Application of 3D printing guide system in minimally invasive puncture and drainage of cerebral hemorrhage surgery / 中华神经医学杂志

ABSTRACT

Objective To study the design and application of customized navigation module manufactured by digital modeling and 3D-printing technology in the minimal-invasive-puncture surgery for cerebral hemorrhage. Methods Eight patients with cerebral hemorrhage, admitted to our hospital from October 2015 to December 2015 and aged from 33-80 years old (with an average age of 55.7), including 6 male and 2 female, were chosen as study objects. The 3-dimensional image was obtained by three dimensional reconstruction technique. A perfectly personal navigation module included puncturing-guidance-channel was designed and printed by 3D-printing technology. The printing module was tested in surgery. The module was tightly attached to the puncturing area, and the puncturing was performed following the guide system during the surgery. Post-operation cerebral CT scan was performed to evaluate the surgery effect. Results All the 8 patients successfully received surgery. Post-operation cerebral CT scan showed satisfied results which were classified based on accuracy: 6 enjoyed highly accurate results, one qualified result and one acceptable result. The actual puncture direction was the same with that in the pre-operation mimic process. No puncture failure, blood vessel or nervous injury symptoms were found. Conclusion Pre-operation personal 3D printing navigation is an accurate, safe and effective novel method to treat cerebral hematoma.
