Disclosed is a splint-like element for use in endto-end nerve suture to eliminate tension at the anastomosis site and thus allow optimal coaptation between the nerve ends to be sutured. The element comprises an elongated body made of a material that is rigid and slightly resilient and is biologically acceptable, such as silicone, The body is long enough to have one end attachable to the epineurium of one of the nerve ends by at least one but preferably two longitudinally spaced-apart sutures, and another end attachable to the epineurium of the other nerve end also by at least one but preferably two other longitudinally spacedapart sutures. The element also comprises pieces of reinforcing material preferably consisting of beads of plastic material embedded into the body material wherever this body is intended to be attached to the epineurium to prevent the body material from being torn or otherwise cut by the sutures. In use, two such splint-like elements may be attached symmetrically to the epineurium of the nerve ends while the same are held into contact in order to make the suture site tension free. Then, the nerve ends may be sutured as is known in the medical art to achieve the requested anastomosis. |
