Description

Technical Field

[0001] The utility model belongs to the technical field of oral tools, and particularly relates to an oral probe type orthodontic bracket locator. Background Art

[0002] A bracket locator is an essential tool for adjusting the position of brackets on the tooth surface in orthodontic clinics. The probe type orthodontic bracket locator is a kind of locator, with hooks at both ends, combining the functions of a probe and a bracket locator. When used as an oral probe, the application method is the same as that of an ordinary probe.

[0003] However, the hooks at both ends of this probe type locator are in a fixed state and cannot be adjusted in angle during use. When the patient has irregular or crooked teeth, the hooks at both ends of the probe operated by medical staff cannot be flexibly adjusted according to the patient's tooth condition, thus affecting the positioning operation of the bracket.

[0004] Therefore, there is a need for an oral probe type orthodontic bracket locator that is easy to adjust the angle, has a simple structure, and is convenient for positioning operations. Summary of the Utility Model

One end of the first hook needle is fixed with a first collar, and the first collar is movably sleeved outside the connecting shaft. One end of the second hook needle is fixed with a second collar, and the second collar is movably sleeved outside the connecting shaft.

[0007] As a preferred technical solution of the oral probe type orthodontic bracket locator of the utility model, a moving hole runs through the middle of the grip. One end of the moving hole is located on one side of the first collar, and the other end of the moving hole is located on one side of the second collar.

[0008] As a preferred technical solution of the oral probe type orthodontic bracket locator of the utility model, moving grooves are symmetrically arranged on the outer wall of the grip. External threads are fixed on the inner wall of the moving grooves. A limiting groove is arranged on the top surface of the moving grooves, and a first positioning component is threadedly connected inside the moving grooves.

[0009] As a preferred technical solution of the oral probe type orthodontic bracket locator of the present utility model, the first positioning assembly includes an operation cylinder and a positioning rod. The operation cylinder is threadedly connected to the inner side of the moving groove. A positioning rod is provided inside the operation cylinder, and the positioning rod is located inside the moving hole.

[0010] As a preferred technical solution of the oral probe type orthodontic bracket locator of the present utility model, a sliding groove is provided in the middle of the inner wall of the operation cylinder. An internal thread is fixed to one end inner wall of the operation cylinder, and the internal thread is threadedly connected to the outside of the external thread.

[0011] As a preferred technical solution of the oral probe type orthodontic bracket locator of the present utility model, the positioning rod includes a pressing rod. The pressing rod is located inside the moving hole. One end top surface of the pressing rod is fixed with a connecting rod. The connecting rod penetrates through the limiting groove. A limiting arc plate is fixed to the top of the connecting rod. The limiting arc plate is clamped inside the sliding groove. The other end of the pressing rod is fixed with a pressing pad, and the pressing pad is located on one side of the first collar.

[0012] As a preferred technical solution of the oral probe type orthodontic bracket locator of the present utility model, a second positioning assembly is installed on the grip. The second positioning assembly is symmetrically arranged with the first positioning assembly, and one end of the second positioning assembly is located on one side of the second collar.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] When the present utility model is in use, by setting the first hook needle, the second hook needle, the first positioning assembly and the second positioning assembly, the first hook needle and the second hook needle are respectively movably sleeved at both ends of the grip, and the first positioning assembly and the second positioning assembly are installed on the grip. The first positioning assembly corresponds to the first hook needle. During use, according to the specific conditions of the teeth on the inner side of the patient's oral cavity, the first hook needle can be rotated and adjusted at the end of the grip. After adjusting to a suitable angle, the operation cylinder of the first positioning assembly can be screwed, so that the operation cylinder moves on the external thread, thereby driving the positioning rod inside the grip to move, so that the pressing pad at one end of the positioning rod can stably press on the first collar of the first hook needle, thereby realizing the pressing and fixing of the first hook needle. The second hook needle and the second positioning assembly are operated in the same way. Therefore, it is convenient for medical staff to adjust the inclination angles of the hook needles at both ends of the probe type locator according to the oral teeth conditions of the patient, so that it can better realize the positioning operation, with good positioning effect, simple structure, convenient adjustment and strong practicability.
