RESUMO
BACKGROUND: Surgical reconstruction is a crucial stage in various surgeries, including pancreaticoduodenectomy, as it can significantly affect the surgical results. The objective was to design a suture force feedback (SFF) device that can precisely measure the suture force during surgical closures. Afterward, the device was used to train junior surgeons in surgical closure techniques. METHODS: The SFF was used to capture the suture force data of experienced surgeons. This data was utilized to train and assess junior surgeons. The SFF device had 2 tactile-based force sensors that measured the applied force. Whenever the applied force was not within the optimal force range, the device provided feedback to the surgeon. A workshop was conducted to train junior surgeons in surgical closure techniques to improve their suturing skills. RESULTS: Thirty-seven junior surgeons were enrolled in this training, of whom only 24 completed the 30-day training program. The pre-assessment results revealed that the force exerted by junior surgeons during suture knot-tying was uneven compared with that of the experienced surgeons, with a significant difference in the force exerted per knot throw (P = 0.005. Before the training program, junior surgeons applied a force of 3.89 ± 0.43 N, which was more than twice the force applied by experienced surgeons (1.75 ± 0.12 N). However, after completing the 30-day training program, their force improved to 2.35 ± 0.13 N. CONCLUSIONS: The SFF device was shown to be an encouraging training tool for improving the surgical closure dexterity and technique of the participating junior surgeons.
