Abstract
An adapter assembly is provided and includes a tubular housing having a proximal end portion and a distal end portion and defining a longitudinal axis; a load sensing assembly disposed within the tubular housing in contact between a proximal surface and a distal surface, the proximal and distal surfaces perpendicular to the longitudinal axis, the load sensing assembly configured to measure a load exerted on the tubular housing, the load sensing assembly including a sensor body; and a gimbal disposed between a sensor body surface and at least one of the proximal surface or the distal surface, the gimbal configured to isolate the sensor body from the load exerted in a plane perpendicular to the longitudinal axis.
