There is a gap between the inner wall of the sleeve 4 and the outer wall of the clearing needle 3, and a guide part 5 is fixedly connected to the upper edge of the end of the sleeve 4 away from the needle seat 2.
[0040] The beneficial effects of this embodiment are: the grease injection needle 1 is set to a pointed tip, which can perform scar injection more accurately compared to a conventional blunt-tip needle, reduce the number of punctures, alleviate trauma, and save operation time; and it is cleared through the needle seat 2 and the clearing needle 3 to avoid blockage of the grease injection needle 1, and is easy to use; the guide part 5 facilitates the positioning of the grease injection needle 1 before inserting it into the sleeve 4, and can more easily insert the sleeve 4.
[0041] Specifically, the fat injection needle 1 is composed of a needle tip 101, a needle stem 102 and a needle plug 103, the needle tip 101 and the needle plug 103 are respectively located at two ends of the needle stem 102, the head of a conventional fat injection needle is a blunt head, which can be used for subcutaneous fat transplantation, but for intrascar injection, the operation of the blunt needle head is difficult due to the hard texture of the scar, in the embodiment, the fat injection needle 1 is changed to a sharp head and the opening is arranged at the top end, which can better perform scar puncture;
[0042] During use, if the fat injection needle 1 is blocked, it needs to be dredged, first, the needle tip 101 is placed against the guide part 5, then one end of the needle tip 101 is pushed into the sleeve 4, the sleeve 4 is slightly larger than the outer diameter of the needle stem 102, the dredging needle 3 is slightly smaller than the inner diameter of the needle stem 102, the sleeve 4 limits the outer peripheral wall of the fat injection needle 1 to avoid shaking, and the dredging needle 3 is inserted into the fat injection needle 1 from the direction of the needle tip 101 to dredge;
[0043] The guide part 5 is slightly arc-shaped and has the same arc degree as the inner diameter of the sleeve 4, which facilitates the positioning of the fat injection needle 1 against the guide part 5 and better insertion into the sleeve 4, if there is no guide part 5, the needle tip 101 needs to be accurately inserted into the sleeve 4, which is not convenient to use and is also very easy to prick the hand.
[0044] On the basis of the embodiment, the guide part 5 can be a straight plate, an arc-shaped plate or any other shape, as long as it is higher than the top end of the sleeve 4 and has the functions of guiding and positioning.
[0045] Embodiment 2
