Complex surgical device for carrying out and protecting an anastomosis

A surgical device that is a ready-to-use assembly for performing an anastomosis in the intestine with an anvil and a circular stapler and protecting said anastomosis in the intestine, the device comprising:

• (a) a protective device comprising an anchor element consisting of at least one stent capable of being temporarily anchored to the inner wall of the intestine upstream of the anastomosis and a flexible sheath, at least the upstream end of which is fixed to said stent, said sheath being capable of extending downstream of said anchor element and downstream of said anastomosis in order to allow said anastomosis to be protected, and
• (b) at least a first tube, called first guide tube, said stent being held in radial compression inside said first guide tube, at a distal end of said first guide tube, said first guide tube being part of a guide tube of an introducer device, or being reversibly attachable to an introducer device, said first guide tube being deformable in curvature with respect to its longitudinal axis,
• wherein said flexible sheath is folded inside said first guide tube, the downstream end of said sheath being connected to said first guide tube, or to a first connection piece independent of said first guide tube, said sheath being able to be deployed downstream of said stent by withdrawing the proximal end of said first guide tube or to said first connection piece to which it is fixed, and
• wherein said first guide tube, or said first connecting piece, comprises a reversible fixing means to enable the proximal end to be reversibly fixed to said anvil.
