Abstract
Recent advances in minimally invasive surgical procedures have created a demand for smaller scale tools with improved performance characteristics. Attempts to scale down modern tools to the meso level (1-5 mm) have caused severe performance losses. Surgical tools of the present invention provide significant improvements in operable range and force application for both grasping and spreading when compared to currently used endoscopic forceps. This is achieved by using two actuators that separately control the spreading and grasping functions of the surgical tool.
