BENDABLE, TELESCOPIC, AND FLEXIBLE CONTINUUM MECHANICAL STRUCTURE

摘要

A bendable, telescopic, and flexible mechanical structure comprises: a distal-end structure body, a proximal-end structure body, and a middle connecting body. The distal-end structure body comprises a distal-end spacing disc, a distal-end locking disc and a structure bone. The proximal-end structure body comprises a proximal-end spacing disc, a proximal-end locking disc and the structure bone. The middle connecting body comprises pipe fixing plates and a pipe. The distal-end structure body is connected to the proximal-end structure body through the middle connecting body. One end of the structure bone is fixed on the proximal-end locking disc. Then, the structure bone passes through the proximal-end spacing disc, the middle connecting body and the distal-end spacing disc sequentially, and is fixed on the distal-end locking disc.

1. A flexible continuum mechanical structure, wherein the flexible continuum mechanical structure comprises:
a distal structure, comprising distal spacer discs, a distal locking disc and backbones; a proximal structure, comprising proximal spacer discs, a proximal locking disc and backbones, and the backbones of the distal structure being fixedly connected with the corresponding backbones of the proximal structure or being the same backbones of the proximal structure; and a connecting structure, comprising cannulae fixation plates and cannulae, wherein the distal structure is associated with the proximal structure through the connecting structure, one end of the backbone is fixed on the proximal locking disc and sequentially passes through the proximal spacer discs, the connecting structure and the distal spacer discs, and the other end is fixed on the distal locking disc, such that when the proximal structure is driven to be bent towards any direction, the distal structure is correspondingly bent towards an opposite direction, or when the proximal structure is driven to be extended or retracted, the distal structure is correspondingly retracted or extended.
