Material testing machine for biomechanics

13年来，维尔茨堡大学医院的创伤外科诊所和综合诊所的创伤、手、整形和重建外科的生物力学研究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。为此，在人或动物的骨骼上以及人工骨骼上模拟骨折，然后使用不同的技术进行固定。然后对测试样本进行生物力学应力测试。试验在满足必要要求的材料试验机中进行，例如用于固定试件的大型试验室和用于大范围力范围的力传感器。该机器模拟与作用于人体相应区域的力相对应的压力、拉力和扭转力。除了测试骨骼外，还可以分析肌腱或软骨等其他组织在缝合或粘合缺损处后的稳定性。在维尔茨堡大学我们的诊所进行生物力学研究的过去13年里，总共出现了25种以上的出版物，并与其他研究小组进行了各种合作，其中测试是在材料试验机中进行的。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的独特卖点和较高的力限制。由于机器的老化，再也不可能进行维修了。备件不再可用。不再可能进行维护和校准。为了确保继续进行目前的研究项目，作为这项申请的一部分，要求更换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.
