Description

A anaesthetic mask for going up alimentary canal endoscopic surgery

Technical Field

The utility model belongs to the technical field of scope operation, concretely relates to an anaesthetic mask for going up alimentary canal scope operation.

Background

The upper gastrointestinal endoscopy or operation is also called gastroscopy or operation, is a medical technology for carrying out non-invasive examination or minimally invasive operation on the upper gastrointestinal tract of a patient through a soft lens with a tubular head part provided with lighting, camera shooting and a plurality of operation channels, and is divided into 'pain' and 'no pain' according to whether anesthesia is carried out or not, wherein the pain is carried out under general anesthesia; the traditional painless gastroscope has no way to use a mask for a patient (a general anaesthetic mask has no passage through which the gastroscope passes), and as respiration inhibition is easily caused and hypoxemia is caused under general anesthesia, the examination or operation can only be stopped once the respiration inhibition or hypoxemia occurs, after the gastroscope is drawn out, the patient is buckled with the mask to carry out positive pressure ventilation and inhale oxygen, and after the blood oxygen saturation is recovered to a normal level, the gastroscope examination or operation is recovered; in recent years, there are several types of endoscope masks designed and manufactured by other companies, and the passages through which an endoscope passes can be roughly divided into three types according to different structures of the endoscope passages:

the first is direct open-hole type, the surface of the face mask is directly opened with a hole and is provided with a rubber cover, the rubber cover is opened for the endoscope to pass through during endoscope examination or operation, once hypoxemia occurs, the operation is stopped to pull out the mirror, and then the hole is buckled by the rubber cover, so that positive pressure ventilation is carried out after a sealed environment is formed in the face mask;

the second type is a rubber film type, a rubber film with a fixed hole in the middle is added at the inlet of an endoscope channel, the diameter of the hole in the middle of the rubber film is smaller than that of a conventional endoscope, when the endoscope passes through the rubber film, the film hole can be tightly hooped on the endoscope body, inspection or operation and ventilation can be ensured to be carried out simultaneously, the rubber film type endoscope has the defect that the passing of endoscopes in various specifications cannot be met, particularly, air leakage can occur when a superfine endoscope passes through the rubber film type endoscope, the resistance is large when a mirror with a thick point passes through the rubber film, the push-pull and swing-pull actions of the endoscope operation cannot be met, the operation action range of the endoscope is too large, when the elasticity limit of the film of the endoscope is exceeded, air leakage can be caused, the rubber film type endoscope can not meet patients with various facial appearances, and the endoscope channel cannot aim at the mouths of the patients at times;

thirdly, an inflatable rubber ring is added on an endoscope opening hole of the mask, after the endoscope enters, the sealing ring is inflated, the sealing ring wraps the endoscope, so that a sealing space is formed in the mask, the mirror can be normally operated, and even if hypoxemia occurs in the operation, positive pressure ventilation can be performed on a patient under the condition of not stopping the operation; the disadvantages are three, first: the radial compensation of the inflatable sealing ring is poor, and the pulling and rolling of the mirror during operation can cause the untight sealing between the inflatable sealing ring and the endoscope body and air leakage; secondly, the opening position of an endoscope channel of the mask is fixed, and the difference between the facial form and the fat and thin of a patient is large, so that the situation that the mask is not aligned with the mouth of the patient through a hole of a mirror after being fastened often occurs, and the mirror is blocked or even cannot enter the mirror; thirdly, the side surface of the mask is in a step arc shape, so that an endoscope operator cannot observe the depth of the endoscope entering the human body well in the operation.
