Surgical screwdriver with multi-axis rotating shafts
The patent US12042197B2 describes a surgical screwdriver designed to enhance the efficiency and maneuverability of surgical procedures. The screwdriver features two rotating shafts: a first shaft that rotates about a longitudinal axis and a second shaft that extends along a development axis, equipped with a shaped end tip for engaging screw heads. A unique transmission member, consisting of two hemispherical elements hinged together, facilitates the transfer of rotational motion from the first shaft to the second. This design allows for a three-axis joint, enabling the shafts to pivot relative to one another, which is crucial for precise surgical applications.
Further details of the invention include the construction of the hemispherical elements, which are designed to slide along arched guides on the respective shafts, ensuring smooth movement. The first hemispherical element features a semi-cylindrical portion that fits into a cavity of the second element, allowing for mutual rotation. The screwdriver is encased in a cylindrical sleeve that houses the shafts and transmission member, with openings for the shafts that are not coaxial, enhancing the tool's ergonomic design. The patent outlines various configurations and features that contribute to the screwdriver's functionality, including projections for improved handling and the ability to accommodate both manual and automatic rotation actuators.
