Problems solved by technology
The PHBV and PLA blend braided artificial blood vessel is a kind of artificial blood vessel made of new materials. During the production and processing of the PHBV and PLA blended braided artificial blood vessel, it is necessary to wind the PHBV and PLA blended artificial blood vessel At present, in the winding process, there will be a phenomenon of chaotic, dense and miscellaneous winding, which will reduce the quality of the artificial blood vessel products blended with PHBV and PLA. Based on this, the present invention designs an artificial blood vessel blended with PHBV and PLA. A device for wrapping blood vessels to solve the above problems

The invention discloses a device for winding an artificial blood vessel blended and woven by PHBV and PLA in the technical field of artificial blood vessels, which comprises a base, a lead screw pair, a first positive and negative rotation motor, a pushing mechanism, a winding wheel conveying device, a clamping rotating device, a photoelectric sensor and a cutting mechanism, the winding wheels are connected with the clamping and rotating device one by one through the winding wheel conveying device, the cutting-off mechanism generates a cutting opening in the outer side of a through hole in the side wall of each winding wheel, meanwhile, the pushing mechanism can push one end of an artificial blood vessel into a through hole in the bottom of an inner cavity of each winding wheel, and then the clamping and rotating device moves front and back for a period of time while rotating; and finally, the pushing mechanism is close to a through hole in the side wall of the winding wheel, the winding wheel moves backwards by a certain distance under the action of the clamping and rotating device, the lead screw pair works, the artificial blood vessel is clamped into a shearing opening, and finally the artificial blood vessel is cut off through the cutting mechanism. And creativity is achieved.
Description
technical field [0001] The invention relates to the technical field of artificial blood vessels, in particular to a device for winding artificial blood vessels that are blended and braided by PHBV and PLA. Background technique [0002] The development of artificial blood vessels began in the early 20th century. In the early days, scholars from various countries first used tubes made of metal, glass, silicone rubber and other materials to conduct a large number of animal experiments. widely used. So far, many polymer artificial blood vessels have been used clinically, including polyester, silk, expanded polytetrafluoroethylene, etc. Biomaterials must have good biocompatibility to ensure the safety of clinical applications, but these materials all have biocompatibility problems. Poly-β-hydroxybutyric acid-co-β-hydroxyvaleric acid copolyester (PHBV) has been favored by many researchers at home and abroad due to its excellent biocompatibility and degradability, and the product...
