Abstract(s)
A laparoscopia é uma técnica cirúrgica minimamente invasiva que começou a ser desenvolvida há aproximadamente um século e devido as suas vantagens, como a rápida recuperação dos pacientes, tornou-se o foco de diversos estudos para a melhoria dos equipamentos e da técnica. Entretanto os equipamentos possuem um sério problema de ergonomia na sua configuração, o que causa diversos problemas musculosqueléticos para os cirurgiões, causando por exemplo: dores musculares, parestesia temporária, fadiga, dentre outras patologias a longo prazo. O estudo e o desenvolvimento de novos modelos de manípulo e a redução das forças necessárias para a sua manipulação é de fundamental importância no campo da laparoscopia. Dessa forma, este trabalho apresenta a integração do método de desenvolvimento de produto de Pahl e Beitz (2007), do método DSR (Design Science Research) e do DFMEA para o desenvolvimento de um instrumento laparoscópico, para ser aplicado em pinças e tesouras e que atende os requisitos ergonómicos apresentados pela literatura. Através da união dos 3 métodos foi possivel apresentar um protótipo virtual do manípulo e do sistema de transmissão, bem como alguns estudos para apresentar a sua eficácia e reduzir o risco de falhas do produto.
Laparoscopy is a minimally invasive surgery (MIS) technique that began to be developed approximately a century ago and due to its advantages, such as the rapid recovery of patients, it has become the focus of several studies for the improvement of the equipment and the technique. However, the equipment has a serious ergonomic problem in its configuration, which causes several musculoskeletal problems for surgeons causing, for example: muscle pain, temporary paresthesia, fatigue, among other long-term pathologies. The study and development of new handle models and the reduction of the forces required for their manipulation is of fundamental importance in the field of laparoscopy. In this sense, this work presents the integration of the product development method of Pahl and Beitz (2007) and the DSR (Design Science Research) method for the development of a laparoscopic instrument, to be applied in tweezers and scissors, that meets the ergonomic requirements presented in the literature. Through the union of the 3 methods it was possible to present a virtual prototype of the handle and of the transmission system, as well as develop some studies to present its effectiveness and reduce the risk of product failures.
