Abstract
An anastomotic instrument (201) and a method for establishing an end-to-side anastomosis. The instrument includes an anvil assembly (202A, 203, 203A), having stapling recesses (204), a clamping assembly (205B, 205A) adapted to be advanced towards the rear face of the anvil (203), and a stapling assembly (206, 206A), to be moved towards the anvil (203). All three assemblies can be split along a common dividing surface, and during the operation, the separable parts of the assemblies are held together by a common elastic rubber sheath (410), to ensure a correct sequence of relative movement when the three assemblies are pressed together by a manual implement having jaws (202C, 206C). After the anastomosis has been established, the rubber sheath (410) may be cut open to enable the separable parts to be separated from each other.
