    • 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. 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. A range of radii may be 30 to 60 nm, with a specific implementation being about 40 nm. The blade profile may have an angle of, for example, about 60. The ophthalmic surgical blades can be used for cataract and refractive surgical procedures, as well as microsurgical, biological and non-medical, non-biological purposes. Surgical and non-surgical blades and mechanical devices manufactured as described herein can also exhibit substantially smoother surfaces than metal blades. ® KIPO & WIPO 2007
    • 眼科手术刀片由单晶或多晶材料制成,优选为晶片形式。 该方法包括通过使用几种方法之一安装它们并将沟槽蚀刻到晶片中来准备单晶或多晶晶片。 用于加工形成斜面刀片表面的沟槽的方法包括金刚石锯片锯,激光系统,超声波机器,热锻压机和路由器。 其他工艺包括湿蚀刻(各向同性和各向异性)和干蚀刻(各向同性和各向异性,包括反应离子蚀刻)以及这些蚀刻步骤的组合。 然后将晶片放置在蚀刻剂溶液中,其均匀地蚀刻晶片,使得均匀地去除晶体或多晶材料层,产生单个,双重或多个斜面叶片。 几乎任何角度可以加工到晶片中,并且在蚀刻之后保留加工角度。 叶片边缘的最终半径为5-500nm,其与金刚石边缘刀片相同的口径,但是以成本的一小部分制造。 半径范围可以为30至60nm,具体实施方案为约40nm。 刀片轮廓可以具有例如约60°的角度。眼科手术刀片可用于白内障和屈光手术,以及显微手术,生物和非医学,非生物学目的。 如本文所述制造的手术和非手术刀片和机械装置也可以表现出比金属刀片更基本平滑的表面。 ®KIPO&WIPO 2007

    • A surgical knife safety device (10 or 100) having a handle (20 or 120), a blade (40 or 140) connected to the handle, and a guard (30 or 130) carried by the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an enlarged guard (30 or 130) radius is provided at the distal end of the handle (20 or 120) to allow improved handle control and blade orientation. The enlarged guard radius is positioned to allow the user to firmly grip a large distal handle portion which is preferably molded as a single piece with the blade holder (26 or 126), preventing unwanted blade or handle movement due to guard mechanism tolerances. A spring, such as leaf spring or a cantilever beam (52 or 152), and a pair of detents (54, 56) or slots (154, 156) are provided to fix the guard (30 or 130) in the extended or retracted position and to provide resistance during movement between the two positions. Additionally, a pushback prevention mechanism, a user operable lock and a drop-force operable lock are provided to prevent accidental retraction of the guard from the fully extended and guarded position.
