<p>An implement (1) for surgery is provided with a flexible pouch (2) and is used as follows: said pouch (2) is inserted into a cavity (911) in a vertebral body (91), and with the pouch inserted, the inside of the pouch (2) is filled with a filler (8A). The pouch (2) comprises a mesh and has a coarse-mesh part (24), where the holes in the mesh are large, and a fine-mesh part (25), where the holes in the mesh are smaller than in the coarse-mesh part (24). The present invention makes it possible to both prevent unintended leakage of the filler (8A) from inside the pouch (2) and allow the filler (8A) in the pouch (2) to selectively contact a desired area of the bone.</p> |
