A rotary electric surgical hammer impact tool has been granted a patent (Publication Number: US11925359B2) with a unique design that includes a tool body, a motor, a shaft connected to the motor, and a disk hammer element with a radial impact projection. The tool holder element features a C-shaped structure with forward and rearward impact faces that allow for axial movement within the tool body to deliver forward and rearward impacts when pressed against a work surface. The rotational direction of the shaft can be changed to switch between delivering forward and rearward impacts, enhancing the versatility of the tool.

Additionally, the patented rotary electric surgical hammer impact tool includes features such as bearings supporting the tool holder element shaft, a sensor to detect impacts, and a controller to reverse the rotation of the motor. The tool also incorporates control electronics and a battery within the tool body, a handle extending perpendicular to the body, and a microphone for voice command activation. The tool's impact force can be adjusted based on bone quality estimates and tool displacement, making it a versatile and adaptive tool for preparing bones for prosthetic devices. The method of controlling the tool involves setting an initial impact force level based on bone quality estimates, monitoring tool advancement into the bone, and adjusting the impact force accordingly. The bone quality score is determined by detecting the movement of a broaching tool within the bone, with different levels indicating varying bone quality for precise and effective surgical procedures.
