Posterior nostril atresia supporter

Abstract

The invention relates to the field of ophthalmology and otorhinolaryngology surgical instruments, and particularly discloses a posterior nostril atresia supporter. The posterior nostril atresia supporter comprises two developable breather pipes, the outer ends of the breather pipes are in a horn mouth shape, grooves are arranged in the two ends of each breather pipe and one side of the nasal septum respectively, drainage grooves are formed in the breather pipes, and included angles between the grooves and the drainage grooves from the cross section range are 60-120 DEG; and through holes are formed in the walls of the breather pipes. The posterior nostril atresia supporter can be selected according to the age of a child patient, does not need to be manufactured temporarily, can be put in quickly, can be changed along with deformation of the nasal cavity and the nasal passage, and is easy to replace and convenient to maintain.

Description

technical field [0001] The invention relates to the field of ENT surgery instruments, in particular to a back nostril blocking supporter. Background technique [0002] Posterior nostril atresia is a critical disease that directly threatens the life of newborns. Due to bilateral choanal atresia, the baby has difficulty breathing and lack of oxygen. Only emergency endotracheal intubation can ensure the safety of the child's life. To survive tracheal intubation, choanoplasty must be performed in the early stage, but there is currently no equipment specifically used to support the posterior nostrils, and there is no surgical instrument specifically used for choanoplasty. [0003] Clinically, when the posterior nostrils are formed, after the posterior nostrils are opened, it is necessary to prevent the posterior nostrils from being closed again.

[0002] Posterior nostril atresia is a critical disease that directly threatens the life of newborns. Due to bilateral choanal atresia, the baby has difficulty breathing and lack of oxygen. Only emergency endotracheal intubation can ensure the safety of the child's life. To survive tracheal intubation, choanoplasty must be performed in the early stage, but there is currently no equipment specifically designed to support the choanal, and there is no surgical instrument specifically designed to perform choanoplasty

[0003] Clinically, when the posterior nostrils are formed, after the posterior nostrils are opened, it is necessary to prevent the posterior nostrils from being closed again. Therefore, it is necessary to place a support for more than 6 months. Currently, the clinically used support is temporarily made during the operation. The production process It takes about 1.5-2 hours, which prolongs the operation time and increases the amount of anesthesia for children, and the materials used are not uniform. Some use tracheal intubation, some use three-way tubes, and some use chest drainage tubes.

Endotracheal intubation is relatively hard, which can compress the perforation of the nasal septum and deform the alae of the nose, adding additional complications to children; the wall of the three-way tube and chest drainage tube is thicker, and the lumen is thinner, which is easy to be blocked by nasal scabs and requires repeated cleaning of nasal endocrine The most important thing is hypoventilation, and some still have dyspnea

The common disadvantage of the three is that they are all straight, without scale marks, unknown insertion length, no groove, inconvenient fixation, and easy rotation, resulting in the inner end of the ventilation tube being blocked by nasopharyngeal tissue, unable to ventilate, and unable to follow the nasal cavity. and curved nasal passages
