Abstract
The invention provides an articulating mechanism useful, for example, for remote manipulation of various surgical instruments and diagnostic tools within, or to, regions of the body. Movement of segments at the proximal end of the mechanism results in a corresponding, relative movement of segments at the distal end of the mechanism. The proximal and distal segments are connected by a set of cables in such a fashion that each proximal segment forms a discrete pair with a distal segment. This configuration allows each segment pair to move independently of one another and also permits the articulating mechanism to undergo complex movements and adopt complex configurations.
Claims27
An articulating mechanism for remote manipulation of a surgical or diagnostic tool comprising:
- multiple pairs of links, each link of each pair being maintained in a spaced apart relationship relative to the other link of the pair, and
- multiple sets of cables, with each set connecting the links of a discrete pair to one another and terminating at the links of each discrete pair, such that movement of one link of a pair causes corresponding relative movement of the other link of the pair.
An articulating mechanism comprising:
- multiple pairs of links, each link of each pair being maintained in a spaced apart relationship relative to the other link of the pair such that the links form proximal and distal ends with links of corresponding pairs being located on the proximal and distal ends, respectively;
- and
- multiple sets of cables, with each set connecting the links of a discrete pair to one another and terminating at the links of each discrete pair, such that movement of one link of a pair causes corresponding relative movement of the other link of the pair, and movement of the proximal end results in corresponding relative movement of the distal end.
