The biomechanical research in trauma surgery at the clinic and polyclinic for trauma, hand, plastic and reconstructive surgery at the University Hospital in Würzburg has focused on clinical research into biomechanical stability in connection with fracture stabilization and healing for over 13 years. For this purpose, fractures are simulated on human or animal bones as well as on artificial bones and then stabilized using different techniques. The test specimens are then subjected to biomechanical stress tests. The tests are carried out in a material testing machine that meets the necessary requirements such as a large test room for fixing the test specimens and force transducers for large force ranges. The machine simulates compressive, tensile and torsional forces that correspond to the forces that act on the respective region in the human body. In addition to testing bones, other tissues such as tendons or cartilage can also be analyzed for their stability after suturing or after gluing a defect. In the past 13 years of biomechanical research in our clinic at the University of Würzburg, a total of more than 25 publications have emerged and various collaborations with other research groups have emerged, in which the tests were carried out in the material testing machine. The machine has the unique selling points of the large test room and the high force limits compared to other machines on the campus of the University of Würzburg. Due to the age of the machine, it is no longer possible to carry out repairs. Spare parts are no longer available. Maintenance and calibration are no longer possible. In order to ensure the continuation of the current research projects, a replacement procurement of a material testing machine with equivalent performance characteristics is requested as part of this application.

临床诊所外手术的生物力学研究和尤尔兹堡大学医院的创伤，手，塑料和重建手术的多诊所的生物力学研究集中在与骨折稳定和愈合有关的生物力学稳定性研究上。为此，对人或动物骨骼以及人造骨骼进行了模拟裂缝，然后使用不同的技术稳定。然后对测试样品进行生物力学应力测试。测试是在满足必要要求的材料测试机中进行的，例如用于固定测试样品的大型测试室，并为大力范围固定强制传感器。机器模拟与对人体作用的力相对应的压缩，拉伸和扭转力。除了测试骨骼外，还可以分析其他组织（例如肌腱或软骨），以为其缝合后或粘合缺陷后其稳定性。在过去13年的生物力学研究中，我们在Würzburg大学的诊所进行了生物力学研究，总共出现了25多个出版物，并与其他研究小组进行了各种合作，其中在材料测试机中进行了测试。该机器具有大型测试室的独特卖点和与温尔茨堡大学校园的其他机器相比的高力极限。由于机器的年龄，不再有可能进行维修。备件不再可用。不再可能进行维护和校准。为了确保当前研究项目的延续，要求对具有同等性能特征的物质测试机进行替换，作为本应用程序的一部分。
