Embodiment Construction

[0025] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0026] Such as figure 1 , figure 2 as shown, figure 1 It is a schematic diagram of the structure of the blind end growth-promoting device for congenital esophageal atresia, figure 2 for figure 1 The left view of the upper blind end of the congenital esophageal atresia in this embodiment, including the guide tube 1 and the guard plate 2 that limits the position of the guide tube 1. In this embodiment, the guide tube should not be too soft and should have a certain force or displacement conduction capacity, specifically, it should be able to transmit the force or displacement applied at one end to the other end, and at the same time, it should not be too hard to av...

Abstract

The invention discloses a congenital oesophagus atresia upper-blind-end growth promoting device, belonging to the technical field of medical devices, and comprising a guiding catheter and a guard plate for limiting the guiding catheter, wherein the guiding catheter comprises a guiding end and an advancing end, the end part of the guiding end is provided with a protection airbag, the excircle surface of the advancing end is provided with scales along the axial direction, and a clamping fixing device is arranged between the guard plate and the advancing end. The device enters the oesophagus of a human body through the guiding catheter, stabs and pushes the upper blind end of the oesophagus, and promotes the growth of the blind end; meanwhile, an advancing quantity needed each day can be accurately controlled through the clamping fixing device and the scales, the oesophagus is promoted to grow uniformly and stably, and an expected aim is achieved; an oesophagus atresia operation method is simplified, operation wounds and operation risk are reduced, a treatment effect of oesophagus atresia operation is improved, and the life is better saved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device capable of accelerating the accelerated growth of esophagus in congenital esophageal atresia. Background technique [0002] Esophageal atresia (atresiaofoesophagus) and esophageal tracheal fistula (tracheoesophagealfistula) are not uncommon in the neonatal period. According to domestic statistics, the incidence rate is 1 case in 2000-4500 newborns, which is similar to the foreign incidence rate (2500-3000 newborns). 1 case among children). It accounts for the third place in the developmental malformations of the digestive tract, second only to anorectal malformations and Hirschsprung's disease. Boys have a slightly higher incidence than girls. In the past, most children with this disease died within a few days after birth. In recent years, due to the development of pediatric surgery, the success rate of surgical treatment has been improving day by d...
