With the development of science and technology, there are constantly new technologies used in medicine, and related medical technologies have also been greatly improved. Anatomy is one of them. This technology has been widely used in clinical practice, but traditional anatomy is evaluated before surgery. There shortcomings, and it is impossible to have a more accurate understanding of the disease. Therefore, improper operation may still cause some problems during the operation, such as bile duct and blood vessel damage, organ failure and other adverse consequences. Duodenum and its surrounding organs are a complex surgical method. Based on the characteristics of the site, it involves multiple organs such as the pancreas, duodenum, and bile ducts. The anatomical structure of the organism is destroyed, and the destroyed structure is artificially constructed to create a highly difficult surgical technique for new physiological channels. With the development of medicine, the application of three-dimensional visualization technology in this operation can accurately measure the pathology of the duodenum and its surrounding organs, and make preoperative planning and planning for the excision of the duodenum and its surrounding organs. The success of the operation plays an important role. This article mainly analyzes the current situation of the anatomy of the duodenum and its surrounding organs under the background of current medical technology, and proposes an idea on how to optimize and enhance the anatomy of the duodenum and its surrounding organs. Series recommendations. And try to find a new way out for the anatomy of the duodenum and its surrounding organs in the current era based on the results of these studies. Experimental research shows that the use of three-dimensional technology can greatly improve the anatomy of the duodenum and its surrounding organs. The use of this technology, combined with the doctor's solid foundation, can greatly improve the success rate of the operation.

Post-traumatic limb deformity is often multiplanar and thus is a difficult pathology to deal with surgically. Precise preoperative planning and accurate intraoperative execution are two main important steps that lead to satisfactory outcome. Computer-assisted planning and three-dimensional-printed patient-specific instrumental guides provide excellent aid to the two steps, respectively. We report a case of posttraumatic lower limb deformity in a patient who underwent closing wedge corrective osteotomy with the aid of the aforementioned new technologies.

Three-Dimensional (3D) printing is an emerging medical technology with capacity to revolutionize multitude aspects of clinical care and medical education. This commentary highlights The Ottawa Hospital Medical 3D Printing Program, a leading Canadian site for the manufacturing of 3D-printed clinical solutions. In Ottawa, 3D printing has already been employed to optimize preoperative surgical planning, facilitate communication with patients, and enhance medical learning and outreach efforts. Rapid advances in manufacturing technology are poised to further expand current medical applications of 3D printing nation-wide.

Recent advances in additive manufacturing, specifically direct ink writing (DIW) and ink-jetting, have enabled the production of elastomeric silicone parts with deterministic control over the structure, shape, and mechanical properties. These new technologies offer rapid prototyping advantages and find applications in various fields, including biomedical devices, prosthetics, metamaterials, and soft robotics. Stereolithography (SLA) is a complementary approach with the ability to print with finer features and potentially higher throughput. However, all high-performance silicone elastomers are composites of polysiloxane networks reinforced with particulate filler, and consequently, silicone resins tend to have high viscosities (gel- or paste-like), which complicates or completely inhibits the layer-by-layer recoating process central to most SLA technologies. Herein, the design and build of a digital light projection SLA printer suitable for handling high-viscosity resins is demonstrated. Further, a series of UV-curable silicone resins with thiol-ene crosslinking and reinforced by a combination of fumed silica and MQ resins are also described. The resulting silicone elastomers are shown to have tunable mechanical properties, with 100–350% elongation and ultimate tensile strength from 1 to 2.5 MPa. Three-dimensional printed features of 0.4 mm were achieved, and complexity is demonstrated by octet-truss lattices that display negative stiffness.

Abstract Aims Increased complexity in cardiac surgery over the last decades necessitates more precise preoperative planning to minimize operating time, to limit the risk of complications during surgery and to aim for the best possible patient outcome. Novel, more realistic, and more immersive techniques, such as three-dimensional (3D) virtual reality (VR) could potentially contribute to the preoperative planning phase. This study shows our initial experience on the implementation of immersive VR technology as a complementary research-based imaging tool for preoperative planning in cardiothoracic surgery. In addition, essentials to set up and implement a VR platform are described. Methods Six patients who underwent cardiac surgery at the Erasmus Medical Center, Rotterdam, The Netherlands, between March 2020 and August 2020, were included, based on request by the surgeon and availability of computed tomography images. After 3D VR rendering and 3D segmentation of specific structures, the reconstruction was analysed via a head mount display. All participating surgeons (n = 5) filled out a questionnaire to evaluate the use of VR as preoperative planning tool for surgery. Conclusion Our study demonstrates that immersive 3D VR visualization of anatomy might be beneficial as a supplementary preoperative planning tool for cardiothoracic surgery, and further research on this topic may be considered to implement this innovative tool in daily clinical practice. Lay summary Over the past decades, surgery on the heart and vessels is becoming more and more complex, necessitating more precise and accurate preoperative planning. Nowadays, operative planning is feasible on flat, two-dimensional computer screens, however, requiring a lot of spatial and three-dimensional (3D) thinking of the surgeon. Since immersive 3D virtual reality (VR) is an upcoming imaging technique with promising results in other fields of surgery, we aimed in this study to explore the additional value of this technique in heart surgery. Our surgeons planned six different heart operations by visualizing computed tomography scans with a dedicated VR headset, enabling them to visualize the patient’s anatomy in an immersive and 3D environment. The outcomes of this preliminary study are positive, with a much more reality-like simulation for the surgeon. In such, VR could potentially be beneficial as a preoperative planning tool for complex heart surgery.

The integration of Artificial Intelligence technology and school education had become a future trend, and became an important driving force for the development of education. With the advent of the era of big data, although the relationship between students’ learning status data was closer to nonlinear relationship, combined with the application analysis of artificial intelligence technology, it could be found that students’ living habits were closely related to their academic performance. In this paper, through the investigation and analysis of the living habits and learning conditions of more than 2000 students in the past 10 grades in Information College of Institute of Disaster Prevention, we used the hierarchical clustering algorithm to classify the nearly 180000 records collected, and used the big data visualization technology of Echarts + iView + GIS and the JavaScript development method to dynamically display the students’ life track and learning information based on the map, then apply Three Dimensional ArcGIS for JS API technology showed the network infrastructure of the campus. Finally, a training model was established based on the historical learning achievements, life trajectory, graduates’ salary, school infrastructure and other information combined with the artificial intelligence Back Propagation neural network algorithm. Through the analysis of the training resulted, it was found that the students’ academic performance was related to the reasonable laboratory study time, dormitory stay time, physical exercise time and social entertainment time. Finally, the system could intelligently predict students’ academic performance and give reasonable suggestions according to the established prediction model. The realization of this project could provide technical support for university educators.
