What kind of sparks will 3D printing and medical care shine? The day before yesterday, the Sixth National Digital Medicine Academic Conference of the Chinese Medical Association held in Nanjing attracted more than 1,000 experts from 28 countries and regions. 3D simulation of tumors, custom bones, etc. have been implemented in our city.
At the conference, the reporter saw the magic of 3D printing in the clinical community.
The tumors that grow freely are often "unclear" with many surrounding tissues and organs. If there are dangerous blood vessels around them, many doctors dare not easily approve the patients' surgery.
"In the past complicated surgery, the doctor mainly relied on the patient's CT and MRI images. Because it is only a planarized two-dimensional image, doctors need to rely on their own imagination to construct the three-dimensional space of organs and tumors to discuss several sets of surgical plans, and move the knife in the operating room. Open the chest or abdominal cavity to choose the best surgical plan.†Professor Wang Liming, director of the Institute of Digital Medicine of Nanfang University and director of the Department of Orthopaedics of Nanjing First Hospital, told reporters that nowadays, with 3D printing technology, tumors and organs can be completely “clonedâ€. Tumors can be described as "live" in front of doctors and patients.
He introduced that the location, shape, size and adjacent relationship with the surrounding tissue can be seen at a glance. The doctor can simulate the operation on the model first, so that the actual operation will be very accurate, and the operation time will be greatly shortened, and the wound area will be small.
Customizable "bone" can be directly implanted into patients
In real life, some tumors will affect the patient's life after resection. The patient may not have the opportunity to walk like a normal person, but 3D technology can also be used to customize the human bones to make up for the patient's regret.
Ms. Li, 52, was diagnosed with osteosarcoma of the femur at the beginning of this year. "In the past, the patient's tumor was cut off 2/3 when the tumor was removed, and then bones or volunteers donated from themselves were donated. The bones." Wang Liming said that taking bones from oneself is often "removing the east wall and making up the western wall." After all, human bones are limited, and many cannot be replaced by their own bones. With the bones donated by the volunteers, there is a great risk of rejection. Therefore, many operations take direct amputation, and disability is a reluctance for many patients to face.
