ARTICULATING LAPAROSCOPIC SURGICAL INSTRUMENTS

WIPO Patent Application WO/2012/058213

A3

An articulating laparoscopic instrument including a handle body, a shaft, an end effector, an operation mechanism, and an articulation mechanism. The end effector is connected to a shaft end. The operation mechanism includes a rod and an actuator. The rod is coupled to the end effector. Movement of the actuator relative to the handle body transfers a force onto the rod in a longitudinal direction to operate the end effector. The articulation mechanism includes a deflection assembly, first and second collar assemblies, first and second cables, a linkage, and an articulation actuator. The first and second collar assemblies are slidably disposed over the rod. The cables extend between the collar assemblies and the deflection assembly. Movement of the articulation actuator drives the first and second collar assemblies in opposite directions to cause a longitudinal deflection in the deflection assembly.
