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 |
20090292312 | TRIANGULAR SUTURE NEEDLE - A triangular suture needle having a low thrust resistance and a press mold suitable for manufacturing the same are provided. The triangular suture needle includes: an angular triangular prism-shaped part ( | 11-26-2009 |
20100023053 | EYELESS SUTURE NEEDLE AND METHOD OF MANUFACTURING THE SAME - A simple fabrication method for a suture needle coated with silicone, which prevents silicone from penetrating into a hole is provided. | 01-28-2010 |
20100069956 | Bending Method Of Medical Suture Needle And Medical Suture Needle - When a biotissue is sutured using a curved medical suture needle, the penetration resistance becomes uniform. | 03-18-2010 |
20100092919 | DENTAL GRINDING BAR AND PROCESS FOR MANUFACTURING THE SAME - The present invention provides a dental grinding bur with a coating material on an identification part that does not peel off easily and does not require formation of a groove in order to apply the coating material on the identification part. It includes a rod-shaped base | 04-15-2010 |
20100263425 | Bending Method Of Medical Suturing Needle - There is provided a method of bending a medical suturing needle curved at different curvature radii in a length direction more reasonably. | 10-21-2010 |
20110200964 | STAINLESS STEEL BUR - A stainless steel bur, which can cut minute depressions etc. and even healthy dentin when necessary, allowing a technician to detect when cutting the healthy dentin is provided. It includes a removable handle ( | 08-18-2011 |
20110315334 | HOLE OPENING DEVICE AND HOLE OPENING METHOD FOR EYELESS NEEDLE - There is provided a hole opening device and a hold opening method for an eyeless needle capable of accurately aligning the center of a needle material and the optical axis of a laser beam as well as opening a hole precisely even with a thin needle material. A plurality of needle materials | 12-29-2011 |
20120123470 | Medical Suturing Needle - Provided is a medical suturing needle or a round needle having a circular section, which is balanced between the magnitude of an insertion resistance to living tissues and the difficulty in damaging gloves, thereby to improve the safety. The medical suturing needle (A) comprises a ball-shaped needle tip ( | 05-17-2012 |
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 |

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 |
20100023054 | Suturing Needle - Provided is a suturing needle, which can be reliably held by a needle holder, which can transmit a high thrust, and which can reduce the fear of damaging a patient and the deformation when a strong force acts. The suturing needle has a representative constitution including a needle tip portion ( | 01-28-2010 |
20100032101 | Caulking Device - [Problems] To prevent a shearing force from acting on a suture thread when it is inserted into a stop hole formed in the proximal end face of a medical suture needle and caulked. | 02-11-2010 |
