Summary
This study presents an affordable, realistic surgical training model for fourth-degree lacerations using beef tripe and chicken. This innovative teaching tool enhances resident education through superior haptic simulation.
Area of Science:
- Surgical Education
- Anatomical Modeling
Background:
- Existing fourth-degree laceration repair models utilize beef tongue with plastic or vinyl tubing.
- A modified model was developed using readily available animal tissues for enhanced realism.
Purpose of the Study:
- To create a realistic and cost-effective surgical training model for fourth-degree laceration repair.
- To evaluate the haptic fidelity and educational value of the modified model.
Main Methods:
- Beef tripe was used to simulate the anal mucosa and tunneled through a beef tongue to represent the anal canal.
- Chicken leg muscles were incorporated to mimic anal sphincter muscles.
- The model allowed for repeated practice and creation of double-sided training units.
Main Results:
- The modified beef tongue model demonstrated excellent perceived haptic fidelity.
- Surgical residents responded positively, noting the realistic simulation provided by the animal tissues.
- The model is inexpensive, costing approximately $5-7 per unit.
Conclusions:
- The modified beef tongue model is an innovative, cost-effective, and well-received teaching tool for surgical resident education.
- It provides superior haptic simulation for practicing fourth-degree laceration repair.
- The use of beef tripe and chicken leg muscles offers a realistic alternative to existing models.
