The First Affiliated Hospital of Kunming Medical University is a large-scale general hospital integrating medical treatment, teaching, scientific research, and cadre health care. The hospital was built in 1941 and was originally named as \u201cThe affiliated Hospital of National Yunnan University School of University\u201d (i.e. Yunda Hospital). In 1993, it was appraised by the Ministry of Heath as the first batch of \u201cTier-A hospitals\u201d. At present. The number of beds in the hospital is 4000 (including 1000 in Chenggong) with 57 clinical and medical technical departments. There are 5 national key specialties, 24 provincial key clinical specialties, 16 provincial quality control centres, 30 internal research laboratories (8 research institutes), and 217 prefectures (Cities) and countries in Yunnan Province. The hospital has established a medical strategic alliance;<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

On July 3, 2018. Shi Yunfei, director of the Department of Thoracic Surgery of the First Affiliated Hospital of Kunming Medical University used a high-temperature 3D printer MAGIC-HT-L from IEMAI 3D to perform a 3D printed clavicle replacement operation. According to verification, this is the world\u2019s first use of 3D printing technology to print the PEEK prothesis for collarbone replacement. The operation also solves other complicated problems of patients who also have multiple lesions, including vessel replacement, tumour resection, clavicle replacement and other types of operations.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

3D printed PEEK implants have the advantages of individualization, precision, and closeness to autologous bone. There will be no barriers to metal materials in the later treatment of cancer patients, and it will not affect the patient\u2019s CT and NMR, which is helpful for the patient\u2019s chemotherapy afterwards and etcetera.<\/p>\n

PEEK material was selected for the first operation. After repeated research by the combine work from doctors and engineers; with the help of CAD Software for modification, after many times of revisions and demonstration, the guide plate and clavicle model were finally finalized.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The patient was 57 years old and male. The cancer cells spread to the veins near the right subclavian and invaded the first rib. The clavicle had to be cut off before the vein resection under the clavicle could be perform. If traditional method is used, which titanium mesh was simply used to secure and fix after cutting the clavicle, it will affect the patient\u2019s late treatment. After 2 weeks of preparation, on July 3, the patient underwent this whole series of operation of partial right clavicle resection, partial right first rib resection, subclavian vein resection, artificial blood vessel replacement, right upper lung cancer resection and ten mediastinal lymph node dissection under general anesthesia, and 3D printed artificial clavicle replacement. This resection was complete, the patient was in good condition before the operation and the process was smooth and result accurate. The patient recovered well after the operation.<\/figure><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

PEEK (polyetheretherketone) is a special polymer material with excellent properties such as safety stability, high temperature resistance, self-lubricating, easy processing, high mechanical strength and low dissolution. It can withstand repeated autoclaving and has been used several times in the field of medical. PEEK has an excellent compatibility with the human body, and its elastic modulus is similar to human bone. As an artificial bone material, it has gradually replaced the traditional titanium metal and is currently a good choice for substitution of bone.<\/p>\n

Through 3D printing, a highly personalized, precise and customized prothesis is realized which brings a completely new treatment methods to patients and doctors. With the development of science and technology, it will play a revolutionary role in the clinical medicine. The role of IEMAI 3D high temperature 3D printer MAGIC-HT-L can achieve a layer resolution of 0.05 mm, position accuracy X\/Y: 12.5\u03bcm and Z: 1.25\u03bcm. The machine is easy to maintain, PEEK material also meets the requirements of medical use, thus the First Affiliated Hospital of Kunming Medical University selects the machine and materials for clinical use.<\/p>\n
