Abstract
A medical instrument assembly and robotic medical system are provided. The assembly comprises a shaft, a tool carried by the distal end of the shaft for performing a medical procedure on a patient, a controllably bendable section associated with shaft and disposed proximal to the tool, an actuation element extending within the shaft and along the bendable section for controlling actuation of the tool, another actuation element configured for actuating the bendable section, and means for decoupling motion at the bendable sections from the tool actuation. The system comprises the assembly, a user interface configured for generating commands, a drive unit coupled to the actuating element and the other actuating element, and an electric controller configured, in response to the commands, for directing the drive unit to move the actuating elements to actuate the tool and drive the other actuating element to bend the bendable section.
