Abstract

The present disclosure relates to force sensors and force sensor substrates for use with surgical devices. The force sensor includes a substrate, a plurality of sensing elements, a distal plate, and a pin-block assembly. The substrate includes a proximal end portion and a distal end portion, the distal end portion including a proximal end facing surface in fluid communication with the distal end surface via an opening extending therebetween. The plurality of sensing elements are mounted on a sensing region of the distal surface of the substrate. The distal plate is welded to the distal surface of the substrate to hermetically seal the plurality of sensing elements between the distal plate and the distal surface of the substrate. The pin-block assembly is welded to the proximally facing surface of the distal end portion of the substrate, thereby hermetically sealing a plurality of conductive blocks between the pin-block assembly and the substrate the far end of the pin.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of and priority to US Provisional Patent Application No. 62 / 384,878, filed September 8, 2016, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure generally relates to surgical devices. More particularly, the present disclosure relates to force sensors for powered surgical devices. Background technique [0004] Force sensors are known, and there are various methods of making these types of sensors. In one approach, the sensor utilizes bonded strain gages that are attached to the flexure substrate within 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 gages were incorporated in a Wheatstone Bridge Circuit configuration and included the excitation voltage. The circuit is designed to be in equilibrium (ie, no load) prior to ...
