[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0051] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0052] Please refer to Figure 1 and Figure 2 As shown, this embodiment discloses a device for picking up and implanting hair follicles, comprising:
[0053] Handheld part 1, connector 2, tail connecting block 3, slider 4, spring 5, and needle body 6;
[0054] The handle 1 is a hollow cylindrical structure with an internal through-axis, and the inner sides of both ends are provided with threads. The connector 2 and the tail connector 3 are respectively threaded to both ends of the handle 1.
[0055] The slider 4 is slidably installed in the handheld part 1, and the spring 5 is elastically connected between the slider 4 and the tail connecting block 3, thereby pushing the slider 4 to one end of the connector 2, thus forming a cavity between the slider 4 and the tail connecting block 3.
[0056] The connector 2 and the tail connector 3 are respectively provided with a first through hole and a second through hole along the transverse axis. The second through hole communicates with the chamber. The side of the connector 2 is also provided with a third through hole, which communicates with the first through hole.
[0057] The needle body 6 includes an outer needle 61 and an inner needle 62. The outer needle 61 is fixed in the first through hole, and the inner needle 62 is fixedly installed in the first through hole located at the front end of the connector 2. One end of the inner needle 62 is fixedly connected to the slider 4, and the other end extends through the first through hole into the outer needle 61.
[0058] Specifically, the hand-held part 1 is a hollow cylindrical structure with an internal through-hole along the axial direction, and the inner sides of both ends are provided with threads. The connector 2 and the tail connector 3 are respectively threaded to both ends of the hand-held part 1.
[0059] According to the above embodiments of the present invention, the device can achieve contactless hair follicle pickup and implantation, avoiding physical contact, helping to reduce the risk of hair follicle damage and injury, improving the survival rate of hair follicles, improving the implantation effect, and reducing the workload of physicians.
[0060] like Figure 3 As shown, connector 2 is a fully transparent structure with a pointed tip and a threaded tail. It has a through hole on the transverse axis, which includes a long diameter section and a short diameter section. Connector 2 also has a third through hole on one side, wherein the third through hole is connected to the short diameter section of the first through hole.
[0061] As shown in Figures 4(a) and 4(b), the tail connecting block 3 includes a fixing member 31, a threaded shaft 32, and a rotating component 33;
[0062] One end of the fixing member 31 is threaded to the hand-held part 1, and the other end is snapped with the rotating part 33. The threaded shaft 32 passes through the middle of the fixing member 31 and is threadedly engaged with the rotating part 33. The second through hole passes through both ends of the threaded shaft 32 laterally along its axis. The length of the chamber is adjusted by rotating the rotating part 33 to control the lateral movement of the threaded shaft 32.
[0063] The slider 4 is slidably mounted in the handheld part 1. A spring 5 is installed between the slider 4 and the tail connecting block 3, thereby pushing the slider 4 to the rear end of the connector 2, thus forming a cavity between the slider 4 and the tail connecting block 3, which communicates with the second through hole; Figure 5 As shown, the slider 4 has grooves along the longitudinal direction on both sides and at least one groove along the circumference. There is a long cylindrical block in the groove. The long cylindrical block rolls elastically on the inner surface of the handheld part 1 and is fitted with an annular sealing strip. At the same time, the annular sealing strip is squeezed and slid on the inner surface of the handheld part 1. The slider 4 has a fourth through hole and a threaded groove on the transverse axis. The fourth through hole is connected to the first through hole.
[0064] like Figure 6 As shown, the needle body 6 includes an outer needle 61 and an inner needle 62. The outer needle 61 is fixed within the long diameter section of the first through hole and protrudes beyond the connector 2 with a flat end. The inner needle 62 is fixedly connected to the slider 4 and extends into the first through hole. Specifically, the inner needle 62 is fixed to a threaded connecting block, and the threaded connecting block is connected to the threaded groove, thereby fixing the inner needle 62 to the slider 4 and inserting it into the fourth through hole, and then extending into the interior of the first through hole. In this embodiment, the diameter of the first through hole and the outer needle 61 over its entire length is larger than the diameter of the inner needle 62, so that the inner needle 62 can pass through the first through hole and the outer needle 61 without contacting them. In this embodiment, the cross-section of the inner needle 62 is cross-shaped, polygonal, circular, star-shaped, or other shapes.
[0065] like Figure 7 As shown, this embodiment also includes a first vent pipe 7 and a second vent pipe 8. One end of the first vent pipe 7 is connected to the third through hole, and the other end is connected to the first negative pressure source through a filter bottle (not shown in the figure). One end of the second vent pipe 8 is connected to the second through hole, and the other end is connected to the second negative pressure source. The filter bottle is equipped with a barrier net, which can block scalp residue entering the filter bottle and prevent it from entering the negative pressure source.
[0066] like Figure 1 As shown, in this embodiment, when stationary, the slider 4 is pressed against the rear end of the connector 2 by the spring force. At this time, the inner needle 62 fixed inside the slider 4 extends through the fourth through hole and the first through hole until it is flush with the protruding end of the outer needle 61.
[0067] like Figure 8 As shown, this embodiment also discloses a method for a hair follicle pickup and implantation device, comprising the following steps:
[0068] S1. Scalp residue treatment: Bring the device close to the scalp residue and adjust the length of the chamber to the first length. Connect the first negative pressure source and the second negative pressure source respectively to draw the scalp residue into the filter bottle.
[0069] Specifically, during the scalp residue removal process, the second negative pressure source is activated, and the chamber is connected to the second negative pressure source through the second through hole and the second vent tube 8. At this time, a low pressure is generated in the chamber, causing the slider 4 to move a distance L1 (approximately equal to the length of the chamber) towards the front end of the tail connector 3, thereby driving the front end of the inner needle 62 to move a distance backward, so that the needle tip of the inner needle 62 moves to the rear of the third through hole (where L1 is greater than the distance L2 from the connection between the third through hole and the first through hole to the protruding end of the outer needle 61).
[0070] Then the first negative pressure source is turned on, and the first through hole is connected to the negative pressure source through the third through hole and the first air pipe 7. At this time, a low pressure is generated in the first through hole, which causes the scalp residue to enter the first through hole and the third through hole from the protruding end of the outer needle 61 and enter the filter bottle to complete the cleaning.
[0071] S2, hair follicle pickup: bring the device close to the hair follicle to be implanted, adjust the length of the chamber to the second length, and turn on the first negative pressure source and the second negative pressure source again to suck the hair follicle into the first through hole.
[0072] Specifically, during the hair follicle pickup action, the rotating component located at the tail connecting block 3 is rotated, causing the threaded shaft 32 in the tail connecting block 3 to move forward a distance L′, so that the chamber length is L1′=L1-L′. At this time, the second negative pressure source is turned on, causing the inner needle 62 to move backward a distance L1′ (where L1′ is less than L2), so that the front end of the inner needle 62 is in front of the third through hole. Then, the first negative pressure source is turned on, and the first through hole is connected to the negative pressure source through the third through hole and the first air tube 7. At this time, a low pressure is generated in the first through hole, causing the hair follicle to enter the outer needle 61 and the first through hole from the protruding end of the outer needle 61, thus completing the hair follicle pickup action. During the hair follicle picking action, the hair follicle is sucked into the first through hole and moves to the annular gap formed between the first through hole and the inner needle 62. Because the gap is small enough and the tip of the inner needle 62 is located in front of the third through hole, the inner needle 62 blocks the hair follicle and prevents the hair follicle from passing through the inner needle 62 and entering the third through hole, thus protecting the integrity of the hair follicle.
[0073] S3. Hair follicle implantation: Bring the device close to the scalp to be implanted, disconnect the first negative pressure source and the second negative pressure source, the spring 5 automatically resets, and drives the inner needle 62 to push the hair follicle located in the first through hole into the scalp to be implanted, thus completing the hair follicle implantation.
[0074] Specifically, during the hair follicle implantation process, the first negative pressure source and the second negative pressure source are disconnected simultaneously. The slider 4 moves a distance L1 under the action of the spring force and finally fits with the tail of the connector 2, thereby driving the inner needle 62 to move forward an equal distance, and thus pushing out the hair follicle in the first through hole.
[0075] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, because according to the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily essential to the present invention.
[0076] It should be understood that the various forms of processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this invention can be achieved, and this is not limited herein.
[0077] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
