This invention belongs to the field of medical robotic arm technology, and more particularly to a needle-holding robotic arm for minimally invasive surgery, comprising a handle, a protective shell, and a crank shell. The invention features an anti-tipping wheel located inside the crank shell near the shaft. The rim of this anti-tipping wheel presses firmly against the surface of the wire rope, effectively preventing the wire rope from slipping out of the groove in the reel during high-speed or large-angle transmission.
