Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples. It is to be understood that the examples are illustrative of the invention only and are not limiting.

Example 1

As shown in fig. 1-2, the present embodiment provides an accurate traceless hair follicle extraction device, which includes an extraction tip 100, the extraction tip 100 includes a tip main body 120, an extraction needle tube 110 is disposed at one end of the tip main body 120, the extraction needle tube 110 has a length of 2.5-4 mm and an outer diameter of 0.7-0.72 mm.

Through the arrangement of the length and the outer diameter of the extraction end 100, the end body 120 and the extraction needle tube 110 in the embodiment, when a doctor extracts hair of a hair transplant person, the extraction needle tube 110 is 2.5-4 mm long, so that the extraction end 100 does not extend into the scalp too deeply, and capillary vessels under the scalp are prevented from being damaged by the extraction end 100; since the outer diameter of the extracting needle tube 110 is 0.7-0.72 mm and the diameter of a hair follicle is 0.2-0.6mm, the hair follicle of the scalp of a hair-transplant is preferably prevented from being excessively divided during extraction, so that the outer skin of the hair follicle needs to be separated again after extraction.

In this embodiment, the end of the tip body 120 away from the extraction needle tube 110 is provided with a connection portion 130, and the connection portion 130, the tip body 120, and the extraction needle tube 110 are coaxially disposed.

Through the arrangement of the connecting portion 130 in this embodiment, the extraction tip 100 is connected to the driving device through the connecting portion 130, thereby facilitating the installation of the extraction tip 100.

In this embodiment, a counter bore 210 is disposed on the outer side wall of the tip body 120, an arc-shaped hole 220 for communicating the counter bore 210 with the extraction needle tube 110 is disposed in the tip body 120, and the inner diameter of the counter bore 210 is greater than the inner diameter of the connection end of the arc-shaped hole 220 and the counter bore 210.

Through the arrangement of the counter bore 210 and the arc-shaped hole 220 in the embodiment, the extraction needle tube 110 can be blocked after long-term use, when the extraction needle tube 110 is blocked, a worker can insert a soft needle from the opening of the arc-shaped hole 220 and extend out from the opening of the extraction needle tube 110, so that the worker can dredge the extraction needle tube 110 conveniently; meanwhile, the arc-shaped hole 220 does not enable the other end of the extraction needle tube 110 to generate air flow to penetrate when one end of the extraction needle tube 110 is inserted into the scalp, so that blood is extracted from the scalp, and the damage to a hair user is reduced better; through the arrangement of the counter bore 210, when the needle tube 110 is cleaned and extracted, because the inner diameter of the arc-shaped hole 220 is smaller, the injection head of the injector cannot stretch into the counter bore 210, so that the injection head stretches into the counter bore 210, clean water is conveniently injected into the needle tube 110, and the inner side wall of the needle tube 110 is conveniently cleaned and extracted.

In this embodiment, the inner diameter of the arc-shaped hole 220 gradually decreases from the end connected to the counter bore 210 to the end connected to the extraction needle tube 110.

Through the setting that the internal diameter of arc hole 220 in this embodiment reduces gradually from the link with counter bore 210 to the link with drawing needle tubing 110 for the staff is when stretching into arc hole 220 with soft needle, because the internal diameter of arc hole 220 reduces gradually from the link with counter bore 210 to the link with drawing needle tubing 110, so the radian of buckling of soft needle is less, thereby the preferred soft needle of having prevented is broken.

In this embodiment, the end of the extraction needle 110 away from the tip body 120 is provided with an inner chamfer 230.

Through the arrangement of the inner chamfer 230 in the present embodiment, the end of the extraction needle tube 110 contacting with the scalp is relatively sharp, thereby facilitating the scalp to be cut by the extraction needle tube 110.

In this embodiment, the inner sidewall of the extraction needle 110 is a smooth wall 240.

Through the arrangement of the smooth wall 240 in the embodiment, the tissue in the scalp is not easy to adhere to the inner side wall of the extraction needle tube 110, so that the tissue in the scalp is preferably prevented from adhering to the inner side wall of the extraction needle tube 110, and the worker can conveniently clean the inner side wall of the extraction needle tube 110.

As shown in fig. 3-7, the tip main body 120 is further provided with a dredging mechanism for dredging and extracting the needle tube 110, the dredging mechanism includes a mounting cavity 530 disposed in the tip main body 120 and communicated with the arc-shaped hole 220, a mounting groove 410 disposed along the length direction of the tip main body 120 is disposed on the sidewall of the tip main body 120, a sliding cavity 510 communicated with the mounting groove 410 and the mounting cavity 530 is disposed between the mounting groove 410 and the mounting cavity 530, a limiting rod 420 disposed along the length direction of the mounting cavity 530 is disposed in the mounting cavity 530, a spring 430 is sleeved on the outer sidewall of the limiting rod 420, a dredging needle 520 disposed along the length direction of the mounting cavity 530 is disposed in the mounting cavity 530, a connecting rod 610 penetrating through the sliding cavity 510 and extending into the mounting groove 410 is disposed on the sidewall of the dredging needle 520, and a sliding piece 450 sleeved on the limiting rod 420 and capable of moving and squeezing the spring 430 on the limiting rod 420 is disposed at one end of the connecting rod 610 extending into the mounting groove 410.

Through installation cavity 530 in this embodiment, installation groove 410, sliding chamber 510, gag lever post 420, spring 430, dredge needle 520, the setting of connecting rod 610 and slider 450, make the staff only need promote slider 450, make slider 450 slide in installation groove 410 along gag lever post 420, slider 450 removes, thereby drive connecting rod 610 and slide in sliding chamber 510, connecting rod 610 removes, drive dredge needle 520 and remove, thereby make dredge needle 520 stretch into and draw in needle tubing 110, dredge and draw needle tubing 110, the staff loosens slider 450 at last, spring 430 can promote slider 450 and reset, thereby make dredge needle 520 and connecting rod 610 reset, thereby the preferred has made things convenient for the staff to dredge fast and draw needle tubing 110.

In this embodiment, the sliding piece 450 is provided with a first through hole 710 for the limiting rod 420 to pass through; a second through hole 720 for the connecting rod 610 to pass through is arranged on the side wall of one end of the dredging needle 520; a third through hole 440 communicating with the mounting groove 410 is formed on an end surface of the tip body 120 adjacent to the connecting portion 130.

Through the arrangement of the first through hole 710, the second through hole 720 and the third through hole 440 in the embodiment, when an installer installs the dredging needle 520, the installer firstly pushes the dredging needle 520 into the installation cavity 530 from the opening of the extraction needle tube 110, then extends one end of the connecting rod 610 into the installation groove 410 and penetrates through the sliding cavity 510 to be inserted into the second through hole 720 on the dredging needle 520, then puts the spring 430 into the installation groove 410, enables the spring 430 to be located at the lower end of the sliding piece 450 to press the sliding piece 450, and finally passes the limiting rod 420 through the third through hole 440 and the first through hole 710 on the sliding piece 450 to be extended into the installation groove 410, thereby preferably facilitating the installation of the connecting rod 610, the spring 430, the dredging needle 520, the limiting rod and the sliding piece 450.

In short, the above description is only a preferred embodiment of the present invention, and all the equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the scope of the present invention.
