Description

Auxiliary device for positioning of cricopharyngeal muscle by ultrasonic Technical Field The invention relates to the technical field of medical equipment, in particular to an auxiliary device for positioning of cricopharyngeal muscles by ultrasound. Background The achalasia of the cricopharyngeal muscle is a disease which is caused by dysphagia due to the fact that the cricopharyngeal muscle of the upper esophageal segment can not be effectively relaxed and opened in the swallowing process, and water and food can not smoothly enter the esophagus, and is mainly caused by nervous system diseases such as cerebral apoplexy, cerebral hemorrhage, brain tumor and the like. Clinically, patients suffer from dysphagia, malnutrition, aspiration pneumonia, salivation, anxiety depression and the like due to incomplete or incomplete pharyngeal muscle relaxation, and if the patients cannot be effectively treated, the patients need to rely on nasal feeding tubes for eating for a long time, so that the life quality and psychological health of the patients are seriously affected. Aiming at the achalasia of the cricopharyngeal muscles, the method is commonly used for rehabilitation training, esophageal saccule dilation, cricopharyngeal myotomy and other treatment methods at present. Among them, rehabilitation training has poor curative effect, and the myotomy of the annular pharynx is difficult to be accepted by patients, and complications such as perforation of esophagus, hemorrhage, nerve injury and the like often exist. The esophageal balloon dilation is a relatively effective treatment method in clinic at present, and patients can gradually recover the opening of the cricopharyngeal muscle after a period of esophageal balloon dilation treatment, but a part of patients cannot tolerate the esophageal balloon dilation in clinic, and strong nausea and vomiting are easy to cause in the esophageal balloon dilation process, and meanwhile, the curative effect of the esophageal balloon dilation of another part of patients is not ideal. The injection of the botulinum toxin is a very mature treatment method for treating the limb muscle spasm, the botulinum toxin can inhibit the release of the presynaptic membrane acetylcholine, the target muscle relaxation is achieved, and the botulinum toxin has definite curative effect. The cricopharyngeal muscle belongs to the upper esophageal sphincter, the position is deeper, the muscle is thinner, and the accurate positioning is difficult to adopt a blind typing mode. The ultrasound can be positioned to the esophagus, but is difficult to be positioned to the cricopharyngeal muscle, the latest method at present is to use the saccule to combine with the ultrasound positioning, a nurse pulls the saccule to firstly find the most tense and most pressure position of the esophagus, namely the cricopharyngeal muscle, and then the saccule is clearly displayed by advancing ultrasound to position the cricopharyngeal muscle. However, the currently used locating balloon for the cricopharyngeal muscle is still the same as the esophageal balloon in terms of dilation, namely a common catheter commonly used in clinic. The balloon has the following problems that 1, the balloon is easy to slip, because the balloon is not easy to fix, the esophageal mucosa is smooth, the balloon is less in water injection, the cricopharyngeal muscle cannot be found, the balloon is easy to slip after the balloon is more injected, 2, the balloon is not accurate, whether the balloon is used for positioning the cricopharyngeal muscle clinically at present or depends on the hand feeling of nurses or doctors, the tension degree of the balloon in the esophagus depends on the pulling degree of individuals, the positioning method can deviate and be inaccurate due to the different experience and hand feeling of medical staff, 3, the balloon is easy to break, the cricopharyngeal muscle is thin, the muscle of the cricopharyngeal muscle is thinner after the water injection balloon supports the muscle, and the balloon can be punctured by a little force when the cricopharyngeal muscle toxin injection is carried out, so that the positioning fails. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the auxiliary device for positioning the cricopharyngeal muscle by ultrasound, which has the advantages of difficult slipping, convenient positioning and the like, and solves the problems that the balloon is easy to slip and inaccurate in positioning when the cricopharyngeal muscle is positioned by the catheter. The technical scheme is that the device comprises a handheld handle, wherein the rear end of the handheld handle is connected with a butt joint hose, the tail end of the butt joint hose is detachably provided with a disposable hose, three groups of cylindrical liquid bags are arranged at the tail of the disposable hose, three liquid injection channels are arranged in the handheld handle, the butt joint hose
