Abstract

The present disclosure relates to force sensors and force sensor substrates for use with surgical devices.

Description

Technical field [0001] The present disclosure generally relates to surgical devices. More specifically, the present disclosure relates to force sensors for powered surgical devices. Background technique [0002] Force sensors are well known, and there are multiple methods of manufacturing these types of sensors. In one approach, the sensor utilizes an adhesive strain gauge attached to a flexible substrate in the load path. For example, a simply supported steel beam used integrally with the load path may have strain gauges mounted on the beam. The strain gauge is incorporated in the Wheatstone bridge circuit configuration and includes the excitation voltage. The circuit is designed to be in equilibrium (ie, no load) before deflection, and the circuit will have resistance under zero load. During the load process, the beam will deflect and the strain gauge will produce a resistance change. This resistance change can be converted into a signal of the force value applied to the b...
