The Spark of 3D Printing Technology in the Age of Surgical Robots

The outstanding advantage of 3D printing lies in additive manufacturing. The aided design model is calculated using digital data according to the required shape and size, and then manufactured. Its advantages in rapid prototyping manufacturing of complex structures and the popularization of 3D printing technology reduce its printing cost, and its personalized and refined printing technology allows it to boast unique advantages in the medical field. Especially in the era of robotic surgery, it is expensive to use wet models such as animals for training. Surgeries are of high cost, questionable in terms of ethics and safety, and pathological structures can not be simulated, resulting in extremely low-cost performance. However, 3D printing technology, with its unique advantages (individuation, refinement) and rapid production, just meets the needs of robot surgery training, and its combination with hydrogel has further opened up the future of surgery training. Previous surgical training models used silica gel, but its physical and chemical properties and feedback limitations made it unable to completely simulate surgical scenes. However, hydrogel, a hydrophilic polymer, not only has physiological characteristics similar to biological tissues and organs, but also shows good instrument feedback. In addition, the wet and soft characteristics of hydrogel determine its adaptability to the additive manufacturing method of 3D printing. Personalized, fast and refined 3D printing technology uses hydrogel materials to make highly realistic tissue and organ models and apply them to surgical robot surgery training. In the future, the 3D printing model will replace the previous biological model, change the mode of surgical training, become a new type of surgical training, improve the current situation of surgeon robot surgery training, and occupy the highland!
