Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a biomimetic microneedle continuous hair transplant system. Background Technology

[0002] Because current hair transplant systems use needles with relatively high puncture force, and the angle of the implanted hair follicles differs from the normal growth direction of hair follicles, traditional needles cause significant pain during surgery and result in poor implantation outcomes due to the misalignment of the implanted follicles. Traditional hair transplant systems use a "clamp-like" method to store hair follicles internally, requiring pauses in the procedure for follicle replacement, increasing surgery time and patient fatigue. Finally, traditional hair transplant systems employ a single "injection" method, which increases patient pain and the risk of mechanical damage.

[0003] To address the above problems, this invention presents a novel biomimetic microneedle-based continuous hair transplant system. The microneedles utilize a biomimetic structure resembling a snake's tooth to ensure that the implanted hair follicles follow the same direction as normally growing follicles. Simultaneously, the microneedles' outline is designed to resemble a bee sting, effectively reducing puncture force and patient pain. Follicle extraction employs an air pump and piping system. The air pump draws the follicles into the system through the piping; once a sensor detects a follicle, the air pump stops, and the motor activates to push it in. Based on this, this invention proposes a biomimetic microneedle continuous hair transplant system. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a biomimetic microneedle continuous hair transplant system. The microneedles of this system adopt a biomimetic structural design inspired by snake teeth and bee stings, effectively reducing puncture force and patient pain. Furthermore, the system uses a motor and lead screws with different pitches at both ends to drive the needle tip to pierce the skin and to drive the pusher to push the hair follicle in. Hair follicle extraction utilizes an air pump pipeline device. The air pump draws the hair follicle into the system through the pipeline. Once a sensor detects the hair follicle, the air pump stops and the motor starts to push it in.

[0005] To solve the above-mentioned technical problems, the present invention achieves its objective as follows: The present invention relates to a biomimetic microneedle continuous hair transplant system, comprising an axially extending outer shell, a power head that moves axially relative to the outer shell at one end, a hair follicle supply channel extending axially through the power head, a dual-screw composite seat and a motor for controlling the rotation of the dual-screw composite seat within the outer shell, the dual-screw composite seat comprising a seat body, a first screw and a second screw with unequal pitch at one end of the seat body, a first screw nut threaded onto the first screw, a second screw nut threaded onto the second screw, the second screw nut being connected to the power head, a push rod extending into the hair follicle supply channel on the first screw nut, and a hollow implantation needle extending axially through the power head, the rear end of the hollow implantation needle being connected to the front end of the hair follicle supply channel.

[0006] The invention is further configured such that: the power head is connected to a first connecting pipe and a second connecting pipe communicating with the hair follicle supply channel; the second connecting pipe extends radially along the power head; an air pump is provided inside the housing; a third connecting pipe extending to the outside of the housing is connected to the air inlet of the air pump; a fourth connecting pipe is provided on the third connecting pipe and arranged coaxially with the second connecting pipe; the opening of the fourth connecting pipe is abutted against the opening of the second connecting pipe; and a fifth connecting pipe is connected to the first connecting pipe.

[0007] The present invention is further configured such that the fifth connecting tube is provided with a handle.

[0008] The present invention is further configured such that the opening of the fifth connecting pipe has a flared structure.

[0009] The present invention is further configured such that: a sensor is embedded in the power head to sense the position of hair follicles in the hair follicle supply channel.

[0010] The invention is further configured such that: the power head includes a fixed base and a movable head; the movable head is axially inserted into the fixed base; the hollow needle is inserted into the movable head; a driven gear coaxially arranged on the movable head is rotatably connected to the movable head; a drive gear rotatably connected to the upper end of the fixed base is disengaged from the driven gear; the drive gear extends out of the side of the fixed base; a strip-shaped hole extending tangentially is provided on the drive gear; an adjusting column is slidably connected within the strip-shaped hole; a closed-ring groove is provided on the inner wall of the fixed base; a locking block that moves radially is embedded in the groove; the locking block is connected to the adjusting column; when the locking block leaves the groove, the movable head can separate along the axial direction of the fixed base.

[0011] The present invention is further configured such that: the end face of the drive gear facing the movable head is circumferentially arranged with a first gear groove and a second gear groove, and a ball-head plunger is embedded in the movable head, the ball head of the ball-head plunger being embedded in the first gear groove or the second gear groove.

[0012] The invention is further configured such that the hollow implanted needle is shaped like a snake's fang or a bee's stinger.

[0013] In summary, the present invention has the following beneficial effects:

[0014] 1. Personalization: Due to its modular design, the needle base of this invention is detachable, allowing for needle replacement based on the individual patient's skin and hair follicle condition. This caters to the surgical requirements of patients with varying skin thickness and hair follicle size, and the ability to change needles fulfills the patient's individual needs.

[0015] 2. Functional Optimization: By combining an air pump, motor, and sensors, continuous and rapid extraction and implantation of hair follicles are achieved. This improves the efficiency of hair transplantation and reduces surgery time. It also reduces fatigue for both patients and doctors caused by prolonged surgery. This invention utilizes a biomimetic microneedle structure, which continuously reduces the puncture force on the skin while maintaining the original growth direction of the hair follicles, thus reducing patient pain.

[0016] 3. Wide range of applications: This system can be used not only for hair follicle implantation, but also for hair follicle extraction from the scalp and for repairing skin scars. It can also be modified by replacing the air pump with a water pump to enable functions such as tattooing and drug delivery. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are merely for further illustrating the features and advantages of the present invention, and not for limiting the scope of the patent claims of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0027] Example 1

[0028] See Figures 1 to 5 As shown, the biomimetic microneedle continuous hair transplant system involved in this embodiment includes a shell 1 extending along the axial direction. One end of the shell 1 is provided with a power head 2 that moves axially relative to it. The power head 2 has a hair follicle supply channel 3 that runs through the front and back along the axial direction. The shell 1 is provided with a double screw composite seat and a motor 4 that controls the rotation of the double screw composite seat. The double screw composite seat includes a seat body 5. One end of the seat body 5 is provided with a first screw 6 and a second screw 7 with different pitches. A first screw nut 8 is threadedly connected to the first screw 6, and a second screw nut 9 is threadedly connected to the second screw 7. The second screw nut 9 is connected to the power head 2. The first screw nut 8 is provided with a top rod 10 that extends into the hair follicle supply channel. The power head 2 is provided with a hollow implant needle 11 that runs through the front and back. The rear end of the hollow implant needle 11 is connected to the front end of the hair follicle supply channel 3.

[0029] Furthermore, the power head 2 is connected to a first connecting pipe 12 and a second connecting pipe 13 that communicate with the hair follicle supply channel. The second connecting pipe 13 extends radially along the power head 2. An air pump 14 is provided inside the outer casing 1. A third connecting pipe 15 extending to the outside of the outer casing is connected to the air inlet of the air pump 14. A fourth connecting pipe 16 is provided on the third connecting pipe 15, which is coaxially arranged with the second connecting pipe. The opening of the fourth connecting pipe 16 is abutted against the opening of the second connecting pipe 13. A fifth connecting pipe 17 is connected to the first connecting pipe 12. The third and fourth connecting pipes are fixed tubes, while the fifth connecting pipe is a bent, irregular tube.

[0030] Furthermore, the fifth connecting pipe 17 is provided with a handle 18.

[0031] Furthermore, the opening of the fifth connecting pipe 17 has a flared structure.

[0032] Furthermore, the power head 2 is embedded with a sensor 19 that senses the position of the hair follicles in the hair follicle supply channel.

[0033] In this embodiment, the air pump 14 is turned on via an external switch. The air pump 14 is connected to the hair follicle extraction tube (i.e., the fifth connecting tube 17) through external and internal pipes. Holding the handle 18 of the hair follicle extraction tube, the nozzle is aligned with the hair follicle, drawing it into the internal pipe (i.e., the hair follicle supply channel 3). After the sensor in the internal pipe detects the hair follicle, it transmits a signal to start the motor 4 and stop the air pump 14. The motor 4 drives the rotating lead screw (including the first lead screw 6 and the second lead screw 7) to rotate. The rotating lead screw uses different pitches at both ends to simultaneously push the needle and hair follicle into the designated position inside the skin via the connected motion connecting rod (i.e., the connected power head 2) and the hair follicle push rod (i.e., the push rod 10). After the motor 4 has rotated a certain number of times, it automatically rotates in the opposite direction, simultaneously driving the push rod and the needle out of the skin. After rotating a specified number of times, the motor automatically stops and the air pump starts. The next cycle begins, with one hair follicle implanted per cycle.

[0034] The working principle is as follows: An air pump draws hair follicles into the internal channel. A motor, combined with lead screws of varying pitches, simultaneously achieves two different displacements. Once the needle is inserted into the skin, the hair follicle is delivered to the designated location. The needle employs a biomimetic design to reduce puncture force while ensuring the implanted hair follicle follows the same direction as naturally growing hair follicles.

[0035] The handle 18 is designed for gripping, making it easy to pick up the hair follicle extraction tube.

[0036] In particular, by setting the opening of the fifth connecting tube 17 as a flared structure, it is convenient to capture hair follicles.

[0037] Example 2

[0038] See Figures 6 to 8As shown, this embodiment of the biomimetic microneedle continuous hair transplant system, based on embodiment 1, further comprises the following configuration: the power head 2 includes a fixed base 201 and a movable head 202. The movable head 202 is axially inserted into the fixed base 201, and the hollow implantation needle 11 is inserted into the movable head 202. A driven gear 203 is rotatably connected to the movable head 202 and arranged coaxially therewith. A drive gear 204 rotatably connected to the upper end of the fixed base is disengaged from the driven gear 203. The drive gear 204 extends out of the fixed base. On the side of the fixed base 201, the drive gear 204 has a strip-shaped hole 205 extending tangentially, and an adjusting column 206 is slidably connected in the strip-shaped hole 205. The inner wall of the fixed base 201 has a closed ring-shaped groove 207, and a locking block 208 that moves radially is embedded in the groove 207. The locking block 208 is slidably connected to the movable head 202 and is connected to the adjusting column 206. When the locking block 208 leaves the groove 207, the movable head 202 can be separated along the axial direction of the fixed base 201.

[0039] Furthermore, the drive gear 204 has a first gear groove (not shown) and a second gear groove (not shown) arranged circumferentially on the end face facing the movable head, and a ball head plunger (not shown) is embedded in the movable head 202, with the ball head of the ball head plunger embedded in the first gear groove or the second gear groove.

[0040] In this embodiment, by manually turning the drive gear 204, the driven gear 203 rotates through transmission, causing the adjusting column 206 to move within the slot 205, causing the locking block 208 to retract and be pulled out from the slot 207. At this time, the power head 2 can be removed from the fixed seat 201 along the axial direction for replacement or maintenance operations between different models.

[0041] Example 3

[0042] See Figures 1 to 8 As shown, the biomimetic microneedle continuous hair transplant system involved in this embodiment is further configured, based on embodiment 1, that the hollow implant needle 11 is shaped like a snake's fang or a bee's sting.

[0043] In this embodiment, by setting the hollow implanted needle 11 to the shape of a snake's fang or a bee's sting, the pain of piercing the skin is reduced.

[0044] The biomimetic microneedle continuous hair transplant system disclosed in this invention features microneedles with a biomimetic structure design inspired by snake teeth and bee stings, effectively reducing puncture force and patient pain. The system utilizes a motor and lead screws with different pitches at both ends to drive the needle tip into the skin and to drive the pusher to push the hair follicle in. Follicle extraction employs an air pump pipeline device; the air pump draws the hair follicle into the system through the pipeline, and once a sensor detects the follicle, the air pump stops and the motor starts to push it in. The system is functionally complete and highly practical.
