Abstract
A medical device includes a mechanical structure and a force sensor unit. The force sensor unit comprises a mounting bracket, a first rod, a second rod, a first magnet, a second magnet, a first coil coupled to the mounting bracket, and a second coil coupled to the mounting bracket. The first rod and the second rod each have a center axis defined between a proximal and distal portion of the respective first and second rods. The center axis of the second rod is noncoaxial with the center axis of the first rod. The first magnet is coupled to the first rod and translates within the first coil along the center axis of the first rod. Similarly, the second magnet is coupled to the second rod and translates within the second coil along the center axis of the second rod.
