20100139883 | SURGICAL NEEDLE SWAGE TOOL - In a method of attaching a suture to a needle barrel, a first compression stroke compresses the radially-defined top of the barrel against a suture in the bore of the barrel while restraining the bottom and sides of the barrel against deformation. A second compression stroke compresses the bottom of the barrel against the suture while restraining the sides against deformation. In another method, the top and bottom are compressed concurrently while the sides are restrained against deformation. An apparatus for attaching a suture to a needle barrel includes two die sets, each including a die with a groove therein. In one die set, the groove protects the bottom and sides of the barrel from deformation while the top is compressed. In the other die set, the groove protects the sides of the barrel from deformation while the bottom is compressed. | 06-10-2010 |
20110192562 | STAMPER FOR MICRONEEDLE SHEET, PRODUCTION METHOD THEREOF, AND MICRONEEDLE PRODUCTION METHOD USING STAMPER - Microneedle sheets are produced by injecting a needle raw material into a stamper formed with a concavity in a base material. However, because the stamper concavity is very small, there is the problem that air cannot escape due to air and surface tension of the material, thereby preventing a needle from being formed in part. The present invention provides a stamper for producing a microneedle sheet. The stamper comprises a sheet-like base material including a conical concavity formed from a first surface of the sheet-like base material toward a second surface thereof; and a through-hole formed from a bottom of the concavity toward the second surface. Air can escape via this through-hole, allowing a microneedle sheet which is filled with a needle raw material as far as the bottom of the concavity to be obtained. | 08-11-2011 |
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 |
20120168107 | SURGICAL NEEDLE AND METHOD OF MANUFACTURING A SURGICAL NEEDLE - In order to develop a surgical needle comprising an elongate needle body and a needle point formed on a distal end of the needle body, wherein the needle body is manufactured in particular from an elongate cylindrical blank, in a way that improves the handling ability of the surgical needle, it is proposed that the needle body has at least one textured-profile lateral face, which comprises at least one textured-profile lateral-face region provided with a textured profile, wherein the textured profile comprises a plurality of indentations and wherein the at least one textured-profile lateral-face region extends as far as the needle point. An improved method of manufacturing a surgical needle is also provided. | 07-05-2012 |
