The wrist puncture model undoubtedly provides a more efficient, safe and controllable learning environment for clinical interns, significantly improving their learning experience. Through simulation training, interns can not only practice operation skills repeatedly in a risk-free environment, but also greatly strengthen the combination of theory and practice, thus improving the success rate and self-confidence of clinical operation. The experts' views and data analysis show that the simulation model plays an important role in improving the interns' technical accuracy and clinical emergency response ability, and also provides them with a bridge from theoretical knowledge to practical operation. With the continuous development of medical ed
