Photo-cured hydrogel conveying device for minimally invasive surgery and in-situ printing method

The invention discloses a photo-cured hydrogel conveying device for minimally invasive surgery and an in-situ printing method. The device comprises a shell, a rotary steering structure and a coaxial spraying nozzle, wherein the rotary steering structure and the coaxial spraying nozzle are installed in the shell, the coaxial spraying nozzle is installed in the shell, and the outlet of the coaxial spraying nozzle is located outside. The posture is changed and adjusted through the transmission of an internal bevel gear group, the rotation of a handle around the Y axis is converted into the rotation of the coaxial spraying nozzle around the X axis, and the rotating range of the coaxial spraying nozzle is 0-180 degrees. The posture is indicated by scale lines on the outer handle, the rotating angle of the handle is indicated by the outer circle, and the rotating angle of the coaxial spraying nozzle at the tail end is indicated by the inner circle. The coaxial spraying nozzle is in a round tube shape. The outlet of the coaxial spraying nozzle is located on the longitudinal axis of a round tube. An embedded curing light source is adopted for one part of the coaxial spraying nozzle. The outer circle of the coaxial spraying nozzle has a material outlet effect and a light shielding effect. Illumination light sources are evenly distributed on the periphery of the coaxial spraying nozzle.By means of the continuous illumination and interval feeding segmented curing strategy, the material curing uniformity is ensured, and efficiency is improved.
