Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and more specifically to a scalp expansion auxiliary device for hair follicle extraction. Background Art
[0002] Hair transplantation is the most effective option for repairing baldness in the medical field. It has become the mainstream hair follicle extraction method in China and the world. It requires the scalp to be expanded to make it easier to extract hair follicles. It is mainly used to assist doctors or professionals in hair follicle extraction surgery.
[0003] During the operation, the scalp is usually tightened and fixed by the hands of an assistant to increase the stability of the scalp and reduce surgical damage. However, the assistance of an assistant will not only increase the labor cost, but the hair transplant operation is time-consuming and can easily cause hand fatigue. The long-term assistance of the assistant will also increase fatigue and cause insufficient expansion of the scalp in the transplanted area, thus affecting the effect of the operation.
[0004] After searching, a Chinese patent with publication number CN109875694A discloses a scalp expansion and fixing device for hair follicle extraction. By squeezing the pressing block, a rivet needle is inserted into the hair follicle transplant area, and the scalp in the hair follicle transplant area is expanded outward by utilizing the resilience of the elastic member to maintain a certain tension and be fixed. The structure is simple and easy to operate. Since the two ends of the adjustment rod are respectively provided with a left external thread and a right external thread in opposite directions, the pressing blocks on both sides can be simultaneously driven to move outward to expand the scalp in the hair follicle transplant area by rotating the adjustment rod. The tension of the scalp can be easily adjusted to the ideal degree for the operation to avoid discomfort to the transplantee due to excessive scalp expansion, thereby improving the efficiency and success rate of the operation.
[0005] However, in actual use, the structure is fixed by inserting a rivet pin into the hair follicle transplantation area and utilizing the resilience of the elastic member to expand the scalp in the hair follicle transplantation area outward to maintain a certain tension. However, after use, the rivet pin can only be cleaned directly on the surface of the pressing block, which makes it difficult to clean the dead corner where the rivet pin contacts the pressing block, which makes it easy to breed bacteria and cause cross infection, thus affecting the use effect.
