Patent ID: 10849551

Abstract:
The current invention relates to an integrated device suitable for measuring the difference between a strain in a ligament at a first point in time and said strain at a second point in time, said integrated device comprising: a ligament-attaching element adapted to be fastened on said ligament; a slider module adapted to be fastened on said ligament near said first ligament-attaching element, said slider module comprising a slider guiding channel; a slider comprising a distal slider end and a proximal slider end, said distal slider end fastened on said ligament-attaching element, said proximal slider end guided in said slider guiding channel; a sensor configured to measure a strain-indicating parameter representing a position of said proximal slider end for obtaining said difference between said strain in said ligament at said first point in time and said strain at said second point in time, wherein said sensor comprises a Hall sensor which converts a position of said proximal slider end into a conditioned electrical signal carrying said measurement of said strain-indicating parameter.
