ARTICULATABLE MEMBERS HAVING CONSTRAINED MOTION AND RELATED DEVICES AND METHODS |
| 摘要 |
An articulatable member includes a distal end, a proximal end, an actuation member, and a constraint member. The actuation member extends from the proximal end to the distal end. The actuation member transmits force to bend the articulatable member from a neutral position. The constraint member extends from the proximal end to the distal end. The constraint member may have opposite ends that are fixed to the distal end and the proximal end. In one embodiment, the constraint member follows a helical path along at least a portion of the articulatable member from the proximal end to the distal end. In another embodiment, the actuation member follows a helical path along at least a portion of the articulatable member. |

1. An articulatable member, comprising:
a distal end; a proximal end; an actuation member extending from the proximal end to the distal end, wherein the actuation member transmits force to bend the articulatable member from a neutral position; and a constraint member extending from the proximal end to the distal end, the constraint member having opposite ends that are fixed to the distal end and the proximal end, respectively; wherein the constraint member follows a helical path along at least a portion of the articulatable member from the proximal end to the distal end. |
