Lateral-viewing virtual endoscope system and detecting method

Abstract

The invention relates to a lateral-viewing virtual endoscope system and a detecting method. The lateral-viewing virtual endoscope system comprises a flexible body, a first movable carrier, at least one distance sensor and a processor. The distance sensor is disposed on the flexible body through the first movable carrier. Each distance sensor rotates around the axis of the flexible body under the rotating power output by the first movable carrier so as to sense the distance to the wall of a to-be-detected pharyngeal cavity. The processor is used for receiving the sensing signals fed back by the distance sensors, generating the virtual image of the to-be-detected pharyngeal cavity according to the sensing signals and acquiring the corresponding detecting result according to the virtual image, and accordingly the cross section radial lines and sectional area of the parts of the to-be-detected pharyngeal cavity and pharyngeal cavity surface contour data can be acquired, and collapse conditions of the to-be-detected pharyngeal cavity can be acquired. The lateral-viewing virtual endoscope system has the advantage that the collapse change of each plane of the to-be-detected pharyngeal cavity in each sleep stage under the sleep state of a patient can be detected continuously without medicine induction.

Description

technical field [0001] The invention relates to an endoscope technology, in particular to a side-view virtual endoscope system and a detection method for detecting pharyngeal cavity collapse. Background technique [0002] In recent years, OSAHS (Obstructive sleep apnea hypopnea syndrome) has gradually received more attention. It is a sleep-breathing disease, and its clinical manifestations include nocturnal sleep snoring with apnea and daytime sleepiness. Recurrent nocturnal hypoxemia and hypercapnia caused by apnea can lead to complications such as hypertension, coronary heart disease, diabetes, and cerebrovascular disease, and even sudden death at night; daytime sleepiness may cause traffic accidents that endanger health and even life . [0003] At present, for patients with OSAHS caused by excess soft tissue deformities (such as tonsil hypertrophy, soft palate in obese patients, tongue hypertrophy, etc.) and hard tissue deformities (such as micromandibular deformity, etc...

AI Technical Summary

Problems solved by technology

[0004] Among them, the observation angle of the laryngoscope used in awake fiberoptic laryngoscopy or sleep fiberoptic laryngoscopy is toward the depth of the pharyngeal cavity, and the accuracy of the observed pharyngeal cavity stenosis or collapse is poor, and due to sleep fiberoptic laryngoscopy Microscopic examination needs to be induced by sedative drugs for the patient, and the measurement results under normal physiological conditions of the patient cannot be obtained

During the monitoring process, sleep MRI will be disturbed by the noise of the machine itself, which will affect the test results and reduce the accuracy of the test results, which will adversely affect the patient's surgical treatment effect

However, the radiation of CT examination and sleep lateral fluoroscopy is relatively large, which will cause secondary damage to the patient's body.

The above inspection is limited to the inspection time and cannot be monitored overnight, so it cannot be used to obtain the collapse changes of the pharyngeal cavity in each sleep stage of the patient
