Resumo
Introdução: A alopécia androgenética está entre as dez queixas mais frequentes em cirurgia plástica e dermatologia. A única solução definitiva para alopécia androgenética é a cirurgia de restauração capilar; que se popularizou nos últimos anos com o método de extração de unidades foliculares e o desenvolvimento de tecnologia motorizada auxiliar para sua realização. As opções de aparelhos motorizados são muitas, porém, todas importadas e de alto custo. Objetivo: Desenvolver um aparelho motorizado para extração de unidades foliculares. Métodos: Foi realizada uma busca de anterioridade em bancos de dados nacional (INPI/BR) e internacionais (EPO, USPTO, Espacenet, WIPO, Google Patent Search e JPO). Para o desenvolvimento do aparelho, foi utilizada a metodologia Design Thinking, a qual divide-se em quatro fases: Descobrir, Definir, Desenvolver e Entregar. Na fase “Descobrir”, foram feitas entrevistas e pesquisa desk; na fase “Definir”, foram determinados as principais funcionalidades do aparelho; na fase “Desenvolver”, foram feitas sessões de brainstorming; e na fase “Entregar”, foram feitos o desenho industrial, protótipos e versão final do aparelho. Resultados: Foram encontradas 8 patentes na busca de anterioridade. A partir das entrevistas e pesquisa desk da fase “descobrir”, foram definidas as funcionalidades e características do aparelho. As principais são: “fácil higienização”, “console com tela touchscreen”, “movimentos de oscilação/rotação” e “acoplagem simultânea de dois handpieces”. Protótipos foram desenvolvidos e aperfeiçoados. O modelo final apresenta todas as funcionalidades definidas através do Design Thinking. Conclusão: Foi desenvolvido o Fast Graft, um aparelho motorizado para extração de unidades foliculares.
Introduction: Androgenetic alopecia is among the ten most frequent complaints in plastic surgery and dermatology. The only final solution for the androgenetic alopecia is hair restoration surgery. The popularity of the follicular unit extraction technique has been associated with the development of motorized instruments as an aid to surgery. There are many options of motorized instruments; but all have to be imported and are expensive. Objective: To develop a motorized device for follicular unit extraction. Methods: A novelty search was conducted in national (INPI/BR) and international (EPO, USPTO, Espacenet, WIPO, Google Patent Search and JPO) databases. The Design Thinking methodology, which is divided in four phases (Discover, Define, Develop, and Deliver), was used in this project. In the Discover phase, interviews and desk research were conducted; in the Define phase, the main parameters and purpose of the device were determined; in the Develop phase, brainstorming sessions were carried out; and, in the Deliver phase, the industrial design was created. Results: 8 patents were found in the search. The developed model was presented to three hair transplant surgeons, and modified until accepted by all of them. The device has a console with touchscreen to facilitate operation, oscillatory and rotational movements, and allows the coupling of two independent handpieces. The handpiece has a posterior output port to the vacuum source, ergonomic design, allows the attachment of different types of punch, and has a control pedal. The final model features all the functionality defined through Design Thinking. Conclusion: The Fast Graft, a motorized device for extraction of follicular units, was developed.
