Abstract

A minimally invasive surgical instrument includes a U-turn mechanism that transmits actuating forces around a U-turn. The U-turn mechanism is coupled between segments of the instrument and has a bend radius that is smaller than flexible arms having a similar cross section diameter. The actuating forces transmitted by the U-turn mechanism are used to move distal components of the instrument, such as an end effector and a wrist mechanism.
