Abstract
A force detection bone screw device includes a bone screw body, a spring structure, a detection module, and an antenna module. The bone screw body includes a cylinder. The spring structure, the detection module and the antenna module are respectively arranged in the accommodation portion of the column. The spring structure includes a body, a bearing part, a fixing part and at least one bending strain structure. One end of the body is connected to the bearing part, and the other end of the body is connected to the fixing part, and the fixing part is fixed in the cylinder. Each bending strain structure is respectively provided on the body. The body has an axial direction, and each bending strain structure has deformation in at least one direction different from the axial direction. The detection module includes at least one strain element and a sensing component.
