[0067] The present disclosure will be described below with reference to the accompanying drawings, wherein the accompanying drawings illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in a variety of different ways and is not limited to the embodiments described below; it should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0068] The technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application.

[0069] like Figure 1 As shown, this embodiment provides a hair follicle manipulation device, which includes a main needle 10 and an auxiliary needle assembly. The needle head of the main needle 10 has a lumen 112 for extracting or implanting hair follicles, and the auxiliary needle assembly is arranged next to the main needle 10, and the auxiliary needle assembly has the same orientation as the main needle 10, ensuring that the main needle 10 and the auxiliary needle assembly can be inserted into the same target area.

[0070] In this embodiment, the main needle 10 and the auxiliary needle assembly can be controlled to move forward or backward along the direction pointed by the needle tip to insert into the same target area. The auxiliary needle assembly in this embodiment is used to pierce the surface of the target to form a pre-opening 81, and then the main needle 10 is controlled to be inserted from the vicinity of the pre-opening 81, or directly from the pre-opening 81. Accordingly, the main needle 10 can be inserted into the interior of the target through the assistance of the pre-opening 81.

[0071] In this embodiment, the main needle 10 serves as the main structure for extracting or implanting hair follicles. It is inserted into the scalp through the pre-formed pre-opening 81 of the auxiliary needle assembly, which can more conveniently extract and implant hair follicles. The auxiliary needle assembly pre-stretches the scalp, which effectively avoids the rotation of the scalp when the extraction needle is inserted or removed, causing the hair follicles to be squeezed and displaced, affecting the accuracy of hair follicle extraction or implantation, and also avoids the hair follicles from being damaged during the drilling process, thereby helping to improve the efficiency of hair follicle extraction and implantation.

[0072] Specifically, the main needle 10 and the auxiliary needle assembly can be arranged parallel to each other, and the auxiliary needle assembly is close to the main needle 10, ensuring that the main needle 10 can be inserted into or close to the pre-opening 81 formed by the auxiliary needle assembly. Of course, the auxiliary needle assembly can also form an acute angle with the main needle 10, so that the main needle 10 can be more easily directly inserted into the pre-opening 81.

[0073] It is worth mentioning that in this embodiment, the thickness of the needle tip of the auxiliary needle assembly is less than the thickness of the needle tip of the main needle 10. In other words, the needle tip of the auxiliary needle assembly is sharper than the needle tip of the main needle 10, and the needle end face of the auxiliary needle assembly is sharp, which is convenient for quickly breaking the skin, and at the same time can prevent the main needle 10 from being too sharp and damaging the hair follicles to a certain extent.

[0074] like Figure 2 As shown, in one embodiment, the auxiliary needle assembly is an auxiliary needle, namely the first auxiliary needle 21, and the first auxiliary needle 21 can move forward in an alternating manner with the main needle 10, that is, when the first auxiliary needle 21 moves forward, the main needle 10 moves backward, and when the main needle 10 moves forward, the first auxiliary needle 21 moves backward. In this way, the first auxiliary needle 21 not only plays the role of opening the pre-opening 81, but also can cooperate with the movement of the active needle 10 when extracting and planting hair follicles. The alternating movement of the first auxiliary needle 21 and the main needle 10 can reduce the displacement of the scalp 80 and ensure that the hair follicles are relatively stable, so as to facilitate the operation of extracting and planting hair follicles.

[0075] Specifically, the first auxiliary needle 21 and the main needle 10 move alternately, and the first auxiliary needle 21 and the main needle 10 can respectively apply forces in opposite directions to the scalp 80. In this way, the two forces in opposite directions cancel each other out, reducing the force on the scalp 80 in a single direction. Therefore, such an operation is conducive to keeping the scalp 80 stable during the operation, facilitating the main needle 10 to extract or plant hair follicles, and ensuring the accuracy of the operation position to avoid excessive squeezing of the hair follicles and causing damage.

[0076] The auxiliary needle provided in this embodiment has a finer tip than the main needle 10, so it is more capable of creating a pre-opening 81 without causing skin displacement. The main needle 10 cuts in with the help of the pre-opening 81, and the obstacles it encounters are significantly reduced, making it easier to cut in. This embodiment extracts or implants hair follicles by staggered advancement of the first auxiliary needle 21 and the main needle 10, replacing the traditional method of rotating the extraction needle, which can reduce the size of the wound opened on the scalp 80 when the extraction needle rotates at high speed to drill the hair follicles, and effectively prevent the scalp 80 from loosening and squeezing the hair follicles during the high-speed rotation of the extraction needle, thereby improving the efficiency of hair follicle extraction and implantation and reducing the chance of damage to the hair follicles.

[0077] In other embodiments, the auxiliary needle assembly may also include two auxiliary needles.

[0078] like Figure 1 As shown, the auxiliary needle assembly includes a first auxiliary needle 21 and a second auxiliary needle 22, which are arranged around the main needle 10. Preferably, the first auxiliary needle 21 and the second auxiliary needle 22 are parallel to the main needle 10, and both can be located on the same side of the main needle 10 or on opposite sides of the main needle 10.

[0079] The second auxiliary needle 22 can have the same moving mode as the first auxiliary needle 21, that is, the second auxiliary needle 22 can also move forward alternately with the main needle 10, so the second auxiliary needle 22 also has the effect of the first auxiliary needle 21, which will not be repeated here.

[0080] It is worth mentioning that the second auxiliary needle 22 can move synchronously with the first auxiliary needle 21, or can move alternately with the first auxiliary needle 21, that is, the second auxiliary needle 22 can move forward in batches with the first auxiliary needle 21 and the main needle 10 respectively.

[0081] In this embodiment, the first auxiliary needle 21 and the second auxiliary needle 22 are arranged to move forward alternately with the main needle 10. Compared with the interlaced movement of a single auxiliary needle and the main needle 10, it can avoid the damage to the scalp tissue by too frequent interlaced movement of a single auxiliary needle, thereby protecting the scalp tissue to a certain extent.

[0082] like Figure 1 As shown, in this embodiment, the main needle 10 includes a needle tube and a needle tip 110 arranged on the needle tube. The needle tip 110 has an inclined section so that the lumen 112 is exposed as an inclined incision 111 on the section. In this way, the sharpness of the needle tip of the main needle 10 can be improved, making it easier to insert into the scalp 80.

[0083] like Figure 1As shown, in one embodiment, the first auxiliary needle 21 and the second auxiliary needle 22 are respectively arranged on opposite sides of the main needle 10. The first auxiliary needle 21 and the second auxiliary needle 22 are respectively movable on both sides of the main needle 10, which can better balance the scalp tissue on both sides of the pre-opening 81, reduce scalp shaking, reduce the compression of the needle on the scalp, and further protect the hair follicles.

[0084] In this embodiment, from a macroscopic point of view, the pre-opening 81 is a smaller opening, and the needle tips of the main needle 10, the first auxiliary needle 21, and the second auxiliary needle 22 are regarded as the same point, and they can be regarded as being inserted into the pre-opening 81. However, from a microscopic point of view, the needle tips of the main needle 10, the first auxiliary needle 21, and the second auxiliary needle 22 are three different points.

[0085] Here, if Figure 1 As shown, the plane perpendicular to the direction of the main needle 10 is taken as the first plane AA. On the first plane AA, the incision direction B of the main needle 10 is perpendicular to the line connecting the first auxiliary needle 21 and the second auxiliary needle 22. In this way, the insertion area of ​​the needle tip 110 of the main needle 10 can be located between the first auxiliary needle 21 and the second auxiliary needle 22. The first auxiliary needle 21 and the second auxiliary needle 22 are at the same distance from the hair follicles, presenting a symmetrical posture. The two pre-openings 81 cut by the first auxiliary needle 21 and the second auxiliary needle 22 are equivalent to the openings cut by the main needle 10, thereby forming a larger opening. In this way, with the assistance of the two pre-openings 81, the main needle 10 is easier to cut in, and compared with the high-speed rotating main needle 10, it causes less damage to the scalp tissue. Moreover, the cooperation of the first auxiliary needle 21 and the second auxiliary needle 22 is also conducive to the force balance of the scalp tissue on both sides of the hair follicles, reducing the extrusion of the hair follicles and ensuring the safety of the hair follicles.

[0086] like Figure 2 As shown, when there is only the first auxiliary needle 21, the needle incision of the first auxiliary needle 21 and the incision direction B of the main needle 10 can be set in the opposite direction. In this way, it is ensured that the tip part of the main needle 10 can be inserted into the skin at the position closest to the pre-opening 81 formed by inserting the first auxiliary needle 21, which can also improve the ease with which the main needle 10 cuts into the skin.

[0087] In another embodiment, the auxiliary needle assembly may be provided with three auxiliary needles, and the auxiliary needle assembly includes a first auxiliary needle 21 , a second auxiliary needle 22 and a third auxiliary needle 23 .

[0088] like Figure 3 As shown, on the first plane AA, the line connecting the third auxiliary needle 23 and the main needle 10 is perpendicular to the line connecting the first auxiliary needle 21 and the second auxiliary needle 22, and the third auxiliary needle 23 is located on the symmetry axis of the first auxiliary needle 21 and the second auxiliary needle 22. At the same time, the third auxiliary needle 23 can also move forward alternately with the main needle 10, so the third auxiliary needle 23 also has the same effect as the first auxiliary needle 21 and the second auxiliary needle 22, which will not be repeated here.

[0089] In addition, the third auxiliary needle 23 can move synchronously with the first auxiliary needle 21 and the second auxiliary needle 22, or can move alternately with the first auxiliary needle 21 and the second auxiliary needle 22. That is, the first auxiliary needle 21, the second auxiliary needle 22 and the third auxiliary needle 23 move forward in batches in an alternating manner with the main needle 10.

[0090] like Figure 3 As shown, the opening direction B of the main needle 10 can be opposite to the direction of the third auxiliary needle 23. In this way, the tip of the main needle 10 can be inserted into the skin at a position closest to the pre-opening 81 formed by inserting the first auxiliary needle 21, the second auxiliary needle 22 and the third auxiliary needle 23, further improving the ease of the main needle 10 to cut into the skin.

[0091] like Figure 4 As shown, further, in one embodiment, the auxiliary needle assembly is provided with four auxiliary needles, namely, it also includes a fourth auxiliary needle 24, and the line connecting the fourth auxiliary needle 24 and the third auxiliary needle 23 is perpendicular to the line connecting the first auxiliary needle 21 and the second auxiliary needle 22. Similarly, based on the movement mode and effect of the third auxiliary needle 23, the fourth auxiliary needle 24 also has all the above advantages, and the pre-opening 81 is symmetrically and evenly located around the hair follicle, which helps to balance the force on the tissue around the hair follicle and better protect the hair follicle from being squeezed.

[0092] Based on the same design concept, the number of auxiliary needles of the auxiliary needle assembly may also be greater than 4. Therefore, the specific number of auxiliary needles of the auxiliary needle assembly in this embodiment is not limited exclusively.

[0093] like Figure 5 As shown, in one embodiment, a plane perpendicular to the direction of the main needle 10 is taken as the first plane AA, on which the line between the first auxiliary needle 21 and the main needle 10 is the first line L1, and the line between the second auxiliary needle 22 and the main needle 10 is the second line L2, and the angle between the first line L1 and the second line L2 is less than 180 degrees, so that the first auxiliary needle 21 and the second auxiliary needle 22 are both located on the same side of the main needle 10; and the incision direction B of the main needle 10 is away from the side where the first auxiliary needle 21 and the second auxiliary needle 22 are located.

[0094] In this way, the needle tip 110 of the main needle 10 is relatively close to the first auxiliary needle 21 and the second auxiliary needle 22, that is, the needle tip 110 of the main needle 10 can be more easily and accurately inserted into the skin with the assistance of the pre-opening 81 formed by the first auxiliary needle 21 and the second auxiliary needle 22, thereby facilitating the extraction and implantation of hair follicles.

[0095] like Figure 5As shown, when the auxiliary needle assembly includes the first auxiliary needle 21, the second auxiliary needle 22 and the third auxiliary needle 23, on the first plane AA, the line between the third auxiliary needle 23 and the main needle 10 is the third line L3, and the third line L3 is located between the fan-shaped formed by the first line L1 and the second line L2. And the incision of the main needle 10 faces B away from the side where the third auxiliary needle 23 is located. In this way, the opening of the lower needle of the main needle 10 is closer to the pre-opening 81 formed by the first auxiliary needle 21, the second auxiliary needle 22 and the third auxiliary needle 23, and it is easier to form a large opening with the above-mentioned pre-openings 81, which is convenient for the main needle 10 to extract or plant hair follicles.

[0096] Preferably, the angle between the first connecting line L1 and the second connecting line L2 is between 75 and 120 degrees. In this way, the three pre-openings formed by the first auxiliary needle 21, the third auxiliary needle 23, and the second auxiliary needle 22 in this fan-shaped area are equivalent to being cut in sections along the circumference of the circular opening of the main needle 10. Under this premise, when the main needle 10 is inserted, it is as smooth as a hot knife cutting butter.

[0097] In the aforementioned embodiments, the auxiliary needle may be a common needle-like structure with a smooth outer surface. Figure 1 As shown, in some other embodiments, the auxiliary needle of the auxiliary needle assembly has an auxiliary protrusion structure.

[0098] Taking the first auxiliary needle 21 as an example, the first auxiliary needle 21 includes a main structure 211 and an auxiliary protrusion 212. The surface of the main structure 211 facing the main needle 10 matches the shape of the main needle 10, and there may be a very small gap between them. The auxiliary protrusion 212 is arranged on the surface of the main structure 211 facing away from the main needle 10, and is used to assist the first auxiliary needle 21 to pierce the target.

[0099] In this embodiment, the auxiliary protrusion 212 can play a role in stretching the scalp 80 after the first auxiliary needle 21 is inserted into the scalp 80. First, it can increase the contact area with the scalp 80 and expand the pre-opening 81 made by the first auxiliary needle 21 on the scalp 80, so that the main needle 10 can be inserted more smoothly. Secondly, since the specifications of the main needle 10 are larger, the disturbance to the scalp is also greater. The specifications of the auxiliary needle are increased by the auxiliary protrusion 212, so that when the two move in reverse, the auxiliary needle can more easily offset the disturbance of the scalp by the main needle 10 and reduce the squeezing of the hair follicles; finally, the auxiliary protrusion 212 can also play an additional role in tightening the scalp, making the scalp tighter and facilitating the hair follicle extraction or planting operation.

[0100] Specifically, Figure 1 As shown, the auxiliary protrusion 212 includes a tip auxiliary portion 2121 and a middle auxiliary portion 2122 .

[0101] The tip auxiliary portion 2121 is disposed at the tip of the main structure 211 , and the thickness of the tip auxiliary portion 2121 gradually increases from the tip direction of the main structure 211 toward the tail end direction of the main structure 211 , so as to facilitate the auxiliary needle tip to be inserted into the scalp 80 .

[0102] The middle auxiliary portion 2122 is spaced apart from the tip auxiliary portion 2121 to form a receiving groove 213 between the tip auxiliary portion 2121 and the middle auxiliary portion 2122. The middle auxiliary portion 2122 has a slope 2123 on one side facing the tip auxiliary portion 2121. The thickness of the slope 2123 also gradually increases from the tip direction of the main structure 211 toward the tail direction of the main structure 211, so as to facilitate the middle part of the auxiliary needle to be inserted into the scalp 80 and squeeze and stretch the scalp 80, thereby further enhancing the above-mentioned effect.

[0103] Furthermore, there are a plurality of intermediate auxiliary parts 2122, and these intermediate auxiliary parts 2122 are arranged at intervals along the length direction of the first auxiliary needle 21, so that a receiving groove 213 is also formed between each intermediate auxiliary part 2122. The receiving groove 213 increases the contact area between the auxiliary needle and the scalp 80, so that when the main needle 10 and the auxiliary assembly move in the reverse direction, the auxiliary needle can more easily offset the disturbance of the main needle 10 on the scalp, thereby reducing the squeezing of the hair follicles.

[0104] This embodiment is also equipped with a driving mechanism 40, which is respectively connected to the main needle 10 and the auxiliary needle assembly, and is used to drive the main needle 10 and the auxiliary needle assembly to move forward or backward along the direction pointed by the needle tip.

[0105] like Figure 6 As shown, this embodiment has a first supporting flange 31 and a second supporting flange 32, and the first supporting flange 31 and the second supporting flange 32 are connected by a connecting column 33 to form a frame. A linear track 50 is installed on the first supporting flange 31, and the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22 respectively have sliding parts that cooperate with the linear track 50, so that the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22 can slide on the linear track 50.

[0106] A driving mechanism 40 is arranged on the second supporting flange 32, and the output end of the driving mechanism 40 is connected to the needle tail 120 of the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22. The driving mechanism 40 can push the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22 to slide along the linear track 50 respectively to realize the needle lowering and needle retracting movements of the needle tube.

[0107] Specifically, Figure 6As shown, springs 60 are provided between the needle tails 120 of the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22 and the linear track 50, respectively, to ensure that the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22 can automatically return to their positions when the driving mechanism 40 is retracted. Of course, the insertion and extraction steps of the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22 can be driven by the driving mechanism 40, and the spring 60 can serve as an auxiliary structure.

[0108] In this embodiment, the driving mechanism 40 can drive the movement of the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22 respectively through the transmission mechanism, and can also realize the power output switching of the main needle 10, the first auxiliary needle 21 and the second auxiliary needle 22.

[0109] As a further improvement, in this embodiment, the main needle 10 can be rotated during the insertion, extraction and implantation operations as in the prior art, so as to improve the efficiency of the insertion of the main needle 10. However, it is worth mentioning that in the prior art, in order to ensure that the skin will not be twisted and tangled during drilling, the rotation speed of the main needle 10 is very high, which can reach hundreds or even thousands of revolutions per minute. In this embodiment, on the contrary, the rotation of the main needle 10 should be as slow as possible, such as dozens of revolutions per minute, or even a single-digit speed. This is because, in this patent, by providing an auxiliary needle and its pre-opening, the main needle 10 can easily cut into the skin. At this time, the use of a slower rotation speed can make the main needle cut the skin very evenly without causing a sharp expansion of the wound.

[0110] On this basis, the hair follicle manipulation device may be provided with a rotating mechanism 70, which is movably connected to the main needle 10 so that the main needle 10 rotates along its axial direction during the process of advancing or retreating.

[0111] Specifically, Figure 7 As shown, the rotating mechanism 70 includes a spiral track 71 and a guide block 72 limited in the spiral track 71. The spiral track 71 is fixed to the bracket or the above-mentioned support flange. The spiral track 71 remains fixed, and the guide block 72 is connected to the main needle 10 and moves with the main needle 10. When the main needle 10 moves forward or backward, the guide block 72 is limited by the spiral track 71 and slides along the spiral track 71, thereby rotating the main needle 10.

[0112] like Figure 8 As shown, this embodiment also provides a control method of a hair follicle manipulation device for non-disease diagnosis and treatment purposes, comprising the following steps:

[0113] Step 1: insert the auxiliary needle assembly into the scalp 80 to obtain a pre-opening 81, and the auxiliary needle assembly generates a first force on the scalp 80;

[0114] Step 2: insert the main needle 10 into the target through the pre-opening 81, the main needle 10 generates a second force on the scalp 80, and controls the auxiliary needle assembly to retreat when the main needle 10 moves forward;

[0115] Move the auxiliary needle assembly and the main needle 10 forward alternately;

[0116] When the main needle 10 moves forward, the auxiliary needle assembly is controlled to move backward; when the main needle 10 moves backward, the auxiliary needle assembly is controlled to move forward, and the first force is in opposite directions to the second force, so that the first force and the second force can offset each other.

[0117] It is worth mentioning that the method of this patent can be applied to the implantation and extraction of hair follicles in the human body, so it can be used for the diagnosis and treatment of diseases. However, the above control method of this patent can also be used for non-living objects, such as hair implantation operations of dolls, so it can be regarded as being able to be used for non-disease diagnosis and treatment purposes.

[0118] In this way, the main needle 10 cuts in with the help of the pre-opening 81, and the obstacles it encounters are significantly reduced, making it easier to cut in. This embodiment extracts or implants hair follicles by staggered advancement of the auxiliary component and the main needle 10, replacing the traditional method of rotating the extraction needle to insert the needle, which can reduce the size of the wound on the scalp 80 when the extraction needle rotates at high speed to drill the hair follicles, and effectively prevent the scalp 80 from loosening and squeezing the hair follicles during the high-speed rotation of the extraction needle, thereby improving the efficiency of hair follicle extraction and implantation and reducing the probability of damage to the hair follicles.

[0119] Specifically, Fig. 9 As shown, in this embodiment, a first auxiliary needle 21 and a second auxiliary needle 22 are provided; the specific method is as follows:

[0120] S1: First, insert the first auxiliary needle 21 and the main needle 10 into the scalp 80.

[0121] S2: The first auxiliary needle 21 is further inserted into the scalp 80 to obtain a pre-opening 81. During the advancement of the first auxiliary needle 21, the main needle 10 is moved backward, and the second force exerted by the main needle 10 on the scalp 80 and the first force exerted by the first auxiliary needle 21 on the scalp 80 offset each other.

[0122] S3: After a certain displacement in S2, the main needle 10 is inserted into the pre-opening 81, and the first auxiliary needle 21 moves backward when the main needle 10 moves forward, and the first force and the second force cancel each other out.

[0123] S4: After a certain displacement in S3, the second auxiliary needle 22 is inserted into the scalp 80 to obtain a pre-opening 81, and the main needle 10 retreats when the second auxiliary needle 22 advances, and the second force exerted by the main needle 10 on the scalp 80 and the first force exerted by the second auxiliary needle 22 on the scalp 80 offset each other.

[0124] S5: After a certain displacement in S4, the main needle 10 is moved forward one more step to be inserted into the pre-opening 81, and the second auxiliary needle 22 moves backward when the main needle 10 moves forward, and the first force and the second force cancel each other out.

[0125] S6: After S5 moves for a certain distance, step S6 repeats step S2, and the first auxiliary needle 21 and the second auxiliary needle 22 move forward alternately with the main needle 10, and the operation is cyclic.

[0126] The above steps are steps for inserting the main needle 10 , and the steps for removing the main needle 10 are the same, and the steps can be performed in reverse, which will not be repeated here.

[0127] Likewise, the auxiliary components are not limited to two, but may include three or four or even more. Multiple auxiliary components move alternately with the main needle 10 in batches, and also have the above advantages.

[0128] The present embodiment can effectively realize the extraction and implantation of hair follicles through the reasonable coordination of the above-mentioned needle insertion step and needle removal step. The auxiliary needle assembly and the main needle 10 move alternately, so that the forces acting on the scalp offset each other, reducing the disturbance of the scalp 80 by the main needle 10 during the operation, which is beneficial to the stability of the scalp during the operation, facilitating the insertion of the main needle 10 to extract or implant hair follicles, ensuring the accuracy of the operation position, and also avoiding the disturbance of the scalp 80 causing excessive squeezing and damage of the hair follicles, thereby effectively improving the success rate of the hair follicle implantation operation.

[0129] This embodiment also provides a non-transitory computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the steps described above are implemented. Therefore, the non-transitory computer-readable storage medium also has all the advantages of the above embodiments, which will not be repeated here.

[0130] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
