A simulator for testing finger joint replacements was developed. Movement intervals of 15 degrees at flexion and extension plain can be set using an adjustable crank drive. The maximum range of motion is 105 degrees, 90 degrees being the maximum flexion and 15 degrees the extension. Thus, the simulator is also suitable for impingement tests. A constant joint load is infinitely variable from 20 N to 500 N. Test frequency is also infinitely variable from 0.2 Hz to 2 Hz. A modular assembly of the components of the prosthesis means that these can be positioned as required, and that any type of prosthesis may be tested. The design and the material allow for an all-round lubrication at a heat up to 37 degrees C. The equipment is designed for permanent operation. Pre-clinical quality assurance for finger joint replacements can be considerably improved by the implementation of the present simulator.
开发了一种用于测试手指关节置换物的模拟器。在屈伸平面上可通过可调曲柄驱动器设置15度的运动间隔。最大运动范围为105度,最大屈曲为90度,伸展为15度。因此,该模拟器也适用于撞击测试。恒定的关节负荷在20牛至500牛之间无级可变。测试频率也在0.2赫兹至2赫兹之间无级可变。假体组件的模块化组装意味着这些组件可以根据需要定位,并且可以测试任何类型的假体。该设计和材料允许在高达37摄氏度的温度下进行全方位润滑。该设备设计用于连续运行。通过使用本模拟器,可显著提高手指关节置换物的临床前质量保证。
