Problems solved by technology

Cases in this situation are usually treated by lengthening and suturing the upper and lower sections, but in this case, there are also situations where the distance between the upper and lower sections is too long to be directly drawn together for surgery, such as type I esophagus. Atresia, type II esophageal atresia, type III(A) esophageal atresia
In this case, the esophagus-stomach connection can be reconstructed by small bowel and colo...

Abstract

The invention relates to the technical field of medical instruments, and discloses an esophagus closing device which comprises an upper extending head, a lower extending head, a sleeve, a pull rope, a fistulization seat and a pull rope adjusting unit, the sleeve is installed between the lower extending head and the pull rope adjusting unit, and the pull rope adjusting unit comprises a base, a rotary knob and a take-up column; the base is connected with the fistulization seat, the knob is arranged on the base, the take-up column is arranged in the knob in a rotating mode, the upper end of the sleeve is connected with the base, the lower end of the sleeve is connected with the lower extending head, the pull rope penetrates through the sleeve, the upper end of the pull rope is fixedly connected with the take-up column, and the lower end of the pull rope is fixedly connected with the upper extending head. The upper extension head and the lower extension head are respectively provided with an upper involution inclined surface and a lower involution inclined surface, and when the upper extension head and the lower extension head are jointed, the upper involution inclined surface is matched with the lower involution inclined surface. Growth of the esophageal blind end of the esophageal atresia is accelerated, and meanwhile the sectional area and the perimeter of the joint of the esophagus are increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an esophagus closing device. Background technique [0002] Esophageal atresia (atresia of oesophagus) and esophagotracheal fistula (tracheoesophageal fistula) are not uncommon in the neonatal period. According to domestic statistics, the incidence rate is 1 in 2000-4500 newborns, which is similar to the incidence in foreign countries (2500-3000). 1 in 1 newborn), accounting for the third place in the developmental malformation of the digestive tract, second only to anorectal malformation and Hirschsprung's disease, and the incidence of boys is slightly higher than that of 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 gradually improved. [0003] In cases of esophageal atresia, the upper and lower segments of the esophagus are ...
