23 Jul Composite electrospinning device for manufacturing three-dimensional micro-nano conductive tissue engineering scaffold
Abstract
The invention discloses a composite electrospinning device for manufacturing a three-dimensional micro-nano conductive tissue engineering scaffold. The composite electrospinning device comprises a portal frame, a near-field electrospinning nozzle, a far-field electrospinning nozzle, a near-field high-voltage power supply device, a far-field high-voltage power supply device and a collection vessel. A near-field X-axis motion platform and a far-field X-axis motion platform are arranged on the portal frame. A near-field Z-axis motion platform is arranged on the near-field X-axis motion platform. The near-field electrospinning nozzle is arranged on the near-field Z-axis motion platform. A far-field Z-axis motion platform is arranged on the far-field X-axis motion platform. The far-field electrospinning nozzle is arranged on the far-field Z-axis motion platform. A Y-axis motion platform is arranged below the portal frame. The collection vessel is arranged on the Y-axis motion platform. The near-field high-voltage power supply device can form an electric field between the near-field electrospinning nozzle and the collection vessel. The far-field high-voltage power supply device can form an electric field between the far-field electrospinning nozzle and the collection vessel. The composite electrospinning device is used for manufacturing the three-dimensional biological scaffold with conductivity, an extremely small fiber diameter, uniform wire diameter distribution, orderly fiber distribution and large enough thickness.
