Embodiment 2
[0034] The difference from Example 1 is that the floating ring is pretreated before use, and the pretreatment method is: the floating ring is drilled with a laser, and the inside of the floating ring is filled with medical stone particles until the floating ring cavity Fill the body, and wrap a layer of polytetrafluoroethylene fiber mesh on the inner and outer rings of the floating ring; then immerse the floating ring in the nutrient colloid for 4 minutes, remove and drain, and immerse in the sealing film colloid solution for 5 seconds. After the film is solidified, put the floating ring into the nutrient colloid for 2 minutes, remove and drain, immerse in the sealing film colloid solution for 10 seconds, remove and solidify; the hole diameter is 4mm, and the hole density is 5 / 10cm 2 The medical stone particle size is 3cm; the mesh aperture of the polytetrafluoroethylene fiber net is 1.5cm; the preparation method of the nutritional colloid is: in parts by mass, 15 parts of silk...
