[0049] DETAILED DESCRIPTION
[0050] 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 but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.
[0051] 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 "comprise" 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 inclusions without exclusivity.
[0052] 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 and are not intended to describe a specific order or primary and secondary relationship.
[0053] 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.
[0054] Referring to Figures 1 to 4 In a first aspect, the embodiments of the present application provide a scalp expansion module, which specifically comprises a support body 11, an adhesive unit 12 and at least one position adjusting unit. The adhesive unit 12 is arranged on the support body 11, and the adhesive unit 12 and the scalp are bonded to fix the support body 11 and the scalp. The position adjusting unit is connected to the support body 11, and the position adjusting unit drives the support body 11 to move on the scalp to move the support body 11 from an initial position of the scalp to a preset position.
[0055] The scalp expansion module provided by the embodiment of the application is characterized in that the adhesive unit 12 is arranged on the support body 11, and the adhesive unit 12 is used to adhere to the scalp area from which hair follicles are to be extracted, so that the support body 11 and the scalp can be fixed. Compared with the prior art of hooking the scalp by using, for example, a micro barb, the adhesive mode is convenient to use and has high firmness, so that the support body 11 and the scalp can be effectively adhered and fixed, and the scalp is not damaged, thereby greatly improving the comfort experience of the patient during the operation. Meanwhile, under the adhesion of the adhesive unit 12, sufficient adhesion force can be provided, so that the support body 11 is always in a state of being closely adhered to the scalp during the movement of the support body 11 on the scalp driven by the position adjusting unit to move the support body 11 from the initial position of the scalp to the preset position, and the support body 11 will not fall off from the scalp. The connection and cooperation of the adhesive unit 12 and the position adjusting unit can effectively tension the scalp during the extraction of the hair follicles and improve the comfort experience of the patient during the operation, and the structure and operation are simple, the cost is low, and the application range is wide.
[0056] In some embodiments, the support body 11 is used as a carrier, which is preferably made of a material with micro elasticity, so that the support body 11 will not be hard pulled and interfered with the scalp during the movement of the support body 11 on the scalp driven by the position adjusting unit, and the slight deformation of the support body 11 during the movement can ensure that the support body 11 is closely attached to the scalp, so that the scalp tensioning effect and the use experience of the patient can be improved. As preferred, the support body 11 can be made of a plastic material with micro elasticity, which can integrate support and deformation. Of course, the support body 11 of the embodiment can also be made of other materials, which are not limited here, and the specific material can be flexibly selected according to the actual situation of the patient, which is within the protection scope of the patent and will not be described in detail here.
[0057] Of course, the structure of the support body 11 in the embodiment can also be flexibly selected according to the actual situation of the patient, for example, the support body 11 can be in the form of a long strip-shaped plate, and the position adjusting unit can exert a force perpendicular to the length direction of the support body 11, so that the area of the scalp tensioning area can be effectively expanded, thereby reducing the number of times of scalp tensioning and improving the efficiency of hair follicle extraction.
[0058] Further, the edge of the support body 11 can be designed with a circular arc chamfer, so that the probability of damage to the scalp caused by interference between the support body 11 and the scalp can be effectively reduced, and the appearance is high.
[0059] In some embodiments, referring to Figure 4The adhesive unit 12 comprises an adhesive layer 121 arranged on the support body 11 to be adhered to the scalp. Of course, since the scalp is not a complete plane but has a certain curvature, especially when the hair follicle extraction area is larger, the curvature is larger. Therefore, in order to make the adhesive layer 121 and the scalp have better fit, the adhesive unit 12 can further comprise a deformation layer 122. The support body 11 has an action surface 111, one side of the deformation layer 122 is adhered to the action surface 111, and the adhesive layer 121 is adhered to the other side of the deformation layer 122.
[0060] Specifically, referring to Figure 4 The action surface 111 can be directly formed on one end surface of the support body 11, which can be preferably arc-shaped concave, and the profile of the arc-shaped concave surface is adapted to the scalp. The deformation layer 122 can be preferably made of flexible and recoverable material, such as foam, but is not limited thereto. When the deformation layer 122 is attached to the action surface 111, the deformation layer 122 also presents an arc shape with consistent curvature under the constraint of the arc angle of the action surface 111. Then, by adhering the adhesive layer 121 to the side of the deformation layer 122 opposite to the action surface 111, the adhesive unit 12 and the support body 11 can be adhered and fixed. Under the deformation of the deformation layer 122, the adhesive layer 121 can adaptively change shape according to the profile of the patient's scalp, effectively ensuring that the support body 11 can better fit the scalp, has better stability, and greatly improves the comfort experience of the patient wearing.
[0061] It is worth mentioning that the thickness of the deformation layer 122 can be flexibly adjusted according to the actual use scene, and two or more deformation layers 122 can be integrated in a stacked form, all of which are within the protection scope of the present patent.
[0062] More worth mentioning is that the deformation layer 122 and the adhesive layer 121 are preferably covered on the entire area of the action surface 111, which can effectively increase the area of the support body 11 acting on the scalp, thereby improving the tightness of the fit and further improving the scalp tension effect.
[0063] It is also worth mentioning that when the scalp expansion module 10 is in an unused state, in order to prevent the adhesive layer 121 from being contaminated by dust and dirt, thereby causing the scalp expansion module 10 to be scrapped, a protective film can be preferably attached to the side of the adhesive layer 121 opposite to the deformation layer 122. During the hair follicle extraction and transplantation surgery, the doctor can manually tear off the protective film to adhere the scalp expansion module 10 to the scalp, which can greatly improve the cleanliness of the surgery and the tension effect of the scalp.
[0064] Further, as a preferred example of the present embodiment, the adhesive layer 121 and the deformation layer 122 can be designed in one piece, that is, one side of the deformation layer 122 is directly bonded to the action surface 111 of the support body 11, and the other side of the deformation layer 122 is coated with glue to directly form the adhesive layer 121. Of course, as another preferred example of the present embodiment, the adhesive layer 121 and the deformation layer 122 can be designed in separate pieces and bonded, which is also within the protection scope of the present patent.
[0065] In some embodiments, referring to Figures 2 to 4 , the side of the support body 11 opposite to the adhesive unit 12 is provided with at least one clamping portion 112 for docking a position adjusting unit. As a preference, the position adjusting unit includes a buckle rope 13, one end of which is buckled to the clamping portion 112, and the other end is connected and fixed to other devices, so as to maintain the support body 11 on the scalp in a preset position, so that the scalp is tightly stretched under the action of the support body 11.
[0066] As a preference, the buckle rope 13 can be made of elastic material or plastic material or fiber material or metal material, for example, the buckle rope 13 can be made of silicone, rubber or other elastic material, which can be stretched and rebounded, and is convenient to be connected and fixed to other devices with different distances. For another example, the buckle rope 13 can also be made of nylon, metal or other materials, which can also provide a downward pressure of the support body 11 during stretching, further improving the tightness of the support body 11 and the scalp.
[0067] As a further preference, one end of the buckle rope 13 is buckled to the clamping portion 112, and the other end can be directly connected and fixed to other devices, such as a seat for bearing the patient, so as to maintain the support body 11 on the scalp in a preset position, so that the scalp is tightly stretched under the action of the support body 11. Of course, if the seat is used to dock the position of the buckle rope 13 which is far away from the scalp of the patient, a rope component such as a pull rope, a buckle belt or a tie belt can also be added to connect the buckle rope 13 and the seat, so as to realize the fixation of the buckle rope 13 and the seat, which is also within the protection scope of the present patent, and will not be described in detail here.
[0068] Further, referring to Figure 3 , in order to facilitate the buckle rope 13 to be quickly assembled and disassembled with the clamping portion 112, the clamping portion 112 can include a first clamping groove 1121, which can be preferably arranged at the edge position of the side of the support body 11 opposite to the adhesive unit 12, and the first clamping groove 1121 can be preferably integrally formed with the support body 11. The integral structure not only can improve the stability of the structure of the first clamping groove 1121, but also the first clamping groove 1121 has the same slight elasticity as the support body 11, which is convenient for the buckle rope 13 to be installed and disassembled, but is not limited thereto.
[0069] In detail, referring toFigure 4 The number of the first clamping grooves 1121 can be two, and the two first clamping grooves 1121 are arranged on opposite sides of the lengthwise edge of the support body 11. The first clamping groove 1121 is internally provided with a receiving portion, and the upper end face of the receiving portion is provided with an opening for guiding the receiving portion. The clamping rope 13 can preferably have a ring-shaped rope structure. The contour of the receiving portion is matched with the cross section of the clamping rope 13, and the width of the opening is smaller than the diameter of the clamping rope 13. In this way, when the clamping rope 13 is clamped into the receiving portion from the opening, the clamping rope 13 will not be detached from the first clamping groove 1121 when a tensioning force is applied to the clamping rope 13 to pull the scalp.
[0070] In the embodiment, the number of the clamping rope 13 can be one, and the clamping rope 13 is clamped into the two first clamping grooves 1121 to fix the clamping rope 13 and the support body 11. Of course, the number of the clamping rope 13 can also be two, and the two clamping ropes 13 are sequentially clamped into the two first clamping grooves 1121, which 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 grooves 1121 and the clamping rope 13, and only needs to ensure that the position adjusting unit can drive the support body 11 to move on the scalp after being connected to the support body 11. In the process of moving the support body 11 at the initial position of the scalp to the preset position, the support body 11 is always in a state of being tightly bonded to the scalp and will not fall off the scalp.
[0071] It is worth mentioning that, in the embodiment, the clamping mode of the clamping rope 13 and the first clamping groove 1121 can facilitate the disassembly and replacement of the clamping rope 13 or the support body 11, and improve the convenience of the scalp expansion module 10 in actual use.
[0072] Of course, in some embodiments, the support body 11 and the at least one position adjusting unit can also have an integrated structure. For example, when the position adjusting unit includes a ring-shaped clamping rope 13, the support body 11 can be formed by extending the clamping rope 13 outward in a partial region, that is, the support body 11 and the clamping rope 13 are integrally injection molded. Such a structure can make the stability of the two stronger and effectively ensure that the clamping rope 13 can provide sufficient force to drive the support body 11 to move on the scalp. Of course, the position adjusting unit of the present embodiment is not limited to the clamping rope 13, and can be any member for driving the support body 11 to move on the scalp, as long as it has an integrated structure with the support body 11, which is within the protection scope of the present patent and will not be described in detail here.
[0073] The scalp expansion module 10 provided by the embodiment can be used independently, or can be used in cooperation with multiple scalp expansion modules 10, and can be flexibly selected according to actual use requirements. For example, one scalp expansion module 10 can be selected to be bonded with the edge of the scalp area where the hair follicle is to be extracted, and then a pulling force in a certain direction of the scalp expansion module 10 is applied, so that the scalp expansion module 10 drives the scalp bonded therewith to move, and finally the tension of the scalp area where the hair follicle is to be extracted is realized. For another example, two or more than two scalp expansion modules 10 can be selected to be arranged around the scalp area where the hair follicle is to be extracted, and the pulling forces of the scalp expansion modules 10 are synchronously applied, so that the scalp expansion modules 10 move away from each other, and finally the tension of the scalp area where the hair follicle is to be extracted can also be realized. Therefore, the scalp expansion module 10 of the patent has a wide use scenario and can adapt to different hair follicle extraction procedures.
[0074] Referring to Figures 5 to 8 In a second aspect, the embodiment of the application further provides a scalp expansion mechanism 20, which can specifically include an expansion main body 21 and at least two scalp expansion modules 10 disclosed in the first aspect. The at least two scalp expansion modules 10 are connected to the expansion main body 21 and are used to be fixedly connected with the scalp.
[0075] Preferably, the expansion main body 21 can be deformed, so that the overall structure of the scalp expansion mechanism 20 is more stable, and the fit between the at least two scalp expansion modules 10 and the scalp can be improved, so that the local lifting between the scalp expansion modules 10 and the scalp does not occur.
[0076] In the embodiment, the expansion main body 21 can be preferably made of a ring-shaped belt with elasticity, for example, made of an elastic material such as silica gel or rubber. In this way, when the at least two scalp expansion modules 10 are bonded with the scalp, the expansion main body 21 not only connects the at least two scalp expansion modules 10 to form a whole, but also deforms, stretches and rebounds along the contour of the scalp, so that the at least two scalp expansion modules 10 can be accurately bonded to the designated hair follicle extraction area of the scalp and the tension of the scalp can be realized. Of course, the ring-shaped belt structure of the expansion main body 21 also enables it to be arranged around the edge of the scalp area where the hair follicle is to be extracted, so that the scalp expansion mechanism 20 does not interfere with the entire hair follicle extraction operation process.
[0077] As a preferred scheme of the embodiment, referring to Figure 6In order to facilitate the head skin expansion module 10 to be quickly assembled and disassembled with the expansion body 21, the clamping portion 112 arranged on the support body 11 can further comprise a second clamping groove 1122, which can be preferably arranged on the same face of the support body 11 as the first clamping groove 1121 and oppositely arranged. That is to say, the second clamping groove 1122 can be arranged at the other side edge position opposite to the first clamping groove 1121, and the second clamping groove 1122 can be preferably integrally formed with the support body 11. The integral structure can not only improve the stability of the structure of the second clamping groove 1122, but also has the same slight elasticity as the support body 11, so as to facilitate the installation and disassembly of the expansion body 21, but is not limited thereto.
[0078] Specifically, referring to Figure 6 The number of the second clamping grooves 1122 on each support body 11 can be two, and the two second clamping grooves 1122 are arranged at opposite sides of the edge of the support body 11 along the length direction thereof. The second clamping groove 1122 is internally provided with a receiving portion, and the upper end face thereof is provided with an opening for guiding the receiving portion. The contour of the receiving portion is matched with the cross section of the expansion body 21, and the width of the opening is smaller than the diameter of the expansion body 21. In this way, when the expansion body 21 is clamped into the receiving portion from the opening, the expansion body 21 will not be separated from the second clamping groove 1122 when the head skin expansion module 10 is pulled, so as to effectively ensure that at least two head skin expansion modules 10 are always in a complete state with the expansion body 21.
[0079] It is worth mentioning that, in the present embodiment, referring to Figures 5 to 8 The number of the head skin expansion modules 10 can be two, three, four or five, and the specific number can be flexibly selected according to actual use requirements, which is within the protection scope of the present patent. For example, when the number of the head skin expansion modules 10 is three, the three head skin expansion modules 10 are arranged at intervals and connected to the circumferential edge of the expansion body 21. The position adjusting units of the three head skin expansion modules 10 apply force to the corresponding support bodies 11, so that the three head skin expansion modules 10 drive the head skin bonded thereto to move away from each other. At this time, the expansion body 21 is expanded due to deformation, so that the area of the head skin tension area is expanded, and finally the tension effect of the head skin area to be extracted is achieved. Of course, the above is only a preferred example, and is not limited thereto.
[0080] The embodiment of the present application also provides a hair follicle extraction device in the third aspect, and specifically can include a seat, a hair follicle extraction mechanism and a scalp expansion mechanism 20. The seat can be used to carry a hair follicle transplant recipient, and at least one position adjusting unit is arranged on the seat. When the position adjusting unit drives the support body 11 to move to a preset position of the scalp, the hair follicle extraction mechanism is used to extract hair follicles on the scalp in a tense state. The scalp expansion mechanism 20 is the scalp expansion mechanism 20 provided in the second aspect of the embodiment of the present application.
[0081] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the present application. 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.
