Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a hair extraction system and hair extraction method. Background Technology

[0002] Hair transplantation is a common treatment for hair loss. The hair transplantation process generally involves three steps: hair extraction, follicle separation, and transplantation. Currently, there are two main methods for hair extraction: manual extraction and mechanical extraction.

[0003] Manual hair extraction requires manual operation of the extraction instrument. This method is unaffected by hair length and therefore does not require shaving, but it is less efficient. Mechanical hair extraction typically involves rotating a circular cutting device around the hair follicle, loosening the follicle by cutting the surrounding tissue along a circular cutting path. The follicle is then removed with tweezers and loaded into the hair transplant device. This circular cutting method requires shaving, and its large radial dimension of the circular cutting path can easily affect adjacent hair follicles during the cutting process. Furthermore, the uneven deformation of the surrounding tissue during the circular cutting process can easily sever or damage the hair follicle.

[0004] The above hair retrieval methods cannot simultaneously meet the requirements of hair retrieval efficiency and hair retrieval without shaving the head.

[0005] Therefore, a hair extraction system and method are needed to simultaneously meet the requirements of hair extraction efficiency and hair extraction without shaving the hair. Summary of the Invention

[0006] This invention provides a hair extraction system and method. The device can extract hair without shaving, and the extraction efficiency is high without damaging the hair follicles.

[0007] The sending and receiving system includes: a hair fixing module and a hair receiving module;

[0008] The hair-fixing module is used to fix the hair and expose the hair follicles to be extracted;

[0009] The hair extraction module includes a hair extraction needle and a first driving member. The hair extraction needle has a hollow hair extraction cavity and an inner wall with a receiving groove. The receiving groove is used to cause the fat layer of the hair follicle to move into the receiving groove when the hair extraction needle cuts the hair follicle to be extracted. The first driving member is used to drive the hair extraction needle to move along the axial direction of the hair extraction needle so as to simultaneously cut the tissue around the hair follicle to be extracted and remove the hair follicle.

[0010] Optionally, the hair-retrieving needle has a first groove, which extends from the outer wall of the hair-retrieving needle to the inner wall of the hair-retrieving cavity, and the first groove is connected to the distal end of the hair-retrieving needle.

[0011] Optionally, the distal end of the hair-retrieving needle has a plurality of blades protruding along the axial direction of the hair-retrieving needle, and each blade is spaced apart along the circumference of the hair-retrieving needle, and the first groove connects to the space between two adjacent blades.

[0012] Optionally, the hair extraction module further includes a positive pressure device, which has a fluid outlet connected to the hair extraction chamber to increase the pressure inside the hair extraction chamber.

[0013] Optionally, the hair-retrieving module further includes a second driving member and a sealing tube. The sealing tube is sleeved on the hair-retrieving needle and is slidably sealed with the hair-retrieving needle along the axial direction of the hair-retrieving needle. The second driving member is used to drive the sealing tube to move along the axial direction of the hair-retrieving needle.

[0014] Optionally, the hair extraction module further includes a base and a guide rod. The hair extraction needle is fixed to the distal end of the guide rod, and the guide rod extends along the axial direction of the hair extraction needle. The guide rod is movably mounted on the base along the axial direction of the hair extraction needle. The first driving member is used to drive the guide rod to move along the axial direction of the hair extraction needle. The guide rod has a channel, one end of which communicates with the hair extraction cavity, and the other end of which is used to introduce fluid to increase the pressure in the hair extraction cavity.

[0015] Optionally, the hair-taking module further includes a third driving component, which is used to drive the base to move in order to fine-tune the position of the hair-taking needle.

[0016] Optionally, the hair extraction module further includes an illumination device disposed on the base for illuminating the location where hair is to be extracted; and / or, the hair extraction module further includes an image acquisition device disposed on the base for acquiring images of the location where hair is to be extracted, so as to identify hair follicles and determine the location of the hair follicles to be extracted.

[0017] Optionally, the hair retrieval module further includes a robotic arm, on which the hair retrieval needle is mounted. The robotic arm is used to drive the hair retrieval needle to change its orientation to align with the position to be retrieved.

[0018] Optionally, the hair-fixing module includes a first hair clip and a second hair clip. The first hair clip is used to fix the hair at the position to be removed in the forward direction along a first direction, and the second hair clip is used to fix the hair at the position to be removed in the reverse direction along the first direction, so that the hair follicle at the position to be removed is exposed between the first hair clip and the second hair clip.

[0019] Optionally, the hair-fixing module further includes a first hair-fixing frame, which is connected to the first hair clip. The first hair-fixing frame is provided with a hair-fixing groove for placing the hair strands of the hair follicles to be extracted.

[0020] Optionally, the hair-fixing module further includes a second hair-fixing frame, which is used to fit against the first hair-fixing frame and cover the hair-fixing groove, so that the hair strands placed in the hair-fixing groove are confined within the hair-fixing groove.

[0021] Optionally, the hair retrieval system further includes a hair storage module, which includes a hair storage base and a hair storage hole. The hair storage hole is used for inserting the hair retrieval needle after hair retrieval to place the retrieved hair follicles into the hair storage hole.

[0022] Optionally, the inner wall of the launcher is provided with a second slot, which extends from the inner wall of the launcher to the outer wall of the launcher, and the second slot is connected to one end of the launch hole.

[0023] Optionally, the power storage module further includes a blocker, the power storage hole is a through hole opened on the power storage base, one end of the power storage hole is open, the blocker blocks the other end of the power storage hole, and the blocker is provided with mesh holes to allow air to circulate at the other end of the power storage hole.

[0024] The present invention also provides a method for receiving and sending, comprising the following steps:

[0025] Hair fixing: securing the hair and exposing the hair follicles to be extracted;

[0026] Hair extraction: Drive the hair extraction needle to advance along the axial direction of the hair extraction needle, so that the hair extraction needle penetrates into the tissue surrounding the hair follicle to be extracted, and so that the hair follicle to be extracted is located in the hair extraction cavity; after the hair extraction needle penetrates into the tissue to a set depth range, the fat layer of the hair follicle to be extracted peristalts into the receiving groove, the advance stops, and the hair extraction needle is driven to retract to extract the hair follicle to be extracted;

[0027] Hair removal follicle: Increase the pressure inside the hair extraction cavity, causing the hair follicle inside the hair extraction cavity to detach from the hair extraction cavity.

[0028] This configuration allows the hair extraction system to extract hair without shaving. During extraction, the extraction chamber allows the extraction needle to cut the hair follicle by advancing axially. The entire follicle is located within the extraction chamber, eliminating the need for circular cutting around it. This cutting method avoids damaging surrounding follicles and prevents damage caused by uneven deformation of surrounding tissue during circular cutting. The receiving groove allows the fatty tissue at the root of the follicle to peristalt and fill the groove when the extraction needle penetrates the tissue, anchoring the follicle within the extraction chamber. The needle can then be withdrawn to remove the follicle. This significantly improves extraction efficiency and reduces costs. In summary, this hair extraction system simultaneously meets the requirements of high extraction efficiency and non-shaving extraction, while minimizing damage to surrounding and target follicles during the extraction process.

[0053] The following detailed description of the delivery and retrieval system proposed in this invention, in conjunction with the accompanying drawings and specific embodiments, will further clarify the advantages and features of the invention. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the embodiments of the invention.

[0054] In this invention, "proximal" and "distal" refer to the relative orientation, position, and direction of the components or actions relative to each other from the perspective of the doctor using the product. Although "proximal" and "distal" are not restrictive, "distal" usually refers to the end that first enters the patient's body, and "proximal" usually refers to the opposite end of "distal".

[0055] In this invention, "outer diameter" and "inner diameter" refer to the diameter of a circular structure, while for a non-circular structure, the inner diameter refers to the diameter of its inscribed circle and the outer diameter refers to the diameter of its circumscribed circle. "Axial direction" refers to the direction of the central axis of a cylindrical rod, while for a non-cylindrical rod, the axial direction refers to the length direction of the rod.

[0056] As used in this invention, the singular forms “a,” “an,” and “the” include plural objects; the term “or” is generally used to mean “and / or”; the term “a number” is generally used to mean “at least one”; and the term “at least two” is generally used to mean “two or more”. Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with “first,” “second,” or “third” may explicitly or implicitly include one or at least two of that feature. Additionally, as used in this invention, “installed,” “connected,” “joined,” and “set” on one element by another should be interpreted broadly, generally indicating only a connection, coupling, mating, or transmission relationship between the two elements, which can be direct or indirect through an intermediate element. They should not be construed as indicating or implying a spatial positional relationship between the two elements, i.e., one element can be located inside, outside, above, below, or to one side of another element, unless otherwise explicitly stated. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances. Furthermore, directional terms such as above, below, up, down, upward, downward, left, right, etc., are used relative to exemplary embodiments as shown in the figures, with upward or up direction pointing towards the top of the corresponding figure, and downward or down direction pointing towards the bottom of the corresponding figure.

[0057] This embodiment provides a transmission retrieval system, including: a fixed transmission module 100, a transmission retrieval module 200, and a transmission storage module 300.

[0058] Please refer to Figure 1 and Figure 2As shown, the target object 400 sits in a designated position with its head fixed. The hair fixing module 100 fixes the hair at the location where hair is to be extracted, exposing the hair follicles. The hair extraction module 200 extracts the hair follicles and places them in the hair storage module 300. The hair extraction module 200 can be mounted on a workbench 500, which has casters at the bottom for easy movement. A display screen 600 is also provided on the workbench 500 for image display.

[0059] Please refer to the following for the structure and usage of the fixed-mode module 100. Figure 3 and Figure 4 As shown.

[0060] The hair-fixing module 100 includes a first hair clip 110, a second hair clip 120, a first hair-fixing frame 130, and a second hair-fixing frame 140;

[0061] Please refer to Figure 3 As shown, the first hair clip 110, the second hair clip 120, the first hair holder 130, and the second hair holder 140 are all arc-shaped structures. The first hair clip 110 and the second hair clip 120 are fastened to the head. The first hair clip 110 and the second hair clip 120 have comb teeth to facilitate fixing the hair. The two ends of the first hair holder 130 are rotatably engaged with the two ends of the first hair clip 110, and the two ends of the second hair holder 140 are rotatably engaged with the two ends of the first hair holder 130.

[0062] Please combine Figure 4 As shown, the first hairpin 110 is used to fix the hair at the location to be extracted along the first direction a, and the second hairpin 120 is used to fix the hair at the location to be extracted along the first direction a. The first hairpin 110 and the second hairpin 120 comb the hair on both sides of the location to be extracted along the first direction a, pressing the hair down to meet the scalp, so that the area b between the first hairpin 110 and the second hairpin 120 is exposed, thereby exposing the hair follicles to be extracted in area b without obstructing the camera and the needle insertion direction. The first direction a can be determined based on actual usage requirements, and the positive and negative directions of the first direction a are two directions along the first direction a.

[0063] Please continue to refer to this. Figure 3 and Figure 4As shown, the first hair-fixing frame 130 is provided with a hair-fixing groove 131, which is used to place the hair strands to be extracted from the hair follicles. When the first hair clip 110, the second hair clip 120, and the first hair-fixing frame 130 are in a hair-fixing state, the comb teeth on the first hair clip 110 and the second hair clip 120, as well as the hair-fixing groove 131, all extend along the first direction a. The second hair-fixing frame 140 can rotate relative to the first hair-fixing frame 130. During the rotation of the second hair-fixing frame 140, it can move away from the hair-fixing groove 131 to open the hair-fixing groove 131, or it can move close to the hair-fixing groove 131 and fit against the first hair-fixing frame 130, covering the hair-fixing groove 131.

[0064] After the first hairpin 110 and the second hairpin 120 have secured the hair, the hair strands from the hair follicle to be extracted are placed in the hair-fixing groove 131, and the second hair-fixing frame 140 covers the hair-fixing groove 131, thus restricting the hair strands within the hair-fixing groove 131. Here, "fixed" means that the hair strands are restricted in their movement within the hair-fixing groove 131, not that they are permanently fixed. With the hair strands from the hair follicle to be extracted confined within the hair-fixing groove 131, there is sufficient height allowance between the hair-fixing groove 131 and the hair follicle to be extracted. After the hair follicle is removed, the hair strands can be pulled out of the hair-fixing groove 131. The first hair-fixing frame 130 is rotatable relative to the first hairpin 110, allowing adjustment of the hair strands fixed in the hair-fixing groove 131 so that the hair strands are straightened, facilitating subsequent hair extraction.

[0065] In other alternative embodiments, the second hair holder 140 may not be provided, and an elastic material, such as rubber filling, may be provided in the hair holding groove 131. This allows the hair strands placed in the hair holding groove 131 to be elastically squeezed by the elastic material to confine the hair strands within the hair holding groove 131. Moreover, the hair strands can be pulled out of the hair holding groove 131 by tension without being damaged.

[0066] In this embodiment, the first hair clip 110, the first hair holder 130, and the second hair holder 140 are configured as a whole, while the second hair clip 120 is an independent structure. In other alternative embodiments, the second hair clip 120 can be connected to the first hair clip 110 to form a whole. Moreover, in other alternative embodiments, the first hair clip 110, the second hair clip 120, the first hair holder 130, and the second hair holder 140 can be configured with other structural forms, such as clamping structures similar to tweezers, which will not be described in detail here.

[0067] For the structure of the transmit / receive module 200, please refer to [reference needed]. Figures 5 to 10 As shown.

[0068] The hair extraction module 200 includes a hair extraction needle 210, a first driving component 220, and a robotic arm 280. The hair extraction needle 210 is mounted on the robotic arm 280, which drives the needle to change its orientation to align with the position to be extracted. In this embodiment, the specific structure of the robotic arm 280 is not limited. Based on the actual usage conditions and the required degrees of freedom for the orientation and position changes of the hair extraction needle 210, existing three-degree-of-freedom, four-degree-of-freedom, or more-degree-of-freedom robotic arms can be adaptively selected. By adjusting the orientation of the robotic arm 280, the tip of the hair extraction needle 210 is aligned with the hair follicle to be extracted.

[0069] Please refer to Figures 6 to 8 As shown, the hair extraction needle 210 has a hollow hair extraction cavity 211, and the inner wall of the hair extraction needle 210 is provided with a receiving groove 212. The receiving groove 212 is used to make the fat layer of the hair follicle to be extracted move into the receiving groove 212 when the hair extraction needle 210 cuts the hair follicle to be extracted. The first driving member 220 is used to drive the hair extraction needle 210 to move along the axial direction of the hair extraction needle 210. The hair extraction needle 210 has a feeding motion and a retraction motion along the axial direction. During the feeding motion, the hair extraction needle 210 pierces into the tissue around the hair follicle to be extracted, and the hair follicle to be extracted is anchored in the hair extraction cavity 211. During the retraction motion, the hair extraction needle 210 retracts to extract the hair follicle.

[0070] The hair extraction needle 210 has a first groove 213, which extends from the outer wall of the hair extraction needle 210 to the inner wall of the hair extraction cavity 211, and connects to the distal end of the hair extraction needle 210. In this embodiment, the first groove 213 extends along the axial direction of the hair extraction needle 210 to facilitate the insertion of the hair strands from the hair follicles to be extracted. In other alternative embodiments, the first groove 213 may be set at an angle relative to the axial direction of the hair extraction needle 210, depending on the needs of use; this will not be elaborated here.

[0071] When the hair extraction needle 210 is aligned with the hair follicle to be extracted, it is ready to be inserted into the tissue. At this time, the hair strand of the hair follicle to be extracted has been fixed in the hair-fixing groove 131. The first groove 213 of the hair extraction needle 210 should be aligned with the hair strand of the hair follicle to be extracted, so that during the insertion process, the hair strand passes from the distal end of the hair extraction needle 210 into the first groove 213, ensuring that the hair strand corresponding to the hair follicle to be extracted is not damaged during the insertion process. The hair extraction needle 210 is driven to advance by the first driving member 220, so that the hair extraction needle 210 is inserted into the tissue surrounding the hair follicle to be extracted, and the entire hair follicle to be extracted is located in the extraction cavity 211. Moreover, the fatty tissue at the root of the hair follicle to be extracted will peristaltically fill the receiving groove 212 to anchor the hair follicle to be extracted in the extraction cavity 211. At this time, the hair extraction needle 210 retracts to extract the hair follicle to be extracted.

[0072] This hair extraction system allows for hair extraction without shaving. During extraction, the first groove 213 avoids damaging the hair strands corresponding to the hair follicles. The extraction chamber 211 allows the extraction needle 210 to cut the hair follicle by axial insertion. The entire follicle is located within the extraction chamber 211, eliminating the need for circumferential cutting. This cutting method avoids affecting surrounding follicles and prevents damage during circumferential cutting due to uneven deformation of surrounding tissue. The receiving groove 212 allows the adipose tissue at the root of the hair follicle to peristalt and fill the receiving groove 212 when the extraction needle 210 penetrates the tissue, anchoring the follicle within the extraction chamber 211. The extraction needle 210 can then be withdrawn to remove the follicle. This effectively improves extraction efficiency and reduces extraction costs. In summary, this hair extraction system simultaneously meets the requirements of high hair extraction efficiency and hair extraction without shaving, and improves the phenomenon of damage to surrounding hair follicles and the hair follicles to be extracted during the hair extraction process.

[0073] Furthermore, to ensure that more fat tissue at the root of the hair follicle is filled into the receiving groove 212 through peristalsis, thus forming a stable anchoring effect on the hair follicle, in this embodiment, the receiving groove 212 extends from the inner wall of the hair extraction cavity 211 to the outer wall of the hair extraction needle 210. The receiving groove 212 has an overall waist-shaped hole structure, and the length direction of the receiving groove 212 is consistent with the axial direction of the hair extraction needle 210. Therefore, in actual use, some tissue will fill the receiving groove 212 and overflow outside the hair extraction cavity 211, improving the anchoring effect on the hair follicle and facilitating its extraction. In other alternative embodiments, the receiving groove 212 may not extend to the outer wall of the hair extraction needle 210. In this case, increasing the air pressure inside the hair extraction cavity 211 facilitates the removal of fat tissue from the receiving groove 212 when the hair follicle detaches. Additionally, in this embodiment, two receiving grooves 212 are arranged opposite each other along a radial direction of the hair extraction needle 210. In other alternative embodiments, more receiving slots 212 may be provided, with each receiving slot 212 distributed circumferentially along the take-up needle 210 to ensure a better anchoring effect.

[0074] Furthermore, the distal end of the hair-retrieving needle 210 has a plurality of blades 214 protruding along the axial direction of the hair-retrieving needle 210, and each blade 214 is spaced apart along the circumferential direction of the hair-retrieving needle 210.

[0075] Please refer to Figure 6 and Figure 7As shown, in one embodiment of the cutting edge 214, a sharp cutting edge 214 is formed after cutting at the distal outer wall of the hair-retrieving needle 210. Two cutting edges 214 are provided, each approximately semi-circular, with a V-shaped groove between adjacent cutting edges 214. A first groove 213 connects to the V-shaped groove between the two cutting edges 214. This structure facilitates puncture, and the V-shaped groove guides the hair strands from the hair follicles to be retrieved into the first groove 213.

[0076] Please refer to Figure 8 As shown, another embodiment of the cutting edge 214 is provided. In this embodiment, four cutting edges 214 are provided. The cutting edges 214 are roughly triangular and evenly distributed along the circumference of the hair-taking needle 210.

[0077] In other alternative embodiments, the number and shape of the cutting edges 214 can be adapted to the actual needs of use.

[0078] Please refer to Figure 9 and Figure 10 As shown, the hair extraction module 200 further includes a positive pressure device 230, which has a fluid outlet connected to the hair extraction chamber 211 to increase the pressure inside the hair extraction chamber 211. The pressure inside the hair extraction chamber 211 can be either pneumatic or hydraulic. For example, when the positive pressure device 230 fills the hair extraction chamber 211 with gas, the pneumatic pressure inside the hair extraction chamber 211 is increased; when the positive pressure device 230 fills the hair extraction chamber 211 with liquid, the hydraulic pressure inside the hair extraction chamber 211 is increased.

[0079] In this embodiment, the positive pressure device 230 includes a connector and a cylinder, wherein Figure 9 and Figure 10 Only the connector of the positive pressure device is shown. This connector serves as a fluid outlet connected to an external cylinder to inflate the hair extraction chamber 211, increasing the air pressure and allowing the hair follicle to detach from the extraction chamber 211 and be placed in a designated position. In other alternative embodiments, the positive pressure device 230 can also use hydraulic pressure to increase the pressure within the extraction chamber 211, which will not be elaborated here. The positive pressure device 230 facilitates automatic hair follicle removal and ensures that hair follicle detachment is achieved without contact, thus protecting the hair follicle.

[0080] Furthermore, the take-up module 200 also includes a base 240 and a guide rod 250. The take-up needle 210 is fixed to the distal end of the guide rod 250. The guide rod 250 extends along the axial direction of the take-up needle 210 and is movably mounted on the base 240 along the axial direction of the take-up needle 210. The first driving member 220 is used to drive the guide rod 250 to move along the axial direction of the take-up needle 210.

[0081] Please refer to Figure 10As shown, this layout facilitates the overall structure. A channel 251 is provided within the guide rod 250, axially connecting to both ends of the guide rod 250. The hair-retrieving chamber 211 of the hair-retrieving needle 210 is connected from its distal end to its proximal end. The proximal end of the hair-retrieving needle 210 is connected to the distal end of the guide rod 250, and the proximal end of the hair-retrieving chamber 211 is connected to the distal end of the channel 251. The air outlet of the positive pressure device 230 is connected to the proximal end of the channel 251. The fluid medium introduced by the positive pressure device 230 enters the hair-retrieving chamber 211 through the channel 251, thereby increasing the pressure within the hair-retrieving chamber 211 to remove hair follicles. The guide rod 250 facilitates the overall structural layout of the hair-retrieving system.

[0082] Additionally, the base 240 has a hollow mounting cavity in its center. The guide rod 250 is slidably mounted within the mounting cavity of the base 240 along the axial direction of the take-up needle 210 via a linear bearing 293. A first driving member 220 is disposed on the base 240 and connected to the guide rod 250 to drive the guide rod 250 to move axially along the take-up needle 210. Further details can be found in the following references. Figure 10 As shown, the hair extraction module 200 also includes a second driving member 291 and a sealing tube 292. The sealing tube 292 is sleeved on the hair extraction needle 210 and slides and seals with the hair extraction needle 210 along the axial direction of the hair extraction needle 210. The second driving member 291 is used to drive the sealing tube 292 to move along the axial direction of the hair extraction needle 210.

[0083] Due to the through-hole structure of the receiving groove 212 and the first opening 213, if the positive pressure device 230 inflates the hair extraction chamber 211, the gas will leak from the receiving groove 212 and the first opening 213. Therefore, in this embodiment, a sealing tube 292 is added to open or close a portion of the receiving groove 212 and the first opening 213. When the sealing tube 292 slides axially along the hair extraction needle 210 toward its distal end, it will block a portion of the receiving groove 212 and the first opening 213. At this time, the positive pressure device 230 can increase the pressure in the hair extraction chamber 211 to remove hair follicles. When the sealing tube 292 slides axially along the hair extraction needle 210 toward its proximal end, it will open the receiving groove 212 and the first opening 213, allowing the hair extraction needle 210 to puncture and extract hair. In this embodiment, the first driving member 220 and the second driving member 291 are cylinders. In other alternative embodiments, the first driving member 220 and the second driving member 291 may also be linear motors or other known linear drive structures.

[0084] For further details, please refer to... Figure 9As shown, the hair-retrieving module 200 also includes a third drive unit 294. The base 240 is movably mounted at the end of the robotic arm 280. The third drive unit 294 is used to drive the base 240 to move relative to the robotic arm 280 to fine-tune the position of the hair-retrieving needle 210. The third drive unit 294 can be a linear drive module to drive the base 240 to move linearly. For example, the third drive unit 294 can be a linear motor, a hydraulic cylinder, a drive structure composed of a lead screw and nut pair, or other known linear drive structures. Before the hair-retrieving needle 210 punctures, the position of the hair-retrieving needle 210 can be fine-tuned by the third drive unit 294 so that the hair-retrieving needle 210 maintains a suitable distance from the position to be retrieved.

[0085] For further information, please refer to the following: Figure 10 As shown, the hair retrieval module 200 also includes an illumination device 260, which can be an LED or similar device. The illumination device 260 is mounted on the base 240 and illuminates the area where hair needs to be retrieved. The hair retrieval module 200 also includes an image acquisition device 270, which can be a binocular camera. The image acquisition device 270 is mounted on the base 240 and is used to acquire images of the area where hair needs to be retrieved, to identify hair follicles and determine their location. The image acquisition device 270 uploads the acquired images to an image recognition system for hair follicle identification and positioning. This allows the robotic arm to change its orientation so that the hair retrieval needle 210 is aligned with the hair follicle. The distance between the hair retrieval needle and the hair follicle can be finely adjusted to improve retrieval accuracy and achieve automatic hair retrieval. Simultaneously, the image acquisition device 270 can also identify the position of the hair retrieval needle 210, ensuring that the first groove 213 and the hair strand of the hair follicle are on the same straight line, so that the hair strand enters the first groove 213 during puncture.

[0086] In other alternative embodiments, the lighting device 260 and the image acquisition device 270 may be selectively configured based on usage requirements.

[0087] Please refer to the structure of the energy storage and transmission module 300. Figure 11 and Figure 12 As shown;

[0088] The hair storage module 300 can be placed on the workbench 500. The hair storage module 300 includes a hair storage base 310, which has hair storage holes 311 for inserting the hair extraction needle 210 after hair extraction to place the extracted hair follicles into the hair storage holes 311. The hair storage base 310 is elongated, and multiple hair storage holes 311 are arranged along the length of the hair storage base 310. Each hair storage hole 311 is connected to the upper end face of the hair storage base 310. After the hair extraction needle 210 has finished extracting hair, the robotic arm 280 drives the hair extraction needle 210 to pass through the upper end face of the hair storage base 310 and insert it into the hair storage hole 311. Then, the positive pressure device 230 increases the pressure inside the hair extraction cavity 211, causing the hair follicles to detach from the hair extraction cavity 211 and enter the hair storage hole 311 for storage.

[0089] Furthermore, the inner wall of the launch storage base 310 is provided with a second slot 312, which extends from the inner wall of the launch storage base 310 to the outer wall of the launch storage base 310, and the second slot 312 is connected to one end of the launch storage hole 311.

[0090] The second slot 312 extends axially along the hair storage hole 311. When the hair-retrieving needle 210 is inserted into the hair storage hole 311, the image acquisition device 270 can acquire an assembly image of the hair-retrieving needle 210 to ensure that the second slot 312 and the first slot 213 are radially aligned along the hair storage hole 311. Figure 12 As shown, when the hair follicle 700 is placed in the hair storage hole 311, the hair strand 710 of the hair follicle 700 enters the second groove 312, which facilitates the storage of long hair follicles.

[0091] Please continue to refer to the following: Figure 12 As shown, the hair follicle storage module 300 also includes a plug 320. The hair follicle storage hole 311 is a cylindrical through hole formed on the hair follicle storage base 310. One end of the hair follicle storage hole 311 is open, and the plug 320 plugs the other end of the hair follicle storage hole 311. The plug 320 is provided with mesh to allow air circulation at the other end of the hair follicle storage hole 311. The plug 320 can be a sponge, mesh, or other structures. The plug 320 ensures effective storage of hair follicles while also ensuring air circulation, facilitating hair follicle detachment, and effectively protecting hair follicles from airflow damage.

[0092] This embodiment also provides a method for receiving and sending data; please refer to [reference needed]. Figure 13 As shown, the specific steps include hair strengthening, hair extraction, and hair follicle removal:

[0093] Fixed hair: Please refer to Figure 14 As shown, the hair at the location to be extracted is fixed along the first direction in the forward direction, and the hair at the location to be extracted is fixed along the first direction in the reverse direction, thus securing the hair strands containing the hair follicles. By fixing the hair along the first direction in both the forward and reverse directions, the hair follicles at the location to be extracted are exposed; the hair strands containing the hair follicles are then fixed, with the specific hair-fixing method as follows. Figure 4 As shown, the hair is fixed in place by the first hair clip 110, the second hair clip 120, the first hair holder 130 and the second hair holder 140, which will not be described in detail here.

[0094] Pick-up and delivery: Please refer to Figure 15 As shown, the system is first started, the lighting device 260 is turned on for illumination, and the camera of the image acquisition device 270 is activated to acquire images to identify hair follicles and determine the location of the hair follicles to be extracted. Then, the robotic arm 280 is driven to move into position to adjust the position of the hair extraction needle 210. Finally, the position of the hair extraction needle 210 is finely adjusted by the third drive component 294 to maintain a suitable distance between the hair extraction needle 210 and the location where the hair is to be extracted. At this time, the camera of the image acquisition device 270 further acquires information to confirm the location of the hair follicle to be extracted, and drives the hair extraction needle 210 to advance along the axial direction of the hair extraction needle 210, so that the hair extraction needle 210 pierces into the tissue around the hair follicle to be extracted, and the hair follicle to be extracted is located in the hair extraction cavity 211. At the same time, when the hair extraction needle 210 pierces the tissue, the hair strand of the hair follicle to be extracted extends to the outside of the hair extraction cavity 211 through the first groove 213. The hair extraction needle 210 pierces into the tissue within a set depth range, which can be determined according to the actual working conditions. It should be ensured that within the set depth range, the position of the hair extraction needle 210 in the receiving groove 212 will penetrate into the fat layer of the hair follicle to be extracted, so that the fat layer of the hair follicle to be extracted peristalsis into the receiving groove 212, and then the feeding stops, and the hair extraction needle is driven to retract to extract the hair follicle to be extracted.

[0095] Hair follicle removal: First, seal the receiving groove 212 and at least a portion of the first groove opening 213. Specifically, the receiving groove 212 and the first groove opening 213 can be sealed by moving the sealing tube 292 to prevent air leakage. Insert the hair extraction needle 210 into the hair storage position. In this embodiment, the hair extraction needle 210 is inserted into the hair storage hole 311 of the hair storage module 300. Then, air is introduced into the hair extraction chamber 211 through the positive pressure device 230 to increase the pressure in the hair extraction chamber 211, so that the hair follicles in the hair extraction chamber 211 detach from the hair extraction chamber 211 and enter the hair storage hole 311 for storage.

[0096] Please refer to Figure 16 As shown, in the sending and receiving step, the sending and receiving path can be planned using the image acquired by the image acquisition device 270. In this embodiment, each sending and receiving path is a linear path c. After sending and receiving according to a linear path c, the sending and receiving is fixed again, and the next path is planned, and multiple linear sending and receiving paths are generated in sequence.

[0097] Through the above hair extraction steps, hair can be extracted without shaving, and the hair strands are not damaged during the extraction process. Furthermore, the extraction chamber 211 allows the extraction needle 210 to cut the hair follicle by axial straight insertion, eliminating the need for circular cutting around the follicle. This cutting method avoids affecting surrounding hair follicles and improves the situation where uneven deformation of the surrounding tissue during circular cutting damages the hair follicle to be extracted. It also improves extraction efficiency and reduces extraction costs. In summary, it simultaneously meets the requirements of efficient hair extraction and hair extraction without shaving, while minimizing damage to surrounding and target hair follicles during the extraction process.

[0098] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
