AI Technical Summary

Technical Problem

The existing laparoscopic training modules cannot effectively simulate the anatomical structures around the esophagus and gastric fundus, resulting in greater surgical difficulty and a longer learning curve for beginners when performing hiatal hernia surgery.

Method used

A laparoscopic practice module was designed, comprising a base, an esophageal hiatus model block, and a gastric module. The module is slidably connected to the esophageal hiatus model block through an opening on the base. Combined with a clamping mechanism consisting of a clamping plate and an adjusting screw, it simulates the operation of dissecting the esophagus and gastric fundus under a laparoscope, providing stability and detachability.

Benefits of technology

It shortens the learning curve for beginners to perform hiatal hernia surgery, improves their surgical skills, and enhances the stability and practicality of simulation training.

Abstract

The utility model relates to the technical field of endoscope practice modules, in particular to an endoscope practice module for simulating hiatus hernia, which comprises a placing frame, the endoscope practice module for training is placed outside the placing frame, and the endoscope practice module comprises a base, a hiatus model block and a stomach module. The endoscope exercise module comprises a base, an esophageal crack hole model block and a stomach module, an opening in the base corresponds to an opening hole of the esophageal crack hole model block, a channel is provided for sliding connection of the esophageal module, the endoscope exercise module is placed in the placing frame, and then two instruments used for sewing are in contact with the endoscope exercise module through two round holes of the placing frame; the endoscope practice module can simulate free esophagus and stomach fundus under an endoscope, meanwhile, a practicer can conduct diaphragm foot suturing operation conveniently, the learning curve of a surgeon for conducting a hiatus hernia operation is shortened, and then the skill mastering level of the practicer for actual operation operation is improved.
