The flexible continuum joint comprises a double-helix structure formed by two helical springs, wherein a central channel is provided inside the double-helix structure, a hollow tube arranged coaxially with the double-helix structure is provided in the central channel, and a plurality of notches are formed on the hollow tube. The flexible robotic arm is composed of a linkage joint formed by an active section and a passive section, and an end joint, wherein the active section and the end joint are both driven by a drive wire, and the passive section is driven by a nickel-titanium alloy rod. The minimally invasive surgical robot comprises an endoscopic arm and two robotic arms, and has 19 degrees of freedom overall. In addition, the provision of the linkage joint in the flexible robotic arm and the application of a hybrid drive mode combining a drive wire and a nickel-titanium alloy rod not only reduces the number of drives, but also avoids the problem of motion coupling between joints, thus effectively overcoming the problems of insufficient degrees of freedom and poor motion accuracy in existing minimally invasive surgical robots for TEM.
