Please give more details of new technical application area:
Hip joint simulator plays the most important role in pre-clinical validation of newly developed materials. One of the most widely used and successful hip simulators is the orbital bearing machine (OBM) having the longest history of use in hip simulation and has now been manufactured or replicated by multiple research groups. Total hip replacement (THR) is one of the most successful orthopaedic surgeries in the last decade. Though THR was initially intended for osteoarthritic patients who crossed their middle age, its successful operative history made it popular to the younger generation suffering from hip injuries due to accidents or sports activities, as observed in recent trends. Hip joint simulator plays the most important role in pre-clinical validation of newly developed materials. Currently used simulators basically differ in parameters like number of station, loading cycle, ball-cup relative position, degree of freedom, lubricant chamber etc. In-vitro simulator testing of THA is a complex task because of lack of understanding of the basic wear mechanism under a variety of operating conditions. Extrapolation of short-term testing results to long term projections is still an immense challenge to the researchers. This requires a carefully design parametric study to examine the influence of speed loading cycle and motion direction on material properties and wear mechanism. Since 2000, the International Organizations for Standardization (ISO) developed guidelines for the purpose and a wide variety of hip joint simulators were developed for pre-clinical testing of newly developed Acetabular cups. The present invention is a modular mechanism, which can also be attached to a Pin-On-Disc tribometer to modify it into a orbital bearing machine (OBM) hip simulator. This device would be capable of testing prosthetic hip joints as per ISO 14242-3 with simplicity in operation.

Type of technology development: Indigenous
Does the technology help in replacing any import items currently
procured from outside India?
Yes
Does the technology have export potential? Yes
Category of Technology developed: Immediate Deployment
Stage of Development: Prototype Level
Please describe in detail including the TRL Level:
The simulator is operating successfully after its development. Initial calibration and trial runs of the device are in process using in-house developed THA. Standard commercial samples are yet to be tested in the simulator for validation and verification. The technology would be ready for large scale production and commercialization in 2021.

    Abstract:

Applications: One of the most widely used and successful hip simulators is the orbital bearing machine (OBM) conceived and designed by McKellop and Clarke. This test method differs from that in ISO 14242-1 in the articulating motion of the test. Three key features of this orbital simulator are multidirectional motion, physiological loading, and serum lubrication. Anyone of the components of a ball and socket hip replacement, i.e. any one of femoral head, ball, acetabular cup or socket is mounted on a baseplate and allowed to interface with the remaining components that is mounted vertically above. Although the OBM is not the only possible configuration among all modern hip simulator designs, and the motion of the OBM described in ISO 14242-3 is simpler and less anatomic than that in ISO 14242-1, it has the longest history of use in hip simulation and has now been popular to many reasearch group for its smplicity and realistic outcomes.
Advantages: Novelty in design of an OBM hip joint wear simulator Cost effective solution for testing THA Simplicity in design and operation A single motor to generate desired bi-axial angular motion and load generation Capable of generating in-vitro kinematics of THA as per ISO 14242-3 A load profile similar to the recommended one by ISO 14242-3 Can be integrated with a pin-on-disc machine Integrable bio-lubricant chamber Online measurement of operating temperature Online measurement of wear rate Frequency of operation can be measured and controlled

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work
read more >>

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
