Abstract
In surgery, especially in microsurgery, the joining of blood vessel ends or other tubular organs, anastomosis, consumes a considerable part of the time. In order to carry out anastomosis rapidly and reliably a surgical instrument (1) according to the invention is provided with two clamping members (2,3), each being arranged to support a fastening structure (5a,5b) comprising a ring with axially directed pins (6). The clamping members (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 structure (5a,5b) and vessels or organs (50,51) threaded onto these. The invention also relates to fastening devices (5a,5b) shaped in such a manner that they are retained in the clamping means (2,3) of the instrument until the joining has taken place.
