Sponsor's original buckle transducer device for tendon tension
Buckle transducer in use with tendon threaded through and loaded in instron device to apply known loads
CAD Model of initial G-machine Proof of Concept Prototype
Actual G-machine Proof of Concept Prototype in use. Screws are hung to apply uniform mass to tendon laced through device. Tick marks on side frame (right) and yellow tape allow for CSA measurements.
Calibration of Hall Effect sensor using magnet, sensor and calipers to find relationship between Sensor Output and gap distance (i.e spacing between magnet and sensor). Magnet is tapped to top jaw and Hall Effect Sensor is attached to bottom jaw of calipers.
Tendon being loaded into Instron tensile loading device to applied known loads. Acrylic square is used to load various tendon samples in the same manner each time
Final G-machine Prototype in use on suspended tendon. Weight is suspended from tendon in order to place tendon in tension representing the tension a surgeon would commonly place upon one in a tendon transfer surgery
Final G-machine Prototype in use and measuring the CSA of a given tendon
