Demonstration of the training model steps for vasectomy

The demonstration of the training model steps for vas deferens ligation is mainly used to standardize trainees' mastery of the surgical process in a risk-free environment. Before the operation, trainees need to clean their hands, wear sterile gloves, and prepare surgical instruments and dressings.

First, place the model in an appropriate position, perform local disinfection of the scrotal skin and cover it with a sterile cloth. Subsequently, the vas deferens was located by palpation, the incision point was selected, and a small incision was made on the scrotal skin with a knife.

The second step is to separate the subcutaneous tissue through an incision, expose and clamp the vas deferens, and then lift it with tweezers.

The third step is to separate and cut the vas deferens, remove part of the middle section, and use ligation or electrocoagulation to seal both ends to ensure the sperm passage is blocked.

The fourth step is to carefully check for any bleeding. After confirming that the bleeding has stopped well, place the vas deferens back into the scrotum.

Finally, suture the incision, apply sterile dressings, organize the items used and record the operation situation. Throughout the entire demonstration, trainees should pay attention to aseptic principles and operation norms to ensure the completeness of the process. Through repeated practice of this model, learners can become familiar with the key steps and technical points of vas deferens ligation, laying a solid foundation for the independent implementation of clinical surgeries.
