Abstract: A new anastomat for digestive tract operations, based on the magnetic compressive technique and mechanical transmission mechanism, is composed of a removable head and a reusable body. The head includes two parts: the proximal end can be fixed to the body, and the distal end could be used for performing a purse string suture. The procedure of anastomosis is similar to that of the stapler, and the anastomoses is established using a pair of magnetic rings. The instrument makes magnamosis more simple and feasible, and it would facilitate the clinical applicaion. The body of the anastomat is reusable and the head could be replaced according to the clinical scenarios, these could reduce the medical cost. The magnetic rings would be excreted with the feces, and there is no foreign body response at last.
