BACKGROUND At present, the da Vinci surgical robot system does not provide haptic feedback. One of the authors has proposed a contact-force sensing method called the 'overcoat method', in which the instrument/driver is supported by force sensors. In the da Vinci robot, the instrument jaws are powered by a wire-pulley mechanism; thus, in order to apply the(More)
Infection with human parvovirus B19 (PVB19) induces acquired pure red cell aplasia (PRCA). Chronic hemolytic anemia is well known as an underlying condition. However, additional factors have been recognized to accompany parvoviral PRCA; however, there are only limited reports on iron-deficiency anemia (IDA) and rituximab-induced B-cell dysfunction. We(More)
For delicate operations conducted using surgical robot systems, surgeons need to receive information regarding the contact forces on the tips of surgical instruments. For the detection of this contact force, one of the authors previously proposed a new method, called the overcoat method, in which the instrument is supported by sensors positioned on the(More)
