Open Surgery Initiative Aims to Build DIY Surgical Robots

Medical equipments can be really expensive because of the R&D involved and resulting patents, low manufacturing volume, government regulations, and so on. Developed countries can normally afford those higher costs, but for many it may just be prohibitively expensive. The Open Surgery initiative aims to mitigate the costs by “investigating whether building DIY surgical robots, outside the scope of healthcare regulations, could plausibly provide an accessible alternative to the costly professional healthcare services worldwide”. The project is composed of member from the medical, software, hardware, and 3D printing communities, is not intended for (commercial) application, and currently serves only academic purposes. Commercial surgical robots can cost up to $2,000,000, but brings benefits like smaller incisions, reduced risks of complications and readmissions, and shorter hospital stays thanks to a faster recovery process. There have already been several attempts within the robotics community to come up with cheaper and more portable surgical […]
