In vitro cyclic loading and load-to-failure testing of muscles and tendons require a reliable linking device between tissues and the actuator that can transmit high loads without slippage or tissue damage. This article describes a simple custom-made thermoelectrically cooled freeze clamp. The effectiveness of the clamp to transmit loads without tissue slippage was evaluated on 10 canine quadriceps femoris myo-tendinous junctions in both load-to-failure and cyclic loading settings. Dynamic cyclic loading during an extensive period of time was successfully achieved. Loads up to 4.84 kN were applied in quasi-static conditions without evidence of clamp slippage or failure.
在体外对肌肉和肌腱进行循环加载和失效测试,需要在组织和执行器之间有一种可靠的连接装置,该装置可以在不发生滑移或组织损伤的情况下传递高载荷。本文介绍了一种简单的定制热电冷却冷冻夹具。通过在失效和循环加载设置下对 10 个犬股四头肌肌-腱连接点进行测试,评估了该夹具在不发生组织滑移的情况下传递载荷的有效性。成功实现了长时间的动态循环加载。在准静态条件下施加高达 4.84 kN 的载荷,没有出现夹具滑移或失效的迹象。
