Summary
This study developed a surgical simulation system for skin sutures using 3D finite element analysis. The modified S-shape suture method effectively reduced skin extrusion by 40%, improving postoperative outcomes.
Area of Science:
- Biomechanical Engineering
- Computational Surgery
- Medical Simulation
Background:
- Suturing can cause undesirable skin extrusion, impacting cosmetic results.
- Minimizing skin extrusion is crucial for optimal surgical outcomes.
- Investigating methods to determine appropriate suturing techniques is essential.
Purpose of the Study:
- To establish a surgical simulation system for skin sutures.
- To utilize a three-dimensional finite element method for simulation.
- To decrease skin extrusion through optimized suturing methods.
Main Methods:
- Developed 3D finite element models from rapid 3D surface-measuring device data.
- Prepared conventional spindle and modified S-shape models.
- Evaluated various suturing methods to reduce skin extrusion.
Main Results:
- The modified S-shape model demonstrated a 40% reduction in skin extrusion height compared to the spindle model.
- Simulation results correlated with clinical findings.
- Enabled evaluation of postoperative skin profiles.
Conclusions:
- The surgical simulation system allows for pre-operative design and evaluation of suturing methods.
- The modified S-shape suture technique is recommended for reducing skin extrusion.
- This system is expected to reduce surgeon workload and improve patient outcomes.
