Abstract
A design is described herein for rings and for cutting rings for a device used in capsulotomy procedures. A set of ring dimensions can describe a desired height of a ring at each location of the ring. The set of ring dimensions is also associated with an intended wall thickness, and thus is associated with an intended cross-sectional area at each ring location. A wall thickness at each portion of a can vary from the intended wall thickness specified by the set of ring dimensions at various locations of the ring. At these locations, the height of the ring can be varied such that the resulting cross-sectional area of the ring at these locations is substantially similar to the intended cross-sectional area of the ring at the locations.
Claims21
A ring for use in surgical operations, the ring corresponding to a ring design specifying, for each of a plurality of locations of the ring, a target width and a target height of the ring at the location, wherein the ring, when cut from a cylindrical medium, comprises an actual height and an actual width for at least a first location of the plurality of locations that differ from the target width and the target height at the first location such that an actual cross-sectional area of the ring at the first location is substantially similar to a target cross-sectional area of the ring, wherein the actual cross-sectional area of the ring at the first location is determined based on the actual height and actual width of the ring at the first location and wherein the target cross-sectional area of the ring at the first location is determined based on the target height and the target width of the ring at the first location.
A method for cutting rings from a tube for a capsulotomy device, the method comprising:
- receiving a set of ring dimensions describing a height of a ring at each location of the ring;
- measuring a wall thickness at each portion of the tube;
- identifying a first set of portions of the tube where the wall thickness is less than a first predetermined thickness threshold;
- identifying a second set of portions of the tube where the wall thickness is greater than a second predetermined thickness threshold;
- modifying the set of ring dimensions of the ring by:
- increasing the height of the ring at one or more locations of the ring corresponding to the first set of portions of the tube;
- and
- reducing the height of the ring at one or more locations of the ring corresponding to the second set of portions of the tube;
- and
- cutting the tube using the modified set of ring dimensions to form the ring.
A non-transitory computer readable medium storing computer code comprising instructions for cutting rings from a tube for a capsulotomy device that, when executed by one or more processors, cause the one or more processors to perform steps comprising:
- receiving a set of ring dimensions describing a height of a ring at each location of the ring;
- measuring a wall thickness at each portion of the tube;
- identifying a first set of portions of the tube where the wall thickness is less than a first predetermined thickness threshold;
- identifying a second set of portions of the tube where the wall thickness is greater than a second predetermined thickness threshold;
- modifying the set of ring dimensions of the ring by:
- reducing the height of the ring at one or more locations of the ring corresponding to the first set of portions of the tube;
- and
- increasing the height of the ring at one or more locations of the ring corresponding to the second set of portions of the tube;
- and
- cutting the tube using the modified set of ring dimensions to form the ring.
A system comprising:
- one or more processors;
- and
- a memory configured to store computer code comprising instructions for cutting rings from a tube for a capsulotomy device, the instructions, when executed by the one or more processors, cause the one or more processors to perform steps comprising:
- receiving a set of ring dimensions describing a height of a ring at each location of the ring;
- measuring a wall thickness at each portion of the tube;
- identifying a first set of portions of the tube where the wall thickness is less than a first predetermined thickness threshold;
- identifying a second set of portions of the tube where the wall thickness is greater than a second predetermined thickness threshold;
- modifying the set of ring dimensions of the ring by:
- reducing the height of the ring at one or more locations of the ring corresponding to the first set of portions of the tube;
- and
- increasing the height of the ring at one or more locations of the ring corresponding to the second set of portions of the tube;
- and
- cutting the tube using the modified set of ring dimensions to form the ring.
