More Information
Summary: A robotic surgical instrument comprising an articulation 505 connecting two end effector elements 502,503 to a shaft 504, comprising a supporting body 509 with a bevelled surface. A first joint allows rotation of the supporting body about a first axis 510, and second and third joints allow rotation of the end effector elements about a second axis 512. Pairs of driving elements A1,B2,C1,C2 are configured to drive the joints. A redirecting pulley 717 is mounted on the bevelled surface and rotates about an axis perpendicular to the bevelled surface, the redirecting pulley configured to constrain and redirect about a first side a driving element C1 between the first and the second joint, and on the second side to partially enclose without redirecting a driving element B2 between the first and third joints. A second bevelled surface and redirecting pulley may be located on the opposite side of the supporting body.
