Abstract
A growable continuum instrument includes a growable tube and one or more serially connected continuum structures. The growable tube includes an inner layer, an outer layer, and a fluid chamber between the inner and outer layers. The growable tube includes a turnable region where the inner and outer layers are connected and turnable. The continuum structure is located in the growable tube. The continuum structure includes a plurality of spacer discs and a plurality of connecting structures. The connecting structure includes one or more flexible structural bones, the two ends of which are respectively fixedly connected with the adjacent spacer discs, and are distributed along the circumferential direction of the spacer discs. The plurality of connecting structures include at least a first and second connecting structures, and the flexible structural bones of the first and second connecting structures are distributed differently along the circumferential direction of the spacer disc.
