Public hospitals are determined to develop "smart hospitals" and introduce more new technologies for medical applications. Elisabeth Hospital used 3D printing technology to develop the "emergency cricothyroidectomy simulation device", assisted doctors in training, and won the silver medal of the "International Invention Award" in Geneva, Switzerland in 2021. In July this year, the hospital set up the first "3D Printing Coordination Office" of the Medical Administration, aiming to print 120 different models within a year, and promote the clinical application of 3D printing technology in public hospitals. The hospital will carry out "cricothyroidotomy" for the patients with airway obstruction and death threat of asphyxia due to lung injury, throat inflammation and other reasons. The operation is required to be fast and accurate. Jia Nanxiong, director of the Comprehensive Simulation and Skills Training Center of Elizabeth Hospital, which set up the "3D Printing Coordination Office", said that in the past, the training of "cricothyroidism" would use pig trachea to imitate human trachea, but they were large and not realistic. The office has developed an "emergency cricothyroidectomy simulation device", which uses 3D printing technology to print a human trachea simulation device to highly restore the human trachea structure, as well as the physiological reaction of the patient during the operation, so that the trained doctors can use the simulation device as if they were rehearsing an operation, successfully improving the quality of clinical high-risk program training, and improving the safety of the operation. Wu Guangrong, director of the medical 3D printing planning office of Elizabeth Hospital, said that since 2015, the hospital has printed more than 120 3D models of organs and tissues, which are used to explain the patient's condition before surgery, simulate surgery, and even tailor assisted living tools. 3D printing technology can print realistic human organ models. Compared with traditional X-ray or computer scanning, it can better plan the operation plan and reduce the time of fixed operations such as heart and kidney by about 20%. (Liu Xinshe)
