소개: 3D 프린팅 기술을 사용하여 인간의 뼈를 대체하는 티타늄 합금 임플란트를 제조하는 중국에는 고관절, 척추, 흉골 등 많은 사례가 있습니다. 그렇다면 인도는 이 측면에서 어떻게 진행되고 있습니까?
2022년 2월 10일, 인도의 Manipal Hospital에서 복잡한 수술을 통해 환자의 암을 성공적으로 제거하고 3D 인쇄된 티타늄 합금을 사용하여 흉골과 갈비뼈를 재건했습니다.{3} 방글라데시에서 온 50세{5}}는 흉골과 왼쪽과 오른쪽에 있는 처음 8개의 갈비뼈에 영향을 미치는 희귀하고 복잡한 암을 앓고 있습니다. 암을 수술로 제거할 수 있다 하더라도 정상적인 호흡에 중요한 흉골과 갈비뼈를 고정할 실행 가능한 솔루션이 없었습니다.
Dr. Somashekhar, Chairman and Chief of Oncology Surgery at Manipal Hospital, said: "Advanced technologies are now available to provide treatment for complex cancer cases that were otherwise considered incurable by many. The credit for this case goes to Manipal Syndrome. The excellent coordination between the cancer center and the plastic surgery department, which has experts in modern technology and medicine, brings hope to millions of cancer patients worldwide."
△The hospital removes the tumor for the patient and implants the 3D printed titanium alloy sternum
특히 복잡한 작업
The patient was taken to Manipal Hospital, where his MRI showed a 15 x 12.7 cm tumor mass over his lungs and heart that had destroyed the length of the patient's sternum and the inside of his ribs. Before surgery, the surgeon performed a CT scan of the patient area, created a personalized 3D model of the desired implant, which was then 3D printed in titanium.
Someshekhar explained, "We 3D printed a new titanium sternum, custom-made for this patient based on his size, height, weight and the part of the bone to be removed, and we worked with the company's technologists, engineers and Manipal Oncology Surgery and The plastic surgery team held several meetings". The patient underwent tumor removal surgery and his entire sternum and ribs were removed without much blood loss. This area was then replaced with a custom-made titanium alloy implant, which was held in place using new drilling techniques and titanium wire. Finally, before the skin is sutured, the implant is covered with a muscle flap removed from the patient's chest to restore normal breathing function.
Someshekhar continued: "The implants are often very heavy, up to 5kg, which is too heavy for the patient to carry on the chest. To correct this, we used a modified honeycomb technique to keep the weight of the sternum and sternum below 250 grams".
완전한 회복
After the operation, the patient recovered smoothly, and after physical therapy of the chest, he was able to move gradually. During his discharge from the hospital, he was reported to be able to eat, breathe and walk normally without any complications. According to Dr. Ashok, Consultant Plastic, Reconstructive and Aesthetic Surgeon at Manipal Hospital, 3D printed implants offer a number of important benefits for patients' recovery.
"The implants are strong, durable and lightweight," he said. In addition, they are well received by the body and are less prone to immune responses and implant rejection. The implants reduce osteoporosis disease, as well as the risk of fracture around the implant due to uneven stress transfer between the implant and surrounding bone tissue". The successful placement of 3D-printed titanium alloy implants means that after the tumor and affected parts of the bone have been removed, the patient no longer has to permanently rely on mechanical ventilation to breathe. "New-age technologies and materials are helping patients with complex problems get resolved and recover quickly," Ashok added.
"This patient is a perfect example of a combination of excellent medical care and technology."
