What is a hernia?

  After more than 100 years of research, there is only one effective treatment for hernias as a common condition, and that is surgery. The choice of surgical procedure is largely mature for adults and children. Adults use a tension-free repair, or a filling repair, and children use a high ligation of the hernia sac.  However, for young adults in their late teens and early twenties, especially those who are unmarried or infertile, the traditional procedure faces a dilemma: if a high ligation of the hernia sac is used, it is prone to recurrence; if a tension-free repair is used, it tends to affect the patency of the vas deferens, which may have a negative impact on fertility.  In order to solve this problem, Bard has adopted the anti-adhesion patch as a solution. However, the anti-adhesion patch has its inherent disadvantages, one of which is that it is less resistant to infection, and the other is that the anti-adhesion layer will not be absorbed and will eventually be wrapped in tissue, so that the cause of the vas deferens is not completely removed.  In response to the shortcomings of the anti-adhesion patch, we designed a new two-layer surgical patch, the lower layer of which is a partially absorbable patch from Johnson & Johnson, to minimize the patient’s discomfort. The upper layer is an absorbable anti-adhesive film, which has an absorption time of about six months. The anti-adhesive film is used to wrap the spermatic cord at the time of surgery to prevent it from being wrapped in scar tissue after surgery. The patch can be completely fused with the tissue in about three months after surgery, after which the local inflammatory reaction gradually subsides and the scar reconstruction can be completed in about six months. At this time, the anti-adhesive material is also absorbed and the spermatic cord is free from the effects of surgery.
