Abstract
We developed a medical hydraulic linear actuator for surgical assistant robotic systems. This actuator is driven by hydraulic pressure, and is disposable, and can be sterilized. It mainly consists of a polycarbonate cylinder with a diameter of 10mm and the initial length of 235mm, which elongates to the final length of 360mm. The actuator has the capability of generating forces over 2kgf and its weight is approximately 30g. We will apply this actuator to a laparoscope manipulator using parallel mechanism.
