Bionic materials have wide application potential, but development of a simple and universal method for manufacturing muscle simulation high-performance protein materials with anisotropic characteristics is still a challenge. The invention provides a strategy of protein arrangement driven by fast photochemistry combined with directional airflow, and protein molecules are arranged along the airflow direction in the hydrogel drying process. Similar to natural muscles, the mechanical properties of the materials can be further improved through mechanical training. This manufacturing process is compatible with conventional printing techniques, making it possible to create complex structures with controllable anisotropy and customized mechanical properties. The anisotropic protein materials show bionic rapid actuation and adaptability under complex physiological conditions, and the potential of the anisotropic protein materials as a vascular dilator is proved through concept verification application. According to the directional airflow driving method and the high-performance protein material produced by the directional airflow driving method, a bionic technology with a prospect is provided for the wide field from medical instruments to self-adaptive materials.

The invention discloses an internal arteriovenous fistula vascular dilator which comprises a telescopic band, a first pressure measuring knob, two sliding grooves, two fixing assemblies, a second pressure measuring knob, a third pressure measuring knob and three pressure gages. Connecting structures matched with each other are arranged at the two ends of the telescopic band and used for surrounding and fixing the telescopic band to the arms of the patient, and the tightness of the telescopic band is changed by adjusting the connecting positions of the connecting structures so as to adapt to the thicknesses of the arms of different patients. Therefore, the three pressure measuring knobs with the pressure gauges are arranged, the pressure can be accurately regulated and controlled, the blood vessel pressing accuracy is improved, blood vessel dilation is promoted, other vein blood vessels can be prevented from being pressed, complications are reduced, meanwhile, the fixing assemblies can slide in the sliding grooves, the related knobs are driven to flexibly adjust the positions, accurate adjustment can be achieved according to the blood vessel position difference of a patient, and the operation is convenient. And the universality and the applicability are improved.

A dilator lumen extends from a proximal end of the blood vessel dilator through the elongated tube and the dilator tip to a distal end of the blood vessel dilator. A rigid section of the blood vessel dilator is formed by the distal end of the elongated tube and a proximal end of the dilator tip, the rigid section having a bending stiffness that is higher than an average bending stiffness outside of the rigid section of the blood vessel dilator.

This utility model discloses a novel vascular dilator, comprising an instrument rod, a balloon, an inner tube, and a stent. The stent is fitted over the balloon. One end of the inner tube passes through the instrument rod and communicates with the balloon, while the other end of the inner tube passes through the instrument rod and has a pump connection port. The side of the balloon facing away from the pump connection port is designated as the front section of the balloon. The stent is detachably fitted onto the outer wall of the front section of the balloon. The rear section of the balloon protrudes from the stent. A drug coating is applied to the outer wall of the rear section of the balloon. Opaque marking layers are provided on the outer wall of the balloon on the side of the stent facing away from the drug coating, at the connection point between the stent and the drug coating, and on the side of the drug coating facing away from the stent. The stent and the drug coating are simultaneously separated by these marking layers. This novel vascular dilator, through balloon expansion, simultaneously releases the distal stent and the proximal drug coating, simplifying the surgical procedure, shortening the surgical time, reducing radiation exposure for both patients and medical staff, and decreasing medical expenses.
