Laparoscopy & robotics: a historical parallel [PDF]
Revista do Colégio Brasileiro de Cirurgiões, 2020 ABSTRACT The evolution of robotic platforms has brought up ethical, economic, educational, and clinical applicability issues that refer to the early 1990s, when laparoscopy began its dissemination as a technology that would revolutionize surgery. Introduced in Brazil since 1990, laparoscopy has received a lot of resistance from different sectors ...
