The anastomosis does not affect the aesthetics after it is done. The anastomosis has the advantages of simple and convenient operation, effective reduction of surgical complications and saving of surgical time, which is favorable to the aesthetics of the incision. 1. The anastomosis is a medical alternative to manual suturing equipment, the working principle is the use of multiple rows of metal nails on the dissected tissue suture, similar to a stapler, the various layers of tissue alignment, no tension, conducive to wound healing. 2. When anastomosing tissues, the anastomosis can choose different specifications to cope with different thicknesses of tissues, and it can achieve moderate tightness and tightness of anastomosis, preventing post-surgical bleeding of the incision and other possible secondary infections, which is conducive to wound healing. 3. The anastomosis can be used for one-time anastomosis of large incision, round incision, etc. The anastomosis height is consistent, the spacing of anastomosis nails is even, and the anastomosis nails have little stimulation to the tissues, and the scars are small in the postoperative period.
