Abstract
A device to provide a volume in a lumen for endoscopic procedures is provided. The device comprises a plurality of flexible tube linkages, said each flexible tube linkage having a distal end and a proximal end, an actuation and locking mechanism comprising an actuation wire, wherein the proximal end of the each flexible tube linkage is connected to the actuation and locking mechanism, wherein the actuation wire is connected about the distal of the each flexible tube linkage, and wherein the actuation wire is arranged to rotate relative to the actuation and locking mechanism so as to define the volume.
Claims12
A device to provide a three-dimensional volume at a workspace in a body lumen comprising:
- a plurality of flexible tube linkages, each one of the plurality of flexible tube linkages having a distal end and a proximal end;
- and
- an actuation and locking mechanism comprising an actuation line, an actuation base having a threaded hole, an actuation rod having a screw portion and a lock key, said screw portion arranged to engage the threaded hole, and a locking cap having a key slot, said key slot arranged to engage the lock key to place the actuation and locking mechanism in a locking position;
- wherein the proximal end of each of the plurality of flexible tube linkages is coupled to the actuation and locking mechanism,
- wherein a distal end of the actuation line is connected to the distal ends of each of the plurality of flexible tube linkages, and
- wherein the actuation and locking mechanism is arranged to rotate relative to the plurality of flexible tube linkages to pull the distal end of the actuation line towards the actuation and locking mechanism thereby moving the distal end of each of the flexible tube linkages towards the proximal end of each of the flexible tube linkages thereby converting the plurality of flexible tube linkages from a closed collapsible structure for transportation to the workplace to a three-dimensional structure defined by the plurality of flexible tube linkages to define the three-dimensional volume at the workspace in the body lumen.
