AMTI Force Measurement Systems products

The VIVO Joint Simulation System by AMTI revolutionizes the field of joint motion simulation by offering unparalleled kinetic and kinematic realism to approximate in-vivo conditions closely. This system is equipped with a groundbreaking full-speed, full-load environment that supports six degrees of freedom, allowing for comprehensive testing of various joint prostheses and biological specimens. Its compact design optimizes laboratory space while facilitating the study of human joints. The VIVO's capabilities are enhanced by its virtual soft tissue models, including the multi-fiber ligament and heuristic constraint models, which simulate soft tissue forces critical for accurate joint contact force recreation. The system supports dynamic test protocols, covering a spectrum from standard daily activities to extreme sports and injury scenarios. Its robust design includes a temperature-controlled serum circulation system for fluid-environment tests and utilizes advanced control systems for stability and precision in cyclic testing, making it highly suitable for ISO and ASTM standard-compliant research.

AMTI's ADL Hip Simulator is a sophisticated 12-station joint simulator designed for comprehensive testing of hip implants. It stands out for its ability to simulate a wide range of physiological motions associated with daily activities, such as running and bending. The simulator features advanced microseparation capabilities, crucial for understanding wear on prosthetic devices. Its Adaptive Control Technology ensures highly accurate tuning with minimal manual intervention. Each station is equipped with a peristaltic pump that provides a temperature-controlled fluid bath, replicating physiological conditions. The system employs servo-hydraulically generated motions with long-life, laminar seal actuators, ensuring over 108 cycles. Fully equipped for implant testing, it includes 12 integrated multi-axis load cells, enabling precise measurement of forces across three axes. The simulator is compliant with ISO and ASTM standards for hip and spine implants and offers versatility for testing other joints. AMTI also provides robust technical support through its ASAP service plan tailored to lab needs.

The ADL Knee Simulator by AMTI is a state-of-the-art testing device designed to evaluate the design and materials of knee implants with unparalleled precision. Developed for use in orthopedic implant testing, this 6-Station Knee Simulator accurately replicates the complex motions associated with daily activities, such as running or bending, which are critical for assessing the performance and longevity of knee implants. Featuring AMTI's Virtual Soft Tissue (VST) control, this simulator eliminates the need for mechanical springs and replicates in vivo force-displacement characteristics more accurately than traditional methods. The Adaptive Control Technology (ACT) optimizes the machine's tuning speed, reducing errors in force and displacement control modes to under 5%. Additional features include servo-hydraulically generated motions, readiness for ISO and ASTM standard testing, and adaptability for simulation of other joints. This simulator is equipped with a peristaltic pump for controlled fluid recirculation, ensuring that the physiological environment is consistently maintained.
