Hernia Prosthesis for the Treatment of Inguinal Hernias

Abstract

The invention relates to a surgical prosthesis which is intended for the treatment of inguinal hernias. The inventive prosthesis has been provided with a novel structural design, in the form of a loop, which is based primarily on the natural anatomical form of the human body. The prosthesis is intended to protect weak points in the abdominal wall, such as the internal inguinal orifice and all of the posterior wall of the inguinal canal, such that, using only one prosthetic part, the loop prosthesis can be used to repair the two most frequent types of inguinal hernias with maximum safety and effectiveness.

1 . Improved prosthesis for the surgical treatment of groin hernias, characterised in that it comprises a laminar development piece provided with a middle bisecting line partly separating two asymmetric parts forming two halves, so that in principle by folding the right-hand half is superimposed over the left-hand half initiating the formation of the loop, which for completion requires the raising of the lower left-hand tab to superimpose it on the lower right-hand tab, forming a central cavity in the form of an anatomical ring facing the patient's weak areas which cause the two most common forms of inguinal hernias.  
   
   
       2 . Improved prosthesis for the surgical treatment of groin hernias according to the previous claim, characterised in that the folding of the two halves of the laminar piece forms two areas of increased strength, achieved by the double wall of the laminar piece, which correspond to two triangular areas matching up with the anatomically weak areas, with the incorporation of a spermatic cord ensheathed through the folding of the loop and accommodated in the central cavity of same, facing the posterior wall that it is aimed to reinforce, as well as the anatomical ring through which said spermatic cord emerges, which it encircles to form an artificial ring.  
   
   
       3 . Improved prosthesis for the surgical treatment of groin hernias characterised in that its loop configuration gives rise to a helical development that confers a dynamic aspect on it restraining the movements of the muscles, whereby permitting a single prosthetic piece to resolve the two most common types of hernia.
