Abstract
Embodiments of a robotic medical system comprise a steerable instrument that includes a bendable body and a connector assembly configured to detachably connect the bendable body to an actuation unit. A controller is configured to control the actuation unit. The connector assembly comprises a connection receptor coupled to the actuation unit and a connecting shaft coupled to the bendable body. The connecting shaft includes a plurality of driving rods that are attached in a one-to-one correspondence to a plurality of driving wires and that detachably attach to the connection receptor. In a connected state where the bendable body is connected to the actuation unit via the connector assembly, the controller causes the actuation unit to transmit an actuating force from an actuator to a driving rod, and the driving rod actuates or moves a driving wire in a same direction as the actuating force applied by the actuator.
