Full-featured circular cutting electric hair follicle transplantation pen

Abstract

A full-function ring-cutting electric hair follicle transplanting pen comprises a pen head and a tubular pen tip.A motor is mounted in the pen head, the pen tip is driven by the motor to rotate, the tubular pen tip is circumferentially provided with 2-4 rectangular windows uniformly, a window bottom edge of each rectangular window inclines from the outside above to the inside below, an annular sliding sleeve sleeves outside the tubular pen tip in a manner of being capable of sliding up and down, 2-4 claw-shaped blades are integrally connected below the annular sliding sleeve, the bottom edge of each blade forms a sharp cutting edge, each blade correspondingly extends into the corresponding rectangular window, and a vertical pushing mechanism pushing the annular sliding sleeve to move vertically and a vertical positioning mechanism for locating a vertical position of the annular sliding sleeve are further arranged.By using the full-function ring-cutting electric hair follicle transplanting pen, all operation steps from electric hair extracting from a supplying area to electric hair planting from a receiving area can be completed smoothly, and the number of hair of a patient can be multiplied.

Description

technical field [0001] The invention belongs to the technical field of medical cosmetic devices, and in particular relates to a full-function circular cutting electric hair follicle transplantation pen. Background technique [0002] With the increasing pressure of modern life and work, more and more men are facing the problem of hair loss, which brings heavy psychological and physical burdens to the patients. The most effective treatment method at present is hair transplantation, that is, hair transplantation in other parts (referred to as hair transplantation). The hair from the donor area) is transplanted to the hair loss site (referred to as the recipient area). [0003] The structure of the traditional electric hair follicle transplantation pen is as follows: figure 1 As shown, it includes a nib 10 and a tubular nib 1, the nib 1 is in a standard cylindrical shape, and the nib 1 is driven by a motor inside the pen cavity to rotate at high speed. The method of hair trans...

Problems solved by technology

[0005] 1. Due to the use of electric hair follicle transplantation pen and tweezers to extract hair, only the hair follicles (hair papilla) of the donor can be uprooted, and the hair follicles at the donor site will be permanently lost. During the hair transplantation process, the total number of hair follicles of the patient has not been obtained. increase, so this traditional technique has the disadvantage of "removing the east wall to make up the west wall", which not only affects the visual effect of the donor area, but also has a certain proportion of hair in the donor area, so the amount of hair available for transplantation in the donor area is limited. limit;

[0006] 2. The traditional electric hair follicle transplantation pen can only separate the hair follicle tissue. After the hair follicles are separated from the donor area, the hair follicles cannot be directly transferred to the recipient area by the electric hair follicle transplantation pen. Go to the receiving area to drill holes and plant hairs, then if image 3 As shown in , during the drilling process, the hair follicles in the lumen of the pen tip will be severely squeezed by the original tissue in the recipient area (upward extrusion, such as image 3 The hair follicles and dermal papilla in the lumen cannot stand or maintain a normal shape in the recipient area, that is, it is impossible to survive in the recipient area; therefore, the traditional hair follicle transplantation pen cannot directly transfer the hair after the donor area To transplant hair to the recipient area, it is necessary to use tweezers to transfer the hair follicles from the lumen of the electric hair follicle transplantation pen to the syringe needle (loading), but because the hair itself is very small and soft, the lumen opened by the syringe needle for hair insertion is also very small , so the loading process is time-consuming and laborious, and it is easy to damage the structure of the dermal papilla and hair follicle stem cells, resulting in a low survival rate of transplanted hair follicles in the recipient area;

[0007] 3. Only manual methods can be used to punch holes in the receiving area, and electric methods cannot be used, which may easily cause operator fatigue;

[0008] 4. The operator needs to change the instruments in his hand many times (electric pen→tweezers→syringe), the operation steps are cumbersome and time-consuming
