Description
Technical Field
[0001] This utility model relates to the field of hair follicle transplantation technology, and in particular to a novel hair follicle transplantation pen. Background Technology
[0002] A hair follicle transplant pen is a tool specifically designed for hair transplantation. It consists of a hollow needle, a needle core, a needle tube, a needle connector, and an insertion device. The doctor will place the extracted hair follicles into the hollow needle of the transplant pen and then use the insertion device to implant the hair follicles into the transplant area.
[0003] The authorized publication number "CN208864369U" discloses a hair follicle transplant pen, which describes the following technical problem: "This utility model has a simple structure and few parts; the inner tube and outer tube are threadedly connected, and the length of the needle core can be adjusted by rotating the inner tube to meet the requirements of various implantation depths in hair transplantation surgery; the needle tube is easy to replace, and when replacing the needle tube, simply unscrew the needle tube from the outer tube."
[0004] In the process of implementing this patent, the applicant discovered the following technical problems:
[0005] Because the needle tip of the hair follicle implantation pen in this patent lacks a limiting mechanism, it is difficult to ensure that the insertion depth of the reamer needle remains consistent each time during the implantation procedure. Inconsistent implantation depth will have a certain impact on hair follicle growth. At the same time, after the hair follicle is pushed in by the needle, the friction between the inner wall of the reamer needle and the hair follicle will cause the inner wall of the reamer needle to carry the hair follicle a certain distance outward on the scalp when the reamer needle is pulled out, or even pull it out of the hole, thus requiring re-implantation and causing secondary damage to the hair follicle, affecting hair follicle growth and survival rate. Therefore, a new type of hair follicle implantation pen is needed to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content
[0006] Based on this, a novel hair follicle transplant pen is provided to solve the following technical problems mentioned in the background art: Because the needle part of the transplant pen designed in this patent lacks a limiting function, it is difficult to ensure that the insertion depth of the reamer needle is consistent each time during the transplantation procedure. Inconsistent transplantation depth will have a certain impact on hair follicle growth. At the same time, after the hair follicle is pushed in by the pusher needle, the friction generated between the inner wall of the reamer needle and the hair follicle will cause the inner wall of the reamer needle to carry the hair follicle a certain distance outward on the scalp when the reamer needle is pulled out, or even bring it out of the hole, thus requiring re-transplantation, causing secondary damage to the hair follicle, affecting hair follicle growth and survival rate.
[0007] The present invention adopts the following technical solution:
[0008] The novel hair follicle transplant pen specifically includes a pen body, a handle module fixedly connected to the lower outer side of the pen body, a control module installed inside the handle module, a top skin component at the bottom of the pen body, a transplant component inside the pen body, and a replacement component at the bottom of the transplant component.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0028] As in the background art, because the needle part of the implantation pen designed in this patent lacks a limiting function, it is difficult to ensure that the insertion depth of the reamer needle is consistent each time during the implantation surgery. Inconsistent implantation depth will have a certain impact on the growth of hair follicles. At the same time, after the implantation pen pushes the hair follicle in through the pusher needle, the friction generated between the inner wall of the reamer needle and the hair follicle will cause the inner wall of the reamer needle to carry the hair follicle a certain distance outward on the inside of the scalp when the reamer needle is pulled out, or even bring it out of the hole, thus requiring re-implantation, causing secondary damage to the hair follicle, affecting hair follicle growth and survival rate.
[0029] To address this technical problem, this invention provides a novel hair follicle transplant pen. By designing the pusher and the reamer to move in opposite directions, the reamer can be pulled out of the wound while the pusher advances the hair follicle. This prevents the reamer from carrying the hair follicle along with the follicle during subsequent needle removal, thus avoiding damage to the hair follicle during secondary transplantation. This allows for a single hair follicle transplantation procedure, achieving efficient, safe, and rapid results while improving hair follicle survival rates.
[0030] For details, please refer to Figures 1-2 A novel hair follicle transplant pen specifically includes a pen body 1, a grip module 2 fixedly connected to the lower outer side of the pen body 1, a control module 3 installed inside the grip module 2, a top skin component 4 provided at the bottom of the pen body 1, a transplant component 5 provided inside the pen body 1, and a replacement component 6 provided at the bottom of the transplant component 5.
[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0032] Example 1:
[0033] Please refer to Figures 1-6 A novel hair follicle transplant pen includes a pen body 1, a grip module 2 fixedly connected to the lower outer side of the pen body 1, a control module 3 installed inside the grip module 2, a top skin component 4 at the bottom of the pen body 1, a transplant component 5 inside the pen body 1, and a replacement component 6 at the bottom of the transplant component 5.
[0034] By setting the top skin component 4, the depth to which the replacement component 6 is inserted into the patient's scalp can be limited;
[0035] By setting up the planting component 5, the needle can be pulled out while the hair follicle is being pushed in, thus avoiding the needle from having a pulling effect on the hair follicle and affecting its growth.
[0036] By replacing component 6, the needle tip can be easily replaced when it becomes dull, thus replacing the entire hair transplant pen and reducing the waste of materials in hair follicle surgery.
[0037] The top cover assembly 4 includes a pen tip 7 and a top cover tube 8. The pen tip 7 is threadedly connected to the bottom of the pen body 1, and the top cover tube 8 is rotatably connected to the bottom of the pen tip 7. A first reserved groove is opened on the side wall of the top cover tube 8, and the bottom of the top cover tube 8 away from the first reserved groove is inclined.
[0038] The planting component 5 includes a support plate 9, a first turntable 10, a first fixing rod 11, a first connecting plate 12, a pusher 13, and a first rotating seat 14. The two ends of the inner side of the pen body 1 are fixedly connected to the support plate 9. The two sides between the two support plates 9 are rotatably connected to the first turntable 10. The first fixing rod 11 is fixedly connected between the two first turntables 10, and the first fixing rod 11 is located away from the center of the first turntable 10. The first connecting plate 12 is rotatably connected to the outer side of the first fixing rod 11. The pusher 13 is provided at the bottom of the first connecting plate 12. The first rotating seat 14 is fixedly connected to the top of the pusher 13. The first rotating seat 14 and the bottom of the first connecting plate 12 are rotatably connected.
[0039] The planting assembly 5 also includes a second turntable 15, a second fixing rod 16, a second connecting plate 17, a movable ring 18, and a second rotating seat 19. The two sides of the two support plates 9 are rotatably connected to the second turntable 15, and the two second turntables 15 are located on both sides of the two first turntables 10. The second fixing rod 16 is fixedly connected between the second turntable 15 and the first turntable 10. The second fixing rod 16 is located away from the center of the first turntable 10, and the second fixing rod 16 and the first fixing rod 11 are symmetrically arranged. The second connecting plate 17 is rotatably connected to the outside of the second fixing rod 16. The movable ring 18 is located below the outside of the pusher 13. The two sides of the top of the movable ring 18 are fixedly connected to the second rotating seat 19. The bottom of the second connecting plate 17 is rotatably connected to the second rotating seat 19.
[0040] The planting component 5 also includes a third fixing rod 20, a first gear 21, a motor 22, and a second gear 23. The third fixing rod 20 is fixedly connected to the center position of the second turntable 15 on the side away from the first turntable 10. The side of the third fixing rod 20 away from the second turntable 15 is rotatably connected to the inner wall of the pen body 1. The first gear 21 is fixedly connected to the outer side of one of the third fixing rods 20. The motor 22 is fixedly connected to the inner wall of the pen body 1, and the motor 22 is located above the side close to the first gear 21. The motor 22 is electrically connected to the control module 3. The output end of the motor 22 is fixedly connected to the second gear 23, and the second gear 23 is meshed with the top of the first gear 21.
[0041] The replacement component 6 includes a needle seat 24 and a reaming needle tube 25. The needle seat 24 is threaded to the outer bottom of the movable ring 18. The reaming needle tube 25 is fixedly connected to the bottom of the needle seat 24. The inner side of the reaming needle tube 25 is clearance-fitted with the push needle 13. The reaming needle tube 25 is clearance-fitted with the inner side of the top tube 8. A second reserved groove is opened on the side wall of the reaming needle tube 25, and the position and size of the second reserved groove correspond to the first reserved groove.
[0042] Specifically: By setting the bottom of the apical tube 8 at an angle, it is easier for doctors to maintain the stability of the implantation pen when it is tilted while holding the pen.
[0043] The hair follicle is placed inside the enlarging needle tube 25 through the second reserved groove and the first reserved groove;
[0044] The control module 3 is configured as an SC-200 controller. Through the configuration of the control module 3, the motor 22 can drive the second gear 23 to rotate, thereby driving the first gear 21, which is meshed with the second gear 23, to rotate. Through the connection of the third fixed rod 20, the second turntable 15 can be driven to rotate synchronously with the first gear 21, thereby driving the second fixed rod 16 to move around the center of the second turntable 15. Thus, the second fixed rod 16 can drive the second connecting plate 17 to move up and down between the first turntable 10 and the second turntable 15.
[0045] Through the linkage setting of the second connecting plate 17, the movable ring 18 can be driven to move up and down synchronously on the outside of the push needle 13, thereby driving the needle seat 24 and the pore-expanding needle tube 25 connected to the bottom of the movable ring 18 to move synchronously. After the hair follicle is placed inside the pore-expanding needle tube 25, the pore-expanding needle tube 25 is driven to extend out of the inside of the apical tube 8 and be inserted into the inside of the patient's scalp.
[0046] By setting the apical tube 8, the length of the extended hole-reducing needle tube 25 can be limited, thereby ensuring that the depth of the inserted hole-reducing needle tube 25 into the patient's scalp remains consistent, which can improve the hair follicle growth effect.
[0047] Meanwhile, the apical tube 8 can be set to multiple different lengths. By changing the apical tube 8 to a suitable length, it is convenient to extend the pore-expanding needle tube 25 out of the apical tube 8 to make adaptive adjustments when different hair follicles need to be implanted at different depths.
[0048] While the first turntable 10 rotates, it can drive the first fixed rod 11 to move synchronously. At the same time, because the first fixed rod 11 and the second fixed rod 16 are symmetrically arranged, when the second fixed rod 16 drives the second connecting plate 17 to move upward, the first fixed rod 11 drives the first connecting plate 12 to move downward.
[0049] This allows the first connecting plate 12 to move downwards while the second connecting plate 17 moves upwards to retract the movable ring 18 and the bottom expanding needle tube 25. This also causes the push needle 13 to move downwards inside the expanding needle tube 25, pushing the hair follicles inside the expanding needle tube 25 out of the expanding needle tube 25. This also allows the push needle 13 to be pushed downwards at the bottom while the expanding needle tube 25 is being retracted, making it easier to push the hair follicles into the wound inside where the expanding needle tube 25 is inserted, thereby improving the hair follicle growth effect.
[0050] When the bottom of the enlarging needle tube 25 becomes dull after being inserted for a long time and affects the operation and needs to be replaced, the pen tip 7 can be rotated and the pen tip 7 and the top tube 8 can be disengaged from the bottom of the pen body 1.
[0051] Then, by rotating the needle seat 24, the needle seat 24 and the enlarging needle tube 25 can be disengaged from the bottom of the movable ring 18, and then the new needle seat 24 and the enlarging needle tube 25 can be rotated and reconnected to the outside of the bottom of the movable ring 18.
[0052] The pen tip 7 and the top tube 8 are then rotatably connected to the outer bottom of the pen body 1, which allows for easy replacement of the needle seat 24 and the enlarging needle tube 25. At the same time, the rotatable connection between the top tube 8 and the bottom of the pen tip 7 allows the first reserved groove on the top tube 8 to be adjusted to the position corresponding to the second reserved groove on the enlarging needle tube 25, making it easier to place the hair follicle into the inside of the enlarging needle tube 25 during the implantation process.
[0053] All the motors mentioned above are motors with power-off self-locking capability, such as servo motors.
