Kurzfassung

The use of surgical tourniquet cuffs may cause complications. The rate of serious complications, however, such as muscle edema, paralyses, nerve contusions or skin lesions is < 3%.
The aim of our research project is to develop an even more patient-friendly tourniquet cuff.

The aim of our research project is to develop an even more patient-friendly tourniquet cuff. The design will be based primarily on the results of the finite element method (FEM) simulation, which describes the pressure transfer on the thigh and the interior soft tissue areas impacted by this pressure. The virtual human models developed by our consortium partner, i.e. the Institut für Materialwissenschaft (Institute of Materials Science) of the Fachhochschule (University of Applied Sciences) in Frankfurt allows us to simulate and minimize the tension in deeper layers of the body. The project comprises the development of a detailed 3D finite element model specially designed for the thigh. The model will be based on material parameters obtained through in vivo and in vitro techniques as well as test results from medical imaging techniques (MRT). These findings shall be used to optimize the shape, size, and material used for the new cuffs and to generate optimized prototypes. The goal is to noticeably reduce undesirable side effects, such as nerve contusions and skin lesions, through the application of optimized cuffs.
This pilot study is a consortium project of the Department of Orthopedics and Traumatology of the University of Mainz, the University of Applied Sciences in Frankfurt and the company Ulrich medical.
