AMTI Multi-Axis Wear-Testing Machines

The simulation of human joint motion, for the purpose of testing and evaluating prosthetic devices prior to clinical use, is essential to assure the successful outcome of such surgical procedures. AMTI’s multi-axis wear-testing simulator machines provide the ideal environment for in-vitro wear, fatigue, and usability testing on a wide range of prosthetic joint components.

The Multi-Axis Wear-Testing Machine can be used as a simulator solution and for research.

AMTI’s Simulator Products - the Latest Innovative Developments

Activities of daily living: Increased forces and ranges of motion simulating a more real-life test, such as walking up and down stairs, getting out of a bath, bending over to pick up an object, running, and even swinging a golf club.

Virtual Soft Tissue control (VST): This software model is for the replication of in vivo kinetics and kinematics during movement using revolutionary technology (US Patent #7823460). VST eliminates the need for mechanical springs by using an advanced software model to incorporate the constraining influence of the soft tissue that surrounds the joint. This allows for the inclusion of nonlinear and asymmetric force displacement characteristics which occur in vivo but cannot be recreated with conventional methods. The VST control system opens up a number of exciting new research opportunities in simulation and kinematic study of TKR performance. Soft tissue modelling can be used to create a variety of surgical conditions such as cruciate sacrificing and cruciate sparing procedures. You can also investigate the effects of alignment, mal-alignment and ligament balance.

Adaptive Control Technology (ACT): This is a breakthrough in simulator ease of use and dramatic reduction in tuning time from days to minutes. The ACT control system is enabled by the press of a button and within 30 or 40 cycles of motion, the RMS error is reduced to a level not obtainable with manual tuning.

Improved tracking performance: in both force and displacement control modes of operation confirming to ISO and ASTM standards.

Microseparation: to stimulate laxity in the constraining tissue of the hip during the swing phase of gait.

The Range Of AMTI Multi-Axis Wear-Testing Machines Include:

VIVO Six D.O.F Joint Simulator
Enables more realistic biomechanics research and implant life testing. The VIVO provides accurate robotic joint motion simulation of daily activities for knee, hip, shoulder, temporomandibular, elbow, ankle and spinal joint motions.

We also supply a range of knee and hip station simulators and an ortho-pod 6 station pin-on-plate wear-testing machine.

ADL-Force 5
AMTI’s single station joint simulator has recently been updated with unparalleled testing. Up to 12 different physiological motions can be sequenced to define a particular lifestyle. Orthopaedic implants can therefore be accurately evaluated under conditions that truly replicate those experienced in everyday movement. The design also allows the machine to be used as a load frame for bending, tension and compression tests.
