Titanium staples do not grow into the foreskin. The titanium staple is an anastomosis that is used during circumcision surgery for phimosis or circumcision. The titanium spike in the anastomosis can replace the traditional suture. The advantage is that it can shorten the operation time, the operation is basically no bleeding, reduce the exposure time of the surgical wound to reduce the chance of infection. Moreover, titanium staples cause less irritation to the tissue compared to sutures, thus helping to promote wound healing. After circumcision using anastomosis, generally titanium nails in the anastomosis start to fall off from about a week after the operation, about half a month to about 20 days can be finished. However, due to individual differences, some people may not be able to fall off until a month or so. Clinically, if the titanium staple cannot be completely dislodged half a month after the operation, it is necessary to go to the hospital for a review, so that the doctor can deal with it according to the specific situation.
