    摘要： A biomechanical system for testing a coupled joint is provided. The coupled joint has a fixed first end and a moving second end within the testing system. The testing system includes a servo actuation system operatively connected to the moving end. The system is able to impart at least four degrees of freedom to the moving end of the coupled joint. The testing system also includes a first force sensor disposed between the servo actuation system and the moving end of the coupled joint for sensing applied load, and a second force sensor disposed at the fixed end of the coupled joint for sensing transmitted load. The system also includes a controller for selectively directing input signals to the servo actuation system in order to apply selected forces and/or motions to the moving end of the coupled joint. The coupled joint may be a cervical spine specimen.

    摘要： A training model for endoscopic investigation and the treatment of hollow organs. The training model includes a chamber intended for accommodating the hollow organ with a chamber wall, at least one inlet fastened in the chamber wall with a coupling device to which the hollow organ can be coupled for the introduction of an endoscope through the inlet into the hollow organ, a connection in the chamber wall to which can be coupled a suction pump for the generation of a negative pressure in the chamber and a moulding in the chamber comprising a cavity into which the coupling device opens out and which is adapted to an outer contour of the hollow organ and into which the hollow organ can be inserted. The generation of a negative pressure allows the hollow organ to be widened in accordance with natural conditions.

    摘要： Disclosed herein are synthetic anatomical models that are designed to enable simulated use testing by medical device compam'es, medical device designers, individual inventors, or any other entity interested in the performance of medical devices. These models are unique in possessing a level of complexity that allows them to be substituted for either a live animal, an animal cadaver, or a human cadaver in the testing of these devices. These models are further characterized by a similarity of geometry, individual component physical properties, and component-to-component interfacial properties with the appropriate target tissue and anatomy.
