摘要The practice of artificial tracheal prosthesis has been a major challenge to the entire surgical field worldwide until now.The previously applied prosthesis is "inner stent" type,which is unable to heal biologically with native trachea.[1] The newly developed design, the Zhao's artificial trachea, uses a memory alloy mesh combined with traditional operation procedures.Following a 2-year experimental period, the device has been applied to seven patients with satisfying results.We believe this to be a successful artificial trachea that is capable of complete biologically healing with the native trachea.No rejection, infection, or major complications were present in the seven patients, and the Zhao's artificial trachea may be considered a real part of the trachea.
