Description

Technical Field

[0001] The utility model relates to the technical field of hair transplantation needles, in particular to a multi-aperture implantation needle specially used for fine hair transplantation. Background Art

[0002] Hair transplant needles are tools used to achieve single hair transplantation during hair transplant surgery. During hair transplant surgery, doctors use hair transplant needles to extract single hair follicles (i.e. healthy hair units) from the donor area and precisely implant them into the recipient area to achieve natural and dense hair regeneration effects.

[0003] The existing technology has the following deficiencies: hair transplant surgery requires the cooperation of multiple hair transplant doctors and filling doctors. While the hair transplant doctors continuously use the hair transplant needles to transplant hair on the patient's head, the filling doctors continuously fill the empty implant needles with hair follicle units. Therefore, in a hair transplant surgery, a large number of hair transplant needles will be recycled. The aperture size of the needle tube of the traditional hair transplant needle is fixed. Because the diameters of the hair follicles required for different hair transplant areas on the patient's head are different, the traditional hair transplant needle cannot adjust the aperture size of the needle tube, resulting in the problem that it cannot adapt to the filling and implantation of hair follicles of multiple sizes.

[0004] Therefore, it is necessary to invent a multi-aperture implant needle specifically for fine hair transplantation. Utility Model Content

[0005] To this end, the utility model provides a multi-aperture implantation needle specially used for fine hair transplantation, which sleeves a first needle tube, a second needle tube and a third needle tube with different apertures together, and adjusts the aperture of the implantation needle by sliding the second needle tube and the third needle tube out of the first needle tube and into the handle, so as to solve the problem that the traditional hair transplantation implantation needle cannot adjust the aperture size of the needle tube, resulting in the inability to adapt to the filling and implantation of hair follicles of multiple sizes.
