20130197549 | EDGED MEDICAL CUTTING TOOL - [Problem] To provide a medical cutting tool with low impalement resistance. [Solution] The edged medical cutting tool comprising a knife, trocar or cutting suture needle has a sharp edge ( | 08-01-2013 |
20130172917 | MEDICAL KNIFE - [Problem] Because the knife edge of medical knives such as straight knives manufactured with austenite stainless steel is thin and sharp, there is the problem that the knife edge bends too easily when making incisions in the cornea, sclera, etc. during ophthalmologic surgery. The invention provides a medical knife capable of increasing the strength of the thin, sharp knife edge and preventing the reduction of sharpness. [Solution] This medical knife has a flat cutting part and an inclined surface formed along the border of said cutting part. By electrolytic polishing or chemical polishing of the inclined surface, a convexly curved cutting edge is formed on at least the edge of the inclined surface of the knife. The knife edge has a rounded configuration. The knife edge being rounded increases the thickness of the knife edge, increases the strength thereof and hinders bending. | 07-04-2013 |
20130045460 | STAINLESS STEEL BUR - A stainless steel bur is provided which can cut minute depressions and even healthy dentin when necessary, allowing a technician to detect when cutting the healthy dentin. A handle connected to a hand piece on the base side, a working section to which a cutting blade for cutting teeth is attached to the tip, and the working section and the handle are connected to a tapered intermediate section. This steel bur is formed into a fiber structure by hardening austenitic stainless steel. Since the tapered part bends and generates vibrations when the working section is rotated to cut healthy dentin, it can be understood that the healthy dentin is being cut, and excessive cutting may be prevented. Alternatively, excessive cutting may be prevented by processing from the maximum diameter of the working section to the tip thereof through etching to round cutting blade edge and make a blunt edge. | 02-21-2013 |

20110144676 | Medical Bladed Device And Method For Coating Medical Bladed Device - Provided is a medical bladed device reduced in piercing resistance by coating with a silicone. Also provided is a coating method by which a satisfactory silicone coating is formed on a medical bladed device. A medical bladed device (knife (A)) having a cutting portion ( | 06-16-2011 |
20110112575 | Medical Suture Needle - The goal is to provide a medical suture needle having, as the material, austenite stainless steel with a structure that is elongated in a fiber form while improving the hardness and flexural strength of the cutting portion. A medical suture needle (A) is made of austenite stainless steel having a structure that is elongated in fiber form, and has a cutting portion ( | 05-12-2011 |
20110030435 | Bending Method And Bending Apparatus For Medical Suturing Needle - Provided are a bending method and a bending apparatus for bending a medical suturing needle into different curved shapes by using one bending top. The bending apparatus comprises a reciprocally rotatable bending top, and a belt having such a flexibility as can be wound on the outer circumference of the bending top. The bending method curves a medical suturing needle by sandwiching and constricting a material for the medical suturing needle between the bending top and the belt and by rotating the bending top reciprocally in the winding direction and in the rewinding direction. In the bending method, the curved shape of the material is changed by changing the winding angle of the belt to be wound on the outer circumference of the bending top thereby to change the area for constricting the material. The bending apparatus (B) comprises a reciprocally rotatable bending top ( | 02-10-2011 |
20110029015 | Medical Staple And Magazine - There are provided a medical staple realizing smooth feeding when loaded in a magazine and a magazine which can realize stable feeding by using the medical staple. | 02-03-2011 |

20090117831 | Method Of Manufacturing Treatment Device And Treatment Device - A tapered cutting edge portion and a continuous raised portion from the tapered cutting edge portion are ground in an edge portion of a straight grinding raw material so that an eccentricity is not generated. In a method for grinding a treatment device, one end portion of a tapered grinding raw material is inserted between a grinding surface of a grindstone and a pressing surface of a press block, and finishing surfaces opposite each other while having a predetermined dimension, shape, and angle are ground so that a direction in which abrasive grains of the grindstone run corresponds to a direction of a shaft center. At this point, before the finishing surfaces are ground in the predetermined dimension, shape, and angle which are previously set corresponding to an objective reamer, pre-grinding is performed while a necessary finishing margin with respect to at least one of the surfaces, and then finishing grinding is performed to the other surface. | 05-07-2009 |
20090039117 | Eyeless Sewing Needle and Fabrication Method for the Same - In an eyeless sewing needle, a periphery of an axial hole at the base end is heated to make a fibrous structure be a granular structure without directionality, and at least a part of a heat-affected zone made between the fibrous structure and the granular structure due to the heating is within a range that is three times the diameter of the sewing needle and that extends from an effective base of the axial hole towards the needlepoint. This allows provision of a flexible sewing needle so that the hole periphery can be processed while keeping a hard state at the position of the needlepoint slightly away from the axial hole. | 02-12-2009 |
