Minimally invasive surgery is generally painless because minimally invasive surgery requires anesthesia, but the type of anesthesia used varies depending on the site of surgery. If you are doing thoracic or laparoscopic surgery, you generally have to have intravenous general anesthesia to do it, and there is no pain in this case. In the case of hysteroscopy, minimally invasive surgery of the urinary tract and arthroscopic surgery of the lower extremities, it is usually treated with lumbar anesthesia or combined lumbar and rigid anesthesia, which generally does not produce pain. In the case of minor surgery for breast fibroids or vertebroplasty of the spine, such cases usually do not need to be performed through general or lumbar anesthesia, and can be done with local anesthesia, which may be a little painful if it is local. But no matter what kind of minimally invasive surgery, because the trauma after the surgery is relatively small and the wound is very small, the pain after the surgery is not as obvious as the usual open surgery, so the pain can be relieved by taking painkillers and there is no need to play painkillers.
