Embodiment Construction

[0017] The new anchorage nail of the present invention is improved on the basis of the existing anchorage nail structure, and the universal sleeve 2 and the universal sleeve fastening screw 3 for locking the universal sleeve 2 and the anchorage nail 1 are added. . Such as figure 1 As shown, the novel anchorage nail of the present invention is composed of an anchorage nail 1 , a universal sleeve 2 and a universal sleeve locking screw 3 . The structure of anchorage nail 1 is as follows figure 2 As shown, the anchorage nail 1 includes an anchorage nail head 13, an anchorage nail neck 12 and an anchorage nail threaded part 11. A receiving tool is arranged on the anchorage nail head 13 to rotate the anchorage nail rotating tool receiving part. In this embodiment, the rotating tool receiving part of the head of the anchorage nail is a hexagonal recess 14, and the hexagonal screwdriver cooperates with the hexagonal recess 14 to rotate the anchorage nail 1 to penetrate into the imp...

Abstract

The invention discloses a novel anchorage nail, which includes an anchorage nail head, an anchorage nail neck and an anchorage nail screw thread part. A universal sleeve sleeves the anchorage nail neck side of the anchorage nail head and is radially provided with a threading hole. A universal sleeve fastening screw can fix the universal sleeve and the anchorage nail head together. The heads of the anchorage nail head and the universal sleeve fastening screw are provided with a turning tool receiving part for receiving a tool to turn the anchorage nail and the universal sleeve fastening screw. The universal sleeve is turned to make an anchorage wire to rotate through 360 degrees in a plane vertical to the axis of the anchorage nail. The anchorage wire passes through the threading hole formed in the universal sleeve, can be positioned at any direction, and is locked through the universal sleeve fastening screw, thereby achieving anchorage orthodontics. Two or more than two anchorage nails can draw the same anchorage wire, and the orthodontics is carried out through combined force, so that the anchorage nails can be implanted without being limited by the physiological structure and the stress is uniformly dispersed. The novel anchorage nail provides wide application range and better orthodontic effect for anchorage nail orthodontics.

Description

technical field [0001] The invention belongs to the field of medical devices, specifically relates to the technical field of dental orthodontic devices, in particular to a novel anchorage nail. Background technique [0002] We know that anchorage nails are simple in structure, small in size, easy to implant and remove, and do not require the use of intraoral and extraoral devices. As an anchorage, they will not cause unnecessary movement of other teeth, and are widely used in orthodontic treatment. . At present, the conventional anchorage nails used clinically include the head of the anchorage nail, the neck of the anchorage nail and the threaded part of the anchorage nail. Traction orthodontics is performed by setting the anchorage wire on the head or neck of the anchorage nail. When the anchorage nail is screwed into the patient's body, the direction of the anchorage wire cannot be adjusted flexibly. The anchorage method of the anchorage nail is single anchorage, and the ...
