Medical mesh for hernia repair patch

Abstract

The invention relates to a medical mesh for a hernia repair patch. The mesh is characterized by adopting medical grade polycaprolactone monofils as weaving material and having a breaking strength of 500 to 700 CN, a breaking elongation of 30 to 100 percent, a knot breaking strength of 400 to 600 CN and a knot breaking elongation of 10 to 50 percent. Besides the basic physical and chemical properties of common polycaprolactone, the medical grade polycaprolactone surpasses the common polycaprolactone regarding the purity, biological stability and biological solubility because the components of parent material and low molecular additives are strictly controlled in the processing process. The polycaprolactone monofils has a higher rigidity and is more suitable for being used to weave the hernia repair patch which has certain strength and bending rigidity and is capable of resisting human body abdominal pressure and defected body pressure.

Description

Technical field [0001] The invention relates to a patch mesh fabric, in particular to a mesh fabric used for medical hernia patches. Background technique [0002] Hernia refers to the formation of a certain tissue or organ in the body from the normal anatomical position, through congenital or acquired weak points, defects or gaps into a part. Among them, external abdominal hernias are the most common, and inguinal hernias are more common, occupying about the abdomen 90%-95% of external hernias. Abdominal hernia is a common disease in surgery, with an incidence of about 1% to 5% of the population. According to the different locations, it can be divided into inguinal hernia, femoral hernia, umbilical hernia, incisional hernia, meniscus hernia, obturator hernia, lumbar hernia and so on. External abdominal hernias generally do not heal on their own. Once incarcerated, early surgical treatment may be endangered. The incidence rate in my country is about 3.47 million cases per year fro...

[0006] Traditional inguinal hernia repair methods, such as Bassin method, Mcvsy method, and Halsted method, because of the irrational high-tension suture of different tissue structures, patients often have severe wound pain, long recovery time, and post-operative recurrence rate It can reach 10%-15%, which brings great pain and inconvenience to the patient
