[0052] Example 5

[0053] On the basis of Example 4, in order to solve the problem of replacing the hair retrieval punching needle 27, this embodiment provides a hair retrieval punching needle 27. The hair retrieval punching needle 27 is provided with an assist sleeve 273; the assist sleeve 273 and the hair retrieval punching needle 27 are fixedly connected. The assist sleeve 273 includes a protrusion 2731, an annular groove 2732 and a coaxial portion 2733; the annular groove 2732 is provided between the protrusion 2731 and the coaxial portion 2733. When the hair retrieval punching needle 27 is inserted into the hair retrieval device 2, the coaxial portion 2733 is inserted into the coaxial sleeve 282 and contacts the coaxial sleeve 282.

[0056] Example 6

[0057] On the basis of Embodiment 4 and Embodiment 5, in order to solve the problems of efficiency and degree of scalp damage during hair removal and perforation, this embodiment provides a hair removal perforation needle 27. The hair removal perforation needle 27 includes a needle head 271 and a needle body 272; the booster sleeve 273 is arranged on the needle body 272. The needle head 271 includes a cutting portion 2711, an expansion portion and a limiting portion 2713.

[0058] The inner diameter of the needle body 272 is 1.12-1.13 mm, and the outer diameter is 1.46-1.47 mm; the inner diameter of the needle head 271 is 0.55-0.85 mm. The outer diameter of the limiting portion 2713 is slightly smaller than the outer diameter of the needle body 272. The cutting portion 2711 and the expansion portion are conical, and the normal of the cutting portion 2711 forms an angle of 20-26 degrees with the axis of the hair extraction punching needle 27, and the normal of the expansion portion forms an angle of 2-4 degrees with the axis of the hair extraction punching needle 27.

[0059] When in use, the cutting portion 2711 can quickly break the scalp, and the expansion portion 2712 can expand the opening in a smaller opening state to facilitate hair removal. The outer diameter of the limiting portion 2713 is slightly smaller than the needle body 272, and a platform is formed at the connection, which can limit the insertion depth of the hair removal punching needle 27 to avoid damage to the scalp caused by inserting too deep.

[0060] When in use, a hair removal punching needle 27 with a larger inner diameter can be used for hair removal, and a hair removal punching needle 27 with a smaller inner diameter can be used for punching. Through the above scheme, the degree of damage to the scalp can be reduced. Since the hole diameter of the punching hole is smaller than the hole diameter of the hair removal hole, the hole will wrap the hair follicle more tightly after the hair transplantation, so that the hair follicle is easier to obtain nutrients and the hair is easier to survive.

The push switch is used to send a pressure adjustment signal of the first sealed cavity 321, and the adjustment signal includes a connection or disconnection signal; after the control device 51 receives the connection signal, it controls the three-way solenoid valve 45 to connect the first communication vessel 311 with the negative pressure system, so that the first sealed cavity 321 is in a negative pressure state. After the control device 51 receives the disconnection signal, the first sealed cavity 321 is connected to the air through the three-way solenoid valve 45.

[0066] The control device 51 is electrically connected to the control panel 11, and the control panel 11 is used to display hair transplantation information, including information on the number of transplanted hairs.
