This study introduces an effective, low-cost training model for microsurgery using discarded pig spleens. Undergraduate students successfully practiced microvascular anastomosis, demonstrating the model

Area of Science:

  • Surgical Training
  • Microsurgery Education
  • Veterinary Surgical Models

Background:

  • Microsurgical skills are crucial for surgeons.
  • Traditional training models can be costly or ethically complex.
  • There is a need for accessible, effective microsurgical training tools.

Purpose of the Study:

  • To present a novel microsurgical training model.
  • To evaluate its effectiveness for undergraduate surgical training.
  • To utilize discarded animal organs for cost-effective education.

Main Methods:

  • Undergraduate students performed splenectomy on pig spleens.
  • Vascular pedicles were dissected under microscopy.
  • Microvascular anastomosis was performed using 9.0 nylon sutures.

Main Results:

  • The training model proved effective for initial microvascular surgery practice.
  • A well-defined routine and qualified supervision contributed to success.
  • Low-cost experimental materials were utilized.

Conclusions:

  • Discarded pig spleen is an excellent, cost-effective microsurgical training model.
  • It offers realistic consistency and sensitivity for learning.
  • This model reduces the need to sacrifice new animals in early-stage training.
