Abstract: Disclosed herein are rotary electric surgical hammer impact tools and methods of use thereof. The rotary electric surgical hammer impact tools can include a too body, a motor located within the tool body, a shaft operatively couple to the motor, a disk hammer element, and a tool holder element. The disk hammer element can be connected to the shaft and include a radial impact projection. The tool holder element can include a shaft configured to support an implement at one end and a C-shaped structure straddling the disk hammer element. Axial movement within the tool body can cause the radial impact projection to impart impacts to the tool holder element.

Abstract: Disclosed herein are linear electric surgical hammer impact tools and methods of use thereof. The linear electric surgical hammer impact tools can include a housing, a slider, a shuttle, and a motor. The housing can define a cavity extending along a longitudinal axis of the housing. The slider can be located inside the cavity and arranged along the longitudinal axis of the housing. The shuttle can be located inside the cavity and arranged along the longitudinal axis of the housing. The shuttle can include a first set of collars and a second set of collars. The motor can be configured to drive the slider along the longitudinal axis in a first direction and a second direction. Motion of the slider in the first and second directions can cause the slider to contact the first and second sets of collars.
