Problems solved by technology

At present, there are still many problems in the application of laparoscopic mesh in the treatment of esophageal hiatal hernia. The material and shape of the mesh still have many problems, such as the mesh corrodes the esophagus and stomach, the mesh cannot be well adapted to the esophagus, and the shape of the mesh cannot meet the defect of esophageal hiatal hernia. diverse performance

Embodiment 1

[0022] Such as figure 1 As shown, the special patch for hiatal hernia described in this embodiment includes a poly L-lactide-caprolactone (PLCL) absorbable layer 10, and a mesh poly Propylene non-absorbable layer 20; in application, the outer surface of said absorbable layer 10 is placed facing the stomach, and the outer surface of said non-absorbable layer 20 is placed facing the diaphragm. Because the polypropylene network structure is conducive to the growth of tissues, it can quickly induce the formation of scars in the surrounding tissues and achieve the effect of strengthening the edge of the esophageal hiatus. Poly L-lactide-caprolactone (PLCL) has good biocompatibility and stability, and can avoid the adhesion or formation of scar tissue between the patch and the abdominal viscera and omentum, which will affect the movement of the esophagus and cause abdominal viscera shift. The area of ​​the absorbable layer is larger than that of the non-absorbable layer, but both ...

Embodiment 2

[0024] Such as figure 2 As shown, the special patch for hiatal hernia described in this embodiment includes a poly L-lactide-caprolactone (PLCL) absorbable layer 30, and a mesh poly Propylene non-absorbable layer 40; in application, the outer surface of said absorbable layer 30 is placed facing the stomach, and the outer surface of said non-absorbable layer 40 is placed facing the diaphragm. Because the polypropylene network structure is conducive to the ingrowth of tissues, it can quickly induce the formation of scars in the surrounding tissues and achieve the effect of strengthening the edge of the esophageal hiatus. Poly L-lactide-caprolactone (PLCL) has good biocompatibility and stability, and can avoid the adhesion or formation of scar tissue between the patch and the abdominal viscera and omentum, which will affect the movement of the esophagus and cause abdominal viscera shift. The area of ​​the absorbable layer is larger than that of the non-absorbable layer, but bo...

Abstract

The invention relates to a patch special for an esophageal hiatus hernia. The patch special for the esophageal hiatus hernia comprises a polyL-lactide-PLCL absorbable layer and a polypropylene non-absorbable layer bonded to the absorbable layer, wherein the outer surface of the absorbable layer faces the stomach, and the outer surface of the non-absorbable layer faces the diaphragm muscle. The non-absorbable layer and the absorbable layer have the same or similar contour shape and are both of a hollow circle structure, and the distance from the edge of the non-absorbable layer to the edge of the absorbable layer is 2-6 mm. The patch special for the esophageal hiatus hernia does not need to completely wrap the esophagus, and overcomes the defects that peristalsis of the esophagus is limited, so dyskinesia of the esophagus is caused and a swallowing function after an operation is affected. The patch special for the esophageal hiatus hernia can completely make contact with the visceral organ and is good in tissue adaptability.

Description

technical field [0001] The invention relates to the technical field of hernia mesh, more specifically, the invention relates to a special mesh for esophageal hiatal hernia. Background technique [0002] Hiatal hernia refers to a disease caused by internal organs (mainly the stomach) entering the chest cavity through the esophageal hiatus of the diaphragm. It mostly occurs in middle-aged and elderly people over the age of 40. The incidence rate reported in China is about 3.5%, and the incidence rate reported in foreign countries About 4.5%-15%. Common clinical manifestations of patients with hiatal hernia include: retrosternal burning pain, acid reflux, belching, chest tightness, dysphagia, upper abdominal discomfort after eating, etc. The clinical symptoms of simple sliding hiatal hernia can be improved after conservative medical treatment. For patients with sliding and other types of hiatal hernia who fail conservative treatment, surgical treatment is required. [0003] I...
