Description
Technical Field
The invention relates to medical equipment and a preparation method thereof, in particular to medical equipment for congenital esophageal locking and a preparation method thereof.
Background
Esophageal locking is a serious congenital disease of newborns, and the incidence rate is about 1/2500-1/4000 of newborns. The esophagus of the child is not continuous in nature, and the proximal end and the distal end are discontinuous and pass through to form an upper end and a lower end. The treatment of esophageal locking at the blind end has greatly advanced with the development of medical technology, but the treatment of esophageal locking at the long end still faces a plurality of problems, especially, the treatment of esophageal locking at the long end is still a difficult problem of pediatric surgery. At present, although various operation modes exist for long-section esophagus locking, most of the operation modes adopt an operation method of esophagus replacement (gastroesophageal replacement operation and colonography replacement operation), multiple operations are needed, the physiological structure is damaged greatly, and the future life quality of the sick children is seriously influenced; prolonged esophageal traction (Foker) requires repeated operations, and has long period, large wound and unsatisfactory curative effect.
There are currently two solutions to the long-segment missing esophageal lock. 1. The operation modes of the esophagus extension comprise 1) a myometrium annular incision (Livaditis operation) of the esophagus (the esophagus can be effectively prolonged by 5-10 mm), and the disadvantages are that the extension length is limited and the proximal end of the esophagus is necrotized to cause the risk of anastomotic fistula; 2) The esophagus traction (Foker) adopts external force such as suture to pull so as to accelerate the growth of esophagus, and delay the first phase anastomosis, which has the defect that the suture is easy to fall off and repeated chest opening operation is needed. 2. Esophageal replacement surgery (including gastroesophageal replacement surgery, colonography replacement surgery, small intestine replacement surgery, etc.), gastrostomy and neck esophageal proximal ostomy are performed in stage I operation, and the operation is performed after the operation by feeding through a gastrostomy tube for more than 6 months to stage II operation. The defect is that the treatment period is long, the physiological anatomical structure of the digestive tract of the infant is changed, the postoperative complications are more, and the long-term life quality is affected.
Chinese patent 105380686a discloses a device for promoting growth of the upper blind end of congenital esophageal closure, but the patent still has the following problems: 1) Only the growth promotion of the upper blind end is realized, but the accurate butt joint of the upper blind end and the lower blind end cannot be realized, and finally the upper blind end and the lower blind end still need to be sewn through an open chest operation; 2) The esophagus extension mode is comparatively rough and mechanical, and complications of esophagus extension or other unknown factors are easily caused; 3) In practical use, the feeding problem of the child patient is not considered, and the child patient still needs to take measures to feed by adopting an additional feeding pipe or other methods; 4) The problem of digestive juice accumulated in the esophagus can not be treated.

The main point of the invention is that the application adopts an experimental white rabbit (from animal experiment center in Guangdong province, third generation pure-breed white rabbit) with similar weight (1.8 kg) and similar esophagus and lumen (3 mm diameter) and muscle strength to that of a newborn, and the application finds that after the esophagus is subjected to in vitro tensile test, the esophagus is prolonged by 2mm every 9 newton force is added, and when the force exceeds 20 newton force, the esophagus is torn. After the esophagus is cut into two sections, the esophagus is sewed (similar to the upper blind end and the lower blind end of the esophagus), a magnet slightly smaller than the diameter of the esophagus is placed, after attraction test is carried out, the attraction is found to be very small when the magnet gathers outside 2cm, the attraction is insufficient to act as external force to pull the esophagus, when the attraction is increased to a distance of 1 cm, the esophagus is instantly attracted and close to and clung to the esophagus, and the esophagus is cut due to overlarge attraction. And then, magnetic force testing equipment is adopted to measure the attraction force between two magnets with the diameters of 3mm, and when the distance between the two magnets is larger than 2cm, the attraction force is negligible.
However, the common esophageal defect of the newborn is 3-7cm, and when the esophageal defect is smaller than 3cm, the esophagus can be directly forcedly sutured through operation without adopting other equipment to promote the growth of the newborn. Because the thoracic and laparoscopic surgery is minimally invasive surgery, the upper blind end conduction magnet and the lower blind end conduction magnet are adopted alone, so that self-healing penetration between the esophagus is realized, and the clinical practicability is not very high.
And this application has improved magnetic force and has acted on and increase the gravity effect through setting up porous metal ball for last blind end guiding device has the effect of promoting the growth of upper dead end of esophagus, has increased the magnetic force effect that upper dead end switched on between magnet and the lower dead end switched on magnet simultaneously, makes it can be on the esophagus and can be close to each other through magnetic force effect when the lower dead end is at the longer distance, has realized promoting the effect of esophagus growth through magnetic force. The utility model also leads to the hard tube through setting up the upper segment and leads to the hard tube and the lower segment, effectively controls the interact force between the magnet, has avoided the abrupt increase of gravitation between the magnet, leads to the condition of esophagus tearing. The application also enables the lower blind end to grow simultaneously by arranging the hydraulic propulsion device. The wound part is small, the nutrition mouth is provided for effectively supplying nutrition, and the infant can keep a certain range of activities during the operation and keep taking enough nutrition.
The method realizes accurate control of the traction force and direction of the esophageal extension, and simultaneously adopts the modes of food stimulation, proper gravity traction, magnetic traction, hydraulic thrust and gentle mechanical extension to extend the esophagus, so that the extension mode of rough machinery is avoided, complications and uncertain factors of the esophageal extension are reduced, and the method has great clinical significance.
