The present invention relates to a method for manufacturing a nonmagnetic water-cooled microwave ablation needle. The manufacturing method is designed for a microwave ablation needle of a nonmagnetic material and has a proper process procedure, favorable assembly quality, and high production efficiency. The produced nonmagnetic water-cooled microwave ablation needle is applicable to microwave tumor ablation surgery in a nuclear magnetic resonance imaging environment, and helps a doctor in charge to clearly determine a position of a tumor, improve piercing precision, have preferable control on a whole surgery process, improve a success rate of the surgery, reduce damage on surrounding normal tissues as much as possible on the premise of effectively inactivating the tumor, alleviate pain of a patient, and shorten a recovery cycle.

An in-plane metal microneedle array and a manufacturing method therefor is disclosed. A large-size metal sheet is cut into small metal sheets. Inner sides of the upper and the lower cover plates of the tooling are provided with grooves matched with the sizes of the small metal sheets. Through holes are formed at edges around the cover plates. The metal sheets are placed in the grooves and fastened through bolts. The geometry and the size of a sheet microneedle array are designed, and a CAD model of the plane microneedles is built. A wire path is cut according to the CAD model. A few materials are reserved on both sides of substrates of the microneedle array without cutting. The unprocessed parts on both sides of the microneedle substrate are cut to obtain an in-plane metal microneedle array with a plurality of microneedle bodies.

A metallic knitting needle is disclosed that includes a knitting needle tip and a holding shaft. The knitting needle tip is used to entwine stitches. The holding shaft extends from the knitting needle tip in a shaft longitudinal direction. The holding shaft also has at least three gripping surfaces for holding the knitting needle. The gripping surfaces each have a plurality of elevations distributed in the longitudinal direction. Each two adjacent gripping surfaces are connected by a rounded transition region.

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 is made of austenite stainless steel having a structure that is elongated in fiber form, and has a cutting portion and a body portion with a triangular cross-sectional shape that is continuous with said cutting portion. The cutting portion has cutting edges, at least one surface of which is formed by a pressed surface, and which are formed by the intersection of said pressed surface with two sharpened surfaces, and a cutting edge that is formed by the intersection of the two sharpened surfaces. The tip where the various cutting edges and converge is positioned in the center of the pressed surface. Moreover, the cutting edges formed by the intersection of the above pressed surface with the two sharpened surfaces are longer than the cutting edge that is formed by the intersection of the two sharpened surfaces.

The tool (10) for textiles according to the invention consists of chromium steel, into which carbon has been embedded in locally varying amounts during a carbonizing process. Thermal treatment achieves a formation of martensite with the maximum achievable hardness, in particular in those zones in which larger carbon fractions have been introduced. A tool for textiles with zones of differing hardnesses can thus be produced without having to subject the individual zones with differing hardnesses to different process conditions during the production process. The hardness is controlled on the basis of the degree of deformation of the tool for textiles.
