Zusammenfassung: | The utility model relates to a nail guiding device used for nail drilling for repositioning fracture of neck of the femur, which is a rectangular rigid nail guiding plate composed by the longitudinal connection of an upper and a lower two parts. The upper plate body is provided with through holes penetrated two lateral sides; the central line of the through hole has a longitudinal included angle with the lateral side of the nail guiding plate of 45-60 DEG and a projection included angle with the lateral side of the nail guiding plate of 74-82 DEG. The lower plate body is provided with a plurality of two columns of longitudinally arranged mutually symmetric through holes penetrated two lateral sides; the central line of the through hole has a longitudinal included angle with the lateral side of the nail guiding plate of 24-36 DEG and a projection included angle with the lateral side of the nail guiding plate of 74-82 DEG. One lateral side of the nail guiding plate is provided with three sharp nails; the middle is provided with a longitudinally penetrated groove. The upper end of the upper plate body is provided with an arc face corresponding to the femoral bone tuberosity part; the angle and direction of nail drilling for repositioning fracture of neck of the femur can obtain reliable precise grasp; the technique effect is greatly improved, which is favorable for the repositioning and healing for fracture site. |
