[0039] Example

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 and Fig.10 As shown, a hair follicle extraction device of a hair transplant robot comprises a bed 1, a support plate 2 is fixedly connected to one side of the bed 1, a placement frame 99 is provided on the support plate 2, an extraction unit 3 is provided on the placement frame 99, the extraction unit 3 is used to separate hair follicles on the scalp, a suction unit 4 is provided in the extraction unit 3, a collection unit 5 is also provided in the extraction unit 3, the suction unit 4 sucks the hair follicles into the collection unit 5 for storage, the collection unit 5 is provided with a rotation unit 6 for driving the rotation thereof, and the collection unit 5 is provided with a moisturizing unit 7 for maintaining the activity of the hair follicles;

[0041] The collecting unit 5 comprises a No. 1 fixing frame 55, a No. 2 fixing frame 56 is provided on one side of the No. 1 fixing frame 55, a No. 2 winding roller 53 and a No. 1 winding roller 52 are respectively sleeved on the No. 1 winding roller 52 and the No. 2 winding roller 53, and biological cotton 51 for collecting hair follicles is sleeved on the No. 1 winding roller 52 and the No. 2 winding roller 53;

[0042] The convex strip 54 is fixedly connected to the bottom end of the second winding roller 53 , and a clamping groove 57 is provided on the first fixing frame 55 , and the convex strip 54 is clamped with the clamping groove 57 .

[0043] In the embodiment, before taking the hair follicles, the outer shell 31 is first opened, and then the No. 1 winding roller 52 is mounted on the No. 2 fixing frame 56, and the No. 2 winding roller 53 is mounted on the No. 1 fixing frame 55. It should be noted that a convex strip 54 is provided at the bottom of the No. 2 winding roller 53, and the convex strip 54 needs to be snapped into the card slot 57 so that the No. 1 fixing frame 55 can subsequently drive the No. 2 winding roller 53 to rewind the biological cotton 51.

[0044] It should be understood that in the initial state, the biological cotton 51 is wound around the No. 1 winding roller 52, and the biological cotton 51 is not wound around the No. 2 winding roller 53. One end of the biological cotton 51 is only connected to the No. 2 winding roller 53. After the No. 2 winding roller 53 rotates, the biological cotton 51 on the No. 1 winding roller 52 will be slowly wound around itself.

[0045] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the extraction unit 3 includes a shell 31, the shell 31 is located on the placement rack 99, a cavity 35 is provided in the shell 31, a partition 34 is provided in the cavity 35, and the partition 34 divides the cavity 35 into two parts. A needle 32 is fixedly connected to the head of the shell 31, and the needle 32 is a hollow needle tube;

[0046] One end of the housing 31 away from the needle 32 is fixedly connected to an air pump 33 through a catheter, and the air pump 33 is fixedly connected to the support plate 2;

[0047] The suction unit 4 includes a sliding frame 41, which is fixedly connected to a side of the partition 34 close to the needle 32, a sealing plate 42 is slidably connected inside the sliding frame 41, the sealing plate 42 and the partition 34 are slidably fitted, a plurality of support springs 45 are fixedly connected to one end of the sealing plate 42, the other end of the support spring 45 is fixedly connected to one end of the sliding frame 41, and a push-pull plate 44 is fixedly connected to one end of the sealing plate 42 away from the support spring 45, and one end of the push-pull plate 44 slides through the shell 31 and extends to the outside of the shell 31;

[0048] The sealing plate 42 is provided with a through hole 43 , and the partition plate 34 is provided with an air hole 46 . The through hole 43 and the air hole 46 cooperate with each other. When the through hole 43 and the air hole 46 overlap, the cavity 35 , the needle 32 and the air pump 33 are connected.

[0049] In the embodiment, when extracting hair follicles, the user first holds the shell 31 so that the needle 32 is aligned with the hair follicle, and then pushes the shell 31 so that the needle 32 penetrates the skin around the hair follicle, and then uses the thumb to press the push-pull plate 44. After the push-pull plate 44 is pressed, the push-pull plate 44 drives the sealing plate 42 to move toward the support spring 45, and the support spring 45 is compressed at the same time. During this process, the sealing plate 42 drives the through hole 43 and the air hole 46 on the partition 34 to overlap. At this time, due to the suction of the air pump 33, the entire cavity 35 is under negative pressure. At this time, the hair follicles are sucked into the cavity 35 through the needle 32 and then adhere to the biological cotton 51. When the thumb releases the push-pull plate 44, the support spring 45 extends, driving the sealing plate 42 to slide and reset on the sliding frame 41, and then the user can take the next hair follicle.

[0050] like Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the rotating unit 6 includes a connecting plate 61, the connecting plate 61 is fixedly connected to the push-pull plate 44, a rack 62 is fixedly connected to the connecting plate 61, a gear 63 is rotatably connected to the bottom end of the inner wall of the outer shell 31, the rack 62 and the gear 63 are meshed, a main shaft 64 is fixedly connected to the upper end face of the gear 63, a one-way bearing 65 is fixedly connected to the main shaft 64, a belt 66 is nested on the one-way bearing 65, a turntable 67 is fixedly connected to the No. 1 fixed frame 55, and the turntable 67 is rotatably connected through the belt 66 and the one-way bearing 65.

[0051] In the embodiment, when the user repeatedly presses the push-pull plate 44, the rack 62 is driven to move repeatedly, the rack 62 drives the gear 63 to rotate repeatedly, the gear 63 drives the main shaft 64 to rotate repeatedly, and the main shaft 64 drives the turntable 67 to rotate continuously in the same direction through the belt 66 under the action of the one-way bearing 65 (the one-way bearing 65 is the prior art, and when the main shaft 64 rotates back and forth, the one-way bearing 65 will only rotate in one direction). When the turntable 67 rotates continuously, it will drive the No. 2 winding roller 53 on the No. 1 fixed frame 55 to rotate, and when the No. 2 winding roller 53 rotates, it will wrap the upper biological cotton 51 of the No. 1 winding roller 52 around itself little by little.

[0052] It should be noted that when the second winding roller 53 rotates, it will wind the upper biological cotton 51 of the first winding roller 52 around itself little by little. In this process, the hair follicles will continue to be sucked into the cavity 35 through the needle 32, and then adhere to the biological cotton 51. The biological cotton 51 is in a slowly moving state at this time, which can prevent the hair follicles from concentrating and adhering to the same position of the biological cotton 51, avoiding the mess of the hair follicles on the biological cotton 51, thereby facilitating subsequent users to collect hair follicles from the biological cotton 51 and improving work efficiency.

[0053] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the moisturizing unit 7 includes a liquid storage box 71, which is filled with hair follicle nutrient solution. The liquid storage box 71 is fixedly connected to the partition 34, and one end of the liquid storage box 71 close to the second fixing frame 56 is fixedly connected to a spring tube 72 with adjustable direction, and the end of the spring tube 72 is fixedly connected to a sponge head 73 for the hair follicle nutrient solution to flow slowly, and the sponge head 73 is in contact with the biological cotton 51 on the first winding roller 52.

[0054] In the embodiment, when the No. 1 winding roller 52 on the No. 2 fixing frame 56 is pulled and rotated, since the sponge head 73 is in contact with the biological cotton 51 on the No. 1 winding roller 52 and the No. 1 winding roller 52 rotates slowly, the hair follicle nutrient solution on the biological cotton 51 will continue to moisten the biological cotton 51 to maintain the activity of the hair follicles on the biological cotton 51.

[0055] The workflow is as follows:

[0056] Before removing hair follicles, the user first opens the shell 31, then sets the No. 1 winding roller 52 on the No. 2 fixing frame 56, and at the same time snaps the convex strip 54 on the No. 2 winding roller 53 into the slot 57, sets the No. 2 winding roller 53 on the No. 1 fixing frame 55, and then closes the shell 31. When extracting hair follicles, the user first holds the shell 31 so that the needle 32 is aligned with the hair follicle, then pushes the shell 31 so that the needle 32 penetrates the skin around the hair follicle, and then uses the thumb to press the push-pull plate 44. After the push-pull plate 44 is pressed, the push-pull plate 44 drives the sealing plate 42 to move toward the support spring 45, and the support spring 45 is compressed. During this process, the sealing plate 42 drives the through hole 43 and the air hole 46 on the partition 34 to overlap. At this time, due to the suction of the air pump 33, the entire cavity 35 is under negative pressure. At this time, the hair follicle is sucked into the cavity 35 through the needle 32 and then adheres to the biological cotton 51. When the thumb releases the push-pull plate 44, the support spring 45 extends, driving the sealing plate 42 to slide and reset on the sliding frame 41, and then the user can take the next hair follicle. When the user repeatedly presses the push-pull plate 44, the rack 62 is driven to move repeatedly, the rack 62 drives the gear 63 to rotate repeatedly, the gear 63 drives the main shaft 64 to rotate repeatedly, and the main shaft 64 drives the turntable 67 to rotate continuously in the same direction through the belt 66 under the action of the one-way bearing 65. When the turntable 67 rotates continuously, it drives the No. 2 winding roller 53 on the No. 1 fixing frame 55 to rotate. When the No. 2 winding roller 53 rotates, it will wrap the upper biological cotton 51 of the No. 1 winding roller 52 around itself little by little. In this process, the hair follicles will continue to be sucked into the cavity 35 through the needle 32, and then adhere to the biological cotton 51. The biological cotton 51 is in a slowly moving state at this time, which can prevent the hair follicles from concentrating and adhering to the same position of the biological cotton 51, avoiding the mess of the hair follicles on the biological cotton 51, thereby facilitating subsequent users to collect hair follicles from the biological cotton 51 and improving work efficiency. Since the sponge head 73 is in contact with the biological cotton 51 on the first winding roller 52 and the first winding roller 52 rotates slowly, the hair follicle nutrient solution on the biological cotton 51 will continue to moisten the biological cotton 51 to maintain the activity of the hair follicles on the biological cotton 51 .
