Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically to a hair follicle extraction needle with reduced trauma. Background Art

[0002] The hair follicle extraction needle connects the handle to the hair follicle extraction head, and then the needle is inserted into the scalp in the direction of hair follicle growth to extract the hair follicles one by one. In order to reduce damage to the skin, a hair follicle extraction needle that reduces trauma is needed.

[0003] After searching, a Chinese patent with publication number CN214712622U discloses a device for extracting hair follicles without a trace. The advantage of this structure is that when the hair follicles need to be extracted, when the hair follicles enter the inside of the needle tube, the toothed disc is rotated to pull the pull rod upward, and the needle tube generates an upward attraction through the pulling of the pull rod, so that the hair follicles stay on it, which is very convenient. When the needle tube needs to be replaced, the threaded rod on the fixed block is rotated to facilitate the replacement of the needle tube. The needle of the needle tube is inclined, and when the needle enters the epidermis, the insertion area is reduced, thereby achieving a traceless extraction of the hair follicles.

[0004] However, in actual use, since the needle tube is mounted on one end of the hair follicle extraction device body through a fixing block and the needle tube has a fixed length, it is not convenient to adjust the distance between the needle tube and the hair follicle extraction device body due to the different depths of hair follicles at different positions, which not only increases the difficulty of extraction for doctors, but also causes discomfort to patients.
