Embodiment Construction

[0009] according to figure 1 As shown, the present invention is further described: two kinds of raw materials of polyester low elastic yarn and polyester coated spandex are simultaneously fed into 28E double needle bed automatic flat machine (1) for weaving, and the two materials are first twisted together to form a wire for weaving, A part is pulled out to form a jacquard terry loop (2), and the formed jacquard terry loop (2) is put on another jacquard terry loop (2), and weaved sequentially, and finally the knitted fabric forms a tubular knitted fabric with a lower density 28 mesh / half inch. Take the braided blood vessel off the flat knitting machine, cut it into a semi-finished product with a length of 30 cm, then fix the semi-finished product on the spiral rod for shaping, and then determine the shaping mold according to the different diameters of the braided fabric according to the number of needles, such as : 28 pins corresponding to caliber 24 mm. Then the finalized p...

Abstract

The invention discloses a method for weaving artificial blood vessels with high output, stable quality and good quality. The steps include: stacking two raw materials of polyester low elastic yarn and polyester coated ammonia on a 28E needle bed automatic flat knitting machine (1) For weaving, the double-needle-bed automatic flat knitting machine first twists two kinds of raw materials into a thread, and then pulls out a part of the thread to form a jacquard terry loop (2), and sets the jacquard terry loop (2) on the previous jacquard terry loop (2). on the coil (2), and finally weave the raw material into a tubular fabric, and then use different shaping dies according to different calibers. The shaping dies are copper spiral rods with diameters of: 6, 8, 10, 12, 16, 18, 20, 22, 24 millimeters, put the tubular fabric on the outside of the mold and fix it with a thin thread, and put it into a high-temperature and high-pressure steam sizing device for shaping, so that the tubular fabric will be made into a spiral artificial blood vessel.

Description

technical field [0001] The invention relates to the field of medical artificial organs, in particular to a method for weaving artificial blood vessels. Background technique [0002] Artificial blood vessels are widely used in the field of surgery. Artificial blood vessels are used to replace autologous diseased blood vessels, or to be implanted as bypass vessels when autologous blood vessels are blocked, or to establish new vascular pathways in vascular reconstruction. In the 1950s, seamless artificial blood vessels were successfully developed and began to be used clinically. The requirements for artificial blood vessels are: stable physical and chemical properties; appropriate mesh size; certain strength; good sutureability during implantation operations; When the blood vessel is connected, there is no bleeding or less bleeding and it can stop immediately; after transplanting into the human body, the tissue reaction is slight, and the human tissue can quickly form a new inn...
