Anchorage nail connecting rod and digital orthodontic anchorage nail guide plate using same

Abstract

The utility model relates to the technical field of medical instruments, and provides an anchorage nail connecting rod and a digital orthodontic anchorage nail guide plate using the anchorage nail connecting rod. Comprising a connecting rod and an inserting rod, scale marks are arranged on the connecting rod, and the scale marks extend from the first end of the connecting rod to the second end of the connecting rod. The anchorage nail has the beneficial effects that the scale marks on the connecting rod of the anchorage nail extend from the first end part to the second end part, and the length of the connecting rod is greater than the height of the guide part of the guide plate; when the anchorage nail is screwed in under the action of the connecting rod, the scale marks on the connecting rod are always exposed out of the top surface of the guide part, so that the implantation depth can be accurately observed, and the tooth root and the planing structure are unlikely to be accidentally injured. Most importantly, the connecting rod is free of steps, the diameter of the connecting rod is matched with the hole diameter of the guide part, the guide part can guide the connecting rod all the time, and accurate implantation of the anchorage nail can be achieved by matching with scale marks on the connecting rod.

Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to an anchorage nail connecting rod and a digital orthodontic anchorage nail guide plate using the same. Background Art

[0002] In the prior art, the doctor inserts the anchor pin into the connecting rod of the screw driver and then implants the anchor pin into the patient's oral cavity by hand. If the implantation depth is not appropriate, it is easy to accidentally damage the tooth root and the anatomical structure.

[0003] The connecting rod of the screwdriver used for implanting the support nail is provided with a step 51 at the head of the support nail, and the step 51 is connected to the connecting rod body 52. ​​The diameter of the step 51 is larger than the diameter of the connecting rod body 52. Figure 4-5 When the step 51 passes through the guide part, the guide part will lose its guiding function, and the guide part cannot guide the connecting rod body 52 (the diameter of which is smaller than the aperture of the guide part), resulting in the guide plate having difficulty in controlling the implantation direction to achieve precise implantation, and there is no depth guide on the connecting rod. When the connecting rod head enters the guide part of the guide plate, it is difficult to judge the implantation depth.

[0004] In view of this, the present invention is proposed. Utility Model Content

[0007] In an optional embodiment, the length of the scale line is equal to or greater than 4 cm.

[0008] In an optional embodiment, the diameter of the connecting rod is larger than the diameter of the plug-in rod.

[0009] In an optional embodiment, a mounting portion is provided at the first end of the connecting rod, and an anchoring nail is installed in the mounting portion.

[0010] In an optional embodiment, a limiting portion is provided on the plug-in rod.

[0011] In an optional embodiment, the connecting rod and the plug-in rod are integrally formed.

[0012] On the other hand, the utility model also provides a digital orthodontic anchorage nail guide plate using the anchorage nail connecting rod as described above, comprising: an anchorage nail guide plate body, on which a guide portion is provided.
