Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical equipment, especially relates to a adjustable minimally invasive apical elevator. BACKGROUND

[0002] In the field of medical devices, especially in minimally invasive surgery, the apical elevator is an important tool commonly used for tooth extraction. The main function of the apical elevator is to remove the broken tooth root during tooth extraction. It can be wedged between the remaining tooth root and the alveolar bone to loosen and remove the tooth root. The apical elevator is mainly composed of a beak, a shaft and a handle.

[0003] The traditional apical elevator usually has a single fixed size and angle limitation, which is not conducive to the extraction of tooth roots. Especially in the current minimally invasive tooth extraction technology, which is widely used in the extraction of mandibular impacted teeth, the teeth are often extracted in multiple crowns and roots, and the use of apical elevator is essential. The position and depth of the broken root vary, which requires the doctor to prepare multiple apical elevators of different sizes during the treatment process, increasing the complexity of the operation and the replacement time of the instruments.

[0004] Most of the apical elevators on the market have a single design, which cannot flexibly adjust the type, size and angle of the apical elevator. Moreover, the replacement operation of the apical elevator is complicated and difficult to adjust quickly during the treatment process, especially when different types, sizes and angles of the apical elevator are needed for fine operation, which brings great inconvenience to the doctor. In addition, most of the existing apical elevators cannot effectively solve the problem of convenient storage and replacement of the beak and shaft. The doctor often needs to temporarily adjust the position of the instrument or switch to a different size of the apical elevator during the treatment process, which leads to an unsmooth treatment process and affects the work efficiency and patient experience.

[0005] Therefore, it is of great clinical application value to design a minimally invasive apical elevator that can quickly adjust the size and angle of the apical elevator to improve the operation convenience and simplify the replacement process of the apical elevator. This device not only effectively reduces the time waste caused by replacing the apical elevator, but also improves the operation efficiency of the doctor and enhances the patient's treatment experience.
