3D simulation otolith resetting demonstration device

Abstract

The invention relates to a 3D simulation otolith resetting demonstration device. The 3D simulation otolith resetting demonstration device includes semi-regular tube models and a fixing belt. Each semi-regular tube model has a front semi-regular tube, a rear semi-regular tube, an outer semi-regular tube and an elliptical capsule, wherein the front semi-regular tube, the rear semi-regular tube and the outer semi-regular tube include double tube cavities; the outer tube cavities and the inner tube cavities are made of a transparent material; the outer tube cavities are filled with transparent liquid, and the inner tube cavities are filled with colored liquid; and a plurality of movable particles of simulation otolith are arranged in the inner tube cavities of the semi-regular tube model and are used for simulating otolith particles. The fixing belt is formed by connecting a horizontal circular fixing belt and a longitudinal fixing belt. The semi-regular tube models are arranged a left endand a right end of the longitudinal fixing belt respectively. The 3D simulation otolith resetting demonstration device can help doctors to see a movement track of otolith reset more intuitively, andthe doctors can quickly find out the correct resetting method without too much thinking, and adopt an accurate reset posture; the accuracy of treatment is improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a medical instrument, a medical teaching demonstration instrument, in particular to a demonstration of semicircular canal otolith reset treatment, in particular to a three-dimensional simulation otolith reset demonstration device. Background technique [0002] Vertigo is one of the common clinical diseases that seriously affect the quality of life of patients. Patients consciously feel dizzy, accompanied by severe symptoms such as nausea, vomiting, and cold sweats, and many vertigo diseases will recur without warning, making patients fearful, anxious, and even dying. Benign paroxysmal positional vertigo (BPPV) is the most common vertigo disease, accounting for more than 25% of all vertigo patients, and the number of patients is extremely large. The pathogenesis of the disease has been basically clarified: the otoliths of the inner ear otoliths fall off into different semicircular canals, resulting in short-term dizziness due t...

AI Technical Summary

Problems solved by technology

However, due to the special three-dimensional structure of the semicircular canal, in medical teaching, it is difficult for beginners to accurately understand the process of otolith reset from the description in the textbook and the schematic diagram

In clinical treatment, doctors should also adopt different otolith reset methods according to the otolith shedding enters different semicircular canals, and design the treatment reset steps. However, in the absence of physical reference, it is difficult to sort out the sequence only by relying on the doctor's mind , it is easy to cause precise confusion of steps

So far, although some inventions have provided an intuitive demonstration of otolith repositioning, it is difficult to accurately locate and simultaneously display nystagmus performance in real time, so as to guide teaching and clinical practice
