AI Technical Summary

Technical Problem

Existing positioning and fixation devices for fixing the patient's head cannot adapt to different physiological and anatomical dimensions. The fixation process is cumbersome and unreliable, making it difficult for patients to maintain a static posture for a long time when taking panoramic oral and maxillofacial images, which easily produces artifacts.

Method used

The ear clip positioning mechanism includes two ear clip assemblies and a clamp plate. By adjusting the axial movement and rotation of the adapter sleeve and ear clip rod, and the deflection of the clamp plate, three-degree-of-freedom positioning of the patient's head can be achieved, adapting to different physiological and anatomical sizes and improving fixation reliability and comfort.

Benefits of technology

It enables rapid clamping and fixation of the patient's head, adapts to different physiological and anatomical sizes, improves the fixation reliability and comfort during the imaging process, and avoids the generation of artifacts.

Abstract

This application relates to an ear clip positioning mechanism, an ear clip positioning device, a head positioning device, and an oral CBCT device. The ear clip positioning mechanism includes two ear clip assemblies, each comprising an ear clip rod, an adapter sleeve, and a clamp. Each ear clip rod has a first end, and the first ends of the two ear clip rods can move towards or away from each other. The adapter sleeve is connected to the first end of the ear clip rod and can move and rotate along the axial direction of the ear clip rod. The clamp is connected to the adapter sleeve and located within an accommodating space, and the clamp can deflect relative to the adapter sleeve. The ear clip positioning mechanism provided in this application allows adjustment of the clamp position in three degrees of freedom by adjusting the moving position and rotation angle of the adapter sleeve relative to the ear clip rod, and the deflection angle of the clamp relative to the adapter sleeve. This allows the clamp to be placed against the patient's head for rapid clamping and fixation, improving the reliability of the ear clip positioning mechanism for fixing the patient's head. Furthermore, adjusting the clamp can adapt to the physiological and anatomical dimensions of different patients' heads.
