AI Technical Summary

Technical Problem

Existing non-absorbable repair materials increase the risk of postoperative wound infection and foreign body reaction during clinical surgery, and laparoscopic surgery is difficult to perform, especially due to the narrow space and high operational requirements.

Method used

The absorbable metal hernia repair patch, made of magnesium or magnesium alloy, is made by extrusion rolling and annealing to reduce hardness, and is designed with mesh and outer contour. Combined with polishing and sterilization, it is integrated with the protective tube and limiting rod structure in the laparoscopic operating system to simplify the implantation process.

Benefits of technology

This approach achieves biocompatibility and flexibility in the repair patch, reduces the risk of postoperative complications, simplifies laparoscopic surgery, and shortens surgical time and costs.

Abstract

The application discloses a preparation method of absorbable metal hernia repair patch and a laparoscopic operation system, and belongs to the technical field of medical devices. The preparation method of the absorbable metal hernia repair patch comprises the following steps: selecting magnesium and magnesium alloy ingots as base materials; the base materials are extruded and rolled into plate materials; the plate materials are annealed in an annealing furnace at a temperature of 150 DEG C to 200 DEG C for 1 h to 2 h, taken out and flattened to form magnesium plates, and the thickness of the magnesium plates is 0.05 mm to 0.5 mm; cutting equipment or stamping equipment is used to process the mesh holes and the outer contour on the magnesium plates to form a rough hernia repair patch, the mesh hole ratio of the patch in the rough hernia repair patch is 0-70%, and the outer contour is provided with a wavy edge or a round corner; and the rough hernia repair patch is polished, cleaned, packaged and sterilized to obtain the absorbable metal hernia repair patch. The application can not only be absorbed by the human body, but also has good flexibility, can be bent along with the human abdominal wall tissue, is convenient to store and implant in the body.
