US 2026/0060732 A1 · ORTHOPEDIC IMPACTOR INCLUDING A SOLENOID ARMATURE POSITION SENSING SYSTEM

Abstract

An orthopedic surgical impactor and corresponding methods of operations. The impactor includes an electromagnetic component having a stationary electromagnetic housing and a moving armature component. The stationary electromagnetic housing includes a coil configured to receive an electric current resulting in generation of an electromagnetic field for triggering translation of the armature component within the stationary electromagnetic housing. The electromagnetic field is configured force the armature component to translate in at least one direction. The impactor includes a sensing component having at least one processor. The processor is configured to determine an inductance, associated with the electromagnetic field, based on at least one of: at least one current output signal and at least one voltage output signal generated by the coil, and determine, based on the inductance, a position of the movable armature component within the stationary electromagnetic housing.
