摘要:
An artificial synovial fluid comprising a serum, a chelator, and a buffer is provided. In particular embodiments, the artificial synovial fluid may further comprise an antibiotic. The artificial synovial fluid is generally used in tribological testing of medical device implants such as artificial joints. Methods of using and making the artificial synovial fluid are also provided.
摘要:
A servo-controlled impacting device for orthopedic implants includes one or more sensors, an impacting device, and a controller with an interface. The controller is configured to provide control signals to an impactor in response to feedback signals from at least one sensor proximate an orthopedic implant subject to a force applied by the impactor. The interface is coupled to the controller and is configured to enable parameters to be set related to the operation of the controller.
摘要:
The invention relates to a test apparatus and a test method for the testing of samples by mechanical action upon the sample. The test apparatus comprises a sample region and a cylinder, which is movable in relation to the sample region, and at least two linear drives, each with a first drive part, which is fixed in place with respect to an end of the sample region, which faces it, and with a second drive part, which is movable in relation to the first drive part and is driven and which is fixed in place with respect to the cylinder. Advantageously, the movement axes of the linear drives run parallel to the longitudinal axis of the cylinder. In a preferred embodiment, a test set-up of the test apparatus has a rigid load frame.
