Zhongshan hospital affiliated to Fudan University is the first full national medical center in China. As a current member of the team in Oto-Rhino-Laryngology at Zhongshan Hospital, Dr. Yu Haran treated a special child. The child was born with complete atresia on both sides and only tiny wells were left. This situation is extremely rare and there is no precedent for successful treatment in the world.
The difficulty of treating this disease is that the appearance of the anterior nostrils of the child and the nasal cartilage have not developed. Even if the operation is open, the surgical cavity will heal quickly due to the lack of support. If we learn from the traditional method of treatment of postnatal atresia and insertion of tracheal intubation or the drainage cannula in the nasal cavity as a support to fix, this will inevitably cause a strong feeling of foreign body in children, the nasal function cannot be carried out normally, the quality of life is bad, the care is difficult and it is easy to provoke a local infection and necrosis.
After discussion with the MDT team of plastic surgery, with the support of the Fuqing Scholar scientific research innovation project “Fudan” Fuqing Scholar “, the team decided to use 3D printing technology to adapt the prototype support model for individualized nostrilles for children. The obvious advantages of 3D printing technology are fully demonstrated in this case:
1. Quick response: 3D printing technology supports the verification of high frequency and fast prototypes, which can meet emergency medical needs.
2. Highly personalized: 3D printing technology can personalize the design as a function of the specific anatomical structure of the patient.
3. Verification of the low -cost prototype: Compared to traditional manufacturing methods, the cost of verifying the 3D printing technology prototype is lower.
4. Special needs during the epidemic: During the epidemic, the conditions of verification of the prototype in hospitals are limited and 3D printing technology provides flexible solutions.
Based on these advantages, Dr. Yu contacted Raishing3D and learned that Raisage3D is developing a whole new 3D DLP – REAGE3D DF2 printer. This is equipment that has completed research and development and production in the country, with stable performance and supports a variety of resin materials.
At the same time, the Raisage3D team has excellent printing service capacities, which can quickly meet and assess customer needs, and provide users with the most appropriate solutions. All parties strike it and decided to use DF2 to prototyper and check the front nostril support mold.
After receiving the request, the Raping3D team made a detailed assessment. Given the comfort of the support and medical compatibility of materials, the team has finally selected theFlexible resin material——AMI Ultracur3D® EL 60 advance for this prototype verification effort.
The entire postoperative support process lasted a year and three months. During this period, the Zhongshan hospital team worked closely with the Raish3d team to determine the changes in the child’s nostrils’ morphology and various use scenarios.Several iterations for the design of support mold have been carried out.
The Ideamaker® self-developed Step Site software of Raishyd ensures the rapid cutting of the model and offers guarantees for smooth printing with its powerful photocurage cutting function and quick singling speed.
Once the edge is completed, the Raisage3D team used a 3D DF2 optical hardening printer to print the support model of support. DF2 adoptsDLP technology，Capable of reaching the printing of high precision, suitable for fine prototyping。
At the same time, the level of professional printing service and the capabilities of the Raing3D team ensures rapid acceptance and the calendar of printing needs and guarantees that each part delivered can meet the needs of users. Thanks to the perfect combination of service capacities and equipment, the Raisage3D team has produced several model design iterations in the same day.
After printing, the model is quickly cleaned and hardened with DF Wash Wash washing and the DF recovery machine. RFID technology automatically transmits the setting parameters throughout the printing, cleaning and hardening process, without manual intervention, further improving efficiency.
Thanks to the complete series of DF2 solutions, the Nothing3D team helped the team at Zhongshan hospital to obtain several fast and low cost iterations to support model prototypes, guaranteeing a timely locking of design solutions.
It is only the tip of the iceberg which lifts 3D fully supports and helps scientific research and innovation in the field of medicine. Technology must not only meet the group’s needs, but also benefit individuals.
This successful case proves once again the enormous potential of 3D printing technology in the medical field – especially in scenarios where time is tight, the structure is complex and highly personalized, 3D printing technology has provided substantial aid to clinicians and patients with its unique advantages of “rapid response + high personalization + tests and errors with low cost”.
Raisage3D will continue to deepen the application of 3D printing in the field of medical research, helping more medical breakthroughs.
