A novel, low-cost surgical training model using gelatin-filled balloons effectively simulates various vascular surgical techniques. This method provides accessible practice for essential procedures like suturing and anastomoses.

Area of Science:

  • Biomedical Engineering
  • Surgical Education
  • Vascular Surgery

Background:

  • Effective surgical training requires realistic, accessible models.
  • Traditional simulation methods can be costly and complex.
  • Vascular surgery demands proficiency in intricate techniques.

Purpose of the Study:

  • To develop and present a low-cost, reproducible model for vascular surgical technique training.
  • To evaluate the model's utility in simulating key vascular procedures.

Main Methods:

  • Construction of a model using latex balloons filled with gelatin.
  • Securing the model to a board for stability.
  • Simulation of arterial sutures, anastomoses, patch placement, shunt insertion, and thromboembolectomy.
