China3D printingNet, June 4, an Israeli anesthesia team recently used3D printingWith virtual reality technology, an accurate model of the respiratory tract of a 7-year-old girl was made as part of the operation to remove her lungs.
Because of bone and soft tissue cancer that had spread to her lungs, the young girl needed to remove part of her right lung.In order to properly prepare for the operation, her doctors at the Suraki Medical Center in Tel Aviv used her airway and lung virtual reality procedures as well as precise3D printingPlastic models so that they can perform surgery in advance.
“Despite our extensive adult surgical experience, our knowledge of pulmonary ventilation (OLV) in the very young pediatric population is still limited,” explained Dr. Ruth Shaylor of the Department of Anesthesiology, Pain and Intensive Care at the Suraki Medical Center in Tel Aviv.
“we will3D printingIt is combined with virtual reality bronchoscopy to develop a personalized surgery plan, thereby reducing manipulation errors during the operation and correct operation of robotic surgery. “

The disease that bothers a young girl has spread to her lungs. It is called Ewing’s sarcoma. This is a rare type of cancer that affects the bones or the tissues around them.
When preparing for the operation on the patient, the doctor’s main consideration was her short stature, because she was only 18 kilograms at the time of the operation. The use of conventional catheters and equipment that are generally suitable for lung surgery in adult patients may cause potential complications.
Therefore, the doctor chose to use CT scans to create virtual reality procedures for her airway/wind duct and lungs. The day before the operation, the attending anesthesiologist spent some time on the virtual reality simulator to familiarize himself with the patient’s airway anatomy.
After that, the model is3D printingAnd used to develop a personalized airway plan. The 3D model is made of hard plastic, because anything softer can be inaccurate, which means that something larger than the patient can withstand can be used.

VR and3D printingThe model means that some of the equipment originally planned for the operation has been changed. Once the girl is anesthetized, they can safely isolate and ventilate the left lung, and perform surgery to remove part of the right lung. “During the operation, the attending anesthesiologist reported that there is a good correlation between the patient’s anatomy and the VR model, and the operation can be performed as planned.” Dr. Shaylor commented, “At the end of the operation, it can be easily pulled out Catheters and equipment, and stabilize the patient’s recovery.”
Dr. Shaylor went on to explain that so far, the3D printingIt is mainly used for educational purposes, but it has the potential to further aid surgery: “In anesthesia3D printingIt is not fully utilized in preoperative planning for specific patients. The same is true for the use of virtual reality in virtual anesthesia. We successfully combined these two technologies to develop a personalized airway plan for pediatric patients. The final airway plan is very different from the plan developed using standard imaging techniques. This reduces the number of lung isolation attempts that would otherwise be performed on the patient. “

Medical services for patients
Many occasions and plans have been established, among which will3D printingUsed for patient-specific preoperative planning to help surgeons perform their procedures.
For example, the Puget Sound Health Care System of Veterans Affairs (VA) announced in 2019 a two-year collaboration with the University of Washington School of Medicine (UW) to create patient-specific3D printingModel to help treat mitral valve disease. Heart abnormalities.
GE Healthcare and Formlabs also announced a collaboration to make it easier for clinicians to extract imaging data3D printingPatient-specific anatomical model.3D printingYes, patient-specific medical equipment has also been used outside of preoperative planning and has been used in the procedure itself. In early 2020, developed by doctors at the Cleveland Clinic3D printingThe patient-specific airway stent has been approved by the FDA and can be implanted in the patient’s body.
