Claim Text:
1. An actuation assembly for an actuation-force-dependent control of the operation of a surgical power tool, comprising: a force sensor capsule capable of being mounted in an opening of a housing of the power tool; a force sensor arranged in the force sensor capsule configured to sense the actuation force; the force sensor capsule having a metal first cover section which is arranged proximal of the force sensor in a direction of force application and is coupled thereto in a force-transmitting manner, wherein the force sensor is configured to detect a deformation of the metal first cover section and wherein the force sensor is hermetically sealed against sterilization media; a mechanical damping member which is arranged on an outer surface of the metal first cover section in the direction of force application, the mechanical damping member formed of an elastic material; a spring plate disposed between the mechanical damping member and the metal first cover section, wherein the spring plate is spaced apart from the metal first cover section in an undeflected state, and wherein application of the actuation force to the mechanical damping member deflects the spring plate toward the first cover section; and wherein the spring plate has an upper surface and a lower surface and a switching contact surface, both the upper and lower surfaces are coated with an electrically insulating material, with the switching contact surface free of the insulating material.
