AbstractWe used three-dimensional printing technology to create an anatomical three-dimensional model of a very rare and complex cyanotic CHD in a newborn, consisting of double-outlet left ventricle, ventricular septal defect, and pulmonary stenosis. This case demonstrates how this new innovative technology allows better understanding of the anatomy in complex CHDs and permits to better plan the surgical repair.

Introduction. Images of computed tomography, computed tomography angiography, ultrasonography, magnetic resonance imaging, positron emission tomography are usually stored in Digital Imaging and Communication in Medicine standard formats, which can be used later for processing and making three dimensional models and objects. The three dimensional printing has become increasingly popular in various fields of medicine. The purpose of this article was to present the workflow for three dimensional printing of medical models and to point out potential significance of three dimensional model printing in clinical practice and in training of medical students and residents. This type of approach may open new perspectives in communication and interaction between clinicians, radiologists and patients, in order to achieve better treatment results. Material and Methods. Images of an injured knee in digital imaging and communication in medicine format were used for creation of a three dimensional printed model. Digital imaging and communication in medicine files were without sensitive information on the patient using three dimensional Slicer software, then processed with embodi three dimensional cloud service, further prepared with MeshLab and printed on a Ultimaker 2 printer. Results and Discussion. A three dimensional model of an injured knee was printed and presented. The model was used for the evaluation of tibial fractures. It may be shown to the patient and also to the surgeon in order to be more specific about the treatment procedure. Application of three dimensional printing in medicine was discussed. Conclusion. Medical three dimensional printing is likely to play a more important role in the clinical practice, not only for surgical planning, but also in the education of students and residents in different medical branches. This three dimensional plastic model of an injured knee may serve as a good example of the potentials of the three dimensional printing technology in medicine.

To increase the delivery capacity and flow stability of the screw pump and reduce wear between the stator and the rotor, a surface forming method of single-head cone screw-bush pair with equal cavities and large delivery capacity was investigated based on the conventional single cone screw theory. An equation of the cone screw-bush pair surface was established according to the space engagement theory. A flow equation of single cone screw bush pair was built based on the cone screw-bush pair section equation and the rule of its variation. The calculation method of the screw structure size at a given flow rate was determined as well. A kinematics equation of the single cone screw-bush pair was obtained after a kinematics analysis of the single cone screw-bush pair conducted. The movement formula of a single cone screw-bush pair with equal cavities and large delivery capacity was concluded. Three-dimensional model of a single cone screw and a bush was built and the motion simulation of the pair was conducted based on MATLAB and Pro/Mechanism. The kinematics rules were summarized at the same time. Moreover, a single cone screw and a bush solid model were processed based on the three-dimensional model of the cone screw-bush pair and the three-dimensional printing technology. The correctness of the equation of the single cone screw-bush pair surface was verified.

AbstractIn recent years, three-dimensional printing has demonstrated reliable reproducibility of several organs including hearts with complex congenital cardiac anomalies. This represents the next step in advanced image processing and can be used to plan surgical repair. In this study, we describe three children with complex univentricular hearts and abnormal systemic or pulmonary venous drainage, in whom three-dimensional printed models based on CT data assisted with preoperative planning. For two children, after group discussion and examination of the models, a decision was made not to proceed with surgery. We extend the current clinical experience with three-dimensional printed modelling and discuss the benefits of such models in the setting of managing complex surgical problems in children with univentricular circulation and abnormal systemic or pulmonary venous drainage.
