Winding devices are widely used and may include a diverse assortment of implementations and applications. For example, a reel of string, wire, and/or a filament can be dereeled and wound and/or turned onto an object. The filament can be wound onto the object by turning the object around a longitudinal axis of the object. The filament can be wound by winding the filament around the object. The winding can be performed under varying degrees of tension. High tension during winding can result in higher rigidity and strength whereas low tension can result in more flexibility. A filament can be wound onto an object in multiple layers. For example, a first layer can be wound across the object from left to right and then a second layer can be wound from right to left over the first layer.
Winding a wire onto a multi-sided object (e.g., a cube) can be difficult as compared to winding a wire onto a single-sided object (e.g., a cylinder). Winding onto each of the sides of the multi-sided object can include repositioning the multi-sided object to be wound around. Winding the wire with a constant tension on the wire can allow the wire to maintain a location at a winding point along the multi-sided object and efficiently wind the wire by minimizing movement of the wire. The wire can be wound around a plurality (e.g., first set) of sides of a multi-sided object. For example, a wire can be wound around a first set of sides of a cube, such as four sides of the cube.
Further, the wire can be wound around all six sides of the cube by being wound around additional sets of sides of the cube. The winding of the wire around the six sides can include winding a wire in both directions across each of the six sides. For example, a wire can be wound around a first set of four sides of the cube. The cube can be repositioned and the wire can be wound around a second set of four sides of the cube, where the second set includes two sides of the first set. The cube can be repositioned again and the wire can be wound around a third set of four sides of the cube, where the third set includes two sides of the first set and two sides of the second set. See
A multi-sided object with wire wound onto its multiple sides in loops around different axes can be useful for detection of movement, location, and/or orientation of the multi-sided object by electromagnetic sensing. For example, such detection can be useful for medical navigation purposes, such as movement through a physiological area (e.g. medically navigating a blood vessel, an esophagus, physiological tubing, etc.). Such detection can be useful for positioning purposes such as in virtual reality gaming, virtual positioning, positional detection, and other additional industries. Detection of movement, location, and/or orientation of the multi-sided object may be more difficult or inaccurate if wire were wound onto fewer sides of the multi-sided object and/or if the loops were wound around fewer axes of the multi-sided object. For example, precise movements of a multi-sided object used for medical navigation can include movements perpendicular to a longitudinal axis of the multi-sided object, along the longitudinal axis, and varying degrees of movement therebetween. Winding wire onto the multi-sided object in multiple directions and/or onto multiple sets of sides can provide an ability to detect movements in additional directions as compared to wire wound onto the multi-sided object in one direction and/or onto one set of sides. Methods for performing such medical navigation can include electromagnetic tracking and sensing for such medical procedures as guiding endoscopic tools and catheters down a pulmonary tract, radiation oncology to guide implantation of radiosurgical markers and/or fiducials, in addition to other medical uses.

The dereeling control unit 120 can control the rotating of the dereeler axle 118 to dereel the wire 114 off of the spool 112. The system 100 can use different wires 114 of a number of different gauges and/or lengths. Smaller gauges of wire (e.g., wires with greater diameters) can be wound around the multi-sided object 116 fewer times to complete a winding of the wire across one side of the multi-sided object. Larger gauges of wire (e.g., wires with smaller diameters) can be wound around the multi-sided object 116 a greater number of times to complete a winding across one longitudinal length of the multi-sided object 116.
The system 100 can include winding components 102 such as a shaft 130, a positioning component 122 (e.g., a rod), a receiving component 124 (e.g., a cone), and a cylinder 126 coupled to the receiving component 124 (e.g., a component that receives the rod, as illustrated). The positioning component 122 can position the multi-sided object 116 to maintain a particular position while being wound. The receiving component 124 can receive the positioning component 122. The winding components 102 can be controlled and/or rotated by a winding control unit 132. The shaft 130 can rotate, illustrated by arrow 134, about a longitudinal axis 136 of both the shaft 130 and the multi-sided object 116. The winding control unit 132 can rotate the shaft 130 and can be positioned on a flat surface, such as a table. As the shaft 130 rotates, the cylinder 126 and the receiving component 124 also rotates about the same longitudinal axis 136. The cylinder 126 includes a fastener 128 that couples (e.g., immovably fastens, connects, etc.) the receiving component 124 to the cylinder 126. The fastener 128 can be a screw, a pin, and/or any other tightening or securing component. When fastener 128 is tightened, the receiving component 124 is immovable in relation to the cylinder 126 and therefore immovable in relation to the shaft 130.
The receiving component 124 can receive the positioning component 122 through an opening in the receiving component 124. The positioning component 122 can be fastened to the receiving component 124 using the fastener 128. As the receiving component 124 rotates about the longitudinal axis 136, the positioning component 122 that is fastened within the receiving component 124 also rotates. As the positioning component 122 rotates, the wire 114 can be dereeled off of the spool 112 and be wound onto the multi-sided object 116 as the multi-sided object 116 rotates, as illustrated by arrow 115. As the wire 114 is wound onto the multi-sided object 116, the dereeler axle 118 can move from side to side, illustrated by arrow 138 in order to move the wire 114 from a first edge of the sides of the multi-sided object 116 being wound onto toward a second edge of the sides.
As will be described and illustrated in association with
The dereeling control unit 120 can control the side-to-side traversal, illustrated as arrow 138, of the wire 114 by moving the spool 112 from side-to-side a particular distance at a particular rate depending on winding factors (e.g., size of the wire, size of the multi-sided object, etc.). One winding factor is a width of the wire 114. For example, the dereeling axle 118 can be moved, and therefore the spool 112 can be moved, a larger distance side-to-side when winding a wire with a greater width in order to line each loop around the multi-sided object 116 for each rotation of the multi-sided object 116. Vice versa, the spool 112 can move a shorter distance from side-to-side when winding a wire 114 with a lesser diameter onto a multi-sided object 116 due to the wire 114 covering a lesser portion of the multi-sided object in one loop around the multi-sided object during one rotation.
Another winding factor is a width of the multi-sided object 116. The greater the width of the multi-sided object, the slower the dereeling axle 118 moves, as indicated by arrow 138, to complete one loop of the wire around the multi-sided object. This is due to a greater distance along the width of each side taking a greater period of time to travel along and therefore the movement, as indicated by arrow 138, accounts for this greater travel time. In the alternative, the smaller the width of the multi-sided object 116, the faster the dereeling axle 118 moves, as indicated by arrow 138, to complete one loop. The above mentioned speeds are in relation to a constant speed of rotation.
Another winding factor is a speed of rotation of the shaft 130 and therefore the multi-sided object 116. If the speed of rotation is altered, the speeds at which the dereeling axle 118 moves, as indicated by arrow 138, may be affected. For example, a greater rotation speed can cause a speed at which the dereeling axle 118 will move, as indicated by arrow 138, to increase. However, the relative speeds (i.e., faster for smaller widths of the multi-sided object 116 and slower for a greater width of the multi-sided object) remains the same.
The receiving component 224 can be configured to receive a positioning component 222 (e.g., a rod) such that the positioning component 222 is immovably coupled to the receiving component 224. A multi-sided object 116 such as a cube can be slid and/or inserted onto the positioning component 222 such that the positioning component 222 passes through a first corner of the multi-sided object 216 and exits a second corner of the multi-sided object 216 that is furthest from and opposite the first corner. The positioning component 222 can be received by the receiving component 224 at a particular angle such that when the positioning component 222 is rotated, along with the rotating shaft 230, cylinder 226, and receiving component 224, a center point of the multi-sided object 216 maintains a position along the longitudinal axis 236 of the shaft 230 while the multi-sided object 216 rotates around the longitudinal axis 236 of the shaft 230.
As the positioning component 222 rotates around the longitudinal axis 236 of the shaft 230, a first point at which the positioning component 222 enters the receiving component 224 rotates around the longitudinal axis 236 of the shaft 230 in a first orbit 240-1. Further, a second point of the positioning component 222 furthest from the receiving component 224 rotates around the longitudinal axis 236 of the shaft 230, indicated by arrow 234-2, in a second orbit 240-2. The rotating of the multi-sided object 216 on the positioning component 222 causes the wire 214 to be wound, indicated by arrows 215 (including each of four arrows illustrated indicating winding around each of the four sides of the cube), around the multi-sided object 216. The wire 214 can be moved, indicated by arrow 238, from right to left, as illustrated, in order to wind the wire 214 from a first edge of each of a first set of sides of the multi-sided object 216 to a second edge of each of the first set of sides that are each opposite their corresponding first edge. That is, wound from a left edge of each side of the first set of sides of the illustrated cube to a right edge of each side of the first set of sides of the cube.
A first set of four sides, described further below in association with
While the winding components 202 are illustrated as including a shaft, a cylinder, a receiving component, and a rod, embodiments are not so limited. For example, the winding components 202 can include fewer components than are illustrated to wind the wire 214 around all sides of the multi-sided object 216. The winding components 202 can include any number of components that rotate the multi-sided object 216 around the longitudinal axis 236 of the shaft 230 and also rotate, as illustrated at arrow 242, the multi-sided object 216 a particular number of degrees around the longitudinal axis 227 to line up a different set of sides to wind onto. In addition, the rod can be replaced by an additional mechanism to hold the multi-sided object 216 and still be able to accomplish these outcomes. For example, instead of a rod (as illustrated), the positioning component can be a mechanism that holds each of the opposite corners without passing through the multi-sided object. That is, the mechanism could use tension to hold each opposite corner to hold the multi-sided object in a particular position while being wound. As long as the mechanism accomplishes holding the multi-sided object to be wound onto in the way illustrated, the mechanism can be referred to as a positioning and/or winding component, as described herein.
As illustrated in
Subsequent to rotation of the receiving component 324, the receiving component 324 can be fastened by a fastener (e.g., fastener 228) to hold the receiving component 324 in place. As illustrated by arrow 315-2, wire can be wound onto a second set of sides (e.g., sides “5” 350-5, “3” 350-3, “6” 350-6, and “1” 350-1) of the multi-sided object 316 while the multi-sided object is in the second position 306.
