Abstract
A calibration system for a tensiometer provides a platform having a footplate with a fulcrum bar for providing a located force on an individual's leg to be used in conjunction with a tissue stress sensor attached near a tendon or ligament of the leg to establish a relationship between force on the tendon or ligament and the tissue stress sensor output for simplified calibration.
Claims15
A tissue tensiometer calibration system comprising:
- a base supportable against a horizontal surface;
- a footplate positioned above and connected to the base by one or more force sensors sensing a downward force on the force plate with respect to the base, the force sensors providing an electrical force output signal indicating a force on the footplate;
- a fulcrum bar attached to an upper surface of the footplate to provide an upwardly and laterally extending ridge to isolate a weight of an individual standing on the footplate to force on the ridge;
- and
- a support bar attached to the base to provide a handle positionable above the base at a height to be held by an individual standing on the footplate.

A method of calibrating a tissue tensiometer having:
- a base supportable against a horizontal surface;
- a footplate positioned above and connected to the base by one or more force sensors sensing a downward force on the force plate with respect to the base, the force sensors providing an electrical force output signal indicating a force on the footplate;
- a fulcrum bar attached to an upper surface of the footplate to provide an upwardly and laterally extending ridge to isolate a weight of an individual standing on the footplate to force on the ridge;
- and
- a support bar attached to the base to provide a handle positionable above the base at a height to be held by an individual standing on the footplate;
- the method comprising:
- (a) positioning an individual to stand on the footplate with varying downward force;
- (b) receiving at an electronic computer a corresponding set of output force signals and signals from the tissue tensiometer;
- and
- (c) relating the set of output signals from the tissue tensiometer to provide a calibration function calibrating the signals from the tissue tensiometer to a force-related dimension.
