Force applicator including indicator
First Claim
1. A device for indicating the force applied by a tool to an object, comprising:
- a bar constituting a part of said tool so as to be deflected in accordance with the force applied thereby to the object;
a pair of spaced stops carried by the bar;
a frame enclosing both stops with one end of the frame engaging one side of one stop and the opposite end of the frame extending past the other stop to define a space between said other stop and said opposite end of the frame; and
a load-sensing member disposed in said latter space, whereby the deflection of said bar is converted by the two stops and the frame to a compressive force on the load-sensing member.

Abstract
A device for indicating the force applied by a tool comprises a bar arranged so as to be deflected in accordance with the force applied, a pair of spaced stops carried by the bar, a frame enclosing both stops with one end of the frame engaging one side of one stop and the opposite end of the frame extending past the other stop to define a space therebetween, and a load sensing member disposed in the latter space, whereby the deflection of the bar is converted by the two stops and the frame to a compressive force on the load-sensing member. The described load-sensing member is a photoelastic member and the described device in which it is used is a surgical spreader hand tool wherein the photoelastic member indicates to the surgeon the force applied.
