Wound Healing Research

Background:

Atraumatic soft tissue handling is critical for effective wound healing.
Surgical simulation offers a safe environment for skill development outside the operating room.

Purpose of the Study:

To develop a novel pressure-sensing forceps with real-time biofeedback capabilities.
To evaluate the effectiveness of this device in improving surgical tissue handling skills.

Main Methods:

Seventy-eight participants performed continuous subcuticular closure on a silicone model using the Tissue Handling Trainer System.
The system recorded instances and duration of excessive pressure application.
Statistical analysis, including ANOVA with Tukey post hoc test, was employed.

Main Results:

Statistically significant reductions in duration above threshold pressure were observed between trials 1 and 3 (P < 0.001).
A 36% reduction in excessive force occurred after participants understood the study's aim, followed by a 70% reduction with audible biofeedback.
No significant difference was found between trials 3 and 4, indicating skill mastery.

Conclusions:

The Tissue Handling Trainer System, incorporating pressure-sensing forceps and biofeedback, effectively enhances surgical tissue handling skills.
This simulation-based approach can be a valuable tool in surgical training laboratories.
The technology demonstrates potential for improving patient outcomes through better surgical technique.
