More Information
Summary:A hydraulically actuated medical instrument includes an elongated shaft having proximal and distal ends, a hydraulically actuated end effector at the distal end of the shaft and a fluid flow path extending through the shaft to the end effector. The end effector may be directly manually operated by way of a handle located at the proximal end of the shaft or remotely, for example, via robotic controller. Articulation joints may be provided along the shaft, between the shaft and end effector or handle, or elsewhere. The hydraulic actuation of the present invention permits multiple axis instrument articulation, miniaturization and simplified instrument fabrication.
