The lumen permits the passage of surgical instruments from the proximal end of the endoscopic device to the operation site. The lumen extends beyond the distal end of the endoscope and deflects at the distal end as desired by the operator's manipulation of a controller device. This distal end deflection may occur through various different techniques where the ability to deflect the lumen gives the operator increased control and maneuverability over the surgical implements located in the lumen. Depending upon the particular requirements of the surgical procedure, the controllable sheath may include any number of lumens capable of distal end deflection. | 09-12-2013 |

20150141756 | CONTINUUM STYLE MANIPULATOR ACTUATED WITH PHASE CHANGE MEDIA - A continuum style manipulator is actuated by jammable media within an envelope of a module, which is also actuated by a tensile element, such as a cable and spooler motor. Multiple modules may be reversibly added. Two or more tensile elements may also be used. Three or more actuated tensile elements can actuate three DOFs of each module, and the terminal module, as well as the entire manipulator. Jammable media may be granular, actuated by a pressure change. Coarsely ground coffee works well. Rather than a jammable media, tensile elements may alternatively be used with other phase change media, such as magnetorheological and electrorheological media. A high friction angle of the granular media is desirable, and has been achieved with a particle size dispersion including both small and relatively larger particles. Applications include endoscopes, proctoscopes, laparoscopic instruments, manufacturing and medical manipulators. Methods of actuating include unjamming all modules, positioning the manipulator with tensile elements or otherwise, jamming the base-most module, and then repositioning remaining, not-jammed modules, followed by jamming the base-most not-jammed module, and so on, until all modules are positioned and jammed. | 05-21-2015 |
