  • Patent number: 12279991
    Abstract: Apparatus and method for interfacing an ophthalmic surgical laser system with a patient's eye using a single-piece patient interface (PI). The PI includes a hollow shell, with an applanation lens and a flexible skirt at its lower end. Through channels are formed around the applanation lens to connect the spaces above and below the lens. When the PI is coupled to the laser system and the eye, the upper rim of the shell forms a seal with the laser system and the flexible skirt forms a seal with the eye. A vacuum is applied to the interior of the shell via a vacuum port on the laser system, and the vacuum is communicated to the space enclosed by the applanation lens, the skirt and the eye through the channels around the lens. A magnetic mechanism is also provided to hold the PI shell to the laser system.

  • Publication number: 20250090379
    Abstract: A single-piece patient interface device for coupling a patient's eye to an ophthalmic surgical laser system includes a cone substrate with a rigid frustoconical shaped shell for coupling to the laser system, and a flexible suction ring integrally joined to the lower end of the rigid shell for coupling to the patient's eye. The suction ring has a circular skirt extending downwardly from a base portion, a diaphragm extending from the base portion and disposed inside of the skirt, and a contact lens held by the diaphragm to cover a center opening. When the skirt contacts the eye's surface, the skirt, the diaphragm, the contact lens and the eye surface form a vacuum chamber, where a vacuum may be applied to secure the patient interface device to the eye. The parameters of the suction ring are optimized to fit a large range of eye sizes, including smaller eyes.

  • Patent number: 12129650
    Abstract: An assembly for bracing a non-structural building component mounted adjacent a surface of a building. The assembly has a rigid elongate member, and first and second mounts. In use, the assembly is to be installed between the surface and the non-structural component, with the first mount secured by a fastener to one of the building and the non-structural component, the second mount secured by a fastener to the other of the non-structural component and the building, and the elongate member extending between the first and second mounts and rigidly fixed thereto. The first mount includes an attachment portion, and a connecting portion that is rigidly joined to the attachment portion and that projects away from the attachment portion.

  • Publication number: 20240328442
    Abstract: A beam clamp for attachment to a flange of a structural building member and from which to support or brace a service component. The beam clamp has a clamp body, and a set screw. The clamp body includes a first jaw section with at least one mounting through hole, a second jaw section, a joining section that interconnects the first and second jaw sections, and a transverse opening that is to receive the flange. A contact surface, on the second jaw section is formed with surface irregularities providing a roughness that enhances engagement of the contact surface with the flange. In use of the beam clamp, the contact surface is in contact with the flange of the structural member, the set screw is installed in the mounting through hole, and the flange is screwed within transverse opening between the tip of the set screw and the contact surface.

  • Publication number: 20240315873
    Abstract: A method used in a corneal lenticule procedure for finding the visual axis location before eye docking, to track the visual axis location displacement during docking, and to center the lenticule incision pattern at the visual axis location after docking, without ink-marking the visual axis location at the center of the cornea with ink or other substance. Two docking illumination beams are illuminated on the eye surface at oblique angles, and a first eye image is taken before docking while the eye looks at the fixation light of the laser system. A second eye image is taken after docking. The pre-docking cornea apex position is obtained based on the two reflected light spots of the docking illumination light. Pupil center is obtained in both images. The post-docking corneal apex is then calculated from the pre-docking cornea apex position and the pre- and post-docking pupil center positions.

  • Publication number: 20240151024
    Abstract: A modular framing system has a plurality of spanning members, at least some of which are hollow and have a predetermined nominal wall thickness, fasteners, and a plurality of joiners that are each securable to two or more of the hollow spanning members. Each joiner has connection portions, and at least one web portion that interconnects an adjacent pair of the connection portions, and has a minimum thickness that is greater than the predetermined nominal wall thickness of the hollow spanning members. Each connection portion has through holes for fasteners to secure the joiner to spanning members. The web portion spaces the respective adjacent pair of connection portions, and spanning members secured to the adjacent pair of connection portions are non-parallel and lie in a common plane.

  • Patent number: 11957412
    Abstract: An imaging system for an ophthalmic laser system includes a prism cone made of a transparent optical material and disposed downstream of the focusing objective lens of the ophthalmic laser system, the prism cone having an upper surface, a lower surface parallel to the upper surface, a tapered side surface between the upper and lower surfaces, and a beveled surface formed at an upper edge of the prism cone and intersecting the upper surface and the side surface, and a camera disposed adjacent to the prism cone and facing the beveled surface. The camera is disposed to directly receive light that enters the lower surface of the prism cone and exits the beveled surface without having been reflected by any surface.

  • Patent number: 11690760
    Abstract: A single-piece patient interface device (PI) for coupling an patient's eye to an ophthalmic surgical laser system, which includes a rigid shell, a flexible suction ring joined to a lower edge of the shell, an applanation lens, and a flexible annular diaphragm which joins the applanation lens to the shell near the lower edge of the shell. The flexible diaphragm allows the applanation lens to move relative to the shell, including to shift in longitudinal and lateral directions of the shell and to tilt. In operation, the surgeon first secures the PI to the patient's eye by hand, and then couples the laser system to the PI by lowering the laser delivery head into the PI shell. During the lowering process, the laser delivery head presses the applanation lens down relative to the PI to applanate the cornea of the eye.
