Abstract
In one embodiment, an assembly includes a retractor () and at least one cylindrical rod () attached to the retractor. The rod has a fixed length portion () and a spring portion (). The spring portion of the rod has a longitudinal dimension that changes as a function of loading on the rod. When the rod is in contact with a solid surface such as a bone, it maintains contact with such surface even while changing shape due to loading on the rod. When the assembly includes multiple rods attached to the retractor, both spring-based rods and other types of rods may be used in combination.
