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.

维尔茨堡大学医院的创伤、手、整形和重建外科诊所和综合诊所的创伤外科生物力学研究13年来一直专注于与骨折稳定和愈合相关的生物力学稳定性的临床研究。在人体或动物骨骼以及人造骨骼上模拟骨折，然后使用不同的技术稳定测试样本，然后在材料测试机中进行测试。满足必要的要求，例如用于固定测试样本的大型测试室和大力范围的力传感器。该机器模拟与作用在人体相应区域的力相对应的压力、拉伸和扭转力。除了测试骨骼之外，还可以分析肌腱或软骨等其他组织在缝合或粘合缺损后的稳定性。在过去 13 年的生物力学研究中，我们在大学诊所进行了研究。维尔茨堡总共发表了超过25篇出版物，并出现了与其他研究小组的各种合作，其中测试是在材料试验机上进行的，该机器具有大试验室和高力的独特卖点。与维尔茨堡大学校园内的其他机器相比，由于机器老化，无法再进行维修和校准。确保继续在当前的研究项目中，作为本申请的一部分，要求更换采购具有同等性能特征的材料试验机。
