to fend off, to stab
攮 centers on forceful hand actions: pushing something away to fend it off, or thrusting a sharp object to stab.
攮 combines 扌 (hand) with 囊, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a hand action related to the meaning.
The hand radical 扌 beside the complex 囊 (which resembles a bag or container) suggests a hand forcefully pushing into or against something: fending off or stabbing.
For ドウ, imagine using a hand to fend off a charging dough-like creature: dough -> ドウ, and your hand pushes it away.
