| 摘要 |
A surgical instrument has a parallel motion mechanism coupled between an instrument body segment and the instrument's distal end. The parallel motion mechanism changes the end effector's position without changing the end effector's orientation. In an aspect of the invention, the parallel motion mechanism and the body segment have essentially the same cross section so that the parallel motion mechanism can be inserted through a guide tube. In an aspect of the invention, the parallel motion mechanism is telemanipulatively controlled.
