Roll-pitch-roll surgical tool

This is a robotic surgical tool with a long shaft and a highly flexible tip. The tip uses a system of linking arms and a wrist to bend in multiple directions, including bending back beyond 90 degrees, allowing it to reach difficult areas. Cables running through the shaft control these bending motions.

Why it matters: Since 2005, advancements in miniaturization, precision manufacturing, and robotic control systems make complex, cable-driven surgical tools more feasible.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMiniaturized precision mechanics, cable actuation, control systems
