channels 1200, which are respectively coupled to the above-mentioned bundle center member 1100 in a manner capable of sliding in the vertical direction.

[0053] In one embodiment, the bundle center member 1100 may include: a cylindrical channel coupling portion 1110; and a head portion 1120 formed on the upper portion of the channel coupling portion 1110. The channel coupling portion 1110 and the head portion 1120 may be formed integrally, or may be separately manufactured and coupled. A through hole in the vertical direction may also be formed inside the channel coupling portion 1110 and the head portion 1120.

[0054] A plurality of slide rails 1115 are formed on the outer surface of the channel coupling portion 1110, which are formed at equal intervals in the radial direction with respect to the central axis of the channel coupling portion 1110. In one embodiment, the slide rails 1115 are formed by being engraved long along the upper and lower long side directions, and each needle channel 1200 engages with its respective slide rail 1115 in a manner capable of sliding in the vertical direction.

[0055] The head portion 1120 functions as a stopper, which prevents the needle channel 1200 engaged with the channel coupling portion 1110 from rising further upward. The inner diameter of the upper side of the head portion 1120 is the same as or smaller than the inner diameter of the central through hole 71 of the spring cover ( Figure 9 in 70) of the electrification module C. Thus, in a state where the electrification module C is coupled to the hair transplantation device main body portion A, the head portion 1120 is stuck in the through hole 71 of the spring cover 70, and the spring cover 70 can elastically press the bundle center member 1100 downward and provide support.

[0056] Referring to Figure 3 , Figure 4 , the needle channel 1200 includes: a body portion 1210 having a tubular internal space in the vertical direction; a hair root transplantation needle 1220 coupled to the lower portion of the body portion 1210; and a needle shaft 1230 slidably disposed in the internal spaces of the body portion 1210 and the needle head 1220.

[0057] The tubular inner space of the main body portion 1210 may be composed of a first diameter portion 1210a in the upper part with a relatively large diameter and a second diameter portion 1210b in the lower part with a relatively small diameter. The second diameter portion 1210b in the lower part has a diameter large enough for the needle shaft 1230 to pass through, and the first diameter portion 1210a in the upper part has a diameter large enough to accommodate the spring 1241 clamped around the needle shaft 1230. The needle head 1220 is inserted into and coupled to the main body portion 1210 through the open lower end portion of the second diameter portion 1210b of the main body portion 1210. The center of the needle head 1220 is hollow, that is, it is in the shape of a cylinder with a through-hole formed along the long side direction, and the through-hole of the needle head 1220 communicates with the inner space of the main body portion 1210.

[0058] The main body portion 1210 includes a side convex portion 1213 formed along the upper and lower long side directions. The side convex portion 1213 protrudes in the direction of the channel coupling portion 1110, that is, in the radially inner direction, and the convex shape of the side convex portion 1213 is set to be able to fit the shape of the groove portion of the slide rail 1115 of the channel coupling portion 1110. Therefore, the side convex portion 1213 of the main body portion 1210 engages with the slide rail 1115 of the channel coupling portion 1110, enabling the needle channel 1200 to slide in the up and down directions along the slide rail 1115.

[0059] The needle channel 1200 includes a clamping convex portion 1211 that extends from the main body portion 1210 in the direction opposite to the side convex portion 1213 of the main body portion 1210, that is, in the radially outer direction of the needle channel bundle B. The clamping convex portion 1211 includes: a slot 1215 formed along the up and down directions; a convex portion 1217 extending from the surface of the clamping convex portion 1211 in a further protruding manner in the radially outer direction; and ratchet gear teeth 1212 formed on the lower surface of the clamping convex portion 1211 and formed in a zigzag shape with a one-way inclination angle.

[0060] The slot 1215 is formed in the main body portion 1210 along the long side direction (up and down directions) and has a shape that is open to one side of the main body portion 1210. The slot 1215 is formed on the surface of the clamping convex portion 1211 in the radially outer direction along the up and down directions and communicates with the tubular inner space of the main body portion 1210 (that is, the space of the first diameter portion 1210a).

[0061] A needle shaft 1230 is disposed in the inner space of the main body portion 1210, and a lever 1231 is coupled to the upper end of the needle shaft 1230. The lever 1231 is guided by the slot 1215 and can slide in the up and down directions. A spring 1241 is clamped around the needle shaft 1230. The upper end portion of the spring 1241 is supported by the lever 1231, and the lower end portion of the spring 1241 is supported by the step portion between the first diameter portion 1210a and the second diameter portion 1210b in the main body portion 1210.

[0062] The upper end of the slot 1215 is open, and the upper cover 1250 can be fitted onto the open upper end. The upper cover 1250 functions as a stopper to prevent the lever 1231 from rising further in the upward direction. As Figure 3 shown, the upper surface of the upper cover 1250 may have a surface inclined in one direction so that the needle channel bundle B can rotate smoothly. That is, the surface of the upper cover 1250 is formed as an inclined surface that slopes downward along the rotation direction of the needle channel bundle to prevent the rotation of the needle channel bundle B from being affected by the push rod ( Figure 9 1530) that contacts the upper surface of the upper cover 1250.

[0063] The main body portion 1210 of the needle channel 1200 further includes a latching groove 1219. The latching groove 1219 is formed on the surface facing the radially outer side of the main body portion 1210 and is located below the latching protrusion 1211. The latching groove 1219 can partially accommodate the fastener ( Figure 7 1910) of the needle channel latching portion 1900.

[0064] In one embodiment, the main body portion 1210 may further include a rotor guide 1270, which is formed to extend downward. The rotor guide 1270 extends downward from the lower end of the main body portion 1210 and surrounds a part of the periphery of the outer peripheral surface of the needle head 1220. For example, in the embodiment shown in the figure, the rotor guide 1270 may be formed to surround approximately half (e.g., 180 degrees) of the periphery (i.e., 360 degrees) of the outer peripheral surface of the needle head 1220. However, this is only exemplary. For example, in an alternative embodiment, the rotor guide 1270 may also be formed to surround the needle head 1220 between 90 degrees and 270 degrees of the entire periphery (360 degrees) of the needle head 1220.

[0065] Next, with reference to Figures 5 to 7 the exemplary structure of the hair transplant device main body A will be described. Figure 5 is an exploded view of the hair transplant device main body A according to one embodiment; Figure 6 is a diagram for explaining the housing of the hair transplant device main body A; Figure 7 is a diagram for explaining the combination relationship between the housing and the lifting gear support portion according to one embodiment.

[0066] With reference to Figure 5 , the hair transplant device main body A according to one embodiment may include a cylindrical housing 10, a nozzle portion 20, a fastening ring 40, and a lifting gear support portion 1400.

[0067] The housing 10 is a cylindrical member with open upper and lower ends and a hollow interior for accommodating the needle channel bundle B and the lifting gear support portion 1400. A needle shaft engaging portion 1700 is attached to one side surface of the housing 10. The function of the needle shaft engaging portion 1700 is to temporarily stop the movement of the needle shaft 1230 that is slidably disposed inside the needle channel 1200 by engaging it.

[0068] Referring to Figure 5 and Figure 6 , the needle shaft engaging portion 1700 can be attached to approximately the middle height of the housing 10, and on the lower side and the upper side of the position where the needle shaft engaging portion 1700 is provided, a first slot 11 and a second slot 12 are respectively formed along the long side direction on the side surface of the housing 10. The first slot 11 is formed to avoid interference with the housing 10 when the first connection tab 1420 that protrudes radially outward from the lifting gear support portion 1400 moves in the vertical direction; the second slot 12 is formed to clamp the push rod ( Figure 9 of 1530) and guide its movement in the vertical direction while avoiding interference between the push rod 1530 and the housing 10.

[0069] The nozzle portion 20 is fastened to the lower end portion of the housing 10. For example, the nozzle portion 20 can be attached to the housing 10 through a fastening ring 40. In the illustrated embodiment, the inner thread of the fastening ring 40 and the outer thread 15 of the lower end portion of the housing 10 are formed in a shape that meshes with each other, and when the annular frame of the nozzle portion 20 is inserted into the inner side of the lower end portion of the housing 10, the fastening ring 40 is fastened to the lower end portion of the housing 10 and presses the nozzle portion 20, so that the nozzle portion 20 can be fastened to the housing 10.

[0070] The nozzle hole of the nozzle portion 20 is a through hole through which the needle tip 1220 of one needle channel 1200 can pass. Specifically, the nozzle hole can be formed to allow the needle tip 1220 of the needle channel and the nozzle guide 1270 around the needle tip to pass through.

[0071] The nozzle hole of the nozzle portion 20 is aligned with the push rod 1530 in a straight line. Therefore, when the push rod 1530 pushes one needle channel 1200 downward, the needle tip 1220 of the pushed needle channel 1200 protrudes a predetermined length downward through the nozzle hole to the lower part of the hair transplant device.

[0072] The lifting gear support portion 1400 is a member that is sandwiched between the needle channel bundle B and the inner side surface of the housing 10 and moves up and down relative to the housing 10. The lifting gear support portion 1400 is formed in a cylindrical shape to surround the needle channel bundle B, and a wedge-shaped convex portion 1410 is formed on the outer edge of the upper end portion.

[0073] On the outer peripheral surface of the side of the lifting gear support portion 1400, a first connection tab 1420 and a second connection tab 1430 protruding along the radial direction are provided. The first connection tab 1420 protrudes to form an attachment needle channel engaging portion 1900, and the second connection tab 1430 is formed to attach a connection member 1450. Through the connection member 1450, the lifting gear support portion 1400 is integrally connected to the sliding member ( Figure 8 of 530) of the electrification module C. In addition, at this time, in order to prevent the up and down movement of the first connection tab 1420 and the second connection tab 1430 from interfering with the housing 10, a first slot 11 and a third slot 14 are respectively formed on the side of the housing 10.

[0074] The lifting gear support portion 1400 is a generally cylindrical member and is arranged to surround the outer peripheral surface of the needle channel bundle B. The upper end surface of the cylindrical lifting gear support portion 1400 is formed to be able to contact the lower end surface of the engaging convex portion 1211 of the needle channel 1200, that is, the lower surface of the ratchet gear teeth 1212. That is, a sharp-shaped wedge-shaped convex portion 1410 is continuously formed on the upper surface of the lifting gear support portion 1400, and the wedge-shaped convex portion 1410 is formed to have the same number as the ratchet gear teeth 1212 of the needle channel bundle B to engage with the plurality of ratchet gear teeth 1212 of the needle channel bundle B.

[0075] Refer to Figure 6 of (b) and Figure 7 , the housing 10 may have a ratchet bracket portion 1300 engraved on the inner side surface. The ratchet bracket portion 1300 protrudes inwardly on the inner side surface of the housing 10.

[0076] The ratchet bracket portion 1300 is engraved and protrudes on the inner side surface of the housing 10 in a manner that surrounds the inner side surface in a circle. In order to prevent interference with the first and second connection tabs 1420 and 1430 of the lifting gear support portion 1400, for the positions of the first slot 11 and the third slot 14 formed in the specified side area of the housing 10, at least a part of the ratchet bracket portion 1300 may not be formed.

[0077] The ratchet bracket portion 1300 may be composed of an upper surface 1310 engraved and protruding in a wedge shape and a lifting guide 1350 engraved and protruding along the up and down direction. The wedge-shaped upper surface 1310 may be formed to contact the lower surface of the ratchet gear teeth 1212 of the needle channel 1200. That is, the upper surface 1310 of the ratchet bracket portion 1300 is formed in a serrated shape with a one-way inclination angle to engage with the ratchet gear teeth 1212. The lifting guide 1350 can guide the lifting movement in the clearance space inside the housing 10 without shaking during the lifting movement of the lifting gear support portion 1400.

[0078] In one embodiment, a needle shaft engaging portion 1700 is attached to one side surface of the outer shell 10. The needle shaft engaging portion 1700 is disposed on the side surface radially outside the needle passage 1200 that is pushed downward by the push rod 1530. The needle shaft engaging portion 1700 functions to temporarily stop the needle shaft 1230 in the needle passage 1200 from rising during the upward movement after the needle passage 1200 is pushed downward by the push rod 1530.

[0079] Referring to Figure 7 , the needle shaft engaging portion 1700 may include: a fastener 1710; a fastener receiving portion 1720 for receiving the fastener 1710; and an elastic member 1730 interposed between the fastener 1710 and the fastener receiving portion 1720. The fastener receiving portion 1720 may be fixedly bolted to the side surface of the outer shell 10 through bolt grooves in the extension regions on the left and right side surfaces, for example. The fastener receiving portion 1720 has a space inside it that allows the fastener 1710 to enter, and an elastic member 1730 such as a spring is interposed in the space. The fastener 1710 may pass through the through-hole 13 of the outer shell 10 and engage with the lever 1231 of the needle passage 1200 located inside the outer shell 10.

[0080] When no force is applied to the fastener 1710, since the fastener 1710 protrudes from the fastener receiving portion 1720 (radially inwardly of the needle passage bundle B), it contacts the lever 1231 when the lever 1231 makes an up-and-down sliding movement. The lever 1231 is formed such that when the lever 1231 descends downward from above the fastener 1710, the lever 1231 pushes the fastener 1710 toward the fastener receiving portion 1720 and descends, and when the lever 1231 ascends upward from below the fastener 1710, the upper surface of the lever 1231 is caught by the fastener 1710 and stops rising.

[0081] A protrusion 1217 protruding in the radially outer direction of the needle passage bundle B is formed on the side surface of the slot 1215 of the needle passage 1200. The protrusion 1217 protrudes in the radially outer direction to the same extent as the lever 1231 or protrudes more outwardly than the lever 1231. In addition, the left and right widths of the fastener 1710 are set to interfere not only with the lever 1231 but also with the up-and-down movement of the protrusion 1217.

[0082] Therefore, whether the needle channel 1200 rises upward from below the fastener 1710 or descends downward from above, the protrusion 1217 can push the fastener 1710 toward the fastener receiving portion 1720 and raise or lower the needle channel 1200. Thus, if the main body portion 1210 of the needle channel 1200 rises when the upper surface of the lever 1231 is caught by the fastener 1710 and the lever 1231 stops rising, the protrusion 1217 can push the fastener 1710 toward the fastener receiving portion 1720 and rise. At this time, the engagement of the lever 1231 is released, and thus the needle shaft 1230 can also rise together with the main body portion 1210.

[0083] The needle channel engaging portion 1900 is a device that engages one needle channel 1200 that is pushed down by the push rod 1530, so that the needle channel 1200 moves together with the up-and-down movement of the lifting gear support portion 1400.

[0084] In one embodiment, the needle channel engaging portion 1900 may include: a fastener 1910; a fastener receiving portion 1920 for receiving the fastener 1910; and an elastic member 1930 interposed between the fastener 1910 and the fastener receiving portion 1920. The fastener receiving portion 1920 may be coupled to the first connection tab 1420 of the lifting gear support portion 1400 by a coupling method such as a snap fit or a bolt fastening. The fastener receiving portion 1920 has a space inside that allows the fastener 1910 to enter, and an elastic member 1930 such as a spring is interposed in the space. The fastener 1910 can elastically move in the radially inner direction and engage with the engagement groove 1219 of the needle channel 1200, thereby temporarily restricting the upward movement of the needle channel 1200.

[0085] With this structure, in the engaged state where the fastener 1910 is inserted into the engagement groove 1219, the needle channel 1200 moves together with the up-and-down movement of the lifting gear support portion 1400. However, in the above engaged state, when the needle channel bundle B rotates counterclockwise, the fastener 1910 retreats toward the fastener receiving portion 1920 and the engagement is released, and when the needle channel bundle B rotates by one channel, the fastener 1910 engages with the engagement groove 1219 of another needle channel 1200.

[0086] In addition, with this structure, each time the lifting gear support part 1400 performs one up-and-down action, the needle channel bundle B can be rotated by a specified angle corresponding to the size of one channel. The rotation of the needle channel bundle B and the lifting of the needle channel 1200, as well as the lifting action of the needle shaft 1230, which are achieved through the ratchet bracket part 1300, the lifting gear support part 1400, the needle shaft clamping part 1700, and the needle channel clamping part 1900, have been disclosed in, for example, Korean Patent No. 10-2048492 (Hair transplant machine having a plurality of needle channels arranged radially), and thus detailed description is omitted in this specification.

[0087] Figure 8 is an exploded view of the electrified module C according to an embodiment. Referring to Figure 8 , the electrified module C has a driving part, and the above driving part is detachably coupled to the upper part of the hair transplant device main body part A and can lift the lifting gear support part 1400 of the hair transplant device main body part A. In one embodiment, the electrified module C includes: an outer housing 30, an inner housing 50, and an upper cover 34.

[0088] The outer housing 30 is a cylindrical member surrounding the inner housing 50, and the upper cover 34 is attached to the upper end. The inner housing 50 is a cylindrical member with a closed upper part and has an inner space for accommodating the hair transplant device main body part C. A driving part 510, a control part 310, and a battery 311 may be provided on the upper side of the closed upper part of the inner housing 50.

[0089] The control part 310 is used to control the operation of the driving part 510. For example, it can be implemented through a PCB board and a microprocessor installed thereon, etc. The battery 311 can be, for example, a coin-type battery and supplies power to the control part 310 and the driving part 510. In an alternative embodiment, the battery 311 may also be omitted and powered from the outside.

[0090] There is a space between the inner housing 50 and the outer housing 30 for placing some components of the electrified module C. For example, in the illustrated embodiment, a sliding member 530 and a power transmission member for lifting the sliding member 530 are provided in the above space, and such components can be attached to the outer surface of the inner housing 50 or the inner surface of the outer housing 30.

[0091] In one embodiment, the driving part 510 can be a motor, but is not limited thereto, and can be implemented by any other driving source driven by electricity. In the illustrated embodiment, a first rotating member is directly or indirectly (through a gearbox, etc.) provided on the rotating shaft of the driving part 510, and a second rotating member is provided below the first rotating member at a spaced-apart manner.

[0092] In order to transmit the rotational power of the first rotating member to the second rotating member, a power transmission member is further provided between the first rotating member and the second rotating member. The power transmission member is wound around the first and second rotating members to form a closed loop, thereby transmitting the rotational power of the first rotating member to the second rotating member. In addition, since the sliding member 530 is coupled to the above-mentioned power transmission member, it can move in the vertical direction by the drive of the drive unit 510.

[0093] In the embodiment shown in the figure, the first rotating member can be implemented by the first pulley 521; the second rotating member can be implemented by the second pulley 522; and the power transmission member can be implemented by the lead wire 523. However, the first and second rotating members and the power transmission member are not limited to the above components. For example, in other alternative embodiments, the first rotating member and the second rotating member can be sprockets respectively, and the power transmission member can be a chain.

[0094] Figure 9 It is a cross-sectional view schematically showing the internal structure of the internal housing 50. Referring to the accompanying drawings, the internal housing 50 is a cylindrical member with an open lower part, and a spring 1520, a spring cover 70, and a push rod 1530 can be provided in the upper part inside.

[0095] The push rod 1530 can be guided by the guide portion 52 formed along the long side direction on the inner side surface of the internal housing 50 and move in the vertical direction. The push rod 1530 serves to push one needle channel 1200 of the needle channel bundle B downward in a state where the electrification module C is coupled to the hair transplant device main body portion A.

[0096] The push rod 1530 has a spring insertion portion 1531 extending upward, and the spring 1540 is inserted into the spring insertion portion 1531. An internal space, that is, a spring accommodation portion 51, is formed further upward at the upper part of the push rod 1530, which can accommodate the spring 1540 and at least a part of the spring insertion portion 1531 inserted therein. That is, when the push rod 1530 rises to the maximum, the spring insertion portion 1531 of the push rod 1530 can rise into the interior of the accommodation portion 51 (that is, Figure 9 the state shown), and when the push rod 1530 descends due to the elasticity of the spring 1540, it can descend to the engaging protrusion 52a at the lower end of the guide portion 52. The engaging protrusion 52a, which is a protrusion protruding inwardly of the internal housing 50, not only serves as a stopper for the downward movement of the push rod 1530, but also can prevent the push rod 1530 from disengaging from the guide portion 52.

[0097] A spring 1520 is provided at the center of the upper inner side of the inner housing 50. The spring cover 70 is elastically attached to the inner housing 50 while covering the lower side of the spring 1520. A through-hole 71 may be formed at the center of the spring cover 70, and the through-hole 71 has a diameter through which the bundle center member 1100 of the needle channel bundle B can be inserted. Thus, in a state where the electrified module C is combined with the hair transplant device main body A, for the spring cover 70, the upper end of the bundle center member 1100 of the needle channel bundle B is inserted into the through-hole 71 of the spring cover 70, and in this state, the spring cover 70 functions to elastically press the needle channel bundle B downward through the spring 1520, so that the needle channel bundle B does not shake inside the hair transplant device main body A and is firmly positioned.

[0098] In a preferred embodiment, when a replacement or sterilization operation of the needle channel bundle B is to be performed, as Figure 2 shown, the hair transplant device can be separated by module by removing the electrified module C from the hair transplant device main body A. That is, when the separation button ( Figure 10 550 in) provided at the lower end of the electrified module C is pressed by hand, the fastening between the electrified module C and the hair transplant device main body A is released, so that the electrified module C can be separated from the hair transplant device main body A, and then the needle channel bundle B accommodated in the hair transplant device main body A can be taken out.

[0099] At this time, since the push rod 1530 is not disengaged downward due to the engagement protrusion 52a of the guide portion 32 but is clamped in the guide portion 52, and the spring cover 70 is also elastically attached to the inner housing 50, when the electrified module C is Figure 2 separated from the hair transplant device main body A as shown, components of the electrified module C such as the push rod 1530 or the spring 1520 do not disengage from the electrified module C and can be separated from the hair transplant device main body A.

[0100] Next, the setting, operation structure of the sliding member 530, and the structure for loading and unloading the electrified module C from the hair transplant device main body A will be described with reference to Figures 10 to 14 . In the following embodiments, it is assumed that the first and second rotating members are pulleys 521 and 522 respectively, and the power transmission member is a lead 523.

[0101] Figure 10 Schematically shows the shape of the electrified module C in a state where the outer housing 30 is removed, that is, the external structure of the inner housing 50 of the electrified module C. For ease of explanation, illustrations of components such as the control unit 310 and the battery 311 are omitted. Figure 11 Only the components required to drive the sliding member 530 are schematically shown, Figure 12 which is a perspective view of the sliding member 530.

[0102] Reference Figure 10 and Figure 11 , a driving part 510 is provided at the upper part of the inner housing 50, and the first pulley 521 is directly or indirectly connected to the driving shaft of the driving part. A second pulley 522 is provided at the lower part of the inner housing 50, and a lead wire 523 serving as a power transmission member is wound between the first and second pulleys 521 and 522. A sliding member 530 is coupled to a wire on one side of the lead wire 523. Thus, as the lead wire 523 moves by the driving part 510, the sliding member 530 moves up and down.

[0103] Reference Figure 12 , the sliding member 530 includes: a main body part 5310, a clamping plate 5320, and a spring 5330 clamped between the two. The main body part 5310 has a lead wire fixing part 5311 for coupling with the lead wire 523. For example, by winding the lead wire 523 around the lead wire fixing part 5311 more than once, the main body part 5310 can be fixed to the lead wire 523.

[0104] A clamping plate mounting part 5313 for mounting the clamping plate 5320 may be formed on the front surface of the main body part 5311. The clamping plate 5320 is a plate-shaped member having a through hole 5321 formed in the center, and it can be coupled to the main body part 5310 in a state of being clamped between the clamping plate mounting part 5313 and the guide piece 5316 and being able to slide left and right. The clamping plate mounting part 5313 has a spring support part 5315 protruding from the surface toward the through hole 5321 of the clamping plate 5320, and with the spring 5330 inserted into the through hole 5321, one end of the spring is supported by the spring support part 5315. At this time, the other end of the spring 5330 is inserted into a spring insertion part 5322 protruding into the through hole 5321 of the clamping plate 5320, thereby preventing the spring 5330 from coming off.

[0105] A clamping groove 5321 is formed on one side surface of the clamping plate 5320. As Figure 10 shown, the clamping protrusion 1451 of the connection member 1450 coupled to the lifting gear support part 1400 can be inserted into the clamping groove 5321. Therefore, in a state where the clamping protrusion 1451 is caught by the clamping groove 5321, when the sliding member 530 moves up and down, the lifting gear support part 1400 also moves up and down together.

[0106] Figure 13 The driving button 525 and the stopper member 540 provided outside the inner housing 50 are schematically shown. Reference Figure 10 and Figure 13, the inner housing 50 includes: a stopper member 540 disposed adjacent to a movement path along which the sliding member 530 moves in the vertical direction; and a drive button 525 disposed near the lower end of the stopper member 540. In one embodiment, the stopper member 540 may be a long rod shape. The upper end portion 5401 of the stopper member 540 is coupled to the inner housing 50. A convex portion 5402 facing the sliding member 530 is formed at the lower end portion of the stopper member 540. Thus, as Figure 10 shown, it is arranged such that the convex portion 5402 can interfere with the upward movement path of the sliding member 530 in a state where the sliding member 530 has descended to the lowermost end. For example, in the embodiment shown in Figure 10 , the convex portion 5402 is located above the engaging plate 5320 of the sliding member 530, thereby preventing the sliding member 530 from rising.

[0107] As Figure 13 shown, an inclined surface 5403 is formed at the lowermost end of the stopper member 540, and an inclined surface 5251 opposite to the inclined surface 5403 may also be formed on the drive button 525. Therefore, when the user presses the drive button 525, the drive button 525 will move in the Y-axis direction shown in Figure 13 towards the stopper member 540, and since the rod-shaped stopper member 540 has some elasticity in structure, the convex portion 5402 of the stopper member 540 will move in the X-axis direction away from the sliding member 530.

[0108] As described above, when the user presses the drive button 525, the convex portion 5402 disengages from above the sliding member 530, so that the sliding member 530 can move upward without interference from the convex portion 5402. In the illustrated embodiment, the movement of the convex portion 5402 is achieved by the inclined surfaces 5403, 5251 facing each other, but this is only exemplary, and obviously the movement of the convex portion 5402 can be achieved by other methods.

[0109] In addition, although not shown, the drive button 525 and the control unit 310 are connected by wire or wirelessly for electrical communication. Therefore, when the drive button 525 is pressed, the electrical signal generated thereby can be transmitted to the control unit 310. Thus, when the user presses the drive button 525, the convex portion 5402 retreats from the sliding member 530, and at the same time, the drive unit 510 is driven under the control of the control unit 310, so that the sliding member 530 can rise upward.

[0110] Figure 14 is a diagram illustrating a structure for loading and unloading a housing according to an embodiment. For ease of explanation, only the separation button 550, the fastening rod 560, and the sliding member 530 provided in the inner housing 50 are shown.

[0111] Reference Figure 10 and Figure 14 , the internal shell 50 includes: a fastening rod 560, which is arranged at a position adjacent to the moving path of the sliding component 530 moving along the up-down direction; and a separation button 550, which is arranged below the fastening rod 560. In one embodiment, the fastening rod 560 can be a long rod, the upper end 5601 is combined with the internal shell 50, and the lower end is an open end and is formed with a slope 5603. In addition, a fastening piece 5602 is formed at a position adjacent to the lower end of the fastening rod 560 to protrude and extend with a length that can penetrate the through-opening 53 of the internal shell 50. Since the through-opening 53 of the internal shell 50 is formed at the groove portion ( Figure 6 17) in (a), so that the fastening piece 5602 is inserted into the groove portion 17 of the hair transplanter main body A, thereby enabling the motorized module C to be fastened to the hair transplanter main body A.

[0112] like Figure 14 As shown, a slope 5603 is formed at the lower end of the fastening rod 560, and a slope 551 opposite to the slope 5603 is also formed at the upper part of the separation button 550. Therefore, when the user presses the separation button 550, the fastening piece 5602 of the fastening rod 560 moves along the Y axis in a direction away from the groove portion 17 of the hair implant body A, thereby releasing the fastening of the motorized module C and the hair implant body A.

[0113] In addition, when the motorized module C is fastened to the hair implant body A, the engaging protrusion 1451 of the connecting member 1450 is inserted into the engaging groove 5321 of the engaging plate 5320 of the sliding member 530. Therefore, in order to separate the motorized module C from the hair implant body A, the connection between the engaging groove 5321 of the engaging plate 5320 and the engaging protrusion 1451 needs to be released. Figure 14 As shown, an inclined surface 552 is formed on the upper portion of the separation button 550, and an inclined portion 5323 is formed in the region of the clamping plate 5320 that interferes with the inclined surface 552. Therefore, when the separation button 550 rises upward, the clamping plate 5320 will move away from the clamping protrusion 1451 along the X-axis direction.

[0114] Therefore, according to the above structure, when the user presses the separation button 550, the fastening plate 5602 of the fastening rod 560 is removed from the groove portion 17 of the hair transplanter main body A, and at the same time, the clamping plate 5320 will also slide and move away from the clamping protrusion 1451. At this time, the user can lift the motorized module C upward and separate the motorized module C from the hair transplanter main body A.

[0115] Figure 15An alternative embodiment for driving the sliding member 530 is shown, and similar to Figure 11 Similarly, only the components required to drive the sliding member 530 are schematically shown.

[0116] Referring to Figure 15 , in the above alternative embodiment, the inner housing 50 may include: a gearbox 571 connected to the drive shaft of the drive unit 510; a screw shaft 580 extending downward from the gearbox 571; a support portion 572 for supporting the lower end portion of the screw shaft 580; and a sliding member 590 that moves in the vertical direction through the screw shaft 580. That is, in the above alternative embodiment, a screw shaft is used to move the sliding member 590 instead of a pulley or a lead wire.

[0117] The sliding member 590 may include: a main body portion 5910, a clamping plate 5920, and a spring 5930. Since the clamping plate 5920 and the spring 5930 have the same or similar structure as the sliding member 530 in Figures 10 to 14 , the description thereof is omitted. The main body portion 5910 has the same structure as the main body portion 5310 in Figures 10 to 14 except that it is arranged to allow the screw shaft 580 to pass through and move up and down by the rotation of the screw shaft 580.

[0118] Therefore, according to the above structure, the screw shaft 580 is rotated by the drive of the drive unit 510, whereby the sliding member 590 moves in the vertical direction, so that the gear support portion 1400 can be lifted and lowered.

[0119] As described above, those skilled in the art to which the present invention pertains can make various modifications and deformations from the descriptions in the above specification. Therefore, the scope of the present invention should not be limited by the above embodiments, but should be determined by the appended claims and the scope equivalent to the appended claims.
