Description

Can be fitted with supporting elastic mesh hernia repair mesh

technical field

The invention relates to the technical field of medical devices, in particular to an assembling and supporting elastic coil hernia repair mesh.

Background technique

At present, a considerable number of patients have undergone laparoscopic repair of parastomal hernia and abdominal wall incisional hernia, and the operation is quite difficult and complicated. It is a pity that a considerable number of patients have hernia recurrence after surgery, especially for patients with parastomal hernia, the recurrence rate after surgery can reach 50%. Postoperative recurrence has caused serious physical and mental trauma to patients, as well as a heavy economic burden. .

It is generally believed that the main cause of recurrence is the shrinkage and displacement of the anti-adhesion mesh repaired and sutured to the abdominal wall, thereby losing its barrier function. The main reason for shrinkage and displacement is that there is no bony or strong ligamentous tissue in the middle part of the abdominal wall to fix and support the mesh. Therefore, anti-adhesion hernia repair mesh sheets with pre-set supporting elastic rings appear on the market, and good effects of preventing mesh sheets from shrinking and shifting have been achieved. However, the opening plane of the anti-adhesion mesh sheet with the support elastic ring is too large and cannot be curled and reduced. It can only be placed in the abdominal cavity for repair during open surgery, and cannot be placed into the abdominal cavity through the puncture sheath in laparoscopic surgery. , can not be applied to laparoscopic minimally invasive surgery, and laparoscopic minimally invasive surgery has become the main surgical method at present.
