The best treatment for tracheal stenosis or tracheal tumors is a segmental tracheal resection. However, trachelectomy is extremely difficult and risky. As a result, patients with severe conditions often travel to major hospitals across the country without finding an attending physician, and end up suffocating and dying. Tracheotomy is difficult and carries a lot of risks. The most difficult part is that the length of tracheal resection is difficult to determine accurately before surgery, and often the extent of the lesion is found to be more extensive than estimated before surgery, so a longer trachea needs to be removed. The human trachea is only 10 to 11 centimeters long, and it is difficult to anastomose by removing 4 to 6 centimeters. If the severed trachea could not be connected on the operating table, it would be the biggest disaster for the surgeon and the patient, how to get off the table? As a result, the patient would inevitably die. Therefore, tracheal surgery makes doctors look for danger and discourage them. Tracheal transplantation and the traditional concept of artificial trachea (including tissue engineering artificial trachea) are not really applied to the clinic due to rejection, inability to solve the blood supply, no tracheal mucosal re-cap, etc. It can be said that the artificial trachea so far, whether made of carbon fiber, silicone or other materials, is at best an internal stent that cannot form a biological healing with the human trachea. Zhao’s artificial trachea is a real artificial trachea invented by us after years of animal experiments, breaking the traditional concept and combining with modern material technology, which can achieve the purpose of biological healing with the patient’s own trachea and truly become an organic part of the patient’s own trachea. The scientific name of this device is “memory alloy mesh stage-shaped artificial trachea”. The principle is that a pre-formed (rectangular) memory alloy mesh is buried under the skin in the first stage of surgery, and then after the skin and deep tissue have completely healed, a second surgery is performed to cut along the edge of the mesh, and then the skin is rolled up on the inner surface and sutured into a tube with an outer layer of connective tissue and muscle vascular tissues to ensure blood supply. It was then placed between the upper and lower ends of the severed trachea and anastomosed with the upper and lower ends of the trachea respectively. The skin on the inner surface is healed with the mucosa of the trachea, so that the artificial trachea is completely isolated from the outside world and the artificial material is completely enclosed in a sterile environment to ensure the biological healing of the artificial trachea and its own trachea. This is the key to distinguish it from all artificial tracheas in the world and is a real artificial trachea. It has been called Zhao’s artificial trachea in domestic and international literature. With this technology, we have a way to connect the severed trachea even if the tracheotomy is longer, so we can treat all kinds of patients. In mild cases, tracheoscopic laser cryotherapy, dilatation therapy, surgery in severe cases, and stenting in untreatable patients, ensuring that all patients have a most suitable treatment method and achieve the best treatment results.
