A surgical power tool has an actuation assembly for the actuation-force-dependent control of the tool. The actuation assembly includes a force sensor configured to sense the actuation force and a carrier component for the force sensor which is arranged upstream of the force sensor in a direction of force application and is coupled thereto in a force-transmitting manner. A mechanical damping member is arranged upstream of the carrier component in the direction of force application. The damping member protects the carrier component and the force sensor, for example, from impacts and shocks and the accompanying plastic deformations.

Surgical power tool and actuation assembly therefor

A sterilizable surgical power tool and an operating unit for the surgical power tool are described. The operating unit includes a hermetically sealed metal capsule for arrangement in the region of a housing of the surgical power tool, the capsule having a contact surface for a finger on an outer face. A force sensor which is in force-transmitting connection to the contact surface is arranged inside the capsule. At least one electrical contact leads out of the capsule. The capsule may be a low-cost standard transistor housing.

Surgical electrical tool, activation unit and calibration method therefor

A surgical power tool has an actuation assembly which comprises a force sensor and a switch. The force sensor is provided to determine an actuation force produced by the user, and the switch is transferred by the actuation force from a first switching state to a second switching state. A combined evaluation of the force sensor signal and of the switching state enables, for example, a plausibility check for increasing the operational reliability of the power tool.
