Publication number: 20150066002Abstract: The present invention is directed to a tool having a wrist mechanism that provides pitch and yaw rotation in such a way that the tool has no singularity in roll, pitch, and yaw. A positively positionable multi-disk wrist mechanism includes a plurality of disks or vertebrae stacked in series. Each vertebra is configured to rotate in pitch or in yaw with respect to each neighboring vertebra. Actuation cables are used to manipulate and control movement of the vertebrae. In specific embodiments, some of the cables are distal cables that extend from a proximal vertebra through one or more intermediate vertebrae to a distal vertebra, while the remaining cables are medial cables that extend from the proximal vertebra to one or more of the intermediate vertebrae. The cables are actuated by a pivoted plate cable actuator mechanism.Type: ApplicationFiled: November 10, 2014Publication date: March 5, 2015Inventors: THOMAS G. COOPER, DANIEL T. WALLACE, CHANG STACEY CHANG, S. CHRISTOPHER ANDERSON, WILLIAM DUSTIN, SCOTT E. MANZO

Publication number: 20150051618Abstract: A surgical instrument includes a surgical end effector coupled to an elongate tube and a rod that passes through the elongate tube. A control mechanism coupled to the elongate tube includes an input axle having a first axis of rotation, an idler pulley having a second axis of rotation perpendicular to the first axis, and a lever coupled to the rod and having a third axis of rotation parallel to the second axis. First and second capstans are fixed to the input axle. Cables pass over the idler pulley and are coupled to the lever. Rotating the input axle in a first direction winds a first cable onto the first capstan, rotates the lever, and moves the rod in a second direction. Rotating the input axle opposite the first direction winds a second cable onto the second capstan, rotates the lever, and moves the rod opposite the second direction.Type: ApplicationFiled: August 15, 2014Publication date: February 19, 2015Inventors: S.

Publication number: 20150051619Abstract: A force transmission transmits a force received by two rotational inputs to an output gimbal plate. Two capstans receive the rotational input. The capstans drive cables connected to three levers. A cable is connected directly from each of the capstans to one of two levers. Another cable is connected to both capstans and passes over a pulley rotatably coupled to the third lever. Each of three linkages has a first end coupled to one of the three levers and a second end coupled to the output gimbal plate. Rotation of each of the first and the second input capstans causes the three cables to move the three levers such that there is no net movement of the three seconds ends of the linkages with respect to the center of motion of the output gimbal plate. The output gimbal plate may orient a mechanically actuated surgical tool.Type: ApplicationFiled: August 15, 2014Publication date: February 19, 2015Inventors: Thomas G. Cooper, S. Christopher Anderson

Publication number: 20150047454Abstract: A force transmission transmits forces received by three levers to an input gimbal plate having three support points. The input gimbal play may in turn transmit the force to a wrist assembly coupled to a surgical tool. A first gimbal support point is supported by a first lever having a fulcrum with one degree of rotational freedom. Second and third gimbal support points may be supported by second and third levers having fulcrums with two degrees of rotational freedom. These fulcrums may include a first axle coupled to the lever and a second axle that supports the first axle and provides the fulcrum for the supported lever. A spring may draw the second and third levers toward one another. The force transmission may include a parallelogram linkage that includes a rocker link pivotally coupled to the first lever and having a flat surface that supports the first gimbal support point.Type: ApplicationFiled: August 15, 2014Publication date: February 19, 2015Inventors: Thomas G.

Publication number: 20150051034Abstract: A force transmission includes an input axle having an input axis of rotation that receives a rotational input. An input capstan is fixed to the input axle. An output capstan is fixed to a main tube bushing. The output capstan and main tube bushing have an output axis of rotation that is at an angle to the input axis of rotation. A cable couples the rotation of the input capstan to rotate the output capstan and the main tube bushing. At least one of the input capstan and the output capstan is tapered such that the overall path length of the cable remains substantially the same throughout the range of motion of the capstans.Type: ApplicationFiled: August 12, 2014Publication date: February 19, 2015Inventors: Thomas G.
