Modified USA 31cm — Hernia Repair in Massive Ventral Hernia
The 31cm-labelled Modified USA dressing forceps serves complex ventral-hernia repair — the operations that address loss-of-domain defects in patients with large incisional hernias following previous abdominal surgery. The 31cm length reaches through the abdominal-wall reconstruction layers needed for these complex repairs, where the surgical team places large prosthetic mesh in a retro-rectus or pre-peritoneal position.
The component-separation technique
Ramirez’s posterior component separation and the more recent transversus abdominis release (TAR) restore midline approximation in patients with previously-irreparable ventral defects. The 31cm Modified USA forceps handles the posterior-rectus-sheath dissection during the TAR component, where the operator works behind the rectus muscle through the entire length of the abdominal wall.
The mesh-placement strategy
Modern ventral-hernia repair uses macroporous polypropylene or biological mesh in a sublay position, with mesh size 5-10cm larger than the defect on each side. The 31cm Modified USA forceps positions and secures the mesh during the retro-rectus or pre-peritoneal placement.
