Publication number: 20260021579Abstract: A force transmission system as part of a surgical system which may be configured to be a minimally invasive and/or computer assisted surgical system. Operation of the system may be controlled by transmission of a force from a first section to a second section of the system. The first section and the second section may be separated by a partition or a barrier. The first section may be a non-sterile section and the second section may be a sterile section of the surgical system.Type: ApplicationFiled: July 10, 2025Publication date: January 22, 2026Inventors: Christopher C.
