Surgical Manipulators TRIZ Cases

A planar electromagnet array with curved core tips boosts magnetic force in tight C-arm imaging spaces while preserving robot control precision.

Planar electromagnet rows with curved core tips increase magnetic field strength while fitting around C-arm imaging paths.

Offset openings, a cavity, and channels secure the cable end and body to reduce slippage and improve robotic end effector positioning.

A friction-based locking unit bridges moving body parts to lock at any position and uses elastic release to cut complexity and free play.

A switchable planetary differential keeps surgical instrument cables tensioned across operating states, reducing slack and assembly complexity.

Closed-loop feedback adjusts surgical stapler motor speed from velocity error and stall conditions to keep firing motion precise during tissue cutting.

A friction-based locking unit wedges between moving members to stop relative motion, reduce free play, and allow selective release.

Captured operator motion patterns let a robot replay situation-specific instrument movements, improving precision and easing complex minimally invasive navigation.

A movable locking unit wedges between two body parts to stop relative motion by friction, while an unlocking unit releases the lock cleanly.

A wedged locking unit creates friction between movable body parts to hold any position, then releases when an unlocking unit pushes it.
