Abstract
Surgical instruments having articulating portions or joints are described herein. In one embodiment, a surgical instrument can include a distal end effector, a proximal actuating portion, and an articulating portion disposed between the end effector and the actuating portion. The articulating portion can include an inner component formed of a first material and an outer component formed of a second material, wherein a modulus of elasticity of the first material is higher than a modulus of elasticity of the second material. Such an instrument can be less complex and less expensive than known articulation mechanisms while providing similar capabilities.
