Prosthesis for hernioplasty with preformed monofilament polypropylene mesh

摘要

A prosthesis for hernioplasty made of a precured monofilament polypropylene mesh of surgical quality and controlled memory, thermally stable and biocompatible, is preformed into the shape of a nail (1) and has a median hole (2) for the passage of the spermatic cord, which is possible with the slit (3) connected to said hole. The optimal rigidity, the absence of the memory typical of the known PPM, the roughness allow a perfect adhesion and fit of the mesh with the contact surfaces with no tendency to crumple. Porosity and monofilament allows a quick fibroplastic infiltration avoiding possible infections; this increases also the mechanical adhesion for the tough reaction of incorporation of the newly formed connective tissue into the mesh, avoiding any displacement and allowing its tension free sutureless implant, so as to avoid complications after the operation and relapses unlike the prostheses of the prior art. Such a prosthesis allows an operation in outpatient way without stay, resuming the normal current home - work activity after few hours and the complete physical recovery without hospitalization after about one week, with great advantages from the social-economic point of view, because of saving the hospitalization costs and avoiding to lose working days. This prosthesis finds particular application in surgical repair of herniae, more particularly in the hernioplasty according to Trabucco's technique.
