Detailed Implementation

[0049] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0050] Unless otherwise defined, all technical and scientific terms used in the present application have the same meanings as those commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application; the terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above description of drawings are intended to cover the non-exclusive inclusion.

[0051] The terms "first", "second", etc. in the specification and claims of the present application or in the above description of drawings are used to distinguish different objects, rather than to describe a specific order or primary and secondary relationship.

[0052] In the present application, the phrase "embodiments" means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase at various places in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments.

[0053] Referring to Figures 1 to 5 In a first aspect, the embodiments of the present application provide a scalp tensioning device 10, which specifically comprises a support module 11, a fixing module 12 and a tension adjustment module 13. The fixing module 12 is arranged on the support module 11 to be connected to the scalp. The tension adjustment module 13 is used to apply an action force of the support module 11 towards the scalp to fasten the fixing module 12 on the scalp and drive the support module 11 to move on the scalp to switch the support module 11 from a first position to a second position on the scalp.

[0054] The scalp tensioning device 10 provided by the embodiment of the present application can play two roles through the tightness adjusting module 13 acting on the support module 11. First, when the support module 11 is connected to the scalp, the tightness adjusting module 13 is used to apply an action force of the support module 11 to the scalp to fix the support module 11 and the scalp. Second, when the support module 11 is closely attached to the scalp, the tightness adjusting module 13 is also used to drive the support module 11 to move on the scalp to realize the tensioning of the scalp. The tightness adjusting module 13 provided by the present application can simultaneously drive the support module 11 to press the scalp and move on the scalp, and by providing sufficient pressure of the support module 11, it is ensured that the support module 11 is always closely attached to the scalp during the movement of the support module 11 on the scalp, and will not fall off from the scalp. By setting the tightness adjusting module 13, the present application can effectively tension the scalp during the hair follicle extraction and improve the comfort experience of the patient during the operation, and has simple structure and low cost, and wide application range.

[0055] In some embodiments, the support module 11 is a carrier acting on the scalp, and in order to ensure the fit of the support module 11 and the contour of the scalp, the support module 11 can be preferably made of a material with micro elasticity. In this way, during the process of the tightness adjusting module 13 applying the action force of the support module 11 to the scalp and driving the support module 11 to move on the scalp, the support module 11 will not produce hard pulling and interference with the scalp, and the slight deformation of the support module 11 during the movement can ensure the close attachment of the support module 11 and the scalp, which can improve the tensioning effect of the scalp and improve the use experience of the patient. As a preferred, the support module 11 can be made of a plastic material with micro elasticity, which can integrate support and deformation. Of course, the support module 11 of the present embodiment can also be made of other materials, which is not limited here, and the specific material can be selected flexibly according to the actual situation of the patient, which is within the protection scope of the present patent, and will not be described in detail here.

[0056] Of course, in the present embodiment, the structure of the support module 11 can also be selected flexibly according to the actual situation of the patient, for example, it can be selected to have a long strip-shaped plate structure, and during the process of the tightness adjusting module 13 pulling the support module 11 to move on the scalp, since the moving direction of the support module 11 is perpendicular to the length direction of the support module 11, the area of the scalp tensioning area can be effectively expanded, so as to reduce the number of times of tensioning the scalp, and further improve the efficiency of the hair follicle extraction.

[0057] In some embodiments, the tension adjustment module 13 can comprise a tensioning member, one end of the tensioning member is connected to the support module 11, and the other end of the tensioning member is connected to other devices, and the tensioning member is used to apply a force to the support module 11 towards the scalp and to apply a force to drive the support module 11 to move on the scalp.

[0058] As preferred, referring to Figures 1 to 3 , the tensioning member can comprise a buckle rope 131, one end of the buckle rope 131 is fixedly connected to the support module 11, and the other end of the buckle rope 131 is connected to other devices, such as a seat for carrying the patient, to achieve the tension of the scalp. In order to facilitate a detailed description of the present embodiment, the following will be described in detail with the seat as an example, but not limited thereto.

[0059] In one application scenario, the patient lies on the seat with his face downward, and the medical staff first places the scalp tension device 10 at the edge of the designated hair follicle extraction area of the patient, and then fixes the support module 11 to the scalp position through the fixing module 12. Then, the medical staff applies a downward oblique force to the buckle rope 131 connected to the support module 11, which is decomposed into a vertical downward vertical force and a horizontal lateral force, the vertical force is the force applied by the buckle rope 131 to the support module 11 towards the scalp, to tighten the fixing module 12 and the support module 11 on the scalp. Correspondingly, the lateral force is the force used to drive the support module 11 to move on the scalp, to switch the support module 11 from the first position on the scalp to the second position, and finally to achieve the tension of the scalp. After the scalp is in the tension state, the medical staff fixes the buckle rope 131 to the seat, so that the hair follicle extraction area is always in the tension state, facilitating the medical staff to perform the hair follicle transplantation surgery.

[0060] Further, in the present embodiment, the buckle rope 131 is preferably made of a nylon rope or a metal rope without elasticity, so that the vertical force and the lateral force cannot be decomposed by the elastic part, effectively avoiding the weakening of the force, thereby effectively improving the tension effect of the scalp. Of course, the buckle rope 131 with a slight elasticity is also within the protection scope of the present patent, which is not limited herein.

[0061] Further, in the present embodiment, referring to Figure 1 , the support module 11 has an acting surface 112 for abutting the fixing module 12, and the acting surface 112 can be directly formed on one end surface of the support module 11. Since the scalp is not a complete plane, it has a certain curvature, especially when the area of the hair follicle extraction area is larger, the curvature is larger. Therefore, in order to make the support module 11 and the scalp have better fit, the acting surface 112 can be preferably arc-shaped concave, and the profile of the arc-shaped concave surface is adapted to the scalp.

[0062] Further, in this embodiment, continuing to refer to Figure 1 , the fixing module 12 is arranged on the supporting module 11 to abut the scalp. As preferred, the fixing module 12 can include at least one of a needle, a barb, and a micro-barb arranged on the action surface 112 and used to abut the scalp. Preferably, the needle or the barb or the micro-barb can be preferably made of metal material, which can be directly fixed on the action surface 112 of the supporting module 11 in the process of casting the supporting module 11, and the integrated structure can greatly improve the stability of the structure of the fixing module 12, but is not limited thereto.

[0063] Hereinafter, the embodiment is fully described by taking the barb as an example, but is not limited thereto. As preferred, the free end of the barb can be obliquely arranged toward the side of the supporting module 11 where the rope 131 is arranged, that is, obliquely arranged toward the side of the moving direction of the supporting module 11. In this way, when the barb hooks the scalp, since the oblique direction of the barb is consistent with the force direction of the rope 131, when the supporting module 11 is subjected to the pulling force of the rope 131, the barb can tightly hold the scalp, so that the part of the scalp hooked by the barb can move on the scalp together with the supporting module 11 until the supporting module 11 in the first position is pulled to the second position by the rope 131, thereby realizing the tensioning of the hair follicle extraction area.

[0064] As a preferred example of this embodiment, referring to Figure 2 and Figure 3 , the side of the supporting module 11 opposite to the fixing module 12 is provided with at least one clamping portion 111, one end of the rope 131 is buckled to the clamping portion 111, and the other end is connected and fixed to other devices, for example, connected and fixed to a seat for carrying the hair follicle transplantation patient, so as to maintain the supporting module 11 in the second position on the scalp, so that the scalp is tightly stretched under the action of the supporting module 11. Of course, if the seat is used to abut the position of the rope 131 which is far away from the patient's scalp, the rope 131 and the seat can also be connected by adding rope components such as pulling ropes, buckling belts, and lacing belts, so as to realize the fixation of the rope 131 and the seat, which are within the protection scope of the patent, and will not be described in detail here.

[0065] Specifically, continuing to refer to Figure 2 and Figure 3In order to facilitate the quick assembly and disassembly of the buckling rope 131 and the clamping part 111, the clamping part 111 can comprise a first clamping groove 1111, which is preferably arranged at the edge of the support module 11 opposite to the fixed module 12, and is preferably integrally formed with the support module 11. The integral structure not only improves the stability of the first clamping groove 1111, but also has the same slight elasticity as the support module 11, which facilitates the installation and disassembly of the buckling rope 131, but is not limited thereto.

[0066] Specifically, the number of the first clamping groove 1111 can be two, and the two first clamping grooves 1111 are arranged on the opposite sides of the edge of the support module 11 along the length direction. The first clamping groove 1111 is internally provided with a receiving part, and the upper end face of the receiving part is provided with an opening for guiding the receiving part. The buckling rope 131 can be preferably in the form of a ring-shaped rope, the contour of the receiving part is matched with the cross section of the buckling rope 131, and the width of the opening is smaller than the diameter of the buckling rope 131. In this way, when the buckling rope 131 is clamped into the receiving part from the opening, the buckling rope 131 will not be separated from the first clamping groove 1111 when the tensioning force of the buckling rope 131 is applied to the scalp.

[0067] In the embodiment, the number of the buckling rope 131 can be two, and the two buckling ropes 131 are sequentially clamped into the two first clamping grooves 1111. Of course, the number of the buckling rope 131 can also be one, and one buckling rope 131 is clamped into the two first clamping grooves 1111 at the same time to fix the buckling rope 131 and the support module 11. It is also within the protection scope of the present patent. That is to say, the present patent does not specifically limit the specific number of the first clamping groove 1111 and the buckling rope 131, but only needs to ensure that the buckling rope 131 can drive the support module 11 to move on the scalp after being connected to the support module 11, so that the support module 11 is always in a state of being closely bonded to the scalp during the movement of the support module 11 from the first position on the scalp to the second position, and will not fall off the scalp.

[0068] It is worth mentioning that, in the embodiment, the clamping mode of the buckling rope 131 and the first clamping groove 1111 can facilitate the disassembly and replacement of the buckling rope 131 or the support module 11, and improve the convenience of the scalp tensioning device 10 in actual use.

[0069] Of course, in the present embodiment, the support module 11 and the tension adjustment module 13 can also be of an integrated structure. For example, when the tension adjustment module 13 comprises a loop-shaped tightening rope 131, it can be preferred that the support module 11 is formed by extending outwardly in a partial area of the tightening rope 131. That is to say, the support module 11 and the tightening rope 131 are integrally formed by casting. Such a structure can make the stability of both stronger, effectively ensuring that the tightening rope 131 can provide sufficient force to move the support module 11 on the scalp. Of course, the tension adjustment module 13 of the present embodiment is not limited to the tightening rope 131, it can be any component for moving the support module 11 on the scalp, as long as it is of an integrated structure with the support module 11, which is within the protection scope of the present patent, and will not be described in more details herein.

[0070] In some embodiments, the tension adjustment module 13 can comprise at least one first force applying unit and at least one second force applying unit. The at least one first force applying unit is used to apply an action force of the support module 11 towards the scalp, so as to fasten the fixing module 12 on the scalp. The at least one second force applying unit is connected to the support module 11, and when the fixing module 12 is fastened on the scalp, the at least one second force applying unit is used to move the support module 11 on the scalp, so as to switch the support module 11 from the first position on the scalp to the second position.

[0071] In the present embodiment, the first force applying unit can comprise any component or device for applying an action force of the support module 11 towards the scalp, that is to say, the first force applying unit only needs to ensure that it can provide sufficient pressing force, so as to ensure that the support module 11 is always in close contact with the scalp during the movement of the support module 11 on the scalp by the second force applying unit, and will not fall off from the scalp.

[0072] For example, the first force applying unit can comprise an electric telescopic rod, a support can be arranged beside the seat, the driving end of the electric telescopic rod can be slidably arranged on the support, and the support module 11 is fixed to the free end of the telescopic shaft of the electric telescopic rod. In this way, during the pressing of the support module 11, the electric telescopic rod can also slide on the support along the pulling direction of the second force applying unit, so as to realize the movement of the support module 11 on the scalp in the pressed state, and finally realize the tensioning of the scalp. Of course, the electric telescopic rod is only a preferred example, the first force applying unit can comprise any component or device that can provide pressing force of the support module 11, such as a pneumatic cylinder, and the number of the first force applying unit can comprise one or more, which will not be limited herein. Further, the second force applying unit can comprise a pulling rope or any component or device for transverse traction, which will not be limited herein, and is within the protection scope of the present patent.

[0073] In some embodiments, referring to Figure 4 and Figure 5, the tightness adjusting module 13 can include a multi-axis mechanical arm 132. Wherein, the multi-axis mechanical arm 132 forms a docking end at the end, the docking end is used to dock the support module 11, the multi-axis mechanical arm 132 is used to apply the action force of the support module 11 to the scalp direction, so as to fasten the fixing module 12 on the scalp, and drive the support module 11 to move on the scalp, so as to switch the support module 11 at the first position of the scalp to the second position.

[0074] In this embodiment, the multi-axis mechanical arm 132 plays a dual role of synchronously driving the support module 11 to press the scalp and driving the support module 11 to move on the scalp. By providing sufficient pressure to the support module 11, it is ensured that the support module 11 is always in close contact with the scalp during the movement of the multi-axis mechanical arm 132, and will not fall off the scalp.

[0075] Specifically, the multi-axis mechanical arm 132 can be controlled by a controller, which controls the movement of the multi-axis mechanical arm 132 based on the attitude information of the support module 11 on the scalp, so as to control the multi-axis mechanical arm 132 to press the scalp and drive the support module 11 to move on the scalp in real time, and finally realize the tensioning of the scalp. As a preferred example of this embodiment, the multi-axis mechanical arm 132 can be a multi-axis serial mechanical arm, such as a five-axis, six-axis, seven-axis, etc. The number of axes of the multi-axis mechanical arm 132 can be flexibly selected according to actual use requirements. The multi-axis serial mechanical arm can be coupled through multiple joints to provide upward and downward movement (along the Z axis), forward and backward movement (along the Y axis), left and right movement (along the X axis), rotation around the X axis, rotation around the Y axis, and rotation around the Z axis. This design structure can enable the multi-axis serial mechanical arm to perform complex movements in three-dimensional space, thereby achieving more accurate and efficient operation. Based on the coupling of the above-mentioned joints, the support module 11 installed on the docking end can be adjusted in any attitude and position in space, and continuous reachability of the support module 11 in any attitude can be realized, so that under the control of the controller, the multi-axis serial mechanical arm can ensure that the support module 11 is accurately and correctly closely attached to the scalp and moves on the scalp, so as to realize the tensioning of the scalp.

[0076] Of course, in this embodiment, the multi-axis mechanical arm 132 is not limited to the multi-axis serial mechanical arm configuration, but can also be, for example, a da Vinci parallelogram configuration or a track-type motion configuration, all of which are within the protection scope of this patent.

[0077] Further, in the embodiment, the fixing module 12 can include at least one of a pin, a barb, a micro barb, a soft glue layer or a fixed layer with a concave-convex surface arranged on the action surface 112. The pin, the barb and the micro barb are arranged to penetrate into the surface of the scalp to achieve close contact between the support module 11 and the scalp, so that the hooked part of the scalp can move on the scalp together with the support module 11. Of course, since the multi-axis mechanical arm 132 provides the pressing force of the support module 11 on the scalp, the soft glue layer or the fixed layer with a concave-convex surface can also be used to achieve close contact between the support module 11 and the scalp, so that the glued part of the scalp can move on the scalp together with the support module 11. Therefore, the fixed form by friction is also within the protection scope of the patent.

[0078] Further, in the embodiment, referring to Figure 8 , in order to make the support module 11 better match the contour of the scalp, the docking end of the multi-axis mechanical arm 132 can be provided as a spherical hinge head 1321, and a ball groove for embedding the spherical hinge head 1321 can be arranged on the clamping part 111 of the support module 11. Through the nesting cooperation of the spherical hinge head 1321 and the ball groove, the adjustment of the support module 11 in any direction relative to the docking end can be achieved, thereby greatly improving the matching effect of the support module 11 and the contour of the scalp.

[0079] The application also provides a scalp tensioning mechanism 20 in the second aspect, which can specifically include at least two scalp tensioning devices 10 arranged on the scalp for fixed connection with the scalp. The scalp tensioning device 10 is the scalp tensioning device 10 provided in the first aspect of the application.

[0080] Specifically, referring to Figure 6 and Figure 7 , two scalp tensioning devices 10 can be arranged around the scalp area where the hair follicles are to be extracted, and the pulling forces of the scalp tensioning devices 10 are synchronously applied to make the scalp tensioning devices 10 move away from each other, so as to finally achieve the tensioning of the scalp area where the hair follicles are to be extracted. Therefore, the scalp tensioning device 10 of the patent has a wide range of application scenarios and can adapt to different hair follicle extraction procedures. Of course, in the embodiment, three, four or five scalp tensioning devices 10 can also be arranged around the scalp area where the hair follicles are to be extracted, which are also within the protection scope of the patent, and will not be described in detail here.

[0081] Of course, in some embodiments, referring to Figure 9 , the scalp expansion mechanism can also include a tensioning body 21, and the at least two scalp tensioning devices 10 are connected to the tensioning body 21 for fixed connection with the scalp.

[0082] Preferably, the tensioning body 21 can be deformed, so that the overall structure of the scalp tensioning device 10 is more stable, and the fit between the at least two scalp tensioning devices 10 and the scalp can be improved, and the local buckling between the support module 11 and the scalp can not occur.

[0083] In this embodiment, the tensioning body 21 can be preferably made of an annular band with elasticity, for example, made of an elastic material such as silicone or rubber. In this way, when the at least two scalp tensioning devices 10 are fitted to the scalp, the tensioning body 21 not only connects the at least two scalp tensioning devices 10 to form a whole, but also deforms, stretches and rebounds along the contour of the scalp, ensuring that the at least two scalp tensioning devices 10 can be accurately fitted to the designated hair follicle extraction area of the scalp and can tension the scalp. Of course, the annular band structure of the tensioning body 21 also allows it to be arranged around the edge of the scalp area where the hair follicles are to be extracted, so that the scalp tensioning device 10 does not interfere with the entire hair follicle extraction operation.

[0084] As a preferred scheme of this embodiment, referring to Figure 9 In order to facilitate the scalp tensioning device 10 to be quickly assembled and disassembled with the tensioning body 21, the clamping portion 111 provided on the support module 11 can further include a second clamping groove 1112. The second clamping groove 1112 can be preferably provided on the same face of the support module 11 as the first clamping groove 1111, and oppositely arranged. That is, the second clamping groove 1112 can be provided on the other side edge position opposite to the first clamping groove 1111, and the second clamping groove 1112 can be preferably integrally formed with the support module 11. The integral structure not only can improve the stability of the structure of the second clamping groove 1112, but also the second clamping groove 1112 has the same slight elasticity as the support module 11, facilitating the installation and disassembly of the tensioning body 21, but not limited thereto.

[0085] Specifically, referring to Figure 9 The number of the second clamping groove 1112 on each support module 11 can be two, and the two second clamping grooves 1112 are arranged on opposite sides of the edge of the support module 11 along the length direction thereof. The second clamping groove 1112 is internally provided with a receiving portion, and the upper end face thereof is provided with an opening leading to the receiving portion. The contour of the receiving portion is matched with the cross section of the tensioning body 21, and the width of the opening is smaller than the diameter of the tensioning body 21. In this way, when the tensioning body 21 is clamped into the receiving portion from the opening, the tensioning body 21 will not be detached from the second clamping groove 1112 when the scalp tensioning device 10 is pulled, effectively ensuring that the at least two scalp tensioning devices 10 are always in a complete state with the tensioning body 21.

[0086] It is worth mentioning that in the embodiment, the number of the scalp tensioning devices 10 can be two, three, four or five, and the specific number can be flexibly selected according to actual use requirements, and all are within the protection scope of the patent. For example, when the number of the scalp tensioning devices 10 is three, the three scalp tensioning devices 10 are respectively arranged at intervals and connected to the circumferential edge of the tensioning main body 21, and the tensioning adjustment modules 13 of the three scalp tensioning devices 10 respectively apply force to the corresponding support modules 11, so that the three scalp tensioning devices 10 drive the scalp adhered thereto to move away from each other, at this time, the tensioning main body 21 expands due to deformation, so that the area of the scalp tensioning area is expanded, and finally the tensioning effect of the scalp area where the hair follicles are to be extracted is achieved. Of course, the above is only a preferred example, and is not limited thereto.

[0087] The embodiment of the present application also provides a hair follicle transplantation robot in the third aspect, which can specifically include a seat, a hair follicle extraction mechanism and a scalp tensioning mechanism 20. The seat can be used to carry a hair follicle transplantation patient, and the seat is provided with a tension adjustment module 13. When the tension adjustment module 13 makes the scalp in a tension state, the hair follicle extraction mechanism is used to extract hair follicles on the scalp in the tension state. The scalp tensioning mechanism 20 is the scalp tensioning mechanism 20 provided in the second aspect of the embodiment of the present application.

[0088] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
