Description

Novel multifunctional calibration instrument Technical Field The utility model belongs to the technical field of medical instruments, and particularly relates to a novel multifunctional calibration instrument. Background Long bone fractures refer to fractures that occur in human long bones, such as the femur, tibia, humerus, radius, ulna, and the like. These fractures are often caused by falls, traffic accidents, physical activity or direct impact, etc. Long bone fractures not only affect the structure and function of the bone, but also may affect surrounding muscles, nerves and blood vessels, so timely and appropriate treatment is important. When in long bone surgery, a guiding device and various screw taps are needed, the screw taps are used for pre-punching before surgery to ensure that various instruments are needed to be placed, the guiding device is used for guiding the placement paths of the various instruments, and the existing guiding device can only independently guide and mark the screw tap drill or the placement instruments. Therefore, a device capable of calibrating tap drills and insertion instruments with different specifications is designed, and the device is a novel multifunctional calibration instrument. Disclosure of utility model In order to overcome the problems in the background art, the utility model adopts the following technical scheme: A novel multifunctional calibration instrument comprises a first plate, a second plate, a first plate, a second plate and a third plate, wherein a plurality of through holes are formed in the first plate in a penetrating mode, the inner diameters of the adjacent through holes are different, a plurality of taper holes are formed in the second plate, the number of the taper holes is the same as that of the through holes, the central axes of the taper holes are in one-to-one correspondence coincidence with the central axes of the through holes, the different specifications of insertion instruments can be adapted to extend into the through holes with different inner diameters, and the insertion instruments can enter the taper holes and abut against the inner walls of the taper holes after penetrating through the through holes along the central axis continuous movement of the through holes.
