Material testing machine for biomechanics

维尔茨堡大学医院的创伤、手部、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集中在与骨折稳定和愈合相关的生物力学稳定性临床研究上超过13年。为此，在人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进行稳定。然后对测试样本进行生物力学应力测试。测试在满足必要要求的材料试验机中进行，例如用于固定测试样本的大型测试室和用于大力范围的力传感器。该机器模拟与作用于人体相应区域的力相对应的压缩力、拉伸力和扭转力。除了测试骨骼，其他组织，如肌腱或软骨，也可以分析其稳定性后，修复或粘合后的缺陷。在过去13年的生物力学研究中，我们在维尔茨堡大学的诊所共发表了超过25篇论文，并与其他研究小组进行了各种合作，其中测试是在材料测试机上进行的。与维尔茨堡大学校园内的其他机器相比，该机器具有大型测试室和高力极限的独特卖点。由于机器老化，已无法进行维修。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继续，作为本申请的一部分，要求更换采购一台具有同等性能特征的材料试验机。

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.
