Minimally invasive surgical instrument

This surgical tool helps doctors perform delicate operations inside the body. It works by having the surgeon manipulate a handle that contains a spinning gyro wheel and rotating drums. This precise control is transferred via wires to a flexible tip, allowing it to bend up-down and side-to-side. The patent specifically describes a control unit with a gyro wheel and drums, and a tip with alternating pitch and yaw joints.

Why it matters: Advanced micro-manufacturing techniques have made the intricate mechanical components, like the gyro and precision joints, more feasible and cost-effective to produce than in 2011.
