Laparoscopy is a form of minimally invasive surgery that has demonstrated medical advantages to patients undergone surgery.

摘要

Laparoscopy is a form of minimally invasive surgery that has demonstrated medical advantages to patients undergone surgery. However, the altered depth perception and counterintuitive movements in the cavity might cause inefficient intrabdominal surgical knot-tying, potentially lengthening the surgical procedure and increasing complication risks to patients. Developments have been made in laparoscopic surgeries using robotics and smart feedback systems to form a more comprehensive cognitive depiction of the intended subject. In this study, we aim to conduct a comparative analysis between two groups - conventional forceps versus haptic feedback-enabled (termed as ‘smart’ in this study) forceps. By embedding a strain gauge sensor in the smart forceps and conjugating it with a real-time data acquisition system and input/output interface, it allowed the surgeon to gain haptic feedback without jeopardizing the surgical process. Static test was carried out on all the Square knots to determine if there was a statistically significant difference between the two groups. The two key findings shown in this study were the outcome of the comparative analysis and the observation of the failure mechanism presented in the two groups. The synergy of our findings suggests the potentiality of the haptic feedback system (HFS) in becoming a standard component of commercially available surgical robotic systems, a field that is gaining traction.
