The invention relates to an adjustable limit safety drilling device for the orthopedic department and belongs to the technical field of medical equipment for orthopedic surgery. The adjustable limit safety drilling device is used for controlling drilling depth. According to the technical scheme, the adjustable limit safety drilling device is characterized in that an opening is formed in the lateral wall of a sleeve along the length direction of the sleeve, scale marks are arranged at the edge of the opening, a marker line is arranged on the thread at the front portion of a drill rod, a limit module sleeves the drill rod, the inner-hole thread of the limit module is matched with the thread of the drill rod, a slide module is arranged above the limit module, the slide module sleeves the drill rod, the upper end of the limit module and the lower end of the slide module are provided with insertion tooth structures which can be meshed with each other, and the slide module and the drill rod are provided with a locking structure in the circumferential direction. The adjustable limit safety drilling device has the advantages that the sleeve can protect near soft tissue and guarantees that the drilling direction is accurate; the reserved safety distance for penetrating opposite cortex can be basically determined by the marker line and the scale marks; the drilling depth can be controlled effectively by the insertion connection of the limit module and the slide module; the device is simple in structure, convenient to adjust and capable of saving surgery time.
