Description

Technical Field

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

[0002] Hair transplantation, also known as autologous hair transplantation, involves separating healthy hair follicles from the back of the head and transplanting them to balding areas such as the forehead or other areas of the body where hair has fallen out. This process ensures the integrity and survival rate of the transplanted hair, preserves its growth characteristics, and allows the hair to continue growing in the new transplant area.

[0003] Currently, hair transplant techniques include FUE (Follicular Unit Extraction) and FUT (Follicular Unit Transplantation). In recent years, with the obvious advantages of FUE and its gradual maturation, most patients have chosen FUE hair transplantation. Based on FUE, improvements have been made to the hair transplant needle technique, continuously optimizing the method to fully leverage its advantages such as wider applicability, faster wound healing, fewer complications, and smaller scars. Therefore, the majority of hair transplantation techniques on the market are still based on sampling FUE. In addition, depending on the different needs of patients, there are also shaving hair transplantation and non-shaving hair transplantation, among which non-shaving hair transplantation includes two types: short hair transplantation (2cm-3cm) and long hair transplantation (8cm-10cm).

[0004] In the FUE hair transplant method, regardless of whether the hair is shaved, the most crucial part is the preparation of the hair follicle transplant, and the key to the preparation of the hair follicle transplant lies in the extraction of hair follicles. Hair follicle extraction is mainly carried out using hair extraction needles. The integrity and efficiency of hair follicle extraction directly affect the effect and time of the surgery. Currently, the main hair follicle extraction equipment used is the electric hair extraction device, but the electric hair extraction device has the following defects and shortcomings:

[0005] 1. Electric hair extractors use rotating needles to cut and separate the scalp and hair follicles. However, there are significant drawbacks in the rotating cutting process. Because the needle is blunt, it relies on high-speed rotation to act as a cutting edge. However, at the moment of initial contact between the rotating needle and the scalp, friction will exist between the two, changing the angle and direction of the needle insertion. This can even cause a large deviation from the target hair follicle, thus greatly reducing the accuracy of hair extraction. Therefore, the operator needs to apply varying degrees of constant force with their hand to counteract the deflection of the needle and reduce the deviation in position, angle, and direction in order to ensure the integrity of hair extraction as much as possible.

[0006] 2. The needle of the electric hair extractor is blunt. Although high-speed rotation can cut, the hardness of the epidermal tissue varies from patient to patient. Some epidermal tissues are soft and easy to break, while others are hard and difficult to break. Therefore, even if the same hair extractor is used, the effect will be different for each person.

[0007] Third, the electric hair extractor is triggered by a foot pedal. The operator steps on the pedal to control the hair extractor to start. This requires perfect coordination of hands and feet, which is inconvenient to operate and prone to errors.

[0008] Fourth, the electric hair extraction device can only separate hair follicles and tissues. The extracted hair follicles still need to be grasped and removed by the doctor with special hair follicle tweezers. The grasped hair follicle tissue is easily damaged, which leads to the destruction of its structure that regulates hair growth, affecting the growth of hair follicles after hair transplantation, resulting in a lower survival rate and directly affecting the final hair transplant effect.

[0009] Fifth, in the process of hair transplantation without shaving the head, the difficulty of short hair extraction and long hair extraction is greater than that of hair extraction with shaving the head. For example, the hair extraction surgery takes longer, and long hair extraction is more likely to damage and cut hair follicles, affecting the overall integrity rate and survival rate.

[0010] There is currently no effective solution to the problems of electric hair extraction devices being difficult to operate, having low hair follicle survival rates, and having poor extraction results.

[0011] Therefore, based on years of experience and practice in related industries, the inventor proposes a hair extraction device and a hair transplant robot to overcome the shortcomings of existing technologies. Summary of the Invention

[0022] In a preferred embodiment of the present invention, a sensing device is provided on the first needle or on the end face of the first connector near the needle tip. When the sensing device comes into contact with the patient's skin, it controls the second needle to rotate and move towards the patient's skin. When the sensing device separates from the patient's skin, it controls the second needle to stop rotating and reset.

[0023] In a preferred embodiment of the present invention, the storage device has a first port, a second port, and a third port that are respectively connected to the storage cavity. The first port is used to communicate with the second channel, the second port is used to connect with the negative pressure device, and the third port is used to connect with the saline supply device.

[0024] In a preferred embodiment of the present invention, a filter device is provided in the storage cavity and located between the first port and the second port to reduce the hair follicle tissue being drawn out from the second port.

[0025] In a preferred embodiment of the present invention, a rotary drive mechanism is also included;

[0026] The rotary drive mechanism includes a first motor and a transmission assembly. The output shaft of the first motor is connected to the second needle through the transmission assembly, and the transmission assembly drives the second needle to rotate along its own central axis.

A negative pressure environment is formed within the storage cavity. The second needle is movably positioned within the first channel along its axial direction to form a double-needle structure. The second channel of the second needle is connected to the storage component. During hair extraction, the first and second needles work in tandem. When the tip of the first needle comes into contact with the patient's skin and is subjected to pressure, the second needle begins to move. The tip of the second needle moves to the bottom of the hair follicle tissue. The first needle ensures the stability of the extraction position and cuts the skin at the location of the hair follicle tissue. Then, the second needle separates and extracts the hair follicle tissue. The operation is simple and reduces the occurrence of hair follicle damage. The extracted hair follicle tissue is aspirated and stored in the storage cavity under negative pressure.

[0079] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0080] Implementation Method 1

[0081] like Figures 1 to 10 As shown, the present invention provides a hair extraction device, which includes a first needle 1, a second needle 2, and a storage component 5. The first needle 1 has a first channel and is used to anchor itself on the patient's skin and cut the skin at the location of the hair follicle tissue. The second needle 2 has a second channel and is movably disposed within the first channel along its axial direction. The second needle 2 is used to separate and extract the cut hair follicle tissue. The storage component 5 has a storage cavity 501, in which a negative pressure environment is formed. The storage cavity 501 is connected to the second channel. When the tip of the first needle 1 anchors and cuts the patient's skin, the tip of the second needle 2 moves to the bottom of the hair follicle tissue. The negative pressure environment within the storage cavity 501 allows the hair follicle tissue to be extracted and stored in the storage cavity 501.

[0082] In this invention, a first needle 1 with a first channel and a second needle 2 with a second channel are provided, along with a storage component 5 having a storage cavity 501 inside. A negative pressure environment is formed inside the storage cavity 501. During hair retrieval, the first needle 1 and the second needle 2 work together. When the needle tip of the first needle 1 comes into contact with the patient's skin and is subjected to pressure, the second needle 2 begins to move. The needle tip of the second needle 2 moves to the bottom of the hair follicle tissue. The first needle 1 ensures the stability of the hair retrieval position and cuts the skin at the location of the hair follicle tissue. Then, the second needle 2 separates and removes the hair follicle tissue. The operation is simple and reduces the occurrence of hair follicle damage. The removed hair follicle tissue is aspirated and stored in the storage cavity 501 under negative pressure. During the hair retrieval process, a sterile environment can be created in the storage cavity 501, and the storage component 5 can be adapted to different storage spaces according to the different hair lengths of the hair follicles, thereby meeting the needs of different hair transplant patients and ensuring the survival rate of hair follicles, thus improving the success rate of hair transplantation.

[0083] In an optional embodiment of the present invention, the second needle 2 is rotatably disposed within the first channel along its own central axis. When the tip of the second needle 2 moves toward the hair follicle tissue, the second needle 2 simultaneously rotates along its own central axis so that the tip of the second needle 2 can smoothly enter the patient's skin, thereby achieving the separation of the hair follicle tissue from the skin.

[0084] In an optional embodiment of the present invention, such as Figures 5 to 7 As shown, the first needle 1 is tubular, and its tip has multiple anchoring portions 101 evenly arranged circumferentially along the first needle 1. Each anchoring portion 101 has a pointed tip, and cutting blades 1011 are provided on both sides of the tip (i.e., the anchoring portion 101 is triangular, with one corner of the triangle being the pointed tip, and cutting blades 1011 on the two sides adjacent to the pointed tip). The anchoring portions 101 anchor the hair-retrieval device to the patient's skin and cut the skin. Before hair retrieval, the pointed tip of the anchoring portion 101 is inserted into the patient's scalp tissue to fix the hair-retrieval device, reducing the possibility of deviation during the process and increasing the accuracy of hair retrieval. Since the cutting blades 1011 are provided on both sides of the pointed tip, it facilitates cutting the skin, ensuring that the second needle 2 can directly enter the subcutaneous tissue, further reducing the possibility of deviation during the rotation and movement of the second needle 2. Preferably, three anchoring portions 101 are used to provide better stability.

[0085] Furthermore, such as Figure 5 , Figure 8 As shown, the second needle 2 is tubular. In the assembled state of the first needle 1 and the second needle 2, the second needle 2 is located within the first channel of the first needle 1, and the first needle 1 and the second needle 2 are matched (i.e., the first needle 1 and the second needle 2 are coaxial, and the outer wall of the first needle 1 is in contact with the inner wall of the second needle 2). The inner diameter of the second needle 2 (i.e., the diameter of the second channel) can be, but is not limited to, 6mm, 8mm or 10mm.

[0086] Furthermore, the needle tip of the second needle 2 is blunt (i.e., the needle tip is not sharpened). During use, the needle tip of the second needle 2 only serves to separate the cut hair follicle tissue and extract the hair follicle tissue, and will not cut the skin. Therefore, it can reduce damage to the hair follicle tissue structure.

[0087] In an optional embodiment of the present invention, such as Figures 4 to 8As shown, the firing device also includes a first connecting member 3 and a second connecting member 4. Both the first connecting member 3 and the second connecting member 4 are columnar. The first connecting member 3 has a third channel 301 that passes through it. One end of the first needle 1 is fixedly connected to the first connecting member 3, and the first channel of the first needle 1 communicates with the third channel 301 of the first connecting member 3. The other end of the first needle 1 is the needle tip. The second connecting member 4 has a fourth channel 401 that passes through it. One end of the second needle 2 is fixedly connected to the second connecting member 4, and the second channel of the second needle 2 and the storage cavity 501 communicate with the fourth channel 401 of the second connecting member 4. The other end of the second needle 2 is the needle tip. The needle tip of the second needle 2 can pass through the third channel 301 and the first channel in sequence and protrude from the needle tip of the first needle 1. By setting the first connecting member 3 and the second connecting member 4 to provide installation positions for the first needle 1 and the second needle 2 respectively, the first needle 1 and the second needle 2 are both detachable structural components, which facilitates the assembly and replacement of the first needle 1 and the second needle 2.

[0088] Furthermore, such as Figure 7 As shown, a sensing device 302 is provided on the end face of the first connector 3 near the needle tip of the first needle 1. When the sensing device 302 comes into contact with the patient's skin, the second needle 2 moves towards the patient's skin; when the sensing device 302 separates from the patient's skin, the second needle 2 stops rotating and then returns to its original position. The activation of the second needle 2 is controlled by the pressure on the sensing device 302 (i.e., the second needle 2 begins to rotate and move while the first needle 1 presses down to anchor and cut the skin). As the second needle 2 rotates and moves downward, it separates the hair follicle tissue from the surrounding skin. After the hair follicle is removed, the operator can lift the hair extraction device upward to separate the sensing device 302 from the patient's skin. At this time, the second needle 2 immediately stops rotating and retracts to its original position, thus preventing damage to other tissues of the patient, ensuring complete separation and extraction of the hair follicle, and reducing the occurrence of bleeding. Of course, the sensing device 302 can also be provided on the first needle 1, which can sense the contact between the hair extraction device and the patient's skin at a preset position and control the movement of the second needle 2 according to the sensing signal. In addition, during the process of the first needle 1 coming into contact with the patient's skin, the deformation of the first needle 1 can trigger the action of the second needle 2, thereby achieving automatic needle retrieval.

[0089] Specifically, such as Figure 13As shown, the triggering process of the sensing device 302 is as follows: the hair retrieval device confirms the execution of the hair retrieval action → locates the target hair follicle, the first needle 1 moves down to make the sensing device 302 contact the patient's skin → the sensing device 302 emits a sensing signal → the second needle 2 rotates and moves down 7mm at the same time to completely separate the hair follicle tissue from the surrounding skin → after the target hair follicle is retrieved, the first needle 1 moves up, the sensing device 302 separates from the patient's skin, the second needle 2 stops rotating and resets → whether the preset target number of hair follicle tissue has been retrieved → if the target number has not been reached, the above operation is repeated / if the target number has been reached, the hair retrieval ends.

[0090] The distance between the tip of the anchoring part 101 of the first needle 1 and the sensing device 302 can be set to, but is not limited to, 2 mm.

[0091] Furthermore, the sensing device 302 may be, but is not limited to, a flexible thin-film pressure sensor.

[0092] In an optional embodiment of the present invention, such as Figure 4 , Figure 9 , Figure 10 As shown, the storage component 5 has a first port 502, a second port 503, and a third port 504 that are respectively connected to the storage cavity 501. The first port 502 is an interface for connecting to the second connector 4. The second connector 4 and the first port 502 can be connected by threads, which not only facilitates disassembly and assembly but also ensures that the storage cavity 501 can be connected to the second channel through the first port 502 (i.e., the first port 502 is used to connect to the second channel). The second port 503 is a negative pressure interface, which is used to connect to the negative pressure device 6. By evacuating air through the negative pressure device 6, a negative pressure environment can be created in the storage cavity 501, thereby realizing the extraction of hair follicle tissue. The third port 504 is a saline injection port, which is used to connect to the saline supply device 7. The saline supply device 7 can continuously inject 4°C saline into the storage cavity 501, thereby ensuring that the storage cavity 501 is a sterile environment. Under low temperature and sterile environment, the survival rate of hair follicles can be improved, ensuring the smooth progress of hair transplantation surgery that takes a long time. Due to the suction effect of the negative pressure device 6 and the small diameter of the second channel in the second needle 2, the saline solution in the storage cavity 501 will not enter the second needle 2 during actual operation. Only a small amount of saline solution will be drawn out from the second port 503. However, since the saline solution supply device 7 continuously supplies saline solution to the storage cavity 501, it can ensure that there is always enough saline solution in the storage cavity 501 and maintain the low temperature environment in the storage cavity 501.

[0093] This invention allows for the use of different storage components 5 according to the needs of different patients. These different storage components 5 have different lengths, thus enabling the storage space of the storage cavity 501 to meet the storage requirements of different hair lengths. For example, a standard storage component 5 is suitable for most patients (hair length 1mm to 2mm), while a longer storage component 5 can extract short hair from patients who do not shave their heads (hair length 20mm to 30mm), and an extra-long storage component 5 can extract long hair from patients who do not shave their heads (hair length 80mm to 100mm), thus adapting to different hair transplant patients and expanding the applicability of the hair extraction device.

[0094] Furthermore, such as Figure 11 As shown, a filter device 505 is installed inside the storage cavity 501. The filter device 505 is located between the first opening 502 and the second opening 503. The filter device 505 reduces the amount of hair follicle tissue sucked out through the second opening 503, thereby preventing the hair follicle tissue from being trapped inside the storage cavity 501 and temporarily preserving the hair follicle tissue during the hair transplantation process. The first opening 502 of the storage component 5 and the second connecting component 4 can be connected by threads. After the number of hair follicle tissues stored in the storage cavity 501 reaches a preset maximum threshold, a new storage component 5 can be replaced to continue storing and collecting hair follicle tissues.

[0095] Furthermore, the filtration device 505 includes a filter cylinder and a filter screen. The filter cylinder is a cylindrical shape with openings at both ends. Multiple spiral grooves are provided on the inner wall of the filter cylinder. The filter screen is placed inside the filter cylinder, and the outer edge of the filter screen engages with the grooves.

[0096] Furthermore, the negative pressure device 6 can be, but is not limited to, a hospital's negative pressure suction system. The negative pressure device 6 is connected to the second port 503 on the storage component 5 via a negative pressure pipeline 10. A negative pressure regulating device 8 is installed on the negative pressure pipeline 10, and the power supply terminal of the negative pressure regulating device 8 is connected to a power source via a power adapter 9. The suction force of the negative pressure suction system can be set via the negative pressure regulating device 8, reducing damage to the separated hair follicle tissue caused by excessive suction force, ensuring the integrity of the extracted hair follicle tissue structure, and improving the survival rate of the hair follicles.

[0097] Specifically, such as Figure 12 As shown, the negative pressure regulating device 8 can be, but is not limited to, a flow regulating valve. The negative pressure regulating device 8 includes a pedal 801 and an adjustment button 802 mounted on the pedal 801. The opening of the flow regulating valve can be adjusted via the adjustment button 802. Pressing the adjustment button 802 controls the flow regulating valve to open, thereby providing suction force through the negative pressure device 6. In actual use, the negative pressure regulating device 8 can be placed under the operator's feet. The operator can control the extraction of hair follicle tissue in real time by stepping on the adjustment button 802, facilitating operation and effectively improving ease of use.

[0098] Specifically, such as Figure 14 As shown, the procedure for using the negative pressure regulating device 8 is as follows: Before the surgery begins, check whether each device is intact (i.e., whether each device can work normally) → connect the negative pressure tubing 10 to the negative pressure suction system and the storage device 5 respectively → adjust the appropriate negative pressure suction force → hair removal begins, after the second needle 2 separates the hair follicle tissue, step on the negative pressure regulating device 8 to control its suction force → after removing the hair follicle tissue, release the negative pressure regulating device 8 → determine whether the preset target number of hair follicle tissue has been reached → if the preset target number of hair follicle tissue has not been reached, repeat the operation of removing hair follicles / if the preset target number of hair follicle tissue has been reached, the surgery ends.

[0099] In an optional embodiment of the present invention, such as Figures 1 to 3 As shown, the hair-taking device also includes a rotary drive mechanism 200, which drives the second needle 2 to rotate along its own central axis. The rotary drive mechanism 200 includes a first motor 11 and a transmission assembly. The output shaft of the first motor 11 is connected to the second needle 2 through the transmission assembly, and the transmission assembly drives the second needle 2 to rotate along its own central axis.

[0100] Furthermore, such as Figures 1 to 3 As shown, the transmission assembly includes a splined shaft 19, with a negative pressure channel formed inside the splined shaft 19. The negative pressure channel connects the negative pressure device 6 and the storage cavity 501. In this embodiment, the output shaft of the first motor 11 is connected to the splined shaft 19 via the transmission assembly. One end of the splined shaft 19 is detachably connected to the storage component 5, and the other end of the splined shaft 19 is connected to the negative pressure pipeline interface 22. The second needle 2 is detachably connected to the storage component 5 via the second connector 4. The negative pressure channel of the splined shaft 19 is connected to one end of the negative pressure pipeline 10 via the negative pressure pipeline interface 22. The other end of the negative pressure pipeline 10 is connected to the negative pressure device 6. The negative pressure pipeline 10, the negative pressure channel, the storage cavity 501, and the second channel are sequentially connected. The first motor 11 can drive the splined shaft 19 to rotate via the transmission assembly, thereby driving the second connector 4 and the second needle 2 to rotate synchronously, achieving rotation control of the second needle 2.

[0101] Specifically, such as Figures 1 to 3 As shown, the transmission assembly includes a first gear 21 and a second gear 20. The first gear 21 is fixedly mounted on the output shaft of the first motor 11. A splined shaft 19 passes through the center of the second gear 20 and is fixedly connected to it. The teeth on the first gear 21 mesh with the teeth on the second gear 20. The first gear 21 is the driving gear, and the second gear 20 is the driven gear. The first motor 11 drives the first gear 21 to rotate, which in turn drives the second gear 20 to rotate, thus realizing the transmission of power.

[0102] In an optional embodiment of the present invention, such as Figures 1 to 3 As shown, the take-up and take-up device also includes a linear drive mechanism 100, which drives the second needle 2 to move axially along the first channel. The linear drive mechanism 100 includes a second motor 12, a lead screw 13, and a moving member 14. The moving member 14 is a long strip-shaped plate. The output shaft of the second motor 12 is connected to one end of the lead screw 13 via a coupling 18. The moving member 14 is movably mounted on the lead screw 13 along its axial direction. A spline shaft 19 is rotatably connected to the moving member 14 along its own central axis (e.g., a first bearing is provided between the spline shaft 19 and the moving member 14 to ensure that the spline shaft 19 can rotate circumferentially relative to the moving member 14, and also to limit the spline shaft 19 in the direction along its central axis). The second motor 12 drives the lead screw 13 to rotate, allowing the moving member 14 to move along the lead screw 13, thereby driving the spline shaft 19, the second connecting member 4, and the second needle 2 to move back and forth, thus controlling the back and forth position of the second needle 2. The movement distance of the second needle 2 can be controlled by setting the length of the lead screw 13. In one specific embodiment of the present invention, the maximum distance that the second needle 2 can move is 7mm.

[0103] Furthermore, such as Figures 1 to 3 As shown, the linear drive mechanism 100 also includes a mounting plate 15. A guide rail 1501 is provided on the surface of the mounting plate 15 along its length. The second motor 12 is mounted on the mounting plate 15 and located on the same side of the plate as the guide rail 1501. The extension direction of the lead screw 13 is parallel to the extension direction of the guide rail 1501. A moving member 14 is sleeved on the lead screw 13, and a slider 1401 is fixedly provided on the moving member 14. The slider 1401 is slidably connected to the guide rail 1501. Through the slidable connection between the guide rail 1501 and the moving member 14, the rotation of the moving member 14 is limited, thereby driving the second needle 2 to move via the second motor 12.

[0104] Specifically, such as Figures 1 to 3 As shown, the mounting plate 15 is also provided with a first mounting seat 16 and a second mounting seat 17. The two ends of the lead screw 13 are rotatably connected to the first mounting seat 16 and the second mounting seat 17 respectively through second bearings. The first mounting seat 16 and the second mounting seat 17 cooperate to support and position the lead screw 13, ensuring the stability of the lead screw 13 in the working state.

[0105] Furthermore, such as Figures 1 to 3As shown, the linear drive mechanism 100 also includes a support member 23, which is plate-shaped and can be moved along the axial direction of the lead screw 13 on the lead screw 13. The support member 23 is slidably connected to the guide rail 1501. The spline shaft 19 passes through the support member 23 and is rotatably connected to the support member 23 through a third bearing. The first motor 11 is mounted on the support member 23, thereby providing an installation position for the first motor 11 and supporting and positioning the rotary drive mechanism 200 to ensure the stability of the rotary drive mechanism 200.

[0106] In actual use, such as Figure 15 , Figure 16 As shown, a mechanical boom 2000 can be installed on the ceiling, and a take-up and take-up device 1000 can be set at the actuator end of the mechanical boom 2000. The mechanical boom 2000 drives the take-up and take-up device 1000 to move to the designated position, assisting the take-up and take-up device 1000 in completing precise take-up and take-up. The movement of the mechanical boom 2000 can be controlled by an operator.

[0107] The features and advantages of the firing device of the present invention are as follows:

[0108] 1. In this hair extraction device, the first needle 1 has an anchoring part 101 at the needle tip, which makes it easy for the anchoring part 101 to be inserted into the scalp tissue in the initial state of hair extraction, fix the hair extraction device, reduce the possibility of deviation, and increase the accuracy of hair extraction. Furthermore, the anchoring part 101 has cutting blades 1011 on both sides of its tip, which makes it easy to cut open the patient's skin, so that the second needle 2 can directly enter the subcutaneous tissue, further reducing the possibility of rotational deviation.

[0109] Second, in this hair extraction device, the rotation of the second needle 2 and the blunt needle tip can reduce damage to the hair follicle tissue. The activation of the second needle 2 is controlled by the pressure of the first needle 1. As the second needle 2 rotates and moves downward, it can separate the hair follicle tissue. After the hair follicle is removed, the hair extraction device is lifted to separate the first needle 1 from the skin. The second needle 2 then immediately stops rotating and retracts to its original position. The hair follicle is completely separated and removed without damaging other skin tissue, reducing intraoperative bleeding.

[0110] Third, this hair extraction device can create a negative pressure, sterile and temperature-stable environment in the storage cavity 501, which improves the survival rate of hair follicle tissue. In addition, the filter device 505 in the storage cavity 501 can prevent hair follicle tissue from leaking out, ensuring the smooth progress of hair transplant surgery that takes a long time.

[0111] Fourth, the hair extraction device can be adapted to different storage components 5 according to the needs of different patients, so that the hair extraction device of the present invention has a wider range of applications.

[0112] Fifth, in this hair extraction device, a negative pressure environment is created in the storage cavity 501 to extract hair follicle tissue. The negative pressure adjustment device 8 can set a suitable negative pressure suction force to reduce damage to the separated hair follicle tissue, ensure the integrity of the extracted hair follicle tissue, and increase the survival rate of hair follicles after hair transplantation surgery.

[0113] VI. Throughout the process of breaking, separating, and extracting hair follicle tissue, and storing the hair follicle tissue, this hair extraction device can reduce damage to the hair follicle tissue, speed up the surgical process, reduce unnecessary surgical steps, improve surgical time and efficiency, thereby strengthening the preservation of the hair follicle tissue, ensuring the integrity rate of hair follicles from the root operation, and improving the survival rate of hair follicle tissue transplantation in the later stage.

[0114] Implementation Method 2

[0115] This invention provides a hair transplant robot, which includes the aforementioned hair extraction device 1000 and a robot body. The hair extraction device 1000 is disposed at the execution end of the robot body. The robot body can drive the hair extraction device 1000 to a designated position to complete the hair extraction operation.

[0116] In another optional embodiment of the invention, such as Figure 17 , Figure 18 As shown, the robot body includes a robot arm 3000, and a hair-retrieving device 1000 is disposed at the execution end of the robot arm 3000. Through the image display device and control algorithm on the hair transplant robot, the execution end can be accurately moved to the designated position, realizing automatic hair retrieval by the robot.

[0117] Both the mechanical boom 2000 and the robotic arm 3000 are multi-degree-of-freedom robotic arms.

[0118] like Figure 19 As shown, the working process of the hair transplant robot of the present invention is as follows: Before the hair transplant, pre-planning is performed (including the location of the hairline, the extraction area, the transplant area, the hair density in the transplant area, and the direction of hair growth, etc.). After the patient is positioned, the extraction device 1000 is disinfected, and the disinfected first needle 1, second needle 2, and storage component 5 are assembled to complete the preparation for extraction. Anesthesia and scalp swelling are performed on the area where the patient will undergo surgery. After the extraction position is determined, the extraction device 1000 is controlled to extract hair until the target number of hairs is obtained. During the extraction process, the storage component 5 is replaced when the preset number of hair follicles is reached. The assistant pre-processes the hair follicles in the replaced storage component 5, and the extracted hair follicles can be stored in low-temperature saline (e.g., ice-cold saline) for transplantation. After the preset number of hair follicles is reached, holes are drilled and implanted in the patient's preset transplant area according to the pre-operative plan. After all hair transplant operations are completed, the entire hair transplant process ends.

[0119] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
