Technical field
This utility model belongs to medical instruments field, particularly relates to a kind of hernia containing nano-titanium and repairs sticking patch.
Technical background
Tension-free hernioplasty is the main flow art formula of clinical treatment hernia disease, uses hernia patching material based on polypropylene material, has good tension stress and creasing resistance.Polypropylene hernia is repaired sticking patch and be there is following problem: polypropylene material hydrophilic is poor, pliability is poor, and doctor is inconvenient with laparoscopic surgery operation.Material surface compares extra coarse, high hydrophobicity, and intestinal tube directly contacts and more serious intestinal adhesion can occur, and even causes intestinal fistula, once there are the problems referred to above, needs sticking patch to take out, performs the operation more loaded down with trivial details.
In recent years, nanotechnology has been widely used in the science and technology such as medical treatment, food, image.Nano-particle is extremely small, and specific surface area is comparatively large, makes it have good skin effect and quantum size.Show according to the study, nano titanium oxide can form firmly interface cohesion with matrix, the shortcoming of matrix surface pliability difference can be improved, nano titanium oxide has good biocompatibility, also there is super wettability, excellent blood compatibility, and wear-resistant corrosion resistance, can be used as the material of implant into body.In this utility model patent by nano-titanium load in mesh sheet, based on nano-titanium, there is excellent hydrophilic, solve the shortcoming of mesh sheet sheet rough surface, low hydrophilic, pliability difference, obtain good biological activity.
Utility model content
The purpose of this utility model is the problems referred to above being to exist for prior art, provides a kind of hernia containing nano-titanium and repairs sticking patch, solve the deficiency of coarse, the low hydrophilic of existing patch faces, pliability difference.
This utility model is mainly undertaken solving by following technical proposals:
Hernia containing nano-titanium repairs a sticking patch, comprises mesh sheet basic unit and is arranged on nanometer titanium dioxide layer in mesh sheet basic unit.
Mesh sheet basic unit as above be polypropylene, polyethylene, polyester, politef, PGA, poly (glycolide-lactide), polyglycolic acid, polylactic-co-glycolic acid one or more.
In mesh sheet basic unit as above, the load capacity of nanometer titanium dioxide layer is 0.1-3.0mg/cm
2.
The particle diameter of the titanium dioxide in nanometer titanium dioxide layer as above is 5-60nm.
The aperture of mesh sheet basic unit as above is 0.5-2.0mm, and the thickness of mesh sheet basic unit is 0.1-2.0mm.
