 It has been almost 40 years since research began in the pursuit of robotic microsurgery. Recently, the clinical use of surgical robots created for microsurgical vessel anastomosis was launched in Europe. MUSA was the first surgical robot dedicated for microsurgery and first-in-human lymphaticovenular anastomosis was reported in 2020. The Symani Ⓡ surgical system followed MUSA and reported first-in-human free flap reconstruction in 2023. At Kyushu University, we have been working since 2013 on the development of a new domestic surgical robot specialized for microsurgery, with the support of a Japanese government grant. For the robot to perform the function of a doctorʼs hands, we are making robotic hands that achieve ultra-precise tracking accuracy of ± 0.01 mm beyond the hand of an expert surgeon. For the robot to be able to “see”, we use a 3D microscopic system with resolution comparable to a visual acuity of 4.27, which exceeds that of the naked eye. The latest prototype was completed in December, 2021, and we succeeded in suturing a 1-mm artificial vessel using this robot in 2022. We tried the first animal experiment using a rat in 2023, succeeding in suturing a rat artery 0.8 mm in diameter. We assume that the use of robotic microsurgery will spread all over the world in the near future. Our final product is nearing completion and we hope to introduce our microsurgical robot for every microsurgeon in 2024.
