摘要 |
There is provided a guide apparatus for orienting a medical tool relative to and through a remote fulcrum or remote center of motion. The guide apparatus may comprise: at least one crank arm comprising at least a portion of a first hinged coupling for hinged coupling to a stabilizer; at least one link arm comprising at least a portion of a second hinged coupling for hinged coupling to the crank arm at a location spaced from the first hinged coupling; a tool holder for supporting a medical tool on the link arm at a location spaced from the first hinged coupling; wherein the rotational axes of the first and second hinged couplings intersect to define a remote fulcrum. The guide apparatus may be configured to be an open-loop spherical chain or a closed-loop spherical chain. |
