In order to carry out anastomosis rapidly and reliably a surgical instrument (1) according to the invention is provided with two clamping means (2,3), each being arranged to support a fastening means (5a,5b) consisting of a ring with axially directed pins (6). The clamping means (2,3) are rotatably connected to the instrument and can be actuated by a mechanism (i.a. 7) to be turned towards each other to join the fastening means (5a,5b) and vessels or organs (50,51) threaded onto these.
