Disclosed herein are bi-spring surgical impact tools and methods of use thereof. The bi-spring surgical impact tools can include a housing, a shuttle, a pinion, and first and second springs. The housing can define a cavity having a first end and a second end. The shuttle can be located within the cavity and define a plurality of indentations. The pinion can be located proximate the shuttle and have a plurality of protrusions sized to mesh with the plurality of indentations during rotation of the pinion. The first and second springs can be mechanically coupled to the housing and the shuttle. Rotation of the pinion in a first direction can translate the shuttle in a first direction towards the first end of the housing and rotation of the pinion in a second direction can translate the shuttle in a second direction towards the second end of the housing.
