Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figure 1 to Figure 3 As shown, an embodiment of the three-phase tissue engineering scaffold of the present invention includes a bone scaffold 1, a cartilage scaffold 2 and a tendon scaffold 3 stacked and integrated sequentially from top to bottom, and one end of the bone scaffold 1 is set as a bone fixation cladding part 11. The other end of the bone bracket 1 is cut transversely and provided with a plurality of bone leaf sheets 12 extending to the bone fixation wrapping part 11, and a bone differentiation cell sheet 13 is arranged between each bone leaf sheet 12; one end of the cartilage bracket 2 Set as the cartilage-fixed wrapping portion 21, the other end of the cartilage support 2 is cut transversely and provided with a plurality of cartilage-like leaf sheets 22 extending to the cartilage-fixed wrapping portion 21, a...
