Abstract

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

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to U.S. Provisional Patent Application No. 62 / 384,878, filed September 8, 2016, which is hereby incorporated by reference in its entirety. 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 gauges that are attached to the flexing 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. Strain gauges are incorporated in a Wheatstone Bridge Circuit configuration and include an excitation voltage. The circuit is designed to be balanced (ie, no load) before deflection, and the...
