Protótipo ergonômico de dispositivo articulado para uso em ressonância magnética : método e experimento.

Abstract

The present dissertation shows the study and development of an articulated device for use in patients undergoing magnetic resonance imaging examination (RM) of lower limb, in this specific case the knee. The unit has the function to serve as a base of support and through mechanical stimuli from the device doctor can observe if the ligaments of the knee are broken. The device works through Pistons whose function move the leg that will be supported under the appliance, this does drive towards flexion-extension and rotation. The drive will be manual, i.e. it is possible to see a doctor dose the intensity of movement, is expected to contribute to the improvement in the diagnosis of knee injuries through the use of this device at the same time the visualization of images generated during the MRI examination. The development of this project is based on the literature review of the areas covered in this study and later in the project tools from methodologies such as Palh and Beitz Professor (2005), Baxter (1998) and Back (2008), which contributed to the planning and construction of the device. At the end of the study will be designed a conceptual prototype by conducting an experiment will permit an analysis regarding the usability of the device and results about the benefits and improvements brought during the evaluation of knee ligament ruptures. Expected to contribute to the advancement in the diagnosis of these injuries, allowing the patients submitted to MRI a better clinical measurement and possible surgical process guard.
