  • Patent number: 8409462
    Abstract: A method for manufacturing surgical blades from either a crystalline or poly-crystalline material, preferably in the form of a wafer, is disclosed. The method includes preparing the crystalline or poly-crystalline wafers by mounting them and machining trenches into the wafers. The methods for machining the trenches, which form the bevel blade surfaces, include a diamond blade saw, laser system, ultrasonic machine, and a hot forge press. The wafers are then placed in an etchant solution which isotropically etches the wafers in a uniform manner, such that layers of crystalline or poly-crystalline material are removed uniformly, producing single or double bevel blades. Nearly any angle can be machined into the wafer which remains after etching. The resulting radii of the blade edges is 5-500 nm, which is the same caliber as a diamond edged blade, but manufactured at a fraction of the cost.

  • Patent number: 7785485
    Abstract: A method for manufacturing blades for surgical and other uses from either a crystalline or polycrystalline material, preferably in the form of a wafer, comprises preparing the crystalline or polycrystalline wafers by mounting them and machining trenches into the wafers. The methods for machining the trenches, which form the bevel blade surfaces, include a diamond blade saw, laser system, ultrasonic machine, a hot forge press and a router. When a router is used, through-holes are drilled in the wafer to define the starting locations of the trenches. After the trenches are formed, the wafers are placed in an etchant solution which isotropically etches the wafers in a uniform manner, such that layers of crystalline or polycrystalline material are removed uniformly, producing single or double bevel blades, with each bevel having one or more facets. Nearly any bevel angle can be machined into the wafer which remains after etching.

  • Publication number: 20090007436
    Abstract: Ophthalmic surgical blades are manufactured from either a crystalline or polycrystalline material, preferably in the form of a wafer. The method comprises preparing the crystalline or polycrystalline wafers by mounting them and machining trenches into the wafers. Methods for machining the trenches, which form the bevel blade surfaces, include a diamond blade saw, laser system, ultrasonic machine, a hot forge press and a router. The wafers are then placed in an etchant solution which isotropically etches the wafers in a uniform manner, such that layers of crystalline or polycrystalline material are removed uniformly, producing single, double or multiple bevel blades. Nearly any bevel angle can be machined into the wafer which remains after etching. The resulting radii of the blade edges is 5-500 nm, which is the same caliber as a diamond edged blade, but manufactured at a fraction of the cost.

  • Patent number: 7396484
    Abstract: Ophthalmic surgical blades are manufactured from either a single crystal or poly-crystalline material, preferably in the form of a wafer. The method comprises preparing the single crystal or poly-crystalline wafers by mounting them and etching trenches into the wafers using one of several processes. Methods for machining the trenches, which form the bevel blade surfaces, include a diamond blade saw, laser system, ultrasonic machine, a hot forge press and a router. Other processes include wet etching (isotropic and anisotropic) and dry etching (isotropic and anisotropic, including reactive ion etching), and combinations of these etching steps. The wafers are then placed in an etchant solution which isotropically etches the wafers in a uniform manner, such that layers of crystalline or poly-crystalline material are removed uniformly, producing single, double or multiple bevel blades. Nearly any angle can be machined into the wafer, and the machined angle remains after etching.

  • Patent number: 5786153
    Abstract: A method for substantially preventing coating of hydrophobic material on a probe of an automated analyzer during an assay is described. An automated analyzer having a probe is provided. A composition comprising a non-denaturing surfactant and a reagent for use in the assay is provided. The probe is contacted with the composition during the assay such that hydrophobic material is substantially prevented from coating the probe on the automated analyzer. Compositions for preventing such probe coating are also described. Methods and compositions comprising a non-denaturing surfactant for enhancing the stability of reagents used in an assay are also described.
