Within the framework of this thesis adaptive mechanisms for laparoscopic surgery were developed to allow secure and gentle tissue grasping and joining. These mechanisms were designed considering the load properties of tissue and specific clinical functionalities. New approaches and customized development procedures were applied, with regard to medical requirements as technical constrains. The different types of graspers are based on compliant mechanisms and allow gripping tissue whether with parallel jaws to manipulate organ walls or with fingerlike jaws to catch convex surfaces. The implants for tissue joining were designed by combining several absorbable materials. These implants provide adaptation according to the thickness of organ walls. The mechanisms were validated technically as well as in a medical environment. Additionally, a novel mechanism for the placement of implants with the assistance of a flexible grasper is presented.
