TRIZ, as a new theory for companies in China, provides both conceptual and procedural knowledge for finding and solving inventive problems. Because the government plays a leading role in the diffusion of TRIZ, too many companies from different industries are waiting to be trained, but the quantity of the trainers mastering TRIZ is incompatible with that requirement. In this context, to improve the training effect, an interactive training model of TRIZ for the mechanical engineers in China is developed and the implementation in the form of training classes is carried out. The training process is divided into 6 phases as follows： selecting engineers, training stage-l, finding problems, training stage-2, finding solutions and summing up. The government, TRIZ institutions and companies to join the programs interact during the process. The government initiates and monitors a project in form of a training class of TRIZ and selects companies to join the programs. Each selected companies choose a few engineers to join the class and supervises the training result. The TRIZ institutions design the training courses and carry out training curriculum. With the beginning of the class, an effective communication channel is established by means of interview, discussion face to face, E-mail, QQ and so on. After two years training practices, the results show that innovative abilities of the engineers to join and pass the final examinations increased distinctly, and most of companies joined the training class have taken congnizance of the power of TRIZ for product innovation. This research proposes an interactive training model of TRIZ for mechanical engineers in China to expedite the knowledge diffusion of TRIZ.展开更多

To facilitate the learning and training of percutaneous renal access and intrarenal procedures under ultrasound and fluoroscopy guidance we reported a biological bench model for percutaneous renal surgery. Methods The model was developed using an ex vivo porcine kidney with a longer than 3 cm ureter, a flap of full thickness of thoracic wall with skin, subcutaneous fascia, muscle and two ribs, as well as the standard equipment for percutaneous nephrolithotomy. The porcine kidney with a catheterized ureter was placed within the porcine flap and fixed to a wooden board with two long steel nails. Afterward, contrast medium or physiological saline （0.9% sodium chloride solution） was injected through the ureter, and the urinary system was examined with a fluoroscopy unit or an ultrasound. Artificial stone material was implanted in the renal pelvis. After practicing, the model could be dissected for kidney examination and a technical analysis. Results The advantage of this model was simple to set up and inexpensive, by using widely available material. The biological bench model can be employed for percutanous renal access, tract dilation, nephroscopy, and stone disintegration in the training and learning of clinical practice. Imaging is feasible under fluoroscopic and ultrasound guidance. The kidney models were utilized in hands on courses with over 100 people, and 90.5% attendants rated the porcine kidney model for simulation of percutaneous renal surgery as ＂very helpful＂ or ＂helpful＂. Conclusion This biological training model simulates realistically the clinical procedure of percutaneous nephrolithotomy under fluoroscopic and ultrasound guidance.展开更多
