Patent CA-2473482-A1 (CA)
Title: A surgical instrument with a lateral-moving articulation control
Inventor: WALES KENNETH S
IPC: A61B17/28
Filed: 2004-07-09
Abstract: An articulating surgical instrument suited for endoscopic use includes a lateral articulation control into a handle portion that provides an intuitive visual and tactile indication to the clinician as to the amount and direction of articulation of an end effector at a distal end of a shaft. Lateral movement of a lateral control actuator in converted into a longitudinal motion or a rotational motion transferred by the shaft to an articulation mechanism. A version of a lateral articulation control for a rotational driven articulation mechanism incorporates an articulation backdrive lockout that prevents forces on the end effector from causing the selected amount of articulation from being changed.
