| 摘要 |
The invention concerns an anatomical structure comprising a flexible foam block (2) and a bone segment suffering from a given pathological condition, for instance a backbone segment (1) affected by spondylolisthesis, embedded in the block (2); the backbone segment (1) is made of a material reproducing the spongy bone and advantageously coated with a material layer reproducing the cortical bone, said materials as well as that constituting the foam being for example polyurethane. The backbone segment (1) comprises a flexible tubular membrane (3) simulating the spinal cord. Said structure constitutes a simulator for training surgeons, reconstituting anatomical elements reproducing sensations experienced during an operation close to reality when they are being manipulated. The invention provides efficient and easy training without the constraints and difficulties encountered with corpses, such that surgeons can be efficiently trained and at reasonable cost.
