Surgical electric tool, method for operating same and actuation components for same

摘要

The assembly (14) has a force sensor e.g. strain gauge, for sensing actuation force, and a switch transferred between switching states by actuation force. The switch is arranged upstream to the force sensor in direction of force transmission. A signal processing circuit influences operation of a surgical power tool (10) based on the switching states. The circuit is configured to disable the operation in one switching state independent of an actuation force value sensed by the force sensor and/or to enable the operation in the other switching state based on the actuation force value. Independent claims are also included for the following: (1) a surgical power tool comprising an actuation assembly (2) a method for actuation-force-dependent control of operation of a surgical power tool.
