Esophageal electrode intubation training method based on mixed reality and system thereof

Abstract

The invention relates to an esophageal electrode intubation training method based on mixed reality and a system thereof. The method comprises the following steps: building a body esophagus model, initializing the position of a virtual esophagus electrode and calibrating the standard intubation track of the virtual esophagus electrode; adjusting the actual position of the virtual esophagus electrode in the body esophagus model according to operation sensing information generated by a trainer, and determining feedback friction force of the trainer according to the actual position; and displayingdeviation information between the actual position and the standard intubation track so as to guide training personnel to adjust the intubation operation. By building the body esophagus model, adjusting the actual position of the virtual esophagus electrode in the body esophagus model according to the operation signal generated by the trainer receiving esophagus electrode intubation operation of training personnel, and simultaneously determining the feedback friction of the trainer according to the actual position, the method and the system of the invention are convenient for the training personnel to perform visual perception and tactile sensation of the intubation process, and are good for the training personnel to timely adjust the intubation operation, rapidly grasp the intubation skill and improve the learning efficiency.

Description

technical field [0001] The invention relates to the technical field of mixed reality, in particular to a mixed reality-based esophageal electrode intubation training method and system. Background technique [0002] Body surface electrocardiogram is the gold standard for diagnosing arrhythmia, and it has provided timely, accurate and reliable diagnostic basis for clinical diagnosis and treatment for one hundred years. However, some arrhythmias can only be described when the patient attacks, and the recording point is limited to the body surface, resulting in unclear P waves, so the specific origin of the arrhythmia or the sequence of cardiac activation cannot be clarified, and it is difficult to correct for some complex arrhythmias diagnosis. [0003] Both the esophagus and the heart are located in the mediastinum, with the heart anterior and the esophagus posterior, separated only by the pericardium. The anterior wall of the lower end of the esophagus is closely adjacent t...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, medical staff acquire the skill of esophageal electrode intubation by intubating the patient’s esophagus through the mouth / nasal cavity, so for medical staff who are not skilled in intubation skills, the success rate of intubation is low, and intubation is prone to occur. Deviations such as mistakenly entering the trachea cause extreme discomfort to the patient, especially if the insertion position of the esophageal electrode cannot be accurately grasped, which will easily lead to inaccurate ECG parameters and affect the diagnosis of the patient's condition. There is no equipment for intubation training for patients' esophagus in existing technologies, which is not conducive to medical staff learning and acquiring esophageal intubation skills
