AI Technical Summary

Technical Problem

Existing dental implant traction devices are difficult to accurately determine whether they have rotated to the maximum height position, and the sleeve removal process is cumbersome, increasing surgical trauma and the risk of infection.

Method used

A self-unloading dental implant traction device is designed. By setting a first internal thread and a second internal thread at intervals on the inner sleeve of the base body, and setting a first external thread and a second external thread at intervals on the outside of the connecting screw, when the connecting screw rotates to the top of the base body, the connecting screw and the inner sleeve are not threadedly connected and rotate freely, thereby achieving automatic unloading.

Benefits of technology

It enables accurate assessment of the structure of dental implant traction devices, avoiding the risk of secondary surgery and infection caused by misjudgment, and simplifies the operation process.

Abstract

本申请公开了一种自卸式牙种植牵引装置,该装置包括种植体、连接螺杆和底座体。本申请通过在所述底座体的内套筒上间隔设置第一内螺纹和第二内螺纹,在推动种植体上升的连接螺杆外侧间隔设置第一外螺纹和第二外螺纹,当所述连接螺杆旋转至所述底座体的顶部时,以使所述连接螺杆与所述内套筒之间无螺纹连接而空转,便于在使用时准确判断牙种植牵引器结构是否旋转到最大高度位置,避免误判造成的二次手术及感染的风险,在牵引到位时,同时套筒自动脱卸,无需再使用拆卸扳手进行拆卸,简化了操作流程。
